Install

How do I install the io.github.white-hat-lab/agent-toolkit MCP server?

io.github.white-hat-lab/agent-toolkit runs locally as an npm package, launched with npx -y agent-toolkit-mcp. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 33 exposed · ~2,373 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
