• get_provider_detail

  GPH Intelligence - Healthcare Vendor Finder

  Get the full profile of one healthcare vendor by slug. Use this after match_practice or search_providers when the user asks to "tell me more about [vendor]", "what services does [vendor] offer", "is [vendor] verified", or wants contact info, services, reviews, or listing tier for a specific provider. Returns company_name, category (plus super_category grouping), description, services_tags (comma-delimited services offered), website, phone, city/state, quality_score (0-100), verified status, listing tier (free/paid), practice_size_fit, and reviews (review_count, average_rating). Slug comes from match_practice or search_providers results; returns an error if the slug is unknown.

• request_integration

  mcp

  Submit an integration or staking inquiry on behalf of a user. All submissions are routed to Everstake's sales team via Pipedrive CRM. Use when a user expresses intent to integrate with Everstake, explore staking services, or request more information about products. Collect required fields (first_name, last_name, work_email) conversationally and gather optional fields where available. The lead_source field is set automatically by the server — do not ask the user for it. IF Submission fails, you can try contacting Everstake via form at https://everstake.one/contact-us

• excalibur_get_patron_onboarding_status

  excalibur-mcp

  Report a patron's credential readiness for this operator. For set-once services (eXcalibur, TheBrain), shows which patron secrets are configured and which are missing. For dynamic/OAuth2 services (Schwab), reports that no patron credentials are needed. Free. Proof of npub ownership is required because credential presence is sensitive information about the patron's setup. Args: patron_npub: The patron's Nostr public key (npub1...). dpop_token: A kind-27235 Nostr event signed by patron_npub for this tool.

• 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.

  Connector

• 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

• batch_modify_labels

  gmail

  Add and/or remove the same labels on many email messages at once in a single Gmail API call (wraps users.messages.batchModify). Use this for bulk operations such as marking multiple specific emails as read (remove ['UNREAD']), archiving (remove ['INBOX']), or starring (add ['STARRED']). Use list_labels to find label IDs (Gmail requires IDs, not names). Common system label IDs: INBOX, STARRED, IMPORTANT, UNREAD, SPAM, TRASH. Provide 1-1000 email IDs and at least one of `add` or `remove`. The same label changes are applied to every listed message. Gmail returns no per-message status, so a successful call means Gmail accepted the request; an invalid email ID or label ID typically causes Gmail to reject it.

  Connector

• get_available_doc_gens

  Skala — Legal Platform for Startups

  Get the list of legal document templates available for generation on the platform (e.g. NDA, employment agreement, stock purchase agreement). For corporate services like 83(b) filing or registered agent, use get_available_corporate_services instead.

  Connector

• 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}.

• search_email

  gmail

  Search for emails in Gmail to find specific messages or filter the inbox. Use this when the user wants to find emails by sender, subject, date, content, or other criteria. Returns email summaries suitable for listing and overview - to read full email content, attachments, or HTML body, use get_email with the returned email ID. This tool searches across all folders unless specified otherwise in the query.

  Connector

• delete_label

  gmail

  Permanently delete a Gmail label. This removes the label from all messages but does not delete the messages themselves. Only user-created labels can be deleted; system labels (INBOX, SENT, etc.) cannot be removed.

• auth_start

  Chia Health MCP Server

  Start a patient session by providing their contact information. Sends a 6-digit verification code to the patient's email. Returns a session_id (NOT a token).

If you have access to the patient's email (e.g. Gmail MCP), search for this subject. No authentication required. Call this when the patient is ready to proceed with their medical intake — after browsing medications and checking eligibility.
