Get an MCP key
MCP uses its own key namespace, separate from yourorb_ router keys.
1
Create the key
On the dashboard’s Customise page, create an MCP key. It looks like
mcp_a1b2c3d4_… and is shown once.2
Authenticate
Send it as
Authorization: Bearer mcp_… (or ?key=mcp_… for clients that can’t set headers).An MCP key can only call
/api/mcp — it cannot make LLM calls. An orb_ key cannot call /api/mcp. Revoking is immediate with no un-revoke; mint a new key to restore access.Client setup
- Claude Desktop
- VS Code
- Cursor
SSE transport via Claude Desktop can also auto-mint a key via the built-in OAuth flow (the server implements OAuth 2.0 authorization-server metadata, dynamic client registration, token, and revoke), so
mcp-remote. Add to claude_desktop_config.json:mcp-remote can authenticate without a pasted key.
