About halowerk-mcp

halowerk-mcp is an MCP server published by the GitHub account halowerk. 134 paid APIs as MCP tools, billed per call in USDC on Base. No account, no login.

It runs on your own machine: your AI client starts it from the npm package halowerk-mcp at version 0.1.1.

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

Version 0.1.1 was published on 12 August 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.
