twitter-signal-mcp

Live X/Twitter search and AI trend digests inside Claude, Cursor, or any MCP client — no Twitter/X API key, no subscription, no monthly minimum. Your agent pays a fraction of a cent per call in USDC on Base using x402.

x_search           $0.02/call    up to 20 newest matching tweets + engagement
x_digest           $0.05/call    the same tweets + an AI-written trend summary
x_leads            $0.05/call    the people behind matching posts, enriched (bio, website, emails, followers)
x_pain_points      $0.05/call    clustered complaints / feature requests / praise for a product, with quotes
x_user_timeline    $0.02/call    one account's own recent posts
x_profile          $0.02/call    one account's bio, stats, and links
x_tweet            $0.01/call    one tweet by ID, full text + engagement
x_replies          $0.02/call    the reply thread under one tweet
x_find_accounts    $0.02/call    accounts matching a name/topic, not posts
x_account_verdict  $0.02/call    AI read on whether an account is worth engaging
x_watch            $0.05/call    only the posts newer than your last check

Why this exists

The official X API starts at a monthly subscription and a developer-account approval. If an agent just needs to know what people are saying right now, that's a lot of setup for a handful of queries. This server charges per request instead — a hundred searches costs about sixty cents, and there is nothing to cancel.

Tools

x_search — $0.02

Full advanced-search syntax. Returns up to 20 newest matches with author handle, follower count, text, timestamp, permalink, likes, retweets, replies, and views. Need more than 20? A full answer ends with next.older — pass its cursor value back (same query) for the next 20 older matches, $0.02 a page. No slicing dates by hand.

x_digest — $0.05

Everything above plus an AI-written digest generated only from the returned tweets:

{
  "summary": "3-5 sentences on what's actually being said",
  "sentiment": "positive | negative | mixed | neutral",
  "sentiment_note": "why it leans that way",
  "key_themes": ["..."],
  "driving_accounts": ["@handle", "..."],
  "notable_post_urls": ["https://x.com/..."]
}

Use x_digest when you want the takeaway; x_search when you want the raw posts.

x_leads — $0.05

Same advanced-search syntax as x_search, but returns the PEOPLE behind the matching posts instead of the posts themselves — enriched with bio, website, emails found in the bio, follower count, location, a DM-open flag, and every matching post per person:

{
  "result_count": 20,
  "lead_count": 8,
  "leads": [{ "username": "someone", "followers": 5000, "emails": [], "matched_posts": [] }]
}

Inputs: query (required, same syntax as x_search), max (optional, "20" or "40" — default 20). Use for recruiting, cofounder search, B2B lead generation, influencer discovery, community sourcing.

x_pain_points — $0.05

Pass a product or brand name/handle, get clustered complaints, feature requests, and praise mined from live X posts, with verbatim quotes and URLs:

{
  "product": "Cursor",
  "analysis": { "summary": "...", "pain_points": [{ "theme": "...", "count": 4, "severity": "medium" }] }
}

Input: product (required — a name or an X handle). Use for product research, competitor research, churn signals, roadmap input.

x_user_timeline — $0.02

An account's own recent posts (originals, replies, retweets), newest first. Input: username (required). Use: x_user_timeline username="elonmusk" to track a competitor's or founder's own feed.

x_profile — $0.02

One account's bio, website, location, join date, follower/following counts, and verified status. Input: username (required). Use: x_profile username="cursor_ai" to qualify a lead before you reach out.

x_tweet — $0.01

One tweet by numeric ID: full text, author, timestamp, permalink, engagement. Input: id (required). Use: x_tweet id="1859012345678901234" to re-check a specific post you already found.

x_replies — $0.02

The reply thread under one tweet, newest first. Input: id (required, same as x_tweet). Use: x_replies id="1859012345678901234" to see how people reacted to a specific post.

x_find_accounts — $0.02

Search for ACCOUNTS matching a name, keyword, or topic — not posts. Input: query (required, same syntax as x_search). Use: x_find_accounts query="solar installer hawaii" to build a shortlist of accounts to follow up on.

x_account_verdict — $0.02

A short AI-written read on one account: what it's about, how active/engaged it is, and whether it's worth following up with. Input: username (required). Use: x_account_verdict username="someone" to triage a lead fast without reading the profile yourself.

x_watch — $0.05

Same search as x_search, but only returns posts newer than a cursor you supply. Inputs: query (required), since (optional — an ISO timestamp or the cursor.newest_id from your last x_watch call). Use: poll a brand/ticker/hashtag on a schedule without re-paying for posts you've already seen. A check that finds nothing new is not charged — you only pay when there is news.

Query syntax (x_search, x_digest, x_leads, x_find_accounts, x_watch)

Both tools take one query string:

Setup

You need a Coinbase CDP wallet funded with a little USDC on Base — that wallet pays per call. Create one at portal.cdp.coinbase.com (API key + wallet secret).

Claude Desktop — add to claude_desktop_config.json:

{
  "mcpServers": {
    "twitter-signal": {
      "command": "npx",
      "args": ["-y", "twitter-signal-mcp"],
      "env": {
        "CDP_API_KEY_ID": "your-key-id",
        "CDP_API_KEY_SECRET": "your-key-secret",
        "CDP_WALLET_SECRET": "your-wallet-secret",
        "X402_MAX_PRICE": "0.05"
      }
    }
  }
}

X402_MAX_PRICE is a hard per-call ceiling in USD. If the endpoint ever quotes more than this, the request is refused before anything is signed — no charge. The default 0.05 already covers every tool above (the priciest are x_digest, x_leads, x_pain_points, and x_watch at $0.05) — you don't need to raise it.

Cost & safety

• You are only ever charged for a successful response. Invalid queries are rejected before payment (HTTP 400, no settlement).

• Nothing found = nothing charged. An empty x_search / x_digest / x_leads / x_pain_points / x_watch comes back as no_results with charged: false — the payment is never settled.

• Same call within 10 minutes = free. Repeat the exact call from the same wallet and you get the saved answer (meta.charged: false) at no cost.

• If the upstream tweet source fails after payment, the API returns an explicit error and logs the call for refund rather than pretending it worked.

• Gas is covered by the facilitator — you spend USDC only.

• Identical queries within 60 seconds are served from cache.

How it works

MCP client → twitter-signal-mcp → 402 challenge → sign USDC authorization
           → facilitator settles on Base → data returned

Protocol: x402 v2 (CAIP-2 networks, PAYMENT-REQUIRED challenge header). A v1 client cannot talk to this API.
