MCP Connection

Use this skill for organization-scoped MCP server registration, OAuth or bearer-token authentication, tool discovery, and MCP tool calls from Backoffice runtimes.

MCP configuration

The MCP capability is available automatically for the current scope.

• Register each remote MCP server with a stable lowercase slug, a display name, the streamable HTTP endpoint URL, and an auth mode.
• For OAuth servers, create the server first with auth: { type: "oauth" }, then start OAuth and send the returned authorizationUrl to the user.
• For bearer-token servers, create the server with auth: { type: "bearer", token } or set the token after creation.

OAuth setup example:

const serverId = "cloudflare-mcp";

await mcp.createServer({
  slug: serverId,
  name: "Cloudflare MCP",
  endpointUrl: "https://mcp.cloudflare.com/mcp",
  auth: { type: "oauth" },
});

const auth = await mcp.startOAuth({ slug: serverId });
return auth.authorizationUrl;

After the user completes OAuth, refresh the server tools with mcp.refreshServer({ slug: serverId }).

MCP events

Cataloged automation events:

• source: mcp, eventType: server.configuration.changed — fires after a server refresh when the advertised tools differ from the previous cache.
• source: mcp, eventType: server.configuration.deleted — fires after an MCP server configuration is deleted.

Treat MCP as a tool-backed capability: automations register servers, refresh advertised tool caches, and call those tools when an external MCP service is needed.

MCP tools

MCP tools can:

• list configured MCP servers;
• register and delete remote streamable HTTP MCP servers;
• start OAuth login for a server;
• store bearer tokens;
• refresh the cached tools advertised by a configured server;
• call tools exposed by a configured server.

Use the declared mcp provider methods: listServers, createServer, deleteServer, refreshServer, startOAuth, setToken, and callTool.

Examples:

await mcp.listServers();
await mcp.refreshServer({ slug: "cloudflare-mcp" });
await mcp.callTool({
  slug: "cloudflare-mcp",
  name: "docs",
  arguments: { query: "Durable Objects alarms" },
});
