# Snap Router — MCP server

<!-- mcp-name: io.github.trigeochiral/snap-router -->

Task-to-tool discovery for AI agents, pay-per-call in USDC on Base (x402), free tier, no signup.

Hosted API: `https://trigeochiral.com` — set it as `SNAP_API`.

## Tool

| Tool | What |
|---|---|
| `snap_router` | Your task → the ranked x402 / MCP tools that serve it, over the merged x402 Bazaar + MCP Registry catalog (16k+). One pass, ~200ms, no LLM call. $0.003 |

## Why

Past ~2,000 tools, semantic retrieval beats keyword and beats long-context. Coinbase's Bazaar
`/ask` is LLM-ranked (a model call on every task); 402index falls back to keyword-only when its
embedding service times out. Snap Router has neither hole.

## Install

```bash
pip install snap-router-mcp
claude mcp add snap-router --env SNAP_API=https://trigeochiral.com -- snap-router-mcp
```

or with `uvx` (no install):

```bash
claude mcp add snap-router --env SNAP_API=https://trigeochiral.com -- uvx snap-router-mcp
```

Optional: `SNAP_XPAYMENT` = a base64 x402 `X-PAYMENT` payload, to make paid calls past the free
tier. Without it you get 25 free calls/day per IP.

## Direct HTTP (no MCP)

```bash
curl -sX POST https://trigeochiral.com/v1/snap -H 'content-type: application/json' \
  -d '{"task":"check a base token for honeypot before trading","k":4}'
```
