The integration hub for your CRM, field service and accounting apps. One plugin, two separate parts: integrations between two of your systems, and AI agents inside one of them. It connects the CRM, field service, accounting and online store systems small businesses run on. Don't see your system? Request it, right in the chat. Part 1. Integrations between two systems Set up in the chat, then they keep two of your systems in sync by themselves, so a new customer, a won deal or a paid invoice shows up where your team works without copying it by hand. - See which systems connect and what two systems can sync, no account needed - Choose the records that travel, one way or both ways, and the moment they travel: when paid, won, accepted or overdue - Ready rules, such as a won deal that becomes a draft invoice - Which fields go across, and how each system connects - Set it up in the chat, or get a link that opens the setup prefilled - For CRM Connector customers: your integrations, what failed and why, sync now, pause or resume Part 2. AI Agents inside one system An AI agent works with the records of one of your systems. Request your system right in the chat: we arrange the setup and enable it for your account, then you sign in to it. - AI Analyst: it reads your customer data, such as contacts, deals and invoices, and finds the same customer in your other connected systems - AI Agent: it also changes records when you ask, each change shown first, risky ones approved by you in CRM Connector - Automations: fixed rules inside that one system (when this happens, only if, then do that), made in the chat, approved once by you in CRM Connector, then run by the platform by itself - A change log with undo where the system allows it - Nothing in AI Agents syncs between two systems: that is an integration You stay in control: - You choose per system and per record type what the assistant may see or change - Changing records is a separate permission on the consent page, off unless you allow it - An automation never runs before you approve it, and you can pause or remove it at any time - It never deletes a record and never records a payment - It sets up, runs or pauses an integration only when you ask and confirm, and never deletes one - Disconnect at any time in CRM Connector under Settings, AI Assistants

AgentiSend is a transactional email API: send through verified domains with a message log, budgets, a preflight and refusals that name the fix; built so AI agents can send on your behalf. The hosted MCP server at https://api.agentisend.com/mcp exposes 82 tools (44 on tools/list; the rest via list_more_tools). A send is one message or a batch of up to 500 items with per-item results. preflight_email runs every gate a real send runs, sends nothing, and costs nothing. Every 4xx returns code, message, and fix. There is no tool for unsolicited mail. Auth is a bearer API key or OAuth 2.1 with dynamic client registration. Starter prompts: "Send this receipt to the customer." "Preflight this send and tell me what would stop it." "What can I spend today?"
