Connect external tools

When do you need MCP?#

MCP connects external service tools to Mirr Code. For example, you might read issues from a tracker or use material from a design tool. Ordinary coding work that does not need external services requires no extra connection.

Prepare the service#

Find the address and sign-in instructions in the service's official MCP guide. You may need an account and access to that service. Some connections need only an address; others need another program installed or a separate sign-in.

Do not enter an arbitrary address or run installation commands from an unknown publisher.

Connect using an address#

Enter /mcp inside Mirr Code to open tool management. For a service that connects through an address, add it using this format:

/mcp add my-service --http https://example.com/mcp

This is a format example, not a working service. Replace my-service with a recognizable name and the URL with the actual MCP address from the service's official guide. For a tool supplied as a local program, follow its publisher's installation instructions.

If sign-in is required, select the service in /mcp and follow the authentication instructions. For API-key services, use the secure storage method recommended by the service; do not paste keys into conversations or project files.

Use the connection#

Open /mcp to inspect connection status and available tools. If you used the example connection name, /mcp tools my-service shows its tools.

If the connected service supports issue lookup, you can ask: “Show my unfinished assigned issues from this service.” What you can do depends on the tools the service actually provides.

Adding tools does not change the model. Execution is affected by Work modes and Tools and permissions. Do not grant write access to a service account when your work only requires reading.

Disconnect and troubleshoot#

Remove an unused connection with /mcp remove my-service, replacing the name with your actual connection name. To revoke access granted to the service account, manage connected apps or tokens in the service as well.

If tools are missing, check the status and error in /mcp. Compare address errors with the official connection guide. For sign-in failures, authenticate again with the service. If the connection requires a local program, check that it is installed.
