MCP (Model Context Protocol)

Connecting agents to external tools and services via an open integration standard.

UnderOcean integrates the Model Context Protocol (MCP) — an open standard for connecting AI agents to external tools, data sources, and services (filesystems, GitHub, Slack, databases, and custom servers).

Per-project integrations

Each project manages its own set of connected integrations:

  • A list of connected servers, configured by URL or launch command
  • The tools each one exposes, discovered automatically
  • Which tools are assigned to which agents
  • Connection health/status, with an on-demand test

Using tools in agents and flows

  • An agent can be assigned a set of tools directly, which the model may call during a single-agent execution.
  • A flow's tool-call step invokes a specific tool on a specific integration as one step in a larger workflow, so its output can be branched on, aggregated, or passed to another agent.
