Exa

A live handshake means the URL answered an MCP initialize as a server on the probe date. It is liveness and nothing more: nobody has run its tools. A tool being catalogued means a server names it, by answering tools/list, in its own source, or in the vendor's documentation. None of them has been called. A tool count of 0 means not measured, never zero tools.

Exa

A search API that returns web pages and structured results ranked by semantic/meaning similarity to a query (embeddings-based) rather than keyword matching, plus tools to fetch page contents and get LLM-generated answers with citations; used in GTM stacks...

1 of 1 free to start, a solo operator gets API access without talking to anyone.

The gate is the api_gate field on each product entry, established by hand on the last_checked date shown above. It records whether a solo operator can get API access without a contract. Money is not tracked.

• Scrape a web page for facts
• Research an account before a call

2 distinct job labels, the union across 1 product, tagged 2026-08-25. 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.

• https://github.com/exa-labs/exa-mcp-server (Exa, docs page, probed 2026-09-04)

An endpoint is where an agent connects. A docs page is where a person reads about connecting. Both are published because both are what the probe found; an agent needs the first.

Exa exa-cli community CLI

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.

pip install exa-cli

quoted from https://pypi.org/project/exa-cli/ on 2026-09-27, via pypi, a third party source

harvested 2026-09-27, all on the tool page.

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.

github.com/exa-labs tied to the vendor by rule 1, account website https://exa.ai has the vendor's domain, confidence strong

Kind is a heuristic guessed from the repository name, topics and description, not a fact the vendor stated. A repository count is activity, not a verdict. Read 2026-09-08.

A job tag is a vendor claim: it means the vendor says the product does this, and it is not a test result. A listed tool has not been run: the catalogue says what an agent could try, not what works. 1 of 1,252 directory entries are bench tested, meaning somebody personally ran the tool on a stated date, and 1 of this vendor's 1 product is among them. There is no verdict here on whether this vendor is better than another.

Vendor pages group the directory's canonical product entries by vendor_domain. The vendor name is the product display name that matches the domain when several products share it; nothing on this page is typed by hand. Data baked 2026-09-27 by build_directory.py (phase 1).
