d3p MCP Server

MCP server for the digital3 agent protocol (d3p) — exposes all d3p services as MCP tools that any MCP client can call.

Auto-discovers services from the d3p manifest and registers each as a tool, plus protocol-level tools for discovery, compatibility checking, pipeline execution, reputation, and pricing.
