This one needs environment variables set before it will start: AGENT_PAY_BURNER_SEED (32-byte hex secret the per-merchant payer addresses are derived from. Never your owner key.), AGENT_PAY_AGENT_KEY (The budget's agent key (needed when a vault is configured).). The author declared them in the registry entry; get the values from the project itself.

Agent Pay MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Agent Pay MCP?

Agent Pay MCP 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 @deepfirstsearch/agent-pay-mcp was installed 1 532 times last week.

How do I connect Agent Pay MCP?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @deepfirstsearch/agent-pay-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Agent Pay MCP?

The npm package @deepfirstsearch/agent-pay-mcp was installed 1 532 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Agent Pay MCP open source?

Yes — it is published under the MIT licence, written in TypeScript, 1 stars on GitHub and 14 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
