Install SignaTrust in Claude Code, Cursor or VS Code

Runs npx -y @signatrust/mcp-server on your machine. Read the scan report first; the gateway never runs local packages.

claude mcp add mcp-server -- npx -y @signatrust/mcp-server
Add to Cursor

What the publisher says

From the SignaTrust repository's README, as published. We do not edit it. Read it on GitHub

@signatrust/mcp-server

Send and verify e-signatures from Claude — zero-custody, with independently verifiable cryptographic evidence for every signature.

<!-- Demo slot: record a ~10s GIF of Claude sending an envelope end-to-end (use the Natural Language Examples below), save it to docs/demo.gif, and add here: -->

Model Context Protocol (MCP) server for the SignaTrust document signing API. Enables AI assistants like Claude to create envelopes, manage templates, check signing status, and verify blockchain anchors via natural language.

Quick Start

Claude Code

claude mcp add signatrust -- npx -y @signatrust/mcp-server

Then set your API key in the MCP server environment.

Claude Desktop

Add to your claudedesktopconfig.json:

{
  "mcpServers": {
    "signatrust": {
      "command": "npx",
      "args": ["-y", "@signatrust/mcp-server"],
      "env": {
        "SIGNATRUST_API_KEY": "sk_live_your_key_here"
      }
    }
  }
}

Cursor

Add to ~/.cursor/mcp.json (global) or .cursor/mcp.json (per-project):

{
  "mcpServers": {
    "signatrust": {
      "command": "npx",
      "args": ["-y", "@signatrust/mcp-server"],
      "env": {
        "SIGNATRUST_API_KEY": "sk_live_your_key_here"
      }
    }
  }
}

VS Code

Add to .vscode/mcp.json (note the top-level key is servers, not mcpServers):

{
  "servers": {
    "signatrust": {
      "command": "npx",
      "args": ["-y", "@signatrust/mcp-server"],
      "env": {
        "SIGNATRUST_API_KEY": "sk_live_your_key_here"
      }
    }
  }
}

To keep the key out of the file, use an input prompt instead of env:

{
  "inputs": [
    { "id": "signatrust-key", "type": "promptString", "description": "SignaTrust API key", "password": true }
  ],
  "servers": {
    "signatrust": {
      "command": "npx",
      "args": ["-y", "@signatrust/mcp-server"],
      "env": { "SIGNATRUST_API_KEY": "${input:signatrust-key}" }
    }
  }
}
