Majestic MCP server: setup, pricing & agent-readiness

How to connect Majestic MCP to Claude Desktop

Add this block to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows), then restart Claude Desktop. Cursor and Codex use a similar schema.

{
  "mcpServers": {
    "majestic": {
      "command": "npx",
      "args": ["-y", "<server-package-name>"],
      "env": {
        "MAJESTIC_API_KEY": "your-api-key-here"
      }
    }
  }
}
// Server source: https://github.com/MattiooFR/majestic-mcp
// Check the server's README for the exact "command" and required env vars.

Some MCP servers require an API key. Check the source page for setup: github.com/MattiooFR/majestic-mcp.

Does Majestic MCP cost extra?

Community (free)

The Majestic MCP server is community-built — free to run, but you still pay for your Majestic subscription.

Community MCPs are normally self-hosted from a GitHub repo. There's no extra license fee.
Your Majestic 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 Majestic changes their UI or API.

What you can do with Majestic 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 Majestic 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 Majestic account
Multi-account workflows without context-switching the Majestic 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 Majestic data daily
Combine with other MCP servers in a multi-step agent chain
Constrain agents to read-only roles to keep production Majestic safe

Effort: Days — security review + role config

Limits and gotchas

Community MCP — not maintained by Majestic. Check the README and last-update date before depending on it.
Fallback: the REST API works for any flow the MCP server doesn't cover.
Rate limits: MCP calls count against your underlying Majestic API quota. Burst usage from a curious agent can drain a daily allowance fast.

4/10

Agent-readiness verdict

Not ready for agent workflows. Majestic has a community MCP server and documented public API, but lacks an official MCP implementation and OpenAPI spec, making integration with Claude or Cursor unreliable and time-consuming for automated workflows.

Majestic MCP & API FAQ

Is the Majestic MCP server official?+

No — it's a community build, not maintained by Majestic. Expect occasional drift and check the README before depending on it for production agents.

Can I use the Majestic 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.

Does Majestic have a public API?+

Yes — public REST API at developer-support.majestic.com/api.
