X Search Plugin

MCP plugin for read-only X/Twitter research through xAI's Responses API x_search tool. It is packaged for Codex and Claude Code, supports xAI OAuth login for entitled X Premium, Premium+, and SuperGrok accounts, and falls back to XAI_API_KEY when no usable stored OAuth credential is present.

This is not a browser scraper. The plugin calls https://api.x.ai/v1/responses with xAI's server-side x_search tool and returns Grok's answer plus citations when xAI provides them.

Copy-Paste Agent Prompt

Paste this into Codex or Claude Code to have the agent set up and verify the plugin for you:

Set up x-search-plugin from https://github.com/Ilevk/x-search-plugin for this machine.

Use uv. Prefer xAI OAuth, but if I already have XAI_API_KEY configured, use that as the fallback. Do not ask me to paste access tokens, refresh tokens, API keys, browser cookies, or credential file contents into chat.

Steps:
1. Clone or update the repository.
2. Register the x-search-plugin MCP server for the current agent client.
   - Codex: use codex mcp add or the Codex plugin marketplace flow.
   - Claude Code: use claude mcp add --transport stdio.
3. Run uv run --quiet --locked python scripts/x_search_auth.py status.
4. If no credential is configured, ask me to run uv run --quiet --locked python scripts/x_search_auth.py login locally.
5. Run uv run --quiet --locked python scripts/smoke_mcp.py.
6. Confirm the MCP tools are available, then try a read-only X search for recent posts from @Lo_gan__.

Keep this read-only. Do not post, like, follow, DM, or mutate any X account state.

Quickstart for Codex

Prerequisites: uv, Codex CLI with MCP support, and either an xAI OAuth-entitled X Premium, Premium+, or SuperGrok account, or XAI_API_KEY.

git clone git@github.com:Ilevk/x-search-plugin.git
cd x-search-plugin
codex mcp add x-search-plugin -- uv run --quiet --locked python "$PWD/scripts/x_search_mcp.py"
uv run --quiet --locked python scripts/x_search_auth.py login
uv run --quiet --locked python scripts/x_search_auth.py status
uv run --quiet --locked python scripts/smoke_mcp.py

For API-key usage instead, skip OAuth and set XAI_API_KEY before starting Codex:

export XAI_API_KEY="..."

Open a new Codex thread or restart Codex after changing credentials or MCP registration.

Quickstart for Claude Code

Prerequisites: uv, Claude Code with MCP support, and either an xAI OAuth-entitled X Premium, Premium+, or SuperGrok account, or XAI_API_KEY.

git clone git@github.com:Ilevk/x-search-plugin.git
cd x-search-plugin
uv run --quiet --locked python scripts/x_search_auth.py login
claude mcp add --transport stdio --scope user x-search-plugin -- uv run --quiet --locked python "$PWD/scripts/x_search_mcp.py"
claude

Approve the x-search-plugin MCP server if prompted, then check /mcp.
