 A Context Server is a server listening for JSON-RPC requests over stdin/stdout. The server must follow the Model Context Protocol (defined below) in order to declare its capabilities such that Zed can make use of them.
 
+### Implementing a Context Server
+
+Context Servers are JSON-RPC servers communicating over stdio. Context Servers must comply with the [Model Context Protocol (MCP)](./model_context_protocol).

+See [python-context-server](https://github.com/zed-industries/python-context-server) for a minimal working example.

+Currently, Zed's client only implements a subset of the protocol required to support custom prompt insertions and manipulations. This is likely to be expanded in the future.

 If your slash commands are already implemented in a language other than Rust, wrapping them in a Context Server implementation will likely be the fastest way to plug them into Zed.
