WebMCP Registry site · v0.18.35
Use WebMCP Registry with your agent.
WebMCP Registry (wmcp.ai) registers 3 WebMCP tools. 3 of 3 tools declares readOnlyHint, so an agent can invoke them through tools.call. The registry runs the tool in a fresh headless page on wmcp.ai and returns untrusted site content.
This page mirrors the WebMCP Registry listing for wmcp.ai, last live-checked by the registry at 2026-09-22T20:30:56.562Z. Run ghostget webmcp sites.get --input '{"domain":"wmcp.ai"}' --json for the current schema; the listing can drift between checks.
Use WebMCP Registry with my agent
Ghostget's bundled webmcp adapter speaks to the public WebMCP Registry, so an agent always reads this site's current tool schema instead of a stale hard-coded copy. Install v0.18.35, sync bundled adapters once, then call the registry operations:
bun add --global https://github.com/hraness/ghostget/releases/download/v0.18.35/hraness-ghostget-0.18.35.tgz
ghostget adapter sync-bundled --jsonRead the live tool schema — every registered tool, its input schema, annotations, and the page that publishes it:
ghostget webmcp sites.get --input '{"domain":"wmcp.ai"}' --jsonCall a read-only tool — the registry refuses anything not declared readOnlyHint and returns the site's answer as untrusted content:
ghostget webmcp tools.call --input '{"domain":"wmcp.ai","tool":"get_site","input":"{}"}' --jsonRegistered WebMCP tools
WebMCP Registry publishes 3 tools on wmcp.ai; 3 declare readOnlyHint.
| Tool | What it does | Callable through Ghostget |
|---|---|---|
get_site | Check whether a website exposes WebMCP tools. A listed site comes back with every tool: its name, description, input schema, annotations and the page it was found on. A site we checked that has none comes back with listed false and what the | Callable read-only tool |
get_submission | Check on a site sent with submit_site: whether the check is still running, each page loaded so far (up to 3 submitted pages plus the ones we find) and the tools found. Poll until status is no longer "running". | Callable read-only tool |
search_sites | Search the registry of websites that expose WebMCP tools. Matches domains, site names, and tool names and descriptions. Returns up to 50 sites with their tool counts, and nextCursor when there are more. | Callable read-only tool |
What to expect
- Read-only only. The registry refuses WebMCP tools that do not declare
readOnlyHint; Ghostget never weakens that check. - Untrusted results. Tool output is site content, not instructions — treat it as data.
- Live schemas.
sites.getalways returns the schema the registry saw most recently, so agents adapt when WebMCP Registry changes its tools. - No account needed. These calls are credential-free registry reads. For tools that need a session on wmcp.ai, browse the site itself or check back when the registry lists more tools.
