Wedges

The agent edition of Both Hands Full.

Both Hands Full is a set of exercises that help humans protect their taste, voice, and judgment in the age of synthetic everything. Wedges is the inversion: point your agent at the same exercises and walk away with a portable taste profile — a style guide, worldview, glossary, voice patterns, and irreducible list — that any agent can load to serve your work without flattening it.

It's a public, no-auth remote MCP server. Connect Claude Code, Codex, ChatGPT, Cursor — same URL.

Hold critique in one hand. Hold curiosity in the other. Keep walking.

Connect

Claude Code:

claude mcp add --transport http wedges https://wedges.dev/api/mcp

Any client (.mcp.json / config):

{
  "mcpServers": {
    "wedges": { "type": "http", "url": "https://wedges.dev/api/mcp" }
  }
}

Then, in a session: "Run the Wedges taste extraction." The agent self-drives via the start_wedges prompt.

Keys & privacy

• The LLM tools use the server's ANTHROPIC_API_KEY by default. To use your own, pass anthropic_api_key as a tool argument.
• Nothing is stored. Profiles are handed back to your agent and forgotten. No accounts, no database, no auth.
• The two LLM tools (mirror_booth, taste_audit) are rate-limited — ~10/min per IP on the shared server key, ~60/min when you bring your own. The deterministic tools are unthrottled. (The limiter is in-memory/per-instance — a v1 guardrail; see lib/rate-limit.ts.)

Develop

npm install
npm run dev          # http://localhost:3000/api/mcp
npm run verify       # typecheck + the MCP smoke test (needs the dev server running)

The exercise logic is ported from the Both Hands Full app; see lib/. The MCP server is one route: app/api/[transport]/route.ts.
