This one has been quiet for a while

Quiet is not dead — but it is worth knowing when it wakes up, or when someone else takes it over. We watch the repository and tell you either way.

Evidence-backed company facts and current company information for company enrichment and company verification, with field-level sources, freshness and explicit conflicts. Unevidenced fields return UNKNOWN rather than a guess. $0.10 per billable call via x402; a response adding nothing beyond the identifier you supplied is free.

entity_evidence_validate

FREE preflight for entity_evidence: check a request and see the price and guarantees before paying. Retrieves nothing and costs nothing.

MERCATOR Verify — questions

Answers built from our own checks of this server.

What can MERCATOR Verify do?

It exposes 2 tools, read directly from the server on our last check. Among them: entity_evidence, entity_evidence_validate. 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 MERCATOR Verify 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 545 ms. The bar chart above shows every period we have measured.

Is MERCATOR Verify still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect MERCATOR Verify?

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 MERCATOR Verify need an API key?

No. MERCATOR Verify completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is MERCATOR Verify?

It answers our handshake in 545 ms on average, which is faster than 20% 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.
