Hex.pm MCP — questions

Answers built from our own checks of this server.

What can Hex.pm MCP do?
It exposes 24 tools, read directly from the server on our last check. Among them: alternatives, audit, audit_mix_deps, compare, dependencies, dep_tree and 18 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
What is Hex.pm MCP mostly used for?
Its tools cluster around toolbox, docs and audit. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is Hex.pm MCP working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 784 ms. The bar chart above shows every period we have measured.
How do I connect Hex.pm 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 is a remote server, so there is nothing to install — the client connects to the address.
Does Hex.pm MCP need an API key?
No. Hex.pm MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 24 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Hex.pm MCP?
It answers our handshake in 784 ms on average, which is faster than 10% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Hex.pm MCP open source?
Yes — it is published under the MIT licence, written in Elixir and 2 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.
