Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

NameDescription
ORCPIN_PRIVATE_KEY
Required, secret		Private key (0x + 64 hex) of a dedicated, low-balance Base wallet holding a few dollars of USDC. Used only to sign gasless x402 payment authorizations; never transmitted. A door report costs about $50, so fund for what you intend to buy.
ORCPIN_TOOLSETS
Optional		Optional comma-separated subset of tools to expose: "defi" (chain + endpoint-reliability tools) and/or "trading" (trade-log calculators). Default: all ten paid tools. The free directory tool is always exposed; the ledger tools (statement, door report) are exposed regardless of this setting.
X402_NETWORK
Optional		x402 network id. Default eip155:8453 (Base mainnet).
