Agent Master Data — questions

Answers built from our own checks of this server.

What can Agent Master Data do?

It exposes 7 tools, read directly from the server on our last check. Among them: assess_master_data_quality, get_master_data_golden_record, get_master_data_relationships, get_master_data_schema, get_reference_data, resolve_master_data_entity 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 →

Is Agent Master Data working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 79 of 92 checks got a reply (85.9%), average response time 118 ms. The bar chart above shows every period we have measured.

How do I connect Agent Master Data?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Agent Master Data need an API key?

No. Agent Master Data 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 Agent Master Data?

It answers our handshake in 118 ms on average, which is faster than 89% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
