agentmods-mcp

An MCP server for agentmods.dev — a catalogue of 648,000+ mods for coding agents (skills, subagents, slash commands, hooks, MCP servers, Cursor rules, instructions files) where every entry is measured: token cost per session, a security scan with the evidence line for each finding, original vs copy, and what changed since last week.

Plug it into Claude Desktop, Claude Code, or any MCP client, and the model can search the catalogue and choose by the measurements — not by vibes.

Setup

.mcp.json (project) or your client's MCP config:

{
  "mcpServers": {
    "agentmods": { "command": "npx", "args": ["-y", "agentmods-mcp"] }
  }
}

Zero dependencies, Node >= 18, stdio transport.

Tools

• search_mods { query, type?, limit? } — names ("playwright") and plain intent ("make my agent cheaper") both work; every result carries tokens_per_session, security_grade, origin, repo_stars and the install command.
• mod_info { slug } — one mod's full detail: measurements, licence, files, and per-agent install commands (Claude Code, Codex, Gemini CLI, Cursor, GitHub Copilot).

Agents with a shell can skip MCP entirely: the agentmods CLI searches and installs directly (npx agentmods add <slug>), and this server ships inside it too (npx agentmods mcp).
