Add MatrixAgentNet agent network

[matrixagentsocial]

What this adds

Adds MatrixAgentNet to Identity & Comms as an agent-native network. Agents have persistent identities and can publish work, review other agents' contributions, and expose a public contribution history through web, MCP, and REST interfaces.

Evidence

• Agent guide: documented agent workflow and interfaces.
• Live MCP discovery document: endpoint, transport, and access model.
• Official repository: product overview and core agent interactions.

The listing uses pricing: unknown, discloses early demo activity and unverified external adoption, and leaves editorial provenance fields unset. The live MCP discovery document describes email verification for registration; please use it for current access requirements if the agent guide differs.

I maintain MatrixAgentNet and am submitting this listing for editorial review.

I found missing media metadata and/or repo-managed submitter metadata that should be written back to the PR branch. I can't push directly to forked PR branches, but you can generate the same changes locally with:

git fetch 'https://github.com/bradvin/agentfirst.directory.git' '9ea163b157db4a80e333a875f25becdf3998c75a'
git worktree add --detach '../agentfirst-base-78' FETCH_HEAD
npm run sync:tool-submitters -- --base-root-dir '../agentfirst-base-78' --submitted-by 'matrixagentsocial' --slug 'matrixagentnet'
npm run enrich:tool-assets -- --write --slug 'matrixagentnet'
git worktree remove '../agentfirst-base-78'

Then commit the updated files to this PR branch.

Policy assessment

@matrixagentsocial MatrixAgentNet otherwise clears the inclusion test: agents are the network's core participants, and the documented MCP/REST workflow materially supports persistent accounts, publishing, peer review, following, and messaging. The agent-native classification and Identity & Comms category fit are supported, and the early-adoption, authentication, reliability, security-review, and benchmark limitations are stated defensibly.

One accuracy/evidence change is required before acceptance: pricing: "unknown" conflicts with the official product homepage's current JSON-LD Offer (price: "0", priceCurrency: "USD"). Under the policy, unknown is only appropriate when current first-party sources do not establish product pricing. Please set pricing: "free" if no current paid tier exists and add a claim-level official-product-page evidence item for https://matrixagentnet.com/, or provide first-party pricing evidence and use the matching allowed value.

Evidence checked

• https://matrixagentnet.com/llms.txt — validated the email-verified registration, persistent agent account/API key, browsing, publishing, review, messaging, MCP, REST, attribution, and rate-limit claims.
• https://matrixagentnet.com/.well-known/mcp.json — validated the hosted Streamable HTTP endpoint and open-read/authenticated-write access model.
• https://github.com/matrixagentsocial/MatrixAgentNet — validated the repository claims about agent identities, publishing, structured review, following, messaging, and reputation.
• https://matrixagentnet.com/ — first-party pricing check; its structured Offer contradicts pricing: "unknown".

Checks run

• npm run validate:content — passed on head f59e7c9 merged with current main 9ea163b.
• npm test — passed, 84/84, on the same merged bytes.
• Current GitHub enrich check is failing; the existing bot comment already identifies the generated metadata gap.

No SEO evaluation or reviewer metadata commit was applied because the listing is not yet acceptable.

[matrixagentsocial]

Thanks for the specific review. I updated pricing to free, added the homepage's USD 0 Offer as claim-level first-party evidence, and generated the logo/OG and submitter metadata requested by the bot. The changes are in 6d774aa. I have not changed the product or claimed independent adoption.

Outcome: meets-policy

Policy assessment

MatrixAgentNet passes the inclusion test. Agents are the network's core participants, and the documented web, MCP, and REST workflows let them maintain identities, publish work, review peers, follow accounts, and message other agents. That supports the agent-native classification and Identity & Comms category without relying on generic compatibility or a thin wrapper. The revision resolves the prior pricing request: pricing: "free" now matches the first-party USD 0 offer, and the profile retains appropriate early-adoption, authentication, reliability, security-review, and benchmark caveats.

@bradvin This listing is ready for the inclusion decision.

Evidence checked

• MatrixAgentNet agent guide — https://matrixagentnet.com/llms.txt
  • Submitted claim: The agent guide describes persistent agent accounts, browsing creations, publishing work, posting peer reviews, and accessing the hosted MCP and REST interfaces.
  • Exact-URL check: The exact submitted URL returned HTTP 200 without redirect and documents agent registration, browsing, publishing, peer review, and the hosted MCP and REST interfaces.
• MatrixAgentNet MCP discovery document — https://matrixagentnet.com/.well-known/mcp.json
  • Submitted claim: The live discovery document identifies a hosted Streamable HTTP MCP endpoint and distinguishes open read tools from authenticated write actions.
  • Exact-URL check: The exact submitted URL returned HTTP 200 without redirect and identifies the hosted Streamable HTTP MCP endpoint, open read and registration tools, and API-key-authenticated writes.
• MatrixAgentNet product homepage — https://matrixagentnet.com/
  • Submitted claim: The official product page publishes structured Offer data with a USD 0 price for the web application; no paid product tier is established there.
  • Exact-URL check: The exact submitted URL returned HTTP 200 without redirect; its structured Offer data states price 0 in USD for the web application, and the page does not establish a paid product tier.
• MatrixAgentNet repository overview — https://github.com/matrixagentsocial/MatrixAgentNet
  • Submitted claim: The project repository describes agent identities, creation publishing, structured peer review, following, messaging, and public reputation.
  • Exact-URL check: The exact submitted URL returned HTTP 200 without redirect and documents agent identities, publishing creations, structured peer review, following, messaging, and reputation.

Correction to my previous acceptance: #78 (comment)

Policy assessment

@matrixagentsocial

The automated reassessment preserved that acceptance as unchanged. That was wrong. A broader first-party check found that the submitted githubUrl, https://github.com/matrixagentsocial/MatrixAgentNet, is a proprietary README-only stub rather than an inspectable source repository. Its tree contains only a README and .gitignore, has no declared licence, and the application paths advertised in the README are not present.

MatrixAgentNet still passes the inclusion test as an agent-native Identity & Comms product. The live website, llms.txt, and MCP metadata support persistent agent identities, publishing, peer review, following, messaging, and a free hosted offer. The blocker is the inaccurate treatment of the GitHub stub as implementation source.

Please:

1. Remove githubUrl, because the current repository is not the product's open-source implementation.
2. Remove the official-repository evidence item, or rewrite it narrowly to disclose that it is a proprietary public README with no application source in the tree.
3. Keep the live website, llms.txt, and MCP metadata as the substantive product evidence.

I am preserving the earlier acceptance comment as audit history rather than editing or deleting it. No classification, category, or pricing change is required.

I also reverted the reviewer-owned SEO/provenance commit that was made from the incorrect acceptance: matrixagentsocial@05f6292.

Checks run: content validation passed and all 84 tests passed on the revert head.

Evidence checked: https://matrixagentnet.com/, https://matrixagentnet.com/llms.txt, https://matrixagentnet.com/.well-known/mcp.json, and https://github.com/matrixagentsocial/MatrixAgentNet.

[matrixagentsocial]

Thanks for the correction — you are right. The public GitHub repository is a proprietary README-only stub, not the product's implementation source, and it should not have been cited as such.

Changes in the latest commit:

1. Removed githubUrl.
2. Removed the official-repository evidence item entirely.
3. Kept the live website, llms.txt and /.well-known/mcp.json as the only product evidence.

No change to classification, category or pricing. The limitations and unknowns still state that visible activity is demonstration activity and that independent adoption is not established.

The live product surfaces support the free pricing claim, and the early-adoption, authentication, reliability, security-review, and benchmark limitations remain appropriately bounded.

@bradvin This listing is ready for the inclusion decision.

Evidence checked

• https://matrixagentnet.com/llms.txt — returned HTTP 200 at the exact URL and supports email-verified registration, persistent accounts, browsing, publishing, peer review, following, messaging, MCP, REST, attribution, and rate-limit claims.
• https://matrixagentnet.com/.well-known/mcp.json — returned HTTP 200 at the exact URL and supports the hosted Streamable HTTP endpoint plus open-read/registration and API-key-authenticated write boundaries.
• https://matrixagentnet.com/ — returned HTTP 200 at the exact URL; its current WebApplication Offer states USD 0, and no current paid product tier was found.
• Current first-party product, discovery, governance, and repository surfaces were checked for contradictions. The public GitHub repository remains a proprietary README-only stub, but it is no longer represented as implementation source or submitted evidence.
