Browse the MCP tools without an API key
List all 16 MCP tools, with their input schemas and their annotations, before signing in.
katto-mcp 0.5.4 lists the tools before authentication, with each input schema and each annotation: whether a tool only reads, whether it destroys something, whether calling it twice is the same as calling it once.
That last one matters more than it sounds. Re-rendering and dubbing are marked as not idempotent, because each call produces a new render and bills for it. An agent that assumes otherwise will spend your quota twice.
Listed on the official Model Context Protocol registry, mcp.so, Smithery and Glama.
