Posts from five X circles: an MCP database you can query from Claude Code or Cursor

Updated daily, last 2026-11-12 · MCP data · lib x

Original posts from core members of five X circles (AI founders, AI indie developers, AI researchers, Silicon Valley VCs, US stock investors), searchable by circle, keyword or person, plus live X search.

What you can ask

These are example phrasings. Once connected, ask in plain language; the agent decides which table to query and how to filter.

Example: a real query and what it returned today

Your agent calls the MCP data tool like this (you never write it yourself — you just ask):

data(lib="x", args="circles")

Limits: what this data cannot tell you

Circle membership is hand-curated, not all of X; live X search is limited to 50 calls a day.

Connect these databases to your own agent (Claude Code, Cursor, Codex…)

It is a remote MCP server: sign in with Google, paste one prompt and your agent configures itself, then ask in plain language inside your project. Free during beta: 200 queries a day, up to 50 rows each.
