What Moz exposes
Moz operates five distinct product surfaces under the Moz Data umbrella: Moz Pro (the SEO suite), Moz Local (local SEO listings and reviews), STAT (enterprise SERP analytics, demo-only from $360/mo for 3,000 keywords), Moz API (first-party row-billed access to 17 endpoints), and Moz Data (custom bespoke pipelines for AI model training). The underlying index spans 45.5 trillion links, 8.7 trillion URLs, 1 billion domains, 800M+ keyword suggestions, and 1.25 billion monthly keyword volumes. Domain Authority is the proprietary metric most teams know Moz for, but the deeper bet for AI-stack use cases is the Moz API: a free tier of 50 rows/month is enough to wire up exploratory agents before committing to a paid plan.
Access, auth, and limits
No first-party MCP means no first-party auth flow. Going through Composio requires three things: a Composio account, a paid Moz API plan ($20/mo Starter and up, the free tier may work for light testing but the rate limit of 1 request per 10 seconds will throttle agent workflows fast), and your Moz API key pasted into Composio's credential vault. From there, Composio brokers the requests, applies your row quota, and surfaces the responses to the connected LLM. No OAuth, no token rotation, no MCP-spec transport details published by Moz. If your security model rules out third-party brokers, the alternative is writing your own MCP wrapper around the Moz API, which is achievable in a few hundred lines but unsupported by Moz.
Where it works and what to build
Via Composio, the supported clients are whatever Composio's MCP integration layer connects to, currently Claude Desktop, Claude Code, Cursor, n8n, and a handful of others through their MCP gateway. Realistic workflows worth running: ask an agent to pull Domain Authority and link metrics for a competitor list (Fetch Site Metrics + Get Top Pages), check link status on a recovery list after a redesign (Check Link Status), or pull current quota usage before a heavy batch job (Lookup Quota Info). What you give up vs a first-party MCP: no agent-optimized response shaping, no Moz-specific tool descriptions tuned for LLM reasoning, no roadmap signal that Moz is investing in agent surfaces. Composio's wrapper is functional but it's a bridge, not a destination.
Which AI clients can use Moz MCP?
Not every AI assistant supports MCP natively. Per-client picture for Moz:
| Client | Support | Notes |
|---|---|---|
| Claude (Desktop/Web) | Third-party bridge | Via Composio broker. Requires Composio account plus the tool's API key. |
| Claude Code | Third-party bridge | Same Composio bridge as Claude Desktop. |
| ChatGPT | Third-party bridge | Via Composio MCP gateway. |
| Cursor | Third-party bridge | Via Composio bridge. |
| Codex | Not supported | No documented path through the third-party broker. |
| Windsurf | Not supported | — |
| Cline | Not supported | — |
| Gemini | API-only (custom code) | No MCP path; call the API directly from custom code. |
| n8n | API-only (custom code) | No first-party node; HTTP Request only. |
Moz also publishes a REST API
Moz publishes an API, but per-tier gating wasn't extracted automatically.
See Moz API pageLimits and gotchas
- Fallback: the REST API works for any flow the MCP server doesn't cover.
- No MCP available — until Moz ships one, use the REST API directly.
Agent-readiness verdict
Score: 4/10 on MCP-readiness. Moz has the data and the API to support agent workflows, but they haven't built the agent-facing layer themselves. Tools that ship official MCP servers (Ahrefs, Semrush, SE Ranking) are pulling ahead on the AI-stack-fit dimension. If your team is committed to Moz for Domain Authority or Moz Local, the Composio bridge works. If you're choosing a new SEO tool primarily for AI-stack fit, look at the tools with first-party MCP first.
Avoid for agent workflows. Moz Pro has public API documentation, but lacks MCP support, OpenAPI specs, and any official SDKs, making it difficult to integrate into Claude or Cursor-based automation. You'd need custom API calls with minimal framework support.
