Configuration is passed through the environment: COINCAP_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. It is maintained by wazzan; worth a glance at recent repository activity before you build anything load-bearing on it.
Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
