# Yaak MCP Server Plugin Exposes Yaak's functionality via the [Model Context Protocol (MCP)](https://modelcontextprotocol.io/). ## Setup Add this to your Claude Desktop config (`~/Library/Application Support/Claude/claude_desktop_config.json` on macOS): ```json { "mcpServers": { "yaak": { "command": "npx", "args": ["-y", "mcp-remote", "http://127.0.0.1:64343/mcp"] } } } ``` Restart Claude Desktop and make sure Yaak is running. ## Available Tools - `list_http_requests` - List all HTTP requests in a workspace - `get_http_request` - Get details of a specific HTTP request - `send_http_request` - Send an HTTP request and get the response - `create_http_request` - Create a new HTTP request - `update_http_request` - Update an existing HTTP request - `delete_http_request` - Delete an HTTP request - `list_folders` - List all folders in a workspace - `list_workspaces` - List all open workspaces - `get_workspace_id` - Get the current workspace ID - `get_environment_id` - Get the current environment ID - `copy_to_clipboard` - Copy text to the system clipboard - `show_toast` - Show a toast notification in Yaak ## Environment Selection `send_http_request` accepts an optional `environmentId` for that execution. It overrides the active environment without changing the selection in Yaak. Omitting it uses the host's active environment, as before. The ID must identify a base or sub-environment in the request's workspace. An empty, unknown, foreign-workspace, or folder environment ID returns an error before sending. Use the base environment ID to run with global variables only. Folder variables still apply according to the request's folder hierarchy. ```json { "id": "rq_example", "workspaceId": "wk_example", "environmentId": "ev_staging" } ``` This requires a Yaak host with support for the `environmentId` plugin API field; older hosts ignore it. `get_environment_id` reports the active selection, not the override used by a previous send.
