X402 Trinity MCP Server

X402 Trinity is an MCP integration. Give an agent a wallet. Pays for x402 resources within hard limits. Base + USDC, gasless.

Packages and local setup

The published npm package is x402-trinity, version 0.2.4. Its declared MCP transport is stdio.

The package declares X402_PRIVATE_KEY (required): Private key of the wallet that pays. Use a dedicated wallet holding only what you would accept losing. The server refuses to start without it.; X402_MAX_PER_REQUEST (required): Hard ceiling for a single payment, in atomic units (USDC has 6 decimals, so 50000 is $0.05). Required: a model decides when payments happen, so the cap cannot come from the model.; X402_TOTAL_BUDGET (required): Lifetime ceiling across all payments, in atomic units. Required for the same reason as the per-request cap.; X402_BUDGET_FILE: Path to a file that makes the lifetime budget survive restarts. Without it the total resets every time the server starts.; X402_ALLOW_HOSTS: Comma-separated hosts that may be paid. Anything else is refused however convincing the challenge looks.; X402_NETWORKS: Networks to accept. Defaults to base..
