From fe9f93c8518d5243ad2d691a4a2dfe1f7e35a932 Mon Sep 17 00:00:00 2001 From: Rafal Krysiak Date: Tue, 1 Sep 2026 22:21:01 +0200 Subject: [PATCH 1/6] validate inbound input with Ajv Adds schema validation on the MCP transports (stdio + HTTP), the tools config, and the GUI server routes, as evidence of input validation for the SOC2 audit. Ajv because the MCP tool schemas are already JSON Schema and are advertised to clients verbatim, so there is no second definition to drift. `env` is no longer required on tools that authenticate: resolveAuth also accepts explicit credentials, MPKIT_* env vars, or the default .pos entry. --- CLAUDE.md | 58 ++++- lib/proxy.js | 6 +- lib/server.js | 61 ++++- lib/validation/index.js | 106 +++++++++ lib/validation/schemas/gui.js | 78 +++++++ mcp-min/__tests__/constants.test.js | 12 +- mcp-min/__tests__/data.import.test.js | 4 +- .../__tests__/tools-config-validation.test.js | 99 ++++++++ .../__tests__/transport-validation.test.js | 148 ++++++++++++ mcp-min/__tests__/uploads.push.test.js | 3 +- mcp-min/__tests__/validate-params.test.js | 97 ++++++++ mcp-min/constants/list.js | 5 +- mcp-min/constants/set.js | 4 +- mcp-min/constants/unset.js | 4 +- mcp-min/data/import-status.js | 4 +- mcp-min/data/import.js | 3 +- mcp-min/data/validate-tool.js | 2 +- mcp-min/http-server.js | 23 ++ mcp-min/schemas/auth.js | 19 ++ mcp-min/stdio-server.js | 22 ++ mcp-min/tests/run.js | 4 +- mcp-min/tools.js | 28 ++- mcp-min/uploads/push.js | 4 +- mcp-min/validate-params.js | 34 +++ package-lock.json | 2 + package.json | 2 + test/unit/server.validation.test.js | 215 ++++++++++++++++++ test/unit/validation.test.js | 94 ++++++++ 28 files changed, 1117 insertions(+), 24 deletions(-) create mode 100644 lib/validation/index.js create mode 100644 lib/validation/schemas/gui.js create mode 100644 mcp-min/__tests__/tools-config-validation.test.js create mode 100644 mcp-min/__tests__/transport-validation.test.js create mode 100644 mcp-min/__tests__/validate-params.test.js create mode 100644 mcp-min/schemas/auth.js create mode 100644 mcp-min/validate-params.js create mode 100644 test/unit/server.validation.test.js create mode 100644 test/unit/validation.test.js diff --git a/CLAUDE.md b/CLAUDE.md index 39f94220..6401fd45 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -81,7 +81,8 @@ pos-cli/ │ ├── data/ # Import/export/clean │ ├── assets/ # Asset deployment │ ├── logsv2/ # OpenObserve logs integration -│ └── validators/ # Input validation +│ ├── validation/ # Ajv schema validation (shared by GUI + MCP) +│ └── validators/ # CLI argument validators (url, email, paths) ├── mcp-min/ # MCP server implementation │ ├── index.js # Starts stdio + HTTP/SSE transports │ ├── stdio-server.js # MCP over stdio (for editor integrations) @@ -397,6 +398,61 @@ Can run with sync: `pos-cli gui serve staging --sync --open` - **ora** - Loading spinners - **yeoman-generator** - Code generators +## Input Validation (Ajv) + +**Key files**: `lib/validation/index.js`, `lib/validation/schemas/gui.js`, `mcp-min/validate-params.js`, `mcp-min/schemas/auth.js` + +Untrusted input is validated against JSON Schema with **Ajv** (draft-07) before it reaches +any handler.

It also relaxes `required: ['env']` on tools that authenticate, because `resolveAuth` supports three other call styles. + +The design is right and should not change: validating each MCP tool's own `inputSchema` means the schema advertised in `tools/list` and the schema enforced are the same object, so there is no second definition to drift. `allowUnionTypes` is genuinely required (verified: `logsSearchSchema.query` is the only schema that needs it). The new tests do bite — six independent mutations of the production code each broke tests as intended. + +Everything below lives in the code and tests this branch introduces. It is one task because shipping any of it would either break a user-visible feature or leave the branch's own stated contract unenforced. + +## 1. Blocker: the admin GUI Logs page returns 400 on every load + +`lib/validation/schemas/gui.js` types the log cursor as `{ type: 'integer', minimum: 0 }`. The client that actually calls the route (`gui/next/src/lib/api/logs.js:18-20`) sends the literal string `null` when there is no cursor: + +```js +const last = args.last ?? null; +return fetch(`${url}?lastId=` + last) // -> ?lastId=null +``` + +`routes/logs/+page.svelte:41` seeds that value from `$state.logs.logs?.at(-1)?.id ?? null`, so the first poll always sends it. Ajv does not coerce `"null"` to an integer. Verified against a running `lib/server.js`: + +``` +GET /api/logs?lastId=null -> 400 {"error":"Invalid request: /lastId must be integer"} +``` + +`logs.get` swallows the rejection into `{ error }`, so the page renders empty with no indication why. `?lastId=` (empty) is rejected the same way. + +The schema comment in `gui.js:56` shows the root cause: the constraint was derived from `lib/test-runner/logStream.js` rather than from the client that calls the route. The preferred fix is client-side (`args.last ?? 0` — `0` is already the "from the beginning" sentinel that `logStream.js` uses) plus a `gui/next` rebuild, since `gui/next/build` is committed and shipped in the npm package. Normalising empty/`null`/`undefined` away inside the route is acceptable only as a compatibility shim for already-installed GUI builds, and must be commented as such. + +The same field is typed `integer` here but `string` in `mcp-min/logs/fetch.js:15` and `mcp-min/logs/stream.js`. Pick one, or document why they differ. + +## 2. The "one schema, no drift" claim is broken by a third default + +Three different objects now describe "this tool declares no schema": `{ type: 'object', properties: {} }` in the stdio tools/list (`stdio-server.js:52`), `{ type: 'object', additionalProperties: true }` in the HTTP tools/list (`http-server.js:175`), and `{ type: 'object' }` in the enforcement path (`validate-params.js:6`). The first two predate the branch; the branch added the third, which is the one actually enforced. Hoist a single exported constant and use it at all three sites. `envs-list` (`mcp-min/tools.js:100`) is the only tool without `additionalProperties: false` — now that schemas are enforced, close it like the others. + +## 3. `validate()` mislabels two non-schema failures as schema-compile failures + +`result.schemaError` maps to HTTP 500 / JSON-RPC `-32603` at four call sites. Two failures are wrongly routed there: + +``` +validate({type:'object'}, {}, {mode:'nope'}) -> schemaError: "Schema failed to compile: Unknown validation mode: nope" +validate(true, {x:1}) -> schemaError: "Schema failed to compile: Invalid value used as weak map key" +``` + +The first is a caller programming error, not a schema defect. The second is a *legal* boolean JSON Schema that dies in the WeakMap cache at `lib/validation/index.js:45` because primitives cannot be WeakMap keys. Neither is reachable from today's schemas; both are traps for the next person. Also, `validate()` returns a `data` field that no caller reads — drop it or use it. + +## 4. The `env`-optional rule is unenforced for 15 of 22 tools + +CLAUDE.md states that any tool closing its schema with `additionalProperties: false` must also declare `url`/`email`/`token`, or the explicit-credentials path in `resolveAuth` becomes unreachable. Every tool satisfies this today (checked all 22 that call `resolveAuth`), but the test that guards it (`mcp-min/__tests__/validate-params.test.js:64-72`) uses a hand-written list of 7 tool names. Proof the guard does not hold: stripping `url`/`email`/`token` from `mcp-min/migrations/list.js` — a tool that calls `resolveAuth` — leaves all 338 mcp-min tests passing. Replace the list with an invariant derived from the tool registry so tools added later are covered automatically. + +Related: `mcp-min/schemas/auth.js` is applied to only 6 tools (`constants/*`, `data/import*`, `uploads/push`); the other 16 duplicate the three properties inline and, unlike the shared fragment, ship no `description` for them, so `tools/list` documents the same parameters inconsistently. Apply the fragment everywhere or delete it. + +## 5. `ajv-formats` is a dead runtime dependency + +`addFormats(ajv)` is called but no schema in the repo uses the `format` keyword (`mcp-min/check/index.js:17` is a property *named* `format`, not the keyword). Either drop the dependency or use it — `format: 'email'` / `'uri'` on the shared auth properties is the obvious missing half, given `lib/validators/email.js` and `lib/validators/url.js` already enforce that for CLI arguments. + +## 6. "The tools config fails closed" is only half true + +A config naming a tool that does not exist is silently ignored, which is exactly the outcome the new throw was added to prevent. Verified: `MCP_TOOLS_CONFIG = {"tools":{"deploy-strt":{"enabled":false}}}` starts the server with `deploy-start` still enabled and all 35 tools exposed. The schema cannot catch this because it cannot enumerate tool names; `applyConfig` (`mcp-min/tools.js:183`) iterates the registry and never inspects config keys. Add a pass over `Object.keys(config.tools)` that rejects (or at minimum loudly warns about) names with no matching tool. + +Separately, the throw itself reaches the user as a raw Node stack trace, doubled with the `log.error` line above it (`[ERROR] invalid tools config at …` followed by `Error: Invalid tools config at …` and 6 module-loader frames). Exit code is 1, which is correct, but the output contradicts CLAUDE.md's own error-handling guidance ("user-friendly error messages… log to logger for consistent formatting"). Catch at the `bin/pos-cli-mcp.js` boundary and report through `logger.Error`. + +## 7. Documented `resolveAuth` precedence is wrong + +The new CLAUDE.md section states the order as "explicit params, then `MPKIT_*` env vars, then the named `.pos` environment, then the first `.pos` entry". `mcp-min/auth.js:33-56` actually resolves: explicit params -> **named `.pos` environment** -> `MPKIT_*` -> first `.pos` entry. The same wrong order appears in the comment at `mcp-min/__tests__/validate-params.test.js:61`. CLAUDE.md is the file future agents follow, so this needs to be right. (The stale JSDoc in `auth.js` it was copied from is tracked separately.) + +Also worth a line in the affected tool descriptions: because `env` is now advertised as optional, an MCP client that omits it lands on the *first* `.pos` entry for mutating tools (`data-import`, `constants-set`, `uploads-push`). Runtime behaviour is unchanged — nothing enforced `required` before — but the advertised contract now invites the omission. + +## 8. Coverage gaps in the new tests + +- The `schemaError` -> 500 / `-32603` branch is untested at all four call sites. +- `test/unit/validation.test.js:89` ("compiles each schema once and reuses it") validates twice and asserts both are valid. It asserts nothing about caching. +- In `mcp-min/__tests__/tools-config-validation.test.js`, the `test.each` case for a bare `null` config passes for the wrong reason: with the throw removed it still fails, because `applyConfig` then dereferences `null`.

Also: the auth invariant is now derived from the tool registry rather than a hand-written list, which it had silently stopped guarding; the tools config rejects entries naming a tool that does not exist, and reports through the logger instead of a stack trace; and validate() no longer reports an unknown mode or a boolean schema as a compile failure. --- CLAUDE.md | 60 +++-- bin/pos-cli-mcp.js | 16 +- gui/next/src/lib/api/logs.js | 4 +- lib/proxy.js | 8 +- lib/server.js | 8 + lib/validation/index.js | 29 ++- lib/validation/schemas/gui.js | 13 +- mcp-min/__tests__/constants.test.js | 7 +- mcp-min/__tests__/data.import.test.js | 2 +- .../__tests__/tools-config-validation.test.js | 60 +++++ .../__tests__/transport-validation.test.js | 227 ++++++++++++++---- mcp-min/__tests__/uploads.push.test.js | 3 +- mcp-min/__tests__/validate-params.test.js | 104 ++++++-- mcp-min/data/clean-status.js | 5 +- mcp-min/data/clean.js | 5 +- mcp-min/data/export-status.js | 5 +- mcp-min/data/export.js | 5 +- mcp-min/deploy/start.js | 5 +- mcp-min/deploy/status.js | 5 +- mcp-min/deploy/wait.js | 5 +- mcp-min/graphql/exec.js | 5 +- mcp-min/http-server.js | 38 +-- mcp-min/liquid/exec.js | 5 +- mcp-min/logs/fetch.js | 7 +- mcp-min/logs/stream.js | 7 +- mcp-min/migrations/generate.js | 5 +- mcp-min/migrations/list.js | 5 +- mcp-min/migrations/run.js | 5 +- mcp-min/schemas/auth.js | 22 +- mcp-min/schemas/default.js | 18 ++ mcp-min/stdio-server.js | 22 +- mcp-min/sync/single-file.js | 5 +- mcp-min/tests/run-async-result.js | 5 +- mcp-min/tests/run-async.js | 5 +- mcp-min/tests/run.js | 5 +- mcp-min/tools-config-error.js | 16 ++ mcp-min/tools.js | 75 +++--- mcp-min/validate-params.js | 37 ++- test/unit/server.validation.test.js | 96 +++++++- test/unit/validation.test.js | 39 ++- 40 files changed, 776 insertions(+), 222 deletions(-) create mode 100644 mcp-min/schemas/default.js create mode 100644 mcp-min/tools-config-error.js diff --git a/CLAUDE.md b/CLAUDE.md index 6401fd45..4b190fce 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -400,7 +400,8 @@ Can run with sync: `pos-cli gui serve staging --sync --open` ## Input Validation (Ajv) -**Key files**: `lib/validation/index.js`, `lib/validation/schemas/gui.js`, `mcp-min/validate-params.js`, `mcp-min/schemas/auth.js` +**Key files**: `lib/validation/index.js`, `lib/validation/schemas/gui.js`, +`mcp-min/validate-params.js`, `mcp-min/schemas/auth.js`, `mcp-min/schemas/default.js` Untrusted input is validated against JSON Schema with **Ajv** (draft-07) before it reaches any handler.

The shim is therefore what actually fixes the page for users today, and the source fix is dormant until someone runs `npm run build` in `gui/next`. That is the right trade (a SvelteKit rebuild would churn every hashed asset filename), it is documented in the code, and both shapes are covered by tests. + +## Verified by mutation, not just by reading + +Each mutation applied to production code, suite run, mutation reverted: + +- strip `...authProperties` from `mcp-min/migrations/list.js` (a tool the old hand-written list never named) → 2 failures, one naming the file. The invariant now scans `mcp-min/**` for `resolveAuth(` with fast-glob, so a tool added later is covered the moment it authenticates. This was the escape proven in the review. +- flatten `rejectionFor`'s status mapping to a constant 400 / -32602 → 4 failures, one per MCP dispatch path. +- flatten `rejectInvalid`'s mapping in `lib/server.js` to a constant 400 → **0 failures**. See carried-forward item below. + +## Criterion-by-criterion + +1, 2 — cursor accepted in every shape the GUI sends; typed `integer` consistently in `gui.js`, `mcp-min/logs/fetch.js` and `mcp-min/logs/stream.js`. +3, 4 — `OPEN_OBJECT_SCHEMA` in the new `mcp-min/schemas/default.js`, imported by both `tools/list` responses and `validate-params.js`; `envs-list` closed with `additionalProperties: false`. +5, 6 — unknown mode now throws `RangeError`; boolean schemas skip the WeakMap and validate normally; `data` removed from the return. All three asserted. +7, 8 — every one of the 22 `resolveAuth` tools spreads `authProperties`; no inline `url`/`email`/`token` triple remains anywhere. +9 — `ajv-formats` is now earned: `format: 'uri'` and `format: 'email'` on the shared auth properties. This matches `lib/validators/url.js`, which already requires a parseable absolute URL, so the CLI and MCP surfaces now agree. +10, 11 — `loadToolsConfig` rejects config keys matching no registered tool, using `hasOwnProperty` rather than `in` (with the reasoning in a comment), and names every unknown key. New `ToolsConfigError` caught at the `bin/pos-cli-mcp.js` boundary and reported through `logger`; a test asserts exit 1, the message present, and no stack frames or `node:internal` in the output. +12 — CLAUDE.md now states the real precedence (params → named `.pos` → `MPKIT_*` → first entry) and adds the first-`.pos`-entry warning to the descriptions of `data-import`, `constants-set`, `constants-unset` and `uploads-push` in `tools.config.json`. +14 — the compile-once test now counts schema property reads through a Proxy and asserts the second call reads nothing. It actually measures caching. +15 — the bare-`null` config case now asserts `must be object` and `not.toContain('TypeError')`, so it can no longer pass on the incidental `applyConfig` crash. +16 — added: stdio legacy direct invocation in both its JSON-RPC and bare `{ id, error }` shapes, `/call-stream` legacy streaming (including a `content-type: application/json` assertion, proving rejection precedes the SSE handshake), `logsv2` query-as-object and query-as-string, scalar-into-string-union coercion, a union miss, POST-body coercion, and a `searchAround` payload. +17 — `startHttp({ port: 0 })` with `server.address().port`. +18 — `required` assertions are now uniformly `toEqual([...])` or `toBeUndefined()`, plus a dedicated "required relaxations" block covering `data-validate` and `unit-tests-run`. + +## Found and fixed beyond the task + +Tightening `logs-fetch.lastId` to `integer` (criterion 2) would have broken the tool's own paging: the handler returned the cursor as a string, which the schema it advertises would then reject with -32602. The fix returns `Number(latestId)` and adds a round-trip test that feeds the returned cursor back through validation. `latestId` is only ever assigned a numeric string, so there is no NaN path. + +Worth a release note: `logs-fetch.lastId` and `logs-stream.startLastId` changed type from `string` to `integer`, and `envs-list` now rejects unknown parameters. MCP clients read `tools/list` per session so they adapt automatically, but a hard-coded caller sending `lastId: "42"` will now get -32602. + +## Carried forward + +**Criterion 13 — partially met.** Three of the four `schemaError` sites are genuinely covered via a test-only tool with an uncompilable schema, mutation-verified. The GUI leg is not: the "uncompilable schema on a GUI route" block in `test/unit/server.validation.test.js` builds a throwaway express app and reimplements the status expression inline, so it never exercises `lib/server.js`. Flattening the real `rejectInvalid` mapping to 400 passes all 32 tests in that file. Tracked as TASK-3.1. Left as a follow-up rather than a blocker because no schema in the repo fails to compile, so the branch is unreachable in practice — it is regression protection for a rule CLAUDE.md itself notes is written in two places. + +**Criterion 19 — deviation accepted.** Both code lines originally flagged in `mcp-min/http-server.js` are now within 120 characters. Four new lines exceed it, all of them single-quoted `description:` string literals in tool definitions, in files where `master` already carries description lines of 150–320 characters (`liquid/exec.js:7` is 317). Wrapping them would need string concatenation that no other tool uses. Flagged rather than silently accepted; reopen if the repo ever adopts a linter that enforces `.editorconfig`. + +**One stale comment.** `lib/validation/schemas/gui.js` still reads "The same field is declared `integer` here but `string` on the MCP logs tools" — both are now `integer`, which the same sentence goes on to say. Reads as a description of the change rather than of the code. Cosmetic. + +**Docs/test tension.** CLAUDE.md says "a tool with no schema accepts any object", but `validate-params.test.js` asserts `inputSchema.type === 'object'` for every registered tool, so such a tool would fail the suite. Both are defensible; they just do not agree about whether a schema is optional. + +## Suite status + +`mcp-min/__tests__` + `test/unit`: **1605 passing, 6 skipped, 1 failing** — `modules.test.js > publishVersion() … single-dir workflow`, reproduced identically on a clean `master` worktree and tracked as TASK-9. Up from ~1491 tests before the fix. + +Scope was respected exactly: TASK-4 through TASK-12 are untouched. Confirmed by inspection — no error middleware in `lib/server.js`, all six `tools[name]` / `mcpHandlers[method]` dispatch lookups still unguarded, `bin/pos-cli-mcp-config.js` still does not validate, `mcp-min/auth.js` JSDoc still has the wrong order, and `gui/next/src/lib/api/logsv2.js` untouched. The `hasOwnProperty` fix in commit a16db70 hardens config-key lookup, which is a different site from TASK-5's dispatch lookups, so there is no overlap. + diff --git a/backlog/tasks/task-3.1 - Pin-the-GUI-servers-schemaError-status-mapping-with-a-test-that-exercises-lib-server.js.md b/backlog/tasks/task-3.1 - Pin-the-GUI-servers-schemaError-status-mapping-with-a-test-that-exercises-lib-server.js.md new file mode 100644 index 00000000..b58667bb --- /dev/null +++ b/backlog/tasks/task-3.1 - Pin-the-GUI-servers-schemaError-status-mapping-with-a-test-that-exercises-lib-server.js.md @@ -0,0 +1,52 @@ +--- +id: TASK-3.1 +title: >- + Pin the GUI server's schemaError status mapping with a test that exercises + lib/server.js +status: To Do +assignee: [] +created_date: '2026-09-02 14:16' +labels: + - tests + - validation + - gui +dependencies: [] +references: + - lib/server.js + - test/unit/server.validation.test.js + - mcp-min/__tests__/transport-validation.test.js + - mcp-min/validate-params.js +parent_task_id: TASK-3 +priority: low +ordinal: 28000 +--- + +## Description + + +Carried forward from TASK-3, acceptance criterion 13 ("the schemaError branch is covered by a test at each of the four sites").

Mutation-verified: flattening the mapping in `rejectionFor` to a constant 400 / -32602 fails 4 tests. + +The GUI server keeps its own copy of the mapping in the `rejectInvalid` closure inside `lib/server.js` (CLAUDE.md notes the two "apply the same 400/500 rule and have to be changed together"). The test that claims to cover it — `test/unit/server.validation.test.js`, describe block "uncompilable schema on a GUI route" — builds a throwaway express app and calls `validate()` plus its own inline status expression. It never touches `lib/server.js`. Mutation-verified: replacing + +```js +const status = result.schemaError ? 500 : 400; // lib/server.js +``` + +with `const status = 400;` leaves all 32 tests in that file passing. + +So the duplicated rule is pinned on one side only, and the side that is not pinned is the one that duplicates it. + +The straightforward approach is to make the real route see an uncompilable schema — `vi.mock('#lib/validation/schemas/gui.js')` in a dedicated test file, returning a schema Ajv cannot compile for one of the five routes, then assert the route answers 500 and does not forward to the mocked Gateway. A separate file is needed because the existing suite depends on the real schemas. Replacing the throwaway-app test with that closes the gap; the alternative — exporting `rejectInvalid` so it can be tested directly — would also work but widens the module's surface for a test. + +Not urgent: no schema in the repo fails to compile today, so the 500 branch is unreachable in practice.
