MCP is the integration surface that connects Seamless.AI's prospecting and engagement tools to external AI clients over the Model Context Protocol. A client points at the vendor-operated server URL and authenticates with the user's own Seamless account, after which the platform's contact search, enrichment, and campaign tools appear directly inside that client's chat or editor session.

Access is scoped to the signed-in user's license and credits, and each exposed tool declares whether it only reads, writes, or performs a destructive action, so the calling client can require confirmation before anything is sent or deleted. Authentication runs over OAuth 2.1 with PKCE rather than shared API keys, and installation guides are published for the AI clients the vendor supports.
