Connect
## Pick your client.
Server URL: `https://api.askravn.com/mcp`

- / 01
### Claude (web, desktop, mobile)
Settings → Connectors → Add custom connector → paste the URL → sign in with your email code → Allow.

- / 02
### Claude Code
`claude mcp add --transport http ravn https://api.askravn.com/mcp`, then run `/mcp` and choose Authenticate.

- / 03
### Cursor, Windsurf and other clients
Add the URL as a remote server. Clients that support MCP OAuth open the same sign-in page; others take an `Authorization: Bearer` header.

- / 04
### Servers and CI
Use an API key header instead of OAuth: `--header "Authorization: Bearer $RAVN_API_KEY"`.

Security
## OAuth done properly.
Standard MCP authorization: discovery documents, dynamic client registration, PKCE and short-lived tokens. You can revoke access any time.

- / 01
### No password, no pasted key
You sign in with a one-time email code. The consent page shows exactly where it will send you back.

- / 02
### Short-lived tokens
Access tokens last an hour. Refresh tokens rotate, and reusing an old one cuts off the whole session.

## The tools Claude gets.
Email, finding, website and IP tools run on our own tech; people, company and carrier tools run on your own provider key. Every tool is one lookup, and a miss is free.

FAQ
## MCP questions.

Does it work on Claude.ai free plans?Custom connectors depend on your Claude plan. If your plan supports custom connectors, Ravn works there.
Is it a local or remote server?Remote. Nothing to install or keep running; Claude talks to `https://api.askravn.com/mcp` directly.
Can my agent set itself up?Point it at [llms.txt](https://askravn.com/llms.txt). A person still has to receive the sign-in code once.
How do I disconnect?Remove the connector in your client. Its tokens stop working within the hour, or straight away if the client revokes them.
