• risetive_list_niche_playersA

  RisetiveA

  List up to eight leading products in one niche — current top products first, then by monthly visits — each with its one-line description, monthly visits, referring domains and pricing. Use it to see who leads a niche; use risetive_list_new_entrants for the newest products in it. No pagination. Works without signing in (small daily allowance, at most 5 rows per list); a free Risetive account returns full results.

• plan_rotationA

  WarmInboxes Free Deliverability ToolsA

  Suggests a two-batch inbox rotation schedule: the fleet split in half, one batch sending while the other rests, swapped every 1, 2 or 4 weeks. Returns batch sizes, the daily load per active inbox compared with a 15-a-day pace, how many inboxes the volume needs at that pace, and an eight-week calendar. A suggested schedule only: it does not pause, resume or change any inbox or sequencer.

  The eight thinking-failure problems ContextOverflow covers, phrased the way a human experiences them. Start here to see what exists.

• list_sourcesA

  DomduckA

  What Domduck reads and what each source means, including the eight AI crawlers whose robots.txt policy is tracked. A constant. Read it first: it is what lets a model interpret lookup_domain without guessing at field names or at which direction is better.

• search_medical_evidenceA

  CliniAtlas EvidenceA

  Live search of PubMed, Europe PMC and clinical guidelines. Returns up to eight sources for a clinical or research question, each with its study type, evidence level and link, usually in about 20 seconds. It does not write an answer: cite the sources by number, or use ask_cliniatlas for a full cited answer. For an EU medicine's label or SmPC, use lookup_eu_medicine. Do not include patient identifiers. Searches are limited per user per day.

• shoot_plan_reviseA

  Shoot PlanA

  Use the plan's one included revision. This cannot be undone and uses up that revision, so call shoot_plan_revision_preview first and confirm with the person. For structured plans, change filming time or transfer time (constraintUpdates.availableMinutes, locationTransferMinutes), framing, or structuredChanges. Use the full taskId from shoot_plan_list (not planId). A unique eight-character task prefix or orderReference also works. Connections see only their own live or owner-test plans.

• chparl_get_businessA

  switzerland-parliament-mcp-serverA

  Read a Swiss parliamentary business by canonical eight-digit businessId or exact published short number. Choose overview for metadata and available text sizes; texts for original published text, automatically outlined when several fields exceed the disclosure budget; or status_history, bills, related_business, preconsultations, or subjects for independently paged relationships. textFields selects complete original fields only in texts, even when large. Paging applies only to relationships. Use subjects to narrow chparl_search_transcripts; source text and HTML remain unchanged.

  ActableSite AI Crawler MonitorA

  Check the homepage robots.txt rule for eight named OpenAI, Anthropic, Perplexity, and Google AI crawler tokens.

• astro_planet_boardA

  CycleCalcs AstronomyA

  All eight planets in one call for a date and optional location: constellation, magnitude, apparent size, elongation from the Sun, morning or evening sky, retrograde state with the next station, rise/set, and a worth-looking-tonight assessment. The right tool for "which planets are visible tonight". For exact coordinates of specific bodies use astro_positions.

• validate_agent_cardA

  Agent Discovery Doctor - llms.txt, agent card, mcp.jsonA

  FIRST CALL, needs nothing: {"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"no_arguments_check_this_hosts_own_discovery_documents","arguments":{}}} — Validates a pasted /.well-known/agent-card.json against the nine fields A2A marks required and each skill's id/name/description/tags, and warns on capabilities declared true that a reader will then try. Example: json='{"name":"a"}' returns the eight missing fields.

• list_countriesA

  CodePostalProA

  Coverage overview: the eight curated countries with postal-code format, hierarchy labels (e.g. state › city › ZIP), key facts (capital, population, area, currency, calling code) and time zones — plus `bulk_tier` with per-country postal-code counts for the ~115 additional countries served from GeoNames. Call it once if unsure whether a country is covered.

• create_access_roleA

  Higgs HubB

  Create a named access role in a workspace you own. It starts with all eight capabilities on and every mailbox read & write; narrow it afterwards with set_access_role_capability and set_access_role_mailbox_access, then put people in it with assign_access_role. This only stages a request: the owner opens the link in their browser, reviews it, and approves it there with their agent PIN. Never ask for or accept the PIN in chat.

• compare_filingA

  SEC FilingsA

  Use when someone asks what changed between a filing and the one before it, such as this year's 10-K against last year's. Compares the filing with the preceding available reporting period of the same company and form. Returns full sentence-change counts and bounded examples for up to eight sections, and reports when no prior filing is available. It is a sampled comparison, not a complete redline.
