No usage claims. Nobody has run this tool. The other tier is BENCH-TESTED, which means Andrew personally ran the tool on a stated date and cannot be bought at any price.

The other 600 are unmeasured, which is not the same as empty. Harvest last run 2026-09-27. Every name across every server is on the [tools index](../tools-index.md). **Command line** No CLI found by the 2026-09-27 harvest across vendor docs, npm, PyPI, Homebrew and GitHub. That is a probe result, not proof of absence. **Access gate** - **Gate bucket**: Gate unknown - **Can a solo operator reach it**: Not established api_gate, verbatim from the file: unknown 949 of 1252 entries carry an unknown gate. Unknown is a legal answer and it ships as unknown rather than as a guess. **API documentation** No documentation URL recorded. 727 of 1252 entries are in the same position. Blank is legal and it is published as blank. **GitHub health** Not measured. github_url, github_stars, github_last_commit and github_archived are null on every entry in this build. The refresh rail specced in SPEC section 7.2 has not been run. An unstamped star count is a lie, so nothing is shown rather than something stale. **On GitHub** No GitHub organisation could be tied to mcp.datamerge.ai with evidence on 2026-09-15. Recorded by the harvest: not checked: gh CLI missing or not logged in. **Jobs it can do** No job tag on this entry. 981 of 1,252 entries are untagged. An empty list here means nobody has tagged this, not that the tool does nothing. The vocabulary is closed, so a tool whose job is genuinely not in it stays blank rather than being forced into the nearest tag. **Sources** - [https://mcp.datamerge.ai](https://mcp.datamerge.ai) 1 source URL. Thin. The standing rule is at least two independent sources with the vendor's own site unable to be both of them, and this entry does not meet it. 100 entries are in the same state and they are listed on the methodology page. Raw sources field, verbatim: https://mcp.datamerge.ai **Notes, verbatim from the file** Homepage fetch failed (HTTPError 400); what_it_does used staging desc. mcp_status=community from official-mcp-registry listing; not an invented official vendor MCP. mcp_url is the registry/listing or product MCP URL from staging. api_gate unknown with dated probe 2026-09-12; free/paid not inferred from HTTP status alone.
