Xsignal is an MCP server with 6 tools an agent can call, among them get_intent, get_preflight, get_screen. It answers at https://xsignal-production.up.railway.app/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 23 October 2026, succeeded.
x402 pay-per-call data tools for Base agents. Flagship get_intent ABSTAINS instead of guessing.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
get_intent | FLAGSHIP. 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 Inputs: addr, min_confidence, question |
get_preflight | The 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 Inputs: addr |
get_screen | BATCH 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 /scree Inputs: addrs |
get_signal | Real-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 Inputs: query, candidates, terms, source, limit |
get_token_brief | A 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 Inputs: addr, query |
get_token_intel | Base 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 Inputs: addr |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://xsignal-production.up.railway.app/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
