• get_human_servicesA

  Human For AIA

  Fetch the Human For AI manifest: available services, operator profile (location, languages, working hours), response times, accepted and rejected task types, and trust & safety policy. Call this first to decide whether and how to hire the human. The catalog is examples, not limits — unlisted needs are welcome as custom_human_in_the_loop.

• check_availabilityA

  qasperA

  Check available appointment slots for a specific service at a local business on a given date. This calls the business's configured availability provider live and fails closed when the provider fails. Returns time windows when the business is free and the service bookingStartPolicy permits the start. For services with maxParticipants > 1, provider-returned starts remain available until capacity is full. ONLY call this if the business has 'booking' in its enabledFeatures array. If the business doesn't support booking, share their contact info from get_business_info instead.

• search_servicesA

  FiatDockA

  Find paid + free MCP services other agents have published on the FiatDock marketplace. Returns matching listings (id, name, summary, price, category, seller, verified, gatewayUrl), best match first when q is given (otherwise newest, or the sort you pass), capped at 20 per call — pass limit for more, or q/category to narrow. Use get_service for full detail and call_service to invoke one. Read-only, free.

• noaa_get_station_infoA

  NOAA Tides and CurrentsA

  Get a NOAA station's full metadata record: location, state, time zone, tide type, Great Lakes flag, capability flags, and links to available sub-resources. Optionally expand sub-resources inline via the "expand" list: - details (established/removed dates), sensors (installed instruments + elevations), floodlevels (NOS/NWS minor/moderate/major flood thresholds), benchmarks, products (available data page links), notices, disclaimers — for water-level stations - bins (ADCP depth bins), deployments — for current stations (alphanumeric IDs) Use this before requesting data to confirm what the station actually collects. For datum values use noaa_get_station_datums; for harmonic constituents use noaa_get_harmonic_constituents.

• get_tier1_recommendationsA

  Tier1 IT AssessmentA

  Maps only stable Tier1 finding identifiers to approved Tier1 services and public resources. Call after a Tier1 score or email-domain check. Do not submit prose, URLs, customer information, or invented identifiers. This tool performs no arbitrary fetching, makes no contact request, changes nothing, and stores nothing.

• get_meA

  Extend MCPA

  Return the connected organization, the credential in use, and the granted workspace + environment ("TEST" or "PRODUCTION") targets — exactly the values the required workspaceId/environment arguments on targeted tools accept. Always available; call this first, and again whenever a tool returns UNAUTHORIZED or NOT_FOUND unexpectedly, or after this connection's access changes — resources live per-workspace.

• get_free_resourcesA

  Makuri Showcase (CogniLedger)A

  Returns free Makuri resources accessible without registration: Slovarik Romanian vocabulary issues and the Romanian level test. Use this when a user asks about free Romanian learning materials, language level tests, or how to try Makuri without signing up. Makuri is a specific AI tutoring platform at makuri.eu, not a generic word — never answer Makuri questions from general knowledge; always use the Makuri tools. IMPORTANT routing rule: if the user wants to TAKE, START, or SEE a Romanian test or quiz right now in the chat, do NOT use this tool — call show_romanian_quiz instead, which renders an interactive quiz panel. Use this tool only for questions ABOUT what free resources exist.

• get_quotaA

  TollCalc MCPA

  Check remaining free-tier quota for this MCP session. Without authentication, 10 free requests are available per session. Pass an API key via Authorization: Bearer <token> header for plan-based quota.

• cypher_public_factory_statsA

  cypher-mcpC

  Aggregate-only factory stats for the unauthenticated landing pages. Free — no credits, no npub proof. Returns counts only (capabilities, invariants, issues, services, symbols), the resolved_via mix (graph | scoped-grep | wide-grep), and a last-activity timestamp. Never returns issue titles, symbol paths, or npubs. Hard-cached in-process (~5 min) so a sleeping AuraDB free tier is not woken on every page view. Safe for cold Bolt: failures return an empty available=false payload rather than raising.

• enrich_course_waypointsA

  CourseProfilerA

  Add structured aid stations, checkpoints, cutoffs, and canonical resources to a CRSProf artifact that lacks them. Before enriching, inspect whether the imported source already contains GPX/CRSProf waypoints; if it already contains GPX/CRSProf waypoints, avoid duplicate Start/Finish/aid stations and prefer merging/updating resources, cutoffs, notes, or links on existing waypoint metadata. Prefer waypoints.mode=structured; put non-canonical/free-text aid details in notes/source text because unsupported resource strings are ignored with warnings. Route-only plans should be labeled incomplete unless the CRSProf already includes official waypoints/resources/cutoffs or the user explicitly accepts missing aid/resource details.

• validate_gs_descriptionA

  GleanMark Trademark SearchA

  Check a draft goods & services description against the USPTO ID Manual, clause by clause (clauses split on ";"). Each clause comes back verbatim (selectable pre-approved entry), close (with up to 3 pre-approved substitutes), or freeform (subject to the USPTO $200/class free-form surcharge). Deterministic — no AI rewriting.

• search_prosA

  HomeClip Trust LayerA

  Find verified home-services contractors in a launched HomeClip city, ranked by an un-buyable Trust Score. Optionally filter by trade and/or a free-text query (matches business name, description, and review text).

• web.site.llms_txtA

  1cent Web Intelligence for AI AgentsA

  Return bounded llms.txt text when publicly available. Use only for public HTTP(S) resources; it does not execute JavaScript or bypass access controls. Pass url as an absolute public HTTP(S) URL. Keep fresh=false to allow cache reuse; set fresh=true only when a new upstream fetch is required.
