⚠️ DEPRECATED — DO NOT USE
v0.1.7 ships with a default HASHLOCK_ENDPOINT of https://hashlock.markets/api/graphql — the browser-only cookie proxy. External MCP clients (Claude Desktop, Cursor, Windsurf, Raycast) cannot authenticate against it because they do not maintain cookies, so every Bearer-authenticated call returns 401 Unauthorized - missing api-token.
Use v0.1.8 instead. The npm tarball for v0.1.7 has been deprecated (npm view @hashlock-tech/mcp@0.1.7 deprecated).
