Implementation Reference
- tools/cache_tool.py:5-18 (handler)The async function that executes the cache_info tool logic: if clear=True clears the cache, otherwise returns cache statistics as JSON.
async def cache_info(clear: bool = False) -> str: """ Shows cache statistics or clears the cache. Args: clear: True — clears the cache, False — shows statistics. Returns: JSON with cache stats or clear result. """ if clear: removed = cache.clear() return json.dumps({"cleared": True, "removed_entries": removed}, ensure_ascii=False, indent=2) return json.dumps(cache.stats(), ensure_ascii=False, indent=2) - tools/cache_tool.py:5-18 (schema)The function signature defines the input schema (optional clear: bool = False) and output type (str).
async def cache_info(clear: bool = False) -> str: """ Shows cache statistics or clears the cache. Args: clear: True — clears the cache, False — shows statistics. Returns: JSON with cache stats or clear result. """ if clear: removed = cache.clear() return json.dumps({"cleared": True, "removed_entries": removed}, ensure_ascii=False, indent=2) return json.dumps(cache.stats(), ensure_ascii=False, indent=2) - server.py:35-35 (registration)Registration of cache_info as an MCP tool on the FastMCP server via mcp.tool()(cache_info).
mcp.tool()(cache_info) - tools/__init__.py:6-12 (registration)Re-export of cache_info from tools/__init__.py so it can be imported by server.py.
