Signaturit MCP server

The Signaturit MCP is an integration server that connects to Signaturit's e-signature services through their public API. It enables you to manage signature requests programmatically, including creating new requests, retrieving details, sending reminders, and canceling active requests.

Capabilities

The MCP server provides these core functionalities:

• get_signature: Retrieve details of specific signature requests
• create_signature: Generate new signature requests with support for:
  • Multiple signers
  • Email or SMS delivery
  • Custom expiration times
  • Sequential or parallel signing workflows
  • Personalized messages
  • Webhook notifications
• send_signature_reminder: Send reminders to pending signers
• cancel_signature: Cancel active signature requests

Prerequisites

Before installing the Signaturit MCP server, ensure you have:

• Go 1.16 or higher (verify with go version)
• An active Signaturit account (register at Signaturit)
• API key from your Signaturit dashboard

Installation

1. Clone the repository

git clone https://github.com/yourusername/signaturtit_mcp.git
cd signaturtit_mcp

2. Install dependencies

go mod download

3. Build the application

# Build for your current platform
go build -o bin/signaturtit_mcp cmd/server/main.go

# For Linux specifically
GOOS=linux GOARCH=amd64 go build -o bin/signaturtit_mcp cmd/server/main.go

Configuration

Setting up API Authentication

The server requires your Signaturit API key for authentication:

export SIGNATURIT_SECRET_TOKEN='your_api_key_here'

Running the Server

After building and configuring your environment variables:

./bin/signaturtit_mcp

Usage Examples

Creating a Signature Request

To create a new signature request using the MCP server:

1. Prepare your request with recipient information
2. Specify delivery method (email or SMS)
3. Set expiration and workflow parameters
4. Send the request to the server

Example request structure:

{
  "recipients": [
    {
      "email": "[email protected]",
      "name": "John Doe"
    },
    {
      "phone": "+1234567890",
      "name": "Jane Smith"
    }
  ],
  "template_id": "template_12345",
  "delivery_type": "email",
  "expiration_days": 14,
  "sequential": true,
  "custom_message": "Please sign this document at your earliest convenience"
}

Retrieving a Signature Status

To check the status of an existing signature request:

# Example of using the get_signature capability
# (Implementation details depend on your MCP client)

Sending Reminders

For pending signers who haven't completed their signature:

# Example of using the send_signature_reminder capability
# (Implementation details depend on your MCP client)

Canceling a Signature Request

To cancel an active signature request:

# Example of using the cancel_signature capability with an optional reason
# (Implementation details depend on your MCP client)

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "signaturit" '{"command":"bin/signaturtit_mcp","args":[],"env":{"SIGNATURIT_SECRET_TOKEN":"${SIGNATURIT_SECRET_TOKEN}"}}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "signaturit": {
            "command": "bin/signaturtit_mcp",
            "args": [],
            "env": {
                "SIGNATURIT_SECRET_TOKEN": "${SIGNATURIT_SECRET_TOKEN}"
            }
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "signaturit": {
            "command": "bin/signaturtit_mcp",
            "args": [],
            "env": {
                "SIGNATURIT_SECRET_TOKEN": "${SIGNATURIT_SECRET_TOKEN}"
            }
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
