Connect Outbind over MCP

Add Outbind's MCP server to Claude, ChatGPT, Claude Code, Cursor, VS Code or another app, sign in with OAuth and pick what it may do.

For AI agents: this page as MarkdownAll docs as Markdown

Outbind's MCP server is at:

https://app.outbind.ai/api/mcp

It uses Streamable HTTP and OAuth 2.1 sign-in. Apps register themselves, so leave any "OAuth Client ID" or "Client secret" fields empty. The person needs an Outbind account first: see Create an account.

When the person presses Connect, Outbind opens in the browser. They sign in, pick what the app may do and press Allow:

Read only: read the brain, recall prospects, sort replies.
Can draft and edit: everything above, plus every writing tool, prospect memory, lessons, documents and the email checker. Pick this one for the brain.

They can disconnect any app at any time in Settings, MCP, which ends its access at once.

Claude (web and desktop)

Open Settings, then Connectors, and press Add custom connector. On a Team or Enterprise plan, an owner adds it once under Organization settings, Connectors.
Name it Outbind and paste https://app.outbind.ai/api/mcp. Leave the advanced OAuth fields empty.
Press Add, then Connect. Sign in to Outbind, pick Can draft and edit and press Allow.
In a chat, turn Outbind on in the tools menu and ask, for example: "Write a first email to jane@acme.com."

ChatGPT

Open Settings, then Apps & Connectors, then Advanced settings, and turn on Developer mode. On a Business or Enterprise plan, an admin may need to allow it first.
Back in Apps & Connectors, press Create. Name it Outbind, paste https://app.outbind.ai/api/mcp and pick OAuth for authentication.
Press Create, sign in to Outbind, pick Can draft and edit and press Allow.
In a chat, add Outbind from the + menu.

Claude Code

claude mcp add --transport http outbind https://app.outbind.ai/api/mcp

Then start Claude Code, type /mcp, pick outbind and choose Authenticate. Sign in, pick Can draft and edit and press Allow.

Cursor

Open Cursor Settings, then Tools & MCP, press New MCP server and add this to mcp.json:

{
  "mcpServers": {
    "outbind": { "url": "https://app.outbind.ai/api/mcp" }
  }
}

Next to outbind, press Connect (it may say Needs login), then sign in and press Allow.

VS Code

Add this to .vscode/mcp.json (or run MCP: Add Server, pick HTTP and paste the URL):

{
  "servers": {
    "outbind": { "type": "http", "url": "https://app.outbind.ai/api/mcp" }
  }
}

Press Start above the outbind entry and allow the sign-in.

Other apps

If the app can sign in to MCP servers with OAuth, give it the server URL; it finds Outbind's sign-in by itself (the server answers 401 with a WWW-Authenticate header pointing at its OAuth metadata).

If it only takes a key: in Settings, MCP open Use a key instead, make an AI assistant, can draft and edit key (it is shown once) and send it on every request:

Authorization: Bearer ob_your_key

Keys go in the header only, never in a URL. A key acts as the person who made it, with their current role, and stops working when it's revoked or they leave the workspace.
