  • ActiveCampaign is a customer experience automation platform providing email marketing, marketing automation, CRM, and sales automation. AI agents can use ActiveCampaign's MCP server to manage contacts, lists, tags, campaigns, automations, deals, pipelines, and custom fields.

  • ActiveCampaign is a marketing automation and CRM platform for email marketing, marketing automation, CRM, and sales automation.

Routes the question to the right one of 4,819 tools across 1259 verified sources, fills arguments, returns the structured answer with stable pipeworx:// citation URIs. Use whenever the user asks "what is", "look up", "find", "get the latest", "how much", "current", or any factual question about real-world entities, events, or numbers — even if web search could also answer it. Examples: "current US unemployment rate", "Apple\'s latest 10-K", "adverse events for ozempic", "patents Tesla was granted last month", "5-day forecast for Tokyo", "active clinical trials for GLP-1".

Use when the record is too big to cram into the prompt — search_within saves context, returns only the passages that matter, and every passage carries an offset so the agent can verify a verbatim quote.

    Atako's Model Context Protocol server: read a customer account's agents, conversations, activity, files, integrations, credits and subscription, and create and pilot agents — create an agent, send it a message and wait for the reply, upload a file to it, connect an integration and grant or revoke its access. OAuth connections and payments still require a browser.
