How to connect an MCP server
1
Open the Integrations tab
Navigate to MSP Settings → Integrations.
2
Add an MCP server
Click the Add MCP Server button in the top-right corner of the page.
3
Enter the server URL
Paste the full URL of your MCP server endpoint (e.g.
https://tools.yourcompany.com/mcp).4
Complete authentication
Rallied probes the server to detect what authentication it requires:
- OAuth
- Bearer token
- No authentication
If the server uses OAuth, you are redirected to an authorization flow. Complete the authorization in your browser. The token is stored securely and passed to the server at runtime.

Tools are synced automatically
Rallied fetches the tool list from your MCP server and adds all discovered tools to the agent’s catalog. Default policies are seeded automatically based on each tool’s name and description. The server shows as connected and the agent can start using the tools immediately.

Managing tools from MCP servers
Tools from custom MCP servers appear in the agent’s tool catalog alongside built-in integration tools. You manage their policies the same way:- Open the MCP server’s detail page from MSP Settings → Integrations
- Find the tool by name (MCP tools are prefixed with
mcp:<server-name>:) - Set the permission to Auto, Approval needed, or Disabled
You can override any of these defaults.
