About ToolCall

A curated discovery destination for AI agent tools.

ToolCall is a deliberately small, hand-edited catalog of MCP servers, Claude Skills, plugins, browser extensions, CLIs, and Savants. It sits on top of the existing ecosystem — the MCP Registry, Smithery, the Anthropic plugin marketplace — and layers curation, taste, and real security vetting on top of those raw pools.

Our home is Sudio 404: a fictional converted industrial warehouse run by three young hackers — Sudo (has all the permissions), Grep (finds everything), and Curl (has zero curls). Every tool you see here has been picked by one of them.

Three pillars

  1. Curation. Every tool is hand-picked with a one-paragraph editorial pitch. We say no often.
  2. Security. The Lossy Channel pipeline vets Tier 2 and Tier 3 tools — real architectural defense against prompt injection, beyond what registries offer today.
  3. Voice. Sudio 404 + the crew + an underground hack-lab aesthetic. The voice is the moat. No corporate marketplace will commit to a real point of view.

What this isn't

Not a registry. Not a gateway. Not a hosting provider. Not comprehensive. Not corporate.

Status

This is v0.1 — the warehouse just opened its doors. The catalog is small on purpose; it will grow.
