WebMCP Registry site · v0.18.35
Use sigiro with your agent.
sigiro (sigiro.com) registers 8 WebMCP tools. 8 of 8 tools declares readOnlyHint, so an agent can invoke them through tools.call. The registry runs the tool in a fresh headless page on sigiro.com and returns untrusted site content.
This page mirrors the WebMCP Registry listing for sigiro.com, last live-checked by the registry at 2026-09-22T23:01:49.047Z. Run ghostget webmcp sites.get --input '{"domain":"sigiro.com"}' --json for the current schema; the listing can drift between checks.
Use sigiro 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":"sigiro.com"}' --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":"sigiro.com","tool":"diagnose_service","input":"{}"}' --jsonRegistered WebMCP tools
sigiro publishes 8 tools on sigiro.com; 8 declare readOnlyHint.
| Tool | What it does | Callable through Ghostget |
|---|---|---|
diagnose_service | Diagnose one service over a time window when an incident needs root-cause analysis; returns ranked findings, anomaly flags, bounded samples, and drill-down SQL. | Callable read-only tool |
get_navigation | Return the documentation navigation tree (header tabs and the sidebar hierarchy), reflecting how the docs are organized for readers. Pass `locale` for a language's tree and, on a versioned site, `version` for an archived snapshot's tree. | Callable read-only tool |
get_page | Fetch a single documentation page as agent-optimized Markdown (frontmatter included, components downleveled to plain Markdown). Pass a route from `search_docs` or `list_pages`, e.g. `/guides/install`. | Callable read-only tool |
list_anomalies | List persisted telemetry anomalies when you need to choose an investigation; returns ranked anomalies and drill-down SQL. | Callable read-only tool |
list_pages | List every documentation page with its route, title, description, content type, and any declared facet values; pass `contentTypes`, `filters`, and/or `locale` to narrow the list. On a versioned site the list defaults to the current docs — p | Callable read-only tool |
list_services | List services with telemetry when you begin an investigation; returns each service and its observed time range. | Callable read-only tool |
run_query | Run read-only SQL when you need a telemetry drill-down; returns the query rows. | Callable read-only tool |
search_docs | Full-text search across the documentation. Returns matching pages with their title, route, content type, and a short excerpt; pass `contentTypes` to search only pages of certain types (e.g. `rfc`, `changelog`), `filters` to require facet va | 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 sigiro changes its tools. - No account needed. These calls are credential-free registry reads. For tools that need a session on sigiro.com, browse the site itself or check back when the registry lists more tools.
