WebMCP Registry site · v0.18.35
Use Exa with your agent.
Exa (exa.ai) registers 5 WebMCP tools. 4 of 5 tools declares readOnlyHint, so an agent can invoke them through tools.call. The registry runs the tool in a fresh headless page on exa.ai and returns untrusted site content.
This page mirrors the WebMCP Registry listing for exa.ai, last live-checked by the registry at 2026-09-22T23:21:54.443Z. Run ghostget webmcp sites.get --input '{"domain":"exa.ai"}' --json for the current schema; the listing can drift between checks.
Use Exa 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":"exa.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":"exa.ai","tool":"get_site_overview","input":"{}"}' --jsonRegistered WebMCP tools
Exa publishes 5 tools on exa.ai; 4 declare readOnlyHint.
| Tool | What it does | Callable through Ghostget |
|---|---|---|
get_site_overview | Get an outline of the Exa documentation, grouped by section, with a short description of each page. May be truncated for large sites; use search_docs to find pages not listed. | Callable read-only tool |
navigate_page | Navigate the current browser tab to a Exa documentation page. | Listed for discovery; the registry allows read-only calls only |
read_page | Read the full content of a Exa documentation page as markdown. | Callable read-only tool |
read_skill | Read a Exa agent skill document by name. | Callable read-only tool |
search_docs | Search the Exa documentation for relevant pages and content. | 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 Exa changes its tools. - No account needed. These calls are credential-free registry reads. For tools that need a session on exa.ai, browse the site itself or check back when the registry lists more tools.
