The platform enum covers the 16 platforms above (see src/platform-routing.ts). The package also provides run_tool for direct tool calls; availability depends on the platform API and connected account.
See integrations for platform details. For MCP discovery, server.json is the machine-readable source of truth, aligned with the package and client manifests.
- Read Access: Unlimited read, reporting, audit, and attribution queries across all connected ad platforms (0% ad spend markup).
- Verified Writes: $0.25 per verified write, 0% of ad spend.
- Scale ($500/mo): 5 seats, multi-workspace isolation, dedicated concurrency, and team governance. See pricing for full plan details.
Synter provides workspace spend limits, launch preflight (dry_run: true), post-write readback, and an immutable audit log. Review the intended account, budget, and action before a live write. Client confirmation behavior depends on the MCP client and its configuration.
For local read-only access, pass --read-only or set SYNTER_READ_ONLY=true to remove mutating tools and block write calls locally. Use --demo to explore mock data without an account or API key.
For SaaS products, agencies, and engineering teams embedding ad operations across multiple customers or brands, Synter provides both MCP and a direct REST API + native SDKs:
- Programmatic Tenant / Workspace Provisioning (
/api/v1/workspaces):- Create and manage isolated tenant workspaces via REST (
POST https://synterai.com/api/v1/workspaces) or target a specific tenant per request withSYNTER_WORKSPACE_ID/X-Synter-Workspace: ws_.... Each workspace maintains strict tenant isolation over OAuth token vaults, ad account IDs, daily spend caps, and audit logs.
- Create and manage isolated tenant workspaces via REST (
- Server-Side Scoped API Keys (
tools:read,budget:decrease,tools:write):- In addition to client-side
--read-onlymode, Synter enforces server-side API key scopes minted viaPOST /api/v1/workspaces/{id}/keysor synterai.com/developer:tools:read— server-enforced read-only access (reporting, search term audits, attribution, diagnostics; all mutations rejected server-side with403).budget:decrease— allows agents to pause bleeding campaigns or lower budgets while blocking budget increases or new campaign launches.tools:write— full write and campaign creation access within workspace budget guardrails.
- In addition to client-side
- White-Label OAuth Link Flow & Bring-Your-Own (BYO) OAuth Apps (
/api/v1/oauth):- Embedded / White-Label OAuth: Generate per-tenant authorization URLs (
POST https://synterai.com/api/v1/oauth/{platform}/authorizewithworkspace_idand customredirect_uri) so your end users connect Google, Meta, LinkedIn, Reddit, TikTok, or DSP accounts inside your app without visiting Synter's UI, with automatic token refresh and credential vaulting. - BYO OAuth App / Credentials: Register your own platform OAuth client ID/secret and developer tokens per workspace, or pass credentials directly via the SDK/CLI (
SYNTER_BYO_CREDENTIALS=true).
- Embedded / White-Label OAuth: Generate per-tenant authorization URLs (
- REST API & Official Multi-Language SDKs:
- Call any tool over HTTP (
POST https://synterai.com/api/v1/tools/executewithAuthorization: Bearer syn_...orX-Synter-Key: syn_...) or via the official typed SDKs:- TypeScript / Node.js (
@synterai/sdk-js):import { SynterClient } from "@synterai/sdk-js"; const synter = new SynterClient({ apiKey: process.env.SYNTER_API_KEY, workspaceId: "ws_tenant_123" }); const campaigns = await synter.campaigns.list({ platform: "google", dateRange: "LAST_30_DAYS" }); const preview = await synter.campaigns.updateBudget({ platform: "linkedin", campaignId: "123", dailyBudget: 150, dryRun: true });
- Python (
pip install synter):from synter import Synter client = Synter(api_key=os.environ["SYNTER_API_KEY"], workspace_id="ws_tenant_123") perf = client.performance.get(platform="meta", date_range="LAST_14_DAYS")
- Rust (
cargo add synter-sdk) & Java (ai.synter:synter-sdkon Maven Central).
- TypeScript / Node.js (
- Call any tool over HTTP (
Use this when your client only speaks stdio, or when you run headless and can't complete a browser sign-in.

}HTTP clients that need a header instead of OAuth (n8n, Zapier, scripts, other headless clients):
URL: https://mcp.synterai.com
Header: X-Synter-Key: syn_your_api_key_here
The header is optional; browser OAuth is the default. Works with any MCP client that supports Streamable HTTP transport.
Restart your AI client and start chatting.
This package is the raw MCP server. If you use Claude Code or Claude Desktop, the Synter plugin wraps this same server with ready-made skills (/synter:launch, /synter:audience, /synter:optimize, …), specialized agents, and workflow guidance:
/plugin marketplace add Synter-Media-AI/plugin
/plugin install synter@synter
It also ships a headless Claude Agent SDK runner for automation. See the plugin repo or the Claude Plugin guide. Use this MCP package directly when you want just the tools, or are wiring another client.

The npx package and the hosted server at https://mcp.synterai.com name a few equivalent tools differently:
stdio (@synterai/mcp-server) |
Hosted (https://mcp.synterai.com) |
|---|---|
get_performance (with platform) |
pull_<platform>_ads_performance, e.g. pull_google_ads_performance, pull_meta_ads_performance |
get_daily_spend |
No single hosted tool; use pull_<platform>_ads_performance (Google supports segment: "date" for per-day rows) |
list_ad_accounts |
list_connected_accounts |
As of the next hosted release, the hosted server also accepts the stdio names above as aliases, so the same tool calls work against either transport.
If you've never run ads before, here's what you need to know:
A campaign is like a project folder. It contains your ads, who sees them, and how much you spend.
Campaign: "Q1 Lead Generation"
├── Budget: $50/day
├── Targeting: USA, people searching "project management"
└── Ads: Headlines, descriptions, images
| Platform | Best For | Min Budget |
|---|---|---|
| Google Ads | People actively searching for your product | $10/day |
| Meta (Facebook/Instagram) | Visual products, broad audiences | $5/day |
| B2B, enterprise, job seekers | $25/day | |
| Niche communities, tech-savvy users | $5/day | |
| Microsoft (Bing) | Older demographics, B2B | $10/day |
| TikTok | Gen Z, entertainment, e-commerce | $20/day |
Search Campaigns: Your ad shows when someone Googles specific keywords.
- Example: Someone searches "best CRM software" → Your ad appears
Display Campaigns: Image ads shown across websites and apps.
- Example: Banner ad on a news site
Performance Max (PMax): Google's AI shows your ads everywhere (Search, YouTube, Display, Gmail, Maps).
- Example: Google figures out the best placements for you
Video Campaigns: Video ads on YouTube and partner sites.
- Example: 15-second ad before a YouTube video
| Term | What It Means |
|---|---|
| Impressions | How many times your ad was shown |
| Clicks | How many people clicked your ad |
| CTR | Click-through rate (clicks ÷ impressions × 100) |
| CPC | Cost per click |
| Conversions | Desired actions (signups, purchases, etc.) |
| ROAS | Return on ad spend (revenue ÷ spend) |
Before creating your first campaign, you'll need:
- ✅ A landing page URL where people will go when they click
- ✅ An idea of who you want to reach (location, interests)
- ✅ A daily budget you're comfortable with ($10-50 to start)
- ✅ Some headlines and descriptions for your ad
Pro tip: Start with a Search campaign on Google. It's the easiest to understand and shows ads to people already looking for what you offer.
You: Create a Google Search campaign for my SaaS product. Target people searching for "team collaboration software" and "project management tools". Budget is $25/day. Landing page is https://myapp.com/signup
Agent: I'll create a Search campaign with those keywords. What headlines should I use? Here are some suggestions:
- "Team Collaboration Made Simple"
- "Project Management for Modern Teams"
- "Book a Demo Today"
You: How are my campaigns doing this week?
Agent: Here's your performance for the last 7 days:
Campaign Spend Clicks Conversions ROAS Brand Search $142 89 12 4.2x Competitor Keywords $98 45 3 1.5x Display Retargeting $67 234 8 2.8x The "Competitor Keywords" campaign is underperforming. Want me to pause it or adjust the targeting?
You: I'm getting clicks for "project management jobs" but we're not hiring. Block those.
Agent: Added "jobs" as a negative keyword to your campaign. This will stop your ads from showing for any search containing "jobs".
You: I need a display ad image for a marketing automation product. Dark theme, professional, 1200x628.
Agent: Generating your image...
Created: "Marketing automation dashboard with data visualization on dark background" Asset saved and ready to use in your next Display campaign.
To manage ads on each platform, you'll need to connect your accounts in Synter:
- Go to synterai.com/integrations
- Click "Connect" next to each platform
- Complete the OAuth flow
- Your agent can now manage that platform
See Supported ad platforms for the 16 ad platforms with verified write and create. Write/create depth varies by platform API.
For power users, you can call any of 140+ Synter tools directly:
> Use run_tool to call google_ads_list_audiences
See the full tool list at docs.synterai.com/mcp/tools or ask your agent:
> What tools are available for LinkedIn Ads?
Client confirmations depend on the client's handling of tool annotations and its settings. Use launch preflight, check workspace spend limits, and verify live changes with readback and the audit log. Use dry_run: true where the tool schema supports it to preview a request before execution.
| Variable | Required | Description |
|---|---|---|
SYNTER_API_KEY |
Yes (stdio) | Your Synter API key, from synterai.com/developer |
SYNTER_API_URL |
No | API base URL override (default https://synterai.com) |
SYNTER_ARTIFACT_API_URL |
No | Artifact API override used by stage_audience_artifact (default https://api.synterai.com) |
These apply to the local npx server only. The hosted server at https://mcp.synterai.com uses browser OAuth and needs no environment variables.
# Clone and install

npm run build
# Run locally
SYNTER_API_KEY=syn_your_key_here node dist/index.jsMost clients open the sign-in page the first time a Synter tool is used. In Codex, run codex mcp login synter-ads. If your client can't do a browser sign-in at all, use the X-Synter-Key header fallback described in Local stdio (npx) / API-key fallback.
Make sure your API key is in the env section of your MCP config. The key should start with syn_.
- Check that you copied the full key (they're long!)
- Verify the key is active at synterai.com/developer
- Make sure the key has
tools:writescope
You need to connect at least one ad platform:
- Go to synterai.com/integrations
- Click "Connect" next to Google Ads (or another platform)
- Complete the OAuth authorization
- Restart your AI client completely (not just refresh)
- Check the MCP server logs for errors
- Verify the config file path and JSON syntax
Yes. Synter supports Google Ads reporting, Search, Display, and Performance Max campaign creation, keywords, budget updates, audience management, and conversion tracking. Google Ads is one of the 16 platforms with verified write and create; write/create depth varies by platform API.
Yes. Add https://mcp.synterai.com as a custom connector and complete OAuth 2.1 browser sign-in. Synter supports ad operations across 16 ad platforms with verified write and create, with depth varying by platform API. No API key is needed for hosted access.
