longpath

A local, read-only MCP server that lets an assistant analyze Primavera P6 and MS Project schedules: critical path, float, DCMA 14-point checks, logic checks and

What you can do

Read and analyze P6 and MS Project schedule files, including .xer, MS Project XML and, with Java, .mpp and P6 XML files through MPXJ. Run critical path method (CPM) analysis and float calculations on the schedule. Apply DCMA 14-point and logic checks to flag schedule quality issues. Produce S-curves and other schedule views. Operates read-only by default, with writes gated by a configuration setting.

When to use it

Use it when you need to review, audit or explain a Primavera P6 or MS Project schedule without opening the scheduling software, for example to check schedule quality, float or the critical path before a project review.

Requirements

Runs as a local Python package (longpath) over stdio on a desktop machine. A Java 11+ runtime is needed only for .mpp and P6 XML files, set via JAVA_HOME, with the longpath[mpp] extra installed. Optional configuration through LONGPATH_CONFIG pointing to longpath.toml, or LONGPATH_HOME as the folder searched for it. No authentication declared.
