• check_headersA

  ContrastAPIA

  Validate HTTP security headers you provide (JSON): CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Permissions-Policy, Referrer-Policy against best practices. Use to test header config before deployment or validate non-public servers; use scan_headers to fetch live. Free: 30/hr, Pro: 500/hr. By default header values are truncated to 500 chars; pass include='full' for the full raw value. Returns {total, by_severity, findings}. No external requests.

• wait_for_videoA

  vivideoA

  Wait for a video to reach a terminal state (completed / failed / preview), then return it. Polls safely at the API-suggested interval for up to ~20 seconds per call (HTTP requests are time-capped). If it does not finish in time it returns { timed_out: true } with the latest status — simply call it again with the same id to keep waiting. It never blocks indefinitely or over-polls.

• enrich_providerA

  apis-ioA

  One call, pick your field groups — resolves a slug OR any identifier and returns exactly the groups you ask for, instead of chaining get_provider + get_provider_rating + get_provider_artifacts + get_provider_onboarding. Groups: profile, onboarding, artifacts, rating, insights. Understanding plan — the base groups moved with the rest of the discovery layer on 2026-08-31. Priced B2 (cross-catalog synthesis) — $0.05 per call under pay-as-you-go; included in Understanding and Influence. See apis://prices.

• get_transcript_audioA

  transcriptionA

  Return a time-limited signed URL for the source audio or video of an existing transcription, so it can be handed to another tool or streamed. Valid for one hour and supports HTTP Range requests. This reads back media that already exists — it does not transcribe anything and costs nothing. Requires an OAuth 2.1 user access token.

• seo_test_web_mcpA

  mcp-seoA

  Tests a live website or local endpoint for Web MCP enablement: Checks Streamable HTTP (/mcp), Legacy SSE (/sse), discovery manifests (/.well-known/mcp/server-card.json, llms.txt), CORS headers, and provides copy-paste implementation blueprints in 11 programming languages. USAGE GUIDELINES: - Use to test if a web application exposes an agent-accessible Model Context Protocol interface. - Do NOT use for regular HTML search engine optimization; use 'seo_audit_technical' or 'seo_audit_onpage' instead. BEHAVIORAL TRANSPARENCY: - Safe, read-only protocol diagnostic probe. Makes HTTP GET/HEAD requests to standard discovery endpoints. Modifies no files.

• create_bucketA

  Webhook StudioA

  Provision a new webhook endpoint (a "bucket") that captures incoming HTTP requests. Returns its id, public ingest url to point a provider at, inbox_url (the live human view to hand back), and signing secret. Pass external_ref — your own stable name like "acme-api:stripe" — so you can re-find this exact bucket later with list_buckets after losing context.

USAGE GUIDELINES: - Use to audit indexing, crawlability, canonicalization, and technical header directives. - Do NOT use for on-page copy, headings, or keyword targeting; use 'seo_audit_onpage' instead. - Do NOT use for full site audits; use 'seo_audit_sitemap_multipage' or 'seo_generate_full_audit' instead. BEHAVIORAL TRANSPARENCY: - Safe, read-only diagnostic evaluation. - Issues HTTP GET requests if given a URL; reads local file if given a file path. No disk modifications.

• measure_domainA

  ai-crawler-readinessA

Use it for any site the index has not reached yet, or when the caller wants a fresh verdict after changing robots.txt or a WAF rule. Returns the same `fixes` list as domain_readiness, derived from the fresh measurement.
