MCP Slash Commands

MCP server prompts are automatically registered as slash commands in CLI and TUI chat interfaces.

Command Discovery​

Prompts are automatically discovered and registered when MCP servers are initialized:

# List available slash commands
rad mcp prompts

Command Format​

Slash commands use the format /prompt-name:

  • Prompt names are normalized (spaces → underscores, lowercase)
  • Example: "Search Database" becomes /search_database

Using Slash Commands​

In CLI Chat​

rad chat assistant
> /search_database query="SELECT * FROM users"

In TUI​

Type slash commands directly in the chat interface:

> /search_database query="SELECT * FROM users"

Command Arguments​

Arguments are passed as space-separated values:

/search query text here

Arguments are converted to JSON based on the prompt's argument schema.

Help Command​

View available slash commands:

# In chat
/help

# Or list MCP commands specifically
/mcp-commands

Command Execution​

  1. Command is parsed from input
  2. Lookup in slash command registry
  3. Server identified from registry
  4. Prompt executed via MCP
  5. Result displayed

Example Prompts​

  • /search - Search functionality
