How do I install Longpath?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does Longpath need an API key?

The publisher lists these environment variables: LONGPATH_CONFIG, LONGPATH_HOME, JAVA_HOME.

What transport does Longpath use?

Longpath runs locally over stdio.

Power your agent

Add this server

The publisher's own command. Not a PlugMCP endpoint.

Local command

uvx longpath==0.1.0

Credentials from the publisher

LONGPATH_CONFIG — Path to longpath.toml (java_home, mpxj_classpath, max_rows, allow_writes). Optional: .xer and MS Project XML need no config.
LONGPATH_HOME — Folder searched for longpath.toml when LONGPATH_CONFIG is not set (default: a longpath folder in %LOCALAPPDATA%, or ~/.local/share/longpath).
JAVA_HOME — A Java 11+ runtime, used only to open .mpp / P6 XML files through MPXJ (install longpath[mpp] for the MPXJ jars).
