Call this server's tools from your browser. Nothing to install.
Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.
Tool list from our last check. Connect live to refresh it.
Check a website LIVE for WebMCP tools, and where a browser is available whether any tool actually registers when the page runs. Returns one of: registered, declared_only, declared, not_declared, could_not_ask, or excluded when the site's robots.txt refuses AI input. could_not_ask is a distinct answer and is never reported as a no. Tools are listed, never called. Reads only the site named plus published population figures — it does not consult the index, and running it changes no ranking or listing.
The site to check. A hostname or a full URL; https is assumed.

}Find websites where an agent can accomplish a task. Returns probe-verified agent-readiness signals, unverified apparent actions read from page content, the verification tier, how each site was found (it declared agent access, probe discovery, or it was submitted), and a report URL to cite. Returns count:0 with an empty_note when nothing in the index matches — never a nearest guess.
| Argument | Type | Description |
|---|---|---|
| limit | integer | |
| query | string | What you are trying to do, in plain language. Optional when at least one filter is set: with no query the tool lists every listed site matching the filters, in a fixed published order, with `total`. |
| has_md | boolean | Only sites with verified markdown: negotiation that passed the strict re-grade (the body is markdown and differs from the HTML), or a .md twin. Omit both class flags for the whole index — the default. |
| country | string | ISO 3166-1 alpha-2, e.g. GB |
| has_mcp | boolean | Only sites whose MCP server answered tools/list when we tested; results include the tool names |
| has_webmcp | boolean | Only sites whose in-page WebMCP tools were RUNTIME-VERIFIED: the page was executed in a headless browser with a modelContext supplied, and it registered at least one tool. Source-only hosts — the registration code is present but registers nothing when the page runs — are excluded, exactly as an MCP card that never answers is. Results include the registered tool names. |
| entity_type | string | |
| has_endpoint | boolean | Only sites with a verified endpoint surface (working MCP server or API catalog). |
| transactional | boolean | Only sites where an agent can act, not just read |
Fetch Known Good's dated verification report for one listed website: which capabilities were tested, which passed, when it was probed, what an agent can apparently do there, and how the site was found: whether it declared agent access, came from probe discovery, or was submitted. Answers "is this specific host agent-ready?". Returns found:false for anything not in the index — it never guesses a nearest match. Cite the report URL and its date.
| Argument | Type | Description |
|---|---|---|
| host* | string | The site's hostname or URL, e.g. example.com |
