Blue Cap Machine Commerce — questions

Answers built from our own checks of this server.

What can Blue Cap Machine Commerce do?

It exposes 7 tools, read directly from the server on our last check. Among them: agent_wallet, evidence_verify, evidence_verify_mpp, hash_compute, hash_compute_mpp, schema_validate and 1 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 Blue Cap Machine Commerce mostly used for?

Its tools cluster around evidence, hash and schema. 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 Blue Cap Machine Commerce working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 537 ms. The bar chart above shows every period we have measured.

How do I connect Blue Cap Machine Commerce?

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 Blue Cap Machine Commerce need an API key?

No. Blue Cap Machine Commerce completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Blue Cap Machine Commerce?

It answers our handshake in 537 ms on average, which is faster than 21% 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.
