Does Keyword.com MCP cost extra?
Community (free)
The Keyword.com MCP server is community-built — free to run, but you still pay for your Keyword.com subscription.
- Community MCPs are normally self-hosted from a GitHub repo. There's no extra license fee.
- Your Keyword.com account still needs whatever plan is required to access the data the MCP server queries.
- Trade-off: zero MCP cost, but no guarantee it'll keep working when Keyword.com changes their UI or API.

What you can do with Keyword.com from an AI agent
Three shapes of agent workflow. Pick the row that matches how you actually use Claude / Cursor / Codex day to day.
INDIE / SOLO
Skip the dashboard, ask Claude
- "What keywords moved this week?" answered in seconds
- Quick one-off questions without leaving the editor
- Pipe Keyword.com data into your personal notes / docs without writing a script
Effort: 30 seconds — paste the config, restart Claude
AGENCY
Run client analysis at agent speed
- Hand the MCP server to your team — every consultant can ask Claude about any client's Keyword.com account
- Multi-account workflows without context-switching the Keyword.com UI
- Reports you'd normally spend hours on, done before standup
Effort: An afternoon — set up auth per client
IN-HOUSE TEAM
Production agent workflows
- Embed in your internal Codex / Cursor agents that triage Keyword.com data daily
- Combine with other MCP servers in a multi-step agent chain
- Constrain agents to read-only roles to keep production Keyword.com safe
Effort: Days — security review + role config
Limits and gotchas
- Fallback: the REST API works for any flow the MCP server doesn't cover.
- Rate limits: MCP calls count against your underlying Keyword.com API quota. Burst usage from a curious agent can drain a daily allowance fast.
Keyword.com MCP & API FAQ
Is the Keyword.com MCP server official?
+
No — it's a community build, not maintained by Keyword.com. Expect occasional drift and check the README before depending on it for production agents.
Can I use the Keyword.com MCP with Cursor or Codex?
+
Yes — MCP is a protocol, not Claude-specific. Any MCP-capable client (Cursor, Codex, Windsurf, Zed) can use the same server config with minor path adjustments.
