List the available tools (briefs only). Optionally filter by a free-text string and/or a category. Returns [{ name, summary, category }]. Call toolfunnel_tool_instructions for a specific tool, then run it yourself per its instructions.

Get the full usage instructions / documentation for one tool by name (venv, the reliable invoke command, safety notes). Read this before running the tool yourself.

Execute one register tool by its name through the gateway PreToolUse gate. Args: { name, args? }. Call toolfunnel_tool_instructions first to learn the tool's arg shape. Returns { ok, output, error? }. Every call is gated (a PreToolUse hook may deny it).

Get self-extension instructions: how to author a new tool, register an upstream MCP, add a hook, or build a shareable package. The system documents how to extend itself.
