## Usage First install and configure cross.stream: https://cablehead.github.io/xs/getting-started/installation/ ```nushell use gpt ``` ### gpt thread ### gpt mcp [Model Context Protocol](https://modelcontextprotocol.io/introduction) (MCP) servers are really just CLI tools that read from stdin and write to stdout. [cross.stream](https://github.com/cablehead/xs) [generators](https://cablehead.github.io/xs/reference/generators/) spawn CLI tools and package each line of output into event frames (.recv) while routing frames ending in .send as input, turning them into services you can interactively poke at. `gpt mcp` leverages this approach to provide a hands-on environment for experimenting with and understanding MCP servers. ## Features - Spawn an MCP server as a cross.stream [generator](https://cablehead.github.io/xs/reference/generators/) - List available tools on the server. ### Spawn an MCP Server Register your MCP server: ```nushell # gpt mcp register <name> <command> gpt mcp register filesystem 'npx -y "@modelcontextprotocol/server-filesystem" "/project/path"' ``` ### List Available Tools List the tools provided by the MCP server: ```nushell gpt mcp tools list filesystem ``` ``` ──#──┬───────────name────────────┬─────────────────────────────────────────────────────────────────────────description─────────────────────────────────────────────────────────────────────────┬─...─ 0 │ read_file │ Read the complete contents of a file from the file system.
