Connect a client

• Sign in and approve. ChatGPT, claude.ai and Claude Desktop’s connector settings connect this way. They need no key.
• An API key. Claude Code, Cursor and other clients that send a header connect this way.

Sign in and approve

What the page checks

• Only an admin approves. A member sees who to ask, and may deny the request.
• The request works in the browser the assistant opened. A link to the page that somebody forwards does not work in another browser.
• The destination comes first. An app names itself, but the page leads with the address its answers go to. If the name and the address do not match, the page warns you. Deny unless you added that app yourself.
• An organization with no project cannot connect. Start a trial first.

How a connection ends

• an admin revokes it on that card. The card asks first, and the next call fails at once.
• that admin leaves the organization, another admin removes them, or they stop being an admin.
• the organization is deleted.
• the assistant stays unused until its sign-in expires. Connect it again from the assistant.

An API key

• The endpoint: https://mcp.fullreach.ai. Settings, Organization, API keys shows it with a Copy button.
• An API key. An admin creates it on the same card. Name it after the client, such as “Cursor”. Under Access, choose Read and write only for a key that needs write access. The key shows once, so copy it before you close the panel. It starts with fr_.

Claude Code

claude mcp add --transport http fullreach https://mcp.fullreach.ai --header "Authorization: Bearer fr_…"

Claude Desktop with a key

1. Install Node.js, if it is not installed.
2. In Claude Desktop, open Settings, Developer, Edit Config.
3. Add the server to claude_desktop_config.json, with your key in place of fr_…:

{
  "mcpServers": {
    "fullreach": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.fullreach.ai", "--header", "Authorization:${FULLREACH_AUTH}"],
      "env": {
        "FULLREACH_AUTH": "Bearer fr_…"
      }
    }
  }
}

4. Quit Claude Desktop completely and open it again.

Cursor

{
  "mcpServers": {
    "fullreach": {
      "url": "https://mcp.fullreach.ai",
      "headers": {
        "Authorization": "Bearer fr_…"
      }
    }
  }
}

Other clients

Write access

• An admin grants it, once. For a connection, the assistant asks for it, and the admin selects the box on the approval page. For a key, the admin chooses Read and write under Access when creating the key. To change it later, create a new key or approve a new connection, and revoke the old one.
• Without it, a credential only reads. Its assistant does not see the write tools. A call to one returns a sentence that says how to get write access.
• The assistant asks before each write. Each write tool says so, and the project_tune_up prompt proposes changes and waits for a yes.
• A call is all or nothing. If the server refuses one item, it writes nothing.

Add the manual beside it

claude mcp add --transport http fullreach-docs https://docs.fullreach.ai/mcp

Limits

• Plan limits states how many tool calls an organization may make a minute. Keys and connections share it. Every answer carries the rate-limit headers, so a client can pace itself.
• A key or a connection reaches only this organization. It never reaches the dashboard. Without write access, it cannot change anything.
