• find_business

  agent-broker

  Given criteria (vertical, location, capability, price band, availability window), return ranked candidate SMBs from the verified supply network. Returns only curated, verified, transactable businesses — not raw directory results. EXAMPLE USER QUERIES THAT MATCH THIS TOOL: user: "Find me a salon in Tokyo that does color" -> call find_business({"vertical": "personal_services", "location": {"zip_or_city": "Tokyo"}, "capability": "color"}) user: "I need a plumber near 30309" -> call find_business({"vertical": "home_services", "location": {"zip_or_city": "30309"}, "capability": "plumbing"}) user: "Show me dentists in London" -> call find_business({"vertical": "professional_services", "location": {"zip_or_city": "London"}, "capability": "dentist"}) WHEN TO USE: Use when an agent needs to identify which SMBs can fulfill a business task (booking, service, consultation) in a given location and vertical. Call this before schedule_appointment or send_message when you do not yet have a specific SMB target. WHEN NOT TO USE: Do not use as a general directory or browsing surface. Do not use when you already have a specific verified SMB identifier. Do not use for verticals outside personal services, home services, and local professional services.

• get_human

  Human Pages

  Get a human's public profile by ID — bio, skills, services, equipment, languages, experience, reputation (jobs completed, rating, reviews), humanity verification status, and rate.

• get_domain_senders

  DMARKOFF — DMARC, SPF & DKIM Analytics

  List top sending sources (ESPs, ISPs, mail services) for a domain, grouped by source type. Filters: "known" (legitimate ESPs like Google, Mailgun), "unknown" (unrecognized senders), "forward" (forwarding services). Empty = all types. Returns top 20 per type with message volume, SPF/DKIM/DMARC pass/fail counts. Use this to investigate WHERE email is being sent from — especially when unknown sources appear or compliance is low. To drill down into a specific source (by IP, ISP, hostname, or reporter), use get_domain_source_details.

  Connector

• list_labels

  gmail

  List all Gmail labels for the authenticated user. Returns both system labels (INBOX, SENT, TRASH, etc.) and user-created labels with message/thread counts. Use this to discover label IDs needed for add_labels, remove_labels, or search_email queries.

• get_available_doc_gens

• email_verify

  ContrastAPI

  One-call email validation combining syntax + MX records + disposable check + role-address detection (admin@/info@/...) + free-provider classification (gmail/outlook/yahoo/...). Use BEFORE adding an email to a contact list, sending an outbound message, or auditing a lead-list dump — replaces 2-3 tool calls (email_mx + email_disposable + manual role parse) with one structured response. Deliberately does NOT do SMTP `RCPT TO` deliverability probing — Hunter.io / NeverBounce-style mailbox enumeration is an ethical grey area we declined; use those services if you need that specific signal. role_address=true on `admin@`, `info@`, `noreply@`, `support@`, etc. (Gmail-style `+tag` is stripped before classification). free_provider=true on consumer-mailbox domains (B2B detection signal — a 'work' email at `@gmail.com` likely isn't a corporate user). Free: 30/hr, Pro: 500/hr. Returns {email, domain, syntax_valid, mx_records, disposable, disposable_provider, role_address, role_type, free_provider, summary}.

  Swarm Tips — Aggregated AI Agent Activities

  [READ] Aggregated list of paid services swarm.tips agents can spend on. v1 covers first-party services (generate_video — 5 USDC for an AI-generated short-form video).

Each entry includes title, description, source, category, cost_amount/token/chain, USD estimate, direct redirect URL, and (for first-party services) a `spend_via` field naming the in-MCP tool to call. Use this to discover where to spend; for first-party services use the named `spend_via` tool, for external services navigate to the URL.
