You can run the MCP Perplexity Server to quickly test MCP-based messaging by sending a message and receiving it back. This lightweight Python-based service is ideal for validating client integrations, diagnosing transport issues, and verifying echo-style interactions within the MCP ecosystem.

How to use

To use this MCP server, start the executable provided by the installed package and connect your MCP client to it. You will send a message to the Echo endpoint, and the server will return the exact same message. This behavior makes it ideal for validating message formatting, transport reliability, and end-to-end data flow during development and testing.

How to install

Prerequisites you need before installation.

Install from PyPI to obtain the MCP Perplexity Server quickly.
