    How to connect

    How to connect xsignal to Claude

    The server address to paste into Claude settings:

    https://xsignal-production.up.railway.app/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    Authorization

    After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

    The server address to paste into ChatGPT settings:

    https://xsignal-production.up.railway.app/mcp

    1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
    3. Open Settings → Connectors and click Create.
    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).

    get_intentFLAGSHIP. An outcome-priced momentum verdict that ABSTAINS below your confidence bar - the only x402 signal that refuses to answer (honestly) when it is not sure. Post {addr, min_confidence 0-1} then pay $0.01, and get a mechanical momentum verdict "gaining" or "fading" IF the signal agreement clears your bar, else a calibrated "abstain". Paid answers carry a keyless tamper-evidence receipt. confidence is a transparent heuristic, NOT a prediction; not financial advice. x402-paid at GET/POST /intent (3 free calls per wallet via ?wallet=0x…). Example: GET /intent?addr=0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed&min_confidence=0.7
    get_token_briefA fused MEAL: one call combines Base token market intel + real-time social signal into a single "what is happening with $TOKEN right now" brief - market flags + top CITED social posts + a plain-language, non-advisory summary. Saves an agent the fetch-and-fuse work. x402-paid at GET/POST /brief ($0.05; 3 free per wallet via ?wallet=0x…). Example: GET /brief?addr=0x4ed4…&q=degen
    get_signalReal-time X/social signal for a topic: scored (virality + freshness) and CITED (source urls), deduped and ranked. Input: query (topic) OR candidates[] (bring your own posts to score). x402-paid at GET/POST /signal ($0.01; 3 free per wallet via ?wallet=0x…). Example: GET /signal?q=base+memecoin
    get_token_intelBase token MARKET data (liquidity, 24h volume, price + change, pool age, buy/sell flow, mechanical flags) from public DEX pools. Market data, NOT a trust/safety rating. Best used as an input to get_token_brief. x402-paid at GET/POST /token ($0.01; 3 free per wallet via ?wallet=0x…).
    get_preflightThe Base PREFLIGHT: one call fuses MainStreet on-chain SAFETY (SAFE/WATCH/AVOID + rug flags) with xsignal MOMENTUM (the abstaining read) into a single recommendation (GO / CAUTION / AVOID / AVOID_ENTRY / NEUTRAL / UNVERIFIED) answering "is this token safe to touch AND moving?". Safety GATES momentum - never green-lights a token that can rug. x402-paid at GET/POST /preflight ($0.05; 3 free per wallet via ?wallet=0x…). Input: addr (0x Base token). Not financial advice.
    get_screenBATCH watchlist screen: run the preflight (safety ⊕ momentum) over up to 10 Base tokens in one call → which are GO (safe + moving), plus a per-token verdict + a summary count. For an agent screening a watchlist. x402-paid at GET/POST /screen ($0.10; 3 free per wallet via ?wallet=0x…). Input: addrs (array or comma-separated 0x addresses). Not financial advice.
