WebMCP Registry site · v0.18.35
Use Top Five with your agent.
Top Five (mytopfive.app) registers 3 WebMCP tools. 2 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 mytopfive.app and returns untrusted site content.
This page mirrors the WebMCP Registry listing for mytopfive.app, last live-checked by the registry at 2026-09-23T00:40:55.980Z. Run ghostget webmcp sites.get --input '{"domain":"mytopfive.app"}' --json for the current schema; the listing can drift between checks.
Use Top Five 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":"mytopfive.app"}' --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":"mytopfive.app","tool":"get_my_profile","input":"{}"}' --jsonRegistered WebMCP tools
Top Five publishes 3 tools on mytopfive.app; 2 declare readOnlyHint.
| Tool | What it does | Callable through Ghostget |
|---|---|---|
get_my_profile | The profile of whoever is signed in on this page — username, display name, bio and avatar. Reads the session out of the page, so it answers for the actual viewer and needs no user id passed in. If nobody is signed in, it fails with a missin | Callable read-only tool |
search_public_lists | Search public Top Five lists by keyword and return each match with its creator, description and a link. Replays the same query the Discover screen runs, so the results are exactly the lists that screen would show for the same words. Matchin | Callable read-only tool |
set_my_display_name | Rename the signed-in user — the name shown on their profile and beside every list they have made. Writes only the viewer's own row; Row Level Security rejects anything else, so this cannot rename another account even if asked to. Succeeds w | Listed for discovery; the registry allows read-only calls only |
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 Top Five changes its tools. - No account needed. These calls are credential-free registry reads. For tools that need a session on mytopfive.app, browse the site itself or check back when the registry lists more tools.
