3 * x402-trinity MCP server - lets an AI agent buy things.

4 *

5 * MCP is how an agent gets tools; x402 is how it pays. This exposes three:

6 *

7 * check_price look at what a resource costs WITHOUT paying

8 * pay_and_fetch fetch it, paying the 402 if it is within your limits

9 * wallet_status address, on-chain balance, what has been spent

10 *

11 * Transport is stdio: newline-delimited JSON-RPC 2.0, per the MCP spec. stdout carries

12 * protocol messages ONLY - every log line goes to stderr, because a stray console.log

13 * on stdout corrupts the stream and the client disconnects.

14 *

15 * ─── THIS SPENDS REAL MONEY ──────────────────────────────────────────────────

16 * A model decides when to call these tools. It cannot be reasoned with about budgets,

17 * and a paywalled page can say anything it likes about its own price. So the limits are

18 * NOT parameters the model can set - they come from the environment, and the server

19 * refuses to start without them:

20 *

21 * X402_PRIVATE_KEY required. Never accepted as a tool argument, never echoed.

22 * X402_MAX_PER_REQUEST required. Atomic units, e.g. 50000 = $0.05.

23 * X402_TOTAL_BUDGET required. The ceiling for this server's whole lifetime.

24 * X402_BUDGET_FILE strongly recommended - survives restarts. Without it the

25 * ceiling resets every time the server is relaunched, which

26 * turns a lifetime cap into a per-session one.

27 * X402_ALLOW_HOSTS optional comma-separated allowlist. With it set, nothing

28 * else can be paid however convincing the 402 looks.

29 * X402_NETWORKS optional, default "base".

30 * X402_ALLOW_ASSETS optional. Defaults to the canonical stablecoin of each enabled

Semantic Analysis Limited

A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review.
