Keystone Claude Connector

Adding the Keystone MCP server to Claude as a custom connector, for an organization or for one account.

Reviewed Oct 10, 2026

Claude connects to the Keystone MCP server as a custom connector. Nothing about the server is specific to Claude (Connecting an MCP client is the general case); this page is the Claude-side setup.

For an organization

  1. An organization owner opens Organization settings → Connectors and chooses Add custom connector.
  2. Name it Keystone and enter the URL https://mcp.keystone.app/mcp. Leave the OAuth client fields empty; Claude discovers the authorization server from the URL.
  3. Save. The connector appears for members; each member connects it from their own settings and signs in to Keystone once.

For one account

In Settings → Connectors, add a custom connector with the same URL, then Connect and sign in to Keystone.

Using it

In a conversation, enable the Keystone connector and ask for a business by name, website, or domain. Claude calls find_business; the picker card lists the matches. Click one to open a session. From there Claude reads the business and proposes changes; you review them on the card and apply with a click. How a session works walks the whole sequence, and the tool reference lists what Claude can and cannot call.
