Today is the operative word: we check Entity-ID Resolver every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

Optional settings from the registry entry, left out of the block above: BUYER_PRIVATE_KEY (0x-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_URL (Override the service base URL. Defaults to https://entityresolver.xyz).

Entity-ID Resolver — questions

Answers built from our own checks of this server.

Why is there no uptime for Entity-ID Resolver?

Entity-ID Resolver runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package entityresolver-mcp was installed 67 times last week.

How do I connect Entity-ID Resolver?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls entityresolver-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Entity-ID Resolver?

The npm package entityresolver-mcp was installed 67 times in the last week. Week over week that is +23%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
