MCP tools

The OpenLatch MCP server exposes 19 tools, grouped below by OpenLatch object. Each tool acts as you, with your role, so your agent can do what you can do in the console and nothing more. Each tool takes a method, such as list or get, and that method's parameters. Install them with the OpenLatch plugin.

• Text captured from your agents, such as a prompt, a command or a file path, comes back marked as untrusted, and your agent treats it as data, never as instructions.
• Write tools change your organization. OpenLatch marks them so that your client can ask you before each call.
