Implementation Reference
- mu_mcp/mu_mcp.py:48-68 (handler)The main handler function for the 'view' tool. Takes paths as input, runs 'mu view' subprocess command, and returns the email content or error message.
def view(paths: str) -> str: """View emails using `mu`, by providing their paths. ``` mu view $paths ``` Paths can be extracted using the following: ``` mu find --fields "l" SOME_QUERY ``` """ import subprocess try: result = subprocess.run( ["mu", "view"] + paths.split(), capture_output=True, text=True, check=True ) return result.stdout.strip() except subprocess.CalledProcessError as e: return f"Error: {e.stderr.strip()}" - mu_mcp/mu_mcp.py:47-59 (schema)The function signature and docstring define the input schema (paths: str) and output schema (str). The docstring documents the tool's purpose, usage syntax, and how to obtain paths for the tool.
