Pulse Verity MCP server

Pulse Verity Index

pulse-verity connects an AI agent to the Pulse Verity Index: signed, verifiable crypto index prices through the Model Context Protocol (MCP).

It exposes five read-only tools:

There are no write tools. This package contains no Pulse platform engine code. It only calls the public Pulse Verity Index API.

Try it without a key

The server starts and answers with no configuration at all. Keyless, it serves getindexprice for BTC, ETH and SOL from the free sample:

claude mcp add pulse-verity -- npx -y pulse-verity

Then ask your agent for the Bitcoin index price. Successful price receipts are signed and verifiable, exactly like a keyed one.

Add a key for everything else

A free key enables catalogue access, batch reads and settlement prints, subject to usage limits. Create a developer account at thepulse.markets/developers, verify your email, then create a key. Keep it in your MCP client's private configuration; do not share it in chat. Signature verification also works without a key.

claude mcp add pulse-verity \
  --env PULSE_API_KEY=pidx_your_key_here \
  -- npx -y pulse-verity

For any stdio MCP client:

{
  "mcpServers": {
    "pulse-verity": {
      "command": "npx",
      "args": ["-y", "pulse-verity"],
      "env": { "PULSE_API_KEY": "pidx_your_key_here" }
    }
  }
}

Hosted: nothing to install

The same five tools run on Pulse's side at https://mcp.thepulse.markets/api/index/mcp.

• Claude (web, desktop, mobile): Settings → Connectors → Add custom connector → paste the URL → Connect, then sign in with your developer email and password.
• ChatGPT: Settings → Connectors → Create → paste the URL. Same sign-in.
• Claude Code: claude mcp add --transport http pulse-verity https://mcp.thepulse.markets/api/index/mcp --header "Authorization: Bearer pidxyourkey"
• Any client with remote MCP support: { "url": "https://mcp.thepulse.markets/api/index/mcp", "headers": { "Authorization": "Bearer pidxyourkey" } }

Sign-in is standard OAuth 2.1 (dynamic registration, PKCE). Every hosted call meters against your key exactly like a REST call. Discovery documents live at /.well-known/oauth-authorization-server and /.well-known/oauth-protected-resource/api/index/mcp.

Claude Code / Cowork plugin

For the guided price-check skill, pinned pulse-verity@1.2.6 MCP runtime, local setup and three example prompts, see the Claude plugin guide. Keyless samples are available; wider access requires the user's own key and applicable allowance. Cowork runtime constraints are documented in the guide. This package is separate from the Desktop MCPB; directory approval is not implied.

Cursor marketplace package

This repository includes .cursor-plugin/plugin.json and mcp.json for Cursor's plugin loader. The plugin starts the released pulse-verity@1.2.6 package with npx; Node.js 18 or newer is required. No platform engine code or private repository access is included.

The PULSEAPIKEY variable is optional and defaults to an empty string, so BTC, ETH and SOL samples work without a key. Configure a free key through Cursor's plugin configuration to enable catalogue, batch and settlement-print requests. Never put a real key in these repository files.

Shortened. The full README is on GitHub.
