This one needs environment variables set before it will start: AE_API_KEY (Vault-issued API key. Required only for the vault-governed tools (ae_get_agent, ae_verify_action, ae_mint). Sovereign verification needs no key.). The author declared them in the registry entry; get the values from the project itself.

Agent Envelope MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Agent Envelope MCP?

Agent Envelope 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 agent-envelope-mcp was installed 110 times last week.

How do I connect Agent Envelope 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 agent-envelope-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Agent Envelope MCP?

The npm package agent-envelope-mcp was installed 110 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 Envelope MCP open source?

Yes — it is published under the Apache-2.0 licence, written in JavaScript and 1 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
