Seamless.AI

The vendor ships and maintains the server itself. A wrapper built by Zapier, Composio or a similar third party does not count as official. The status was established by hand on 2026-09-07. On 2026-09-04 the recorded URL served a documentation page, not an MCP endpoint. That is where to read about the server, not where to connect to it. An agent needs the second.

A tool below is one the server NAMES. Nobody has called it. That is the same two tier honesty rule the rest of the directory runs on: a named tool is research, and BENCH-TESTED stays the only claim that anybody ran anything.

141 of the 741 entries that record an official or community MCP server carry a harvested tool list. 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.

This is a third party's CLI. It was published by somebody other than the vendor, so it is that author's surface for the vendor's API and not the vendor's published surface. The two must not be read as the same thing.

Install, as the source shows it:

npm install -g seamless-ai-cli

quoted from https://www.npmjs.com/package/seamless-ai-cli on 2026-09-27, via npm, a third party source

Packages seen, with the version on 2026-09-27:

• npm: seamless-ai-cli 0.1.8, third party

A CLI being listed means the harvest found an install command or a package on a stated date. Nobody has run it. Every command is quoted verbatim from the URL beneath it. Harvest date 2026-09-27.

enterprise-only

No documentation URL recorded.

727 of 1252 entries are in the same position. Blank is legal and it is published as blank.

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.

No GitHub organisation could be tied to seamless.ai with evidence on 2026-09-08.

Recorded by the harvest: github candidates were seen but none passed the evidence rules.

5 candidate accounts seen and rejected by the evidence rules: seamless-protocol, modelcontextprotocol, SeamlessAI, chainflip-io, seamless-test. A name match alone is never accepted; the account has to point at the vendor domain.

• Search people by criteria
• Search companies by firmographics
• Build a target account list
• Find a work email address
• Find a phone number
• Research an account before a call
• Run an email sequence

A job tag means the vendor says the tool does this. It is not a test result, not proof the capability is reachable through the tool's MCP server, and not proof it is available on the gate this entry records.

Tagged by machine-pass on 2026-08-25 against the closed 56 job vocabulary. 271 of 1,252 entries carry at least one tag; 849 tags are assigned in total.
