About verify402

verify402 is an MCP server published by the GitHub account a32116150-ctrl. Free x402 preflight gate plus paid on-chain truth checks for AI agents.

It runs on your own machine: your AI client starts it from the npm package verify402-mcp at version 1.0.9.

It asks for one secret: EVM_PRIVATE_KEY. Give it a key with the least access that still works.

Version 1.0.9 was published on 26 October 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.

What it asks for

VariableRequiredSecretDescription
VERIFY402_URLNoNoverify402 base URL
EVM_PRIVATE_KEYNoYesPrivate key for a dedicated hot wallet. Omit for the free preflight_gate only. verify402-mcp@1.0.9 (this published release) defaults paid calls to Base Sepolia testnet (eip155:84532) for the public demo. Base mainnet (eip155:8453) is an explicit opt-in for a separate deployment and is not enabled by this release. Fund only Base Sepolia testnet USDC for the demo. Never use a main wallet.
VERIFY402_NETWORKSNoNoComma-separated EVM payment networks for paid calls. Default Base Sepolia testnet (eip155:84532); set eip155:8453 explicitly for Base mainnet. The supported network-to-canonical-asset map is constrained to Base Sepolia and Base mainnet.
MAX_PAYMENT_USDNoNoHard cap on one x402 payment in USD (default 0.25). Enforced before signing.
MAX_DAILY_USDNoNoOptional cap for total spend per UTC day across restarts.
