ask-llm MCP Server

What this does

ask-llm exposes a set of tools to Claude over the Model Context Protocol. After you add it to claude_desktop_config.json (snippet above) and restart Claude Desktop, those tools become callable inside any conversation.

This server needs the following environment variables to be set before it can run:

XAI_API_KEY
ASK_GROK_HARNESS
ASK_GROK_MODEL
ASK_GROK_REASONING_EFFORT
ASK_GROK_MAX_OUTPUT_TOKENS
ASK_GROK_TIMEOUT_MS

ASK_CLAUDE_TIMEOUT_MS
OLLAMA_HOST

Set these via the env object in your MCP config (see claude_desktop_config.json snippet above).
