Details
ContextX was introduced as a free remote MCP server that connects Grok search to AI tools such as Claude Code, pi, and Codex, which can have difficulty accessing the internet or searching Twitter posts. MCP is a way to connect external functions to AI tools. It provides Grok 4.3 general search and Grok 4.20 multi-agent in-depth search, in which multiple agents search together.
It can be used by writing an MCP JSON configuration, and no API key is needed. No specific configuration examples or additional steps are provided.
It supports streaming, which sends results sequentially and prevents timeouts on intermediary connection servers (gateways). The project is public on GitHub. The usage period and regional restrictions need to be confirmed.
