MCP Server

Server URL https://mcp.seamless.ai/mcp · Auth OAuth 2.1 or API key · Credits same as the matching REST API

Introduction

The Seamless.AI MCP server exposes the catalog as tools an AI agent can call directly: search contacts and companies, research them, manage lists and saved searches, build campaigns, send email, log calls, and read activity. Your agent picks the right tool from a plain-English request, with no API code to write.

Tool domain	Tools	Matching REST API
Search	`search_contacts`, `search_companies`, `lookup_locations`	Contact Search, Company Search, Location Lookup
Research	`research_contacts`, `research_companies`, `poll_contact_research`, `poll_company_research`	Contact Research, Company Research
User	`get_credits`, `get_my_contacts`, `get_my_companies`	My Contact Data, Account
Engagement	Lists, saved searches, campaigns, templates, email, calls, tasks, activity	Engagement API

The full tool list is in the MCP docs.
