# 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

- What are indie developers posting about MCP this week?

- What products has this person been talking about lately?

- Has anyone shared revenue for this kind of app on X?

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")
```

The five circles and their member counts, first 5 rows:

| id | name | n_core | n_extended |
|---|---|---|---|
| ai_founders | AI 创始人 | 141 | 95 |
| ai_indie | AI 独立开发者 | 84 | 50 |
| ai_researchers | AI 研究员 | 147 | 99 |
| sv_vc | 硅谷 VC | 91 | 92 |
| us_stock_investors | 美股顶级投资人 | 103 | 90 |

## How fresh the data is

This is today’s output of `coverage` (row counts and date ranges per table):

| first_post | last_post | posts | authors | last_fetch |
|---|---|---|---|---|
| 2026-09-25 | 2026-11-11 08:09:37+08:00 | 39,004 | 525 | 2026-11-11 20:10:01+08:00 |

## 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.

## FAQ

**How do I query it from Claude Code, Cursor or Codex?**
It is one library inside the Stringers remote MCP server. Sign in with Google at stringers.io/en/start.html to get a personal URL, paste the prompt to your agent and it configures itself; then just ask — the agent calls the data tool with lib "x".

**Is it free?**
Free during beta: 200 queries per account per day, up to 50 rows per query.
