Model Context Protocol (MCP) Support ​

CodeCompanion implements the Model Context Protocol (MCP) to enable you to connect the plugin to external systems and applications. The plugin only implements a subset of the full MCP specification, focusing on the features that enable developers to enhance their coding experience.

Usage ​

To use MCP servers within CodeCompanion, refer to the tools section in the chat buffer usage section of the documentation.

If enabled, the servers will be started when you open a chat buffer for the first time. However, you can use the MCP slash command to start or stop servers manually.

Prompts from running servers can be added to the chat buffer with the MCP prompts slash command.
