P6-MCP

Primavera P6 MCP Server

An object-oriented, fully featured MCP server for Oracle Primavera P6 that works against two backends through one identical tool surface: (a) .xer schedule files on disk, and (b) a live P6 EPPM instance via the P6 EPPM REST API.

🚀 60-Second Quickstart

Footnotes:

Live P6 EPPM backend capabilities may vary depending on P6 EPPM release and configured permissions
Some older P6 EPPM releases may not implement all REST endpoints (marked with ⚠️ in detailed documentation)
Mutation tools require explicit confirm=True parameter for live P6 EPPM backend
XER backend supports all tools unless specifically noted as "Live backend only"
Live P6 EPPM backend supports all standard tools unless specifically noted as "Live P6 EPPM only"
