Grok Native Search MCP

A minimal stdio MCP Server providing three read-only tools:

• web_search(query): Grok native Web Search

• x_search(query): Grok native X Search

• web_fetch(url): Jina Reader web page to Markdown

Search always uses grok-4.6, reasoning.effort: low, and max_turns: 1. Complementary searches may run in parallel within a single turn, stopping once enough first-hand evidence is found, and expanding scope only when evidence is missing or conflicting. Tool responses are not parsed or rewritten; they are returned directly as MCP text.

Tool routing: use web_fetch for known URLs or when page content needs verification; use x_search for X posts, accounts, threads, and trends; use web_search for other web-wide searches without a specific URL. After a search returns an external URL that needs verification, continue by calling web_fetch.
