WebMCP Registry site · v0.18.35
Use OutBIG with your agent.
OutBIG (outbig.bid) registers 4 WebMCP tools. 4 of 4 tools declares readOnlyHint, so an agent can invoke them through tools.call. The registry runs the tool in a fresh headless page on outbig.bid and returns untrusted site content.
This page mirrors the WebMCP Registry listing for outbig.bid, last live-checked by the registry at 2026-09-23T02:24:45.949Z. Run ghostget webmcp sites.get --input '{"domain":"outbig.bid"}' --json for the current schema; the listing can drift between checks.
Use OutBIG 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":"outbig.bid"}' --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":"outbig.bid","tool":"compare_outbig_listings","input":"{}"}' --jsonRegistered WebMCP tools
OutBIG publishes 4 tools on outbig.bid; 4 declare readOnlyHint.
| Tool | What it does | Callable through Ghostget |
|---|---|---|
compare_outbig_listings | Read two to five active public OutBIG listings in one call and return the same verifiable fields for each. This does not rank product quality. | Callable read-only tool |
explain_outbig_placement_options | Explain paid listings, free promoted listings, and separate sponsor ads using OutBIG's current read-only stats and shared pricing rules. This never starts checkout or reserves a place. | Callable read-only tool |
get_outbig_listing | Read one active public OutBIG listing by identity key, domain, repository path, or @handle, including placement and ranks. | Callable read-only tool |
search_outbig_listings | Search or list active public OutBIG marketplace listings through the existing read-only API. Rank is paid placement, not a quality score. | 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 OutBIG changes its tools. - No account needed. These calls are credential-free registry reads. For tools that need a session on outbig.bid, browse the site itself or check back when the registry lists more tools.
