Environment variables to set
BUYER_PRIVATE_KEYSecret0x-hex private key of a dedicated low-value wallet holding USDC on Base. Optional — without it only the free demo_resolve tool is available; with it the paid resolve_entity tool settles $0.005 USDC per call via x402.
ENTITYRESOLVER_URLOverride the service base URL. Defaults to https://entityresolver.xyz.

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
