Overview

AI-generated overview

A local stdio MCP server that gives an assistant SignNow API reference documentation and integration guidance for e-signature development.

What you can do
  • Fetch SignNow API reference documentation, endpoints and parameters
  • Provide sample code for common SignNow API operations
  • Explain authentication methods and token management
  • Offer best practices for e-signature workflows and troubleshooting of error codes
When to use it
Useful when building or debugging a SignNow e-signature integration and you want the assistant to look up API details and produce example code in the same conversation.
Requirements
Runs locally over stdio as a Python package (sn-api-helper-mcp), launched via uvx, the CLI entry point, or python -m sn_api_helper_mcp serve. No environment variables, headers or credentials are declared; it is desktop-only.
Before you install
The README describes help with SignNow authentication and token management, so treat any credentials you discuss with care; the server itself declares no authentication and no environment variables. Only one tool, get_signnow_api_info, is documented, so the other listed capabilities may be guidance rather than live API calls.

Installation

In SourceWeft

  1. Open SignNow Api Helper MCP in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Core Functions:

  • API Documentation Access: Retrieve and display SignNow API documentation, endpoints, and parameters.
  • Code Examples: Generate and provide sample code for common SignNow API operations.
  • Authentication Help: Assist with SignNow API authentication methods and token management.
  • Integration Guidance: Provide best practices for implementing SignNow e-signature workflows.
  • Error Resolution: Help troubleshoot common SignNow API issues and error codes.

Use Cases:

  • Document Signing Workflows: Help implement complex signing processes with multiple signers.
  • API Integration: Generate code for uploading documents, creating signature requests, and tracking status.
  • Development Support: Provide real-time assistance during SignNow API development.
  • Best Practices: Ensure proper implementation of SignNow security and compliance requirements.

📦 Installation

To install locally for development: pip install -e .

🚀 Run

You can run the server using Python or uvx:

Method 1: Python modulepython -m sn_api_helper_mcp serve

Method 2: Installed CLI entry pointsn-api-helper-mcp serve

Method 3: UVX uvx sn-api-helper-mcp

🔌 Integrations & Setup

You can use this server with any MCP client. Below are the configurations for the most popular IDEs and apps.

1. Claude Desktop

To use SignNow tools directly inside the Claude app:

  1. Open your config file:
    • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
    • Windows: %APPDATA%\Claude\claude_desktop_config.json
  2. Add the following to the mcpServers object:
jsx
{  "mcpServers": {    "signnow-api-helper": {      "command": "uvx",      "args": [        "sn-api-helper-mcp"      ]    }  }}
  1. Restart Claude Desktop.

2. Cursor AI

Cursor supports MCP natively.

  1. Open Cursor Settings (Cmd/Ctrl + ,).
  2. Go to Features > MCP Servers.
  3. Click + Add New MCP Server.
  4. Add the following to the mcpServers object:
jsx
{  "mcpServers": {    "signnow-api-helper": {      "command": "uvx",      "args": ["sn-api-helper-mcp"]    }  }}

3. Visual Studio Code (via Cline)

VS Code uses the Cline extension (or similar MCP clients) to interact with MCP servers.

  1. Install the Cline extension from the VS Code Marketplace.
  2. Open Cline settings (click the gear icon inside the Cline chat window) -> MCP Servers.
  3. Add the configuration JSON:
jsx
{  "signnow-api-helper": {    "command": "uvx",    "args": [      "sn-api-helper-mcp"    ]  }}

✨ Features

  • Transport: stdio only
  • Available Tools:
    • get_signnow_api_info - Fetching API reference documentation.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
