How do I use signalis-mcp?

1. Click on "Deploy Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@signalis-mcp What's in the latest intelligence digest?" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

signalis-mcp

MCP server for Signalis — pay-per-call global intelligence for AI agents. Read the current Master Intelligence digest (narratives, signals, markdown analysis), poll for new digests, and drill into the AI-business Pulse layer: active narratives with lifecycle stage and momentum, per-narrative detail with source attribution, historical narrative digests, and raw scraped content. Pay per call with USDC on Base via x402 — no signup, no accounts, no API keys.

5 free tools — no wallet, no API key (incl. digest feedback).
5 paid tools — flat per-call USD prices, settled in USDC on Base Mainnet via x402.

Try before you pay: the free get_sample tool returns a recent digest so you can learn the exact response shape first.

Quick start

Free tier (no wallet)

{
  "mcpServers": {
    "signalis": {
      "command": "npx",
      "args": ["-y", "signalis-mcp"]
    }
  }
}

You get get_brief, get_index, get_sample, get_latest, submit_feedback.

Paid tier (with wallet)

Add an EVM wallet private key (0x-prefixed) that holds USDC on Base Mainnet:

{
  "mcpServers": {
    "signalis": {
      "command": "npx",
      "args": ["-y", "signalis-mcp"],
      "env": { "PRIVATE_KEY": "0x..." }
    }
  }
}

The paid tools then settle each call automatically.

Install snippets

Claude Code:

claude mcp add signalis -- npx -y signalis-mcp
# with a wallet:
claude mcp add signalis --env PRIVATE_KEY=0x... -- npx -y signalis-mcp

Claude Desktop / Cursor: add the JSON block above to your MCP config (claude_desktop_config.json or .cursor/mcp.json).

How payments work (x402)

Signalis speaks the x402 exact scheme. The API's 402 advertises a Base (USDC, EIP-3009) rail; this MCP settles on Base:

The MCP requests a paid endpoint. With no payment, the API replies HTTP 402 with the accepted terms.
If PRIVATE_KEY is set, the MCP settles the call via the standard @x402/fetch V2 client and retries. If no key is set, the MCP returns the 402 price terms so you can see the cost without paying.
The API returns the data plus a payment block.

Compute-first, settle-after: Signalis computes the full answer before charging, so you are never billed for an error.

No accounts, no API keys — just a wallet with USDC on Base Mainnet.

Environment variables

Variable	Required	Description
`PRIVATE_KEY`	No	0x-prefixed wallet key with USDC on Base Mainnet. Required to pay the 5 paid tools on a live API. Free tools work without it; without a key the paid tools surface the 402 price terms.
`SIGNALIS_API_URL`	No	Override the API base URL (default `https://api.signalis.dev`).

A4/5.0

Scored 2026-08-02 07:35 across 10 tools

Disambiguation4/5

Most tools target distinct resources, but get_brief and get_latest both return digest content, and get_pulse_narratives vs get_pulse_narrative require careful reading. Descriptions clarify the differences, so confusion is unlikely but possible.

Naming Consistency4/5

The dominant pattern is get_<resource> with clear nouns (brief, index, sample, latest, history, narratives, etc.). The one outlier is submit_feedback, which uses a verb instead of get, but the rest are highly consistent.

Tool Count5/5

10 tools is well-scoped for an intelligence API that offers free instant access, paid historical data, pulse narratives, and raw content. Each tool covers a meaningful endpoint without redundancy.

Completeness4/5

The toolset covers the core lifecycle: index polling, sample, latest digest, history, feedback, and pulse details. Missing a way to fetch a specific free digest by ID or search could slow agents, but most workflows are supported.
