WebMCP Registry site · v0.18.35
Use Fever with your agent.
Fever (feverup.com) registers 9 WebMCP tools. 6 of 9 tools declares readOnlyHint, so an agent can invoke them through tools.call. The registry runs the tool in a fresh headless page on feverup.com and returns untrusted site content.
This page mirrors the WebMCP Registry listing for feverup.com, last live-checked by the registry at 2026-09-23T06:12:58.689Z. Run ghostget webmcp sites.get --input '{"domain":"feverup.com"}' --json for the current schema; the listing can drift between checks.
Use Fever 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 --json
Read the live tool schema — every registered tool, its input schema, annotations, and the page that publishes it:
ghostget webmcp sites.get --input '{"domain":"feverup.com"}' --json
Call 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":"feverup.com","tool":"feed_get_page_context","input":"{}"}' --json

Fever publishes 9 tools on feverup.com; 6 declare readOnlyHint.
| Tool | What it does | Callable through Ghostget |
|---|---|---|
feed_get_page_context | Returns the current city feed context: city name, language, all carousel sections (id, title, slug, plan count, category URL), and total plan count across all carousels. Call this first to understand what is available on the feed. | Callable read-only tool |
feed_get_plans | Returns plans from the feed. If carouselSlug is provided, returns plans from that carousel only. If omitted, returns plans from all carousels. Get valid slugs from feed_get_page_context. | Callable read-only tool |
feed_get_top_plans | Returns all plans from the first carousel on the feed, which is always the curated top-N list for the city (e.g. "Top 10 in Madrid"). Requires no input. | Callable read-only tool |
home_list_cities | Returns the list of top cities available on Fever, each with its name, slug, country, and direct feed URL. Call this to discover which cities a user can navigate to. | Callable read-only tool |
home_navigate_to_city | Navigates the browser to the event feed for the given city slug. Use slugs returned by home_list_cities. Navigation is blocked if the target URL leaves the current domain. | Listed for discovery; the registry allows read-only calls only |
navigate_to_plan | Navigates the user to a specific plan detail page. Use IDs returned by any page tool that lists plans. Navigation is blocked if the target URL leaves feverup.com. | Listed for discovery; the registry allows read-only calls only |
search_plans | Searches for plans in the current city. Returns a list of matching events with their IDs, names, URLs, and dates. Use navigate_to_plan to open a specific result. | Callable read-only tool |
toggle_plan_favorite | Adds or removes a plan from the user's favorites. If the plan is already a favorite it will be removed; otherwise it will be added. Works on any page that shows plan cards (gallery or calendar view). | Listed for discovery; the registry allows read-only calls only |
webmcp_get_page_summary | Returns a high-level summary of the current page and the list of available tools. Call this first on any page to understand context and capabilities. | 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 Fever changes its tools. - No account needed. These calls are credential-free registry reads. For tools that need a session on feverup.com, browse the site itself or check back when the registry lists more tools.
