About tool-filter-mcp

tool-filter-mcp MCP proxy server that filters tools from upstream MCP servers via regex-based deny list. Maintained: ✅ Yes (Spring/summer 26) Why use this? For effective context engineering, we want to minimize useless tokens. Most major agents right now (e.g. Claude Code) do NOT remove tool descriptions from the context. Even though the tool is completely denied and unused, the model will still get its entire description and still try to call the tool (and get error messages).
