@getplexa/mcp — Plexa MCP server

A Model Context Protocol server that gives any MCP client (Claude Desktop, Cursor, your own agent) two economic-safety tools from [Plexa](https://getplexa.com) — the x402-native economic-safety layer for trading agents — paid per call in USDC, no accounts:

| Tool | Wraps | Price | Returns | |---|---|---|---| | plexa_quote | POST /v1/quote | $0.02 | Executable fill price under size (not mid/spot), price impact (bps), realizable depth, per-leg route, worst-case slippage, confidence — from canonical on-chain quoters on Base, Polygon & Arbitrum. | | plexa_pretrade_check | POST /v1/pretrade/check | $0.05 | Two levels. `verdict`: avoid only when a listed trap is *proven* on-chain at that block (no pool to exit into · the counter-asset pot is under 5% of your size, and the pot is a hard upper bound on what a sale can return · the token's own trading gate is off), clear otherwise — clear means *no provable trap*, not "safe". `risk_profile`: age, holder concentration, liquidity depth incl. exitLiquidityUsd, oracle availability, transfer limits — as data you weigh, not as a rating. Plus reasons, confidence and an executable quote. (Base-only today.) |

It is a thin client of the public API (https://api.getplexa.com) — it pays a 402 automatically, signs the USDC authorization locally with your wallet, and never sees your key. The liquidity engine stays behind the API.

Why

A generic wallet guard answers *"can I sign this transaction?"*. It can't answer the economic question an automated trader actually needs: *what price will this swap really fill at under my size, and is this token a trap (rug / honeypot / thin liquidity)?* Plexa answers both. This package puts those answers one tool-call away inside any MCP-speaking agent.

Install

Nothing to install — point your MCP client at the package via npx. It is fetched and run on demand.
