@prism/mcp-server

The MCP server for AI agents that need real-time financial truth. Drop it into Claude Desktop, Cursor, ChatGPT, OpenClaw, Hermes, or any MCP host and your agent inherits every PRISM tool — crypto, equities, on-chain, prediction markets, and macro — behind one PRISM_API_KEY.

• Package: @prism/mcp-server · Current: 1.0.1

• Runtime: Node.js 18+

• Upstream API: https://api.prismapi.ai

• Tool surface: 21 financial-data tools

• Live guide: https://www.prismapi.ai/quickstart

• Landing: https://www.prismapi.ai

Connect your agent in 30 seconds — pick a path

1. One-click install (recommended)

• Cursor and VS Code support deep-link MCP installs. The buttons on the PRISM landing (https://www.prismapi.ai/#connect) handle the config write for you in a single click.

2. Six-line MCP config (any host)

{
  "mcpServers": {
    "prism": {
      "command": "npx",
      "args": ["-y", "@prism/mcp-server"],
      "env": { "PRISM_API_KEY": "prism_sk_..." }
    }
  }
}

Paste into your host's MCP config file (Claude Desktop: claude_desktop_config.json, others: their equivalent). Restart the host. Done.

3. Instant key — no signup

curl https://api.prismapi.ai/auth/keys/instant

Returns a 7-day prism_sk_… key, no account required. Rate limit: 3 keys / hour per IP. Drop it into the PRISM_API_KEY slot above.

4. ChatGPT custom GPT

Import the OpenAPI spec directly: https://api.prismapi.ai/openapi.json — every endpoint becomes a callable tool inside a Custom GPT. No MCP needed.

Environment

• PRISM_API_KEY (required)

Scripts

npm run dev   # tsc --watch
npm run test  # vitest

Promote an instant key into your account

Got a prism_sk_… from path 3 above and want its usage to show up in your PRISM dashboard? Sign up, then paste it into API Keys → Link Agent Key: https://www.prismapi.ai/dashboard/keys. The key is now owned by your account — same prism_sk_…, but billing + usage + the 7-day expiry attach to you.

Notes

• This server depends on the prism-os SDK (workspace) — the published artifact bundles it via prepack, so consumers npm i with zero extra deps.

• Keep this README aligned with package.json for version + tool-count claims. Single source of truth for connect-method ordering is the PRISM landing's ConnectYourAgent section.
