"An email protocol for sending and receiving messages" matching MCP tools:

• send_message

  local-mcp

  Sends an iMessage via the Mac's Messages.app to a recipient handle (phone number with country code, e.g. +14155551234, or an Apple ID email). This is a write operation: the first call (without confirm) returns a preview; call again with confirm=true to actually send. Direct (1:1) iMessage only — sending into an existing group chat isn't supported yet. Requires Messages.app signed in to iMessage + Automation permission.

• check_email_domain_security

  Tier1 IT Assessment

  Runs bounded, point-in-time public DNS checks for one validated public domain through Cloudflare 1.1.1.1 DNS over HTTPS. Call only after showing the exact domain, record types, resolver, no-application-persistence statement, infrastructure-metadata limitation, and receiving explicit user approval. Set approved=true only when that approval exists. Never send an email local part, IP literal, internal hostname, URL, credentials, or arbitrary instructions. DKIM requires an explicit selector or a confirmed provider's small documented selector set; absence at a queried selector never proves DKIM is absent. The tool cannot prove overall email security and stores no submitted domain or result.

• utm_builder

  Moltline Outbound Engine

  Build a UTM-tagged URL for campaign tracking. FREE. Typical input {"url": "https://example.com/pricing", "source": "newsletter", "medium": "email", "campaign": "spring-launch"} returns {"tagged_url": "https://example.com/pricing?utm_source=newsletter& utm_medium=email&utm_campaign=spring-launch"}. Use to build one tagged tracking URL. Not for analyzing campaign results and not for anything that belongs in the message body (audit_copy). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "url must start with http(s)://"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

• sequence_planner

  Moltline Outbound Engine

  Plan an outreach cadence with expanding gaps and per-touch purposes. FREE. Spaces N touches across D days, alternating channels. Typical input {"touches": 5, "days": 14, "channels": ["email", "linkedin"]} returns {"days": 14, "plan": [{"touch": 1, "day": 0, "channel": "email", "purpose": "open with a specific, researched reason"}, ...], "rule": "..."}. Use when cadence and per-touch purpose are the question. Not for the wording of any single message (audit_copy). Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

• robyn_message_send

  Robyn — Gasless Cross-Chain for AI Agents

  Relays a message you sealed locally with /svc/msg2-sdk.mjs (seal(mailbox, inner) → {ephemeralPubKey, viewTag, ct}). This tool cannot encrypt for you: sending plaintext here would expose it to the relay, so it only accepts the sealed triple. Replay-idempotent (a resend returns duplicate:true). The message appears in the public feed at releaseAt. If you cannot run the SDK, use v1 (POST /api/messages/send) and know that v1 is plaintext.

• chieflab_send_approved_email

  ChiefLab

  [chieflab_* alias of chiefmo_send_approved_email] Send an approved launch email through the email sending rail (current adapter: resend). USE WHEN the user has approved an email publishAction from chiefmo_launch_product and you need to fire the send. Strict approval gate (same shape as chiefmo_publish_approved_post). `from` MUST be on a domain verified at the adapter (resend.com) — check chieflab_list_email_senders first. Single recipient or short list (≤50). Money/external-system action — once sent cannot be unsent.

• decode_irs_notice

  Arc & Ledger Tax Tools

  Use this when a user mentions receiving an IRS or state tax letter or notice and wants to know what it means, the deadline, or what to do. Give it the notice code (e.g. CP2000, CP14, LT11) and optionally the notice date and amount shown. Set brief:true for a shorter answer.

• clear_sandbox

  MisarMail MCP Server

  Delete every email captured in the sandbox. The sandbox holds messages intercepted during testing so they are never delivered to real recipients. This DELETES ALL of them and cannot be undone — but it touches only intercepted test mail, never sent campaigns, real inbox messages, contacts, or templates. Takes no parameters and offers no filter: it is all or nothing. Requires an API key. Clearing an already-empty sandbox is harmless. Read anything you still need from the sandbox before calling this.

  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}.

  Connector

• discovery_signup

  Disco

  Create a Disco account and get an API key. Provide an email address to start the signup flow. If email verification is required, returns {"status": "verification_required"} — the user will receive a 6-digit code by email, then call discovery_signup_verify to complete signup and receive the API key. The free tier (10 credits/month, unlimited public runs) is active immediately. No authentication required. Returns 409 if the email is already registered. Args: email: Email address for the new account. name: Display name (optional — defaults to email local part).

  Connector

• read_messages

  Almured

  Read messages from a consultation thread (own thread for responders; any thread for askers). WHEN TO USE - Before replying to a consultation thread — check the full history first. - To retrieve a scope_proposal's deliverable_type and metadata before sending scope_accepted. - To check if an extension_request was accepted. WHEN NOT TO USE - For full consultation content (question, responses) — use get_consultation. BEHAVIOR - Read-only. Auth required. Rate-limited to 60 req/min. - Visibility: askers see all threads on their consultation; responders see only their own thread. - Returns messages in chronological order (oldest first) with kind, body, metadata, from_agent_id, created_at. WORKFLOW - Responders: call read_messages before send_message to avoid duplicate proposals. - Askers: call read_messages with responder_agent_id to check a specific thread before sending scope_accepted.

• submit_feedback

  Senzing

  Request a free Senzing evaluation license or submit feedback. To get an eval license: set category='license_request', provide firstname (required), lastname (optional), email (work email required — personal domains rejected), and how_heard. A 10-day, 250K-record license is generated and emailed with a download link. One per email, re-requestable after 30 days. To submit feedback: set category to bug/feature/question/general and provide message. Show the user the exact message and get confirmation before sending.

  Connector

• chieflab_connect_provider

  ChiefLab

  Connect a third-party provider (Zernio, Resend, GA4, Search Console, HubSpot, Stripe, Linear, Notion, Slack) to this workspace. USE WHEN the user wants to wire up publishing, email sending, or analytics readback. For OAuth providers (ga4 / search_console / hubspot) returns an authorizeUrl the agent surfaces to the user. For API-key providers (zernio / resend) returns instructions for the set-key tool. Without this, publish/send/measure tools return 'configure first' errors.

  Connector

• getThread

  email

  Get a conversation thread by id: metadata plus all inbound and outbound messages interleaved oldest-first. Each message has a direction (inbound/outbound) and id; fetch inbound message bodies via getEmail, or outbound bodies via getSentEmail. Discover thread_id from any email or sent-email record. Compare message_count against messages.length to detect truncation.

  Connector

• validate_email

  Qiniso

  USE THIS to check an email address's syntax AND that its domain TLD is real, before saving or sending — instead of trusting raw input. Validates the local part and domain (RFC 5321/5322 subset) and flags made-up TLDs. Does NOT check deliverability.

  Connector

• create_campaign

  LinkedIn MCP Server (Salesbot)

  Create a NEW campaign (saved as 'draft' — it does NOT start sending until the user activates it in the app). Provide a name, the profile_id to send from, and an ordered list of steps. Each step has an action ('connect', 'message' or 'visit'), an optional delay_hours (wait before this step), and AI/template settings for messages. Returns the new campaign_id. Use add_contacts_to_campaign next to add leads.

  Connector

• contract_send

  shiply

  Send a draft contract to the customer. Validates all 8 fields are non-empty, computes content_hash, flips project to contract_sent, fires the customer email. Same handler works for amendment drafts — sending an amendment does not move project state.

  Connector

• pictify_render_video

  mcp

  Render a video template to an MP4 video or an animated GIF, with variable substitutions. Common use cases: personalized video messages, social video posts, animated certificates, product announcement clips, and GIFs for places an MP4 cannot autoplay (chat, email, READMEs). GIF output: timeline templates are palette-converted and capped at 15fps / 720px wide; code (tsx) templates encode GIF natively at half the composition frame rate with no width cap. WORKFLOW: pictify_list_video_templates → pictify_get_video_template_variables → this tool. The render takes up to a few minutes; this tool waits and returns the hosted file URL. Each render consumes one video credit.

• web3.lookup

  Abstraxn

  Multi-chain wallet, token, ENS, and transaction-simulation lookups, paid per call in USDC/USDm directly from the caller's own wallet via the x402 protocol — no Abstraxn account needed. Pick one `action`: - wallet_balances ($0.005): token balances for a wallet across 20+ chains. Requires `chain` and `address`. - wallet_transactions ($0.005): transaction history with asset transfers for a wallet. Requires `address`. Optional `chain`, `limit`. - wallet_pnl ($0.01): realized and unrealized profit/loss per token for a wallet. Requires `chain` and `address`. - token_metadata ($0.002): name/symbol/decimals for a token contract. Requires `chain` and `address`. - ens_resolve ($0.001): resolve an ENS name to an Ethereum address. Requires `name`. - ens_reverse ($0.001): resolve an Ethereum address to its ENS name. Requires `address`. - tx_simulate ($0.01): simulate an EVM transaction before sending — gas estimate, execution trace, revert reason. Requires `network_id`, `from`, `to`. Optional `value`, `data`, `gas`. Prices above are indicative — the exact charge for a given call is always whatever the live payment challenge specifies for that request. The first call (no `paymentPayload`) returns `paymentRequired`; retry with the same arguments plus `paymentPayload` to complete payment and get the real result.
