Inky MCP Server

MCP (Model Context Protocol) server for Inky that provides access to your personalized coding rules stored in Pinecone. This server acts as a bridge between Cursor IDE and your Inky backend API.

📦 Published on npmjs: https://www.npmjs.com/package/inky-mcp-server

Overview

The Inky MCP server allows you to access your personalized software rules directly from Cursor IDE. It connects to your hosted Inky API endpoint and retrieves rules from your Pinecone database.

Features

• ✅ List all your coding rules
• ✅ Filter rules by repository
• ✅ Secure API key authentication
• ✅ JSON-RPC 2.0 protocol compliance
• ✅ Compatible with Cursor IDE

Installation

The package is available on npmjs: inky-mcp-server

Using npx (Recommended)

npx -y inky-mcp-server

Using npm

npm install -g inky-mcp-server

Using pnpm

pnpm add -g inky-mcp-server

Using yarn

yarn global add inky-mcp-server

Configuration

1. Get Your API Token

First, you need to generate an MCP access token from your Inky account. The token will be in the format inky_....

2. Configure Cursor IDE

Add the following configuration to your Cursor settings. The configuration file location depends on your OS:

macOS/Linux: ~/.cursor/mcp.json
Windows: %APPDATA%\Cursor\mcp.json

Option 1: HTTP Transport (Recommended - Direct API Access)

{
  "mcpServers": {
    "inky": {
      "url": "https://your-domain.com/api/mcp",
      "headers": {
        "Authorization": "Bearer inky_YOUR_TOKEN_HERE"
      }
    }
  }
}

Option 2: Stdio Transport (Using MCP Server Package)

{
  "mcpServers": {
    "inky": {
      "command": "npx",
      "args": ["-y", "inky-mcp-server"],
      "env": {
        "API_KEY": "inky_YOUR_TOKEN_HERE",
        "INKY_API_URL": "https://your-domain.com"
      }
    }
  }
}

Environment Variables

• API_KEY (required): Your Inky MCP access token (starts with inky_)
• INKY_API_URL (optional): Your Inky API base URL. Defaults to:
  • NEXT_PUBLIC_APP_URL environment variable
  • http://localhost:3000 if not set

Usage

Once configured, the MCP server will be available in Cursor IDE. You can use it to:

List All Rules

Query all your coding rules:

List all my coding rules

Filter by Repository

Get rules for a specific repository:

Show me rules for repository [repository_id]

API Reference

The MCP server communicates with the Inky backend API using JSON-RPC 2.0 protocol.

Tools

list_rules

Lists all user's rules, optionally filtered by repository.

Parameters:

• repository_id (optional): Filter rules by repository ID

Example Request:

{
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "name": "list_rules",
    "arguments": {
      "repository_id": "repo_123"
    }
  },
  "id": 1
}

Example Response:

{
  "jsonrpc": "2.0",
  "result": {
    "content": [
      {
        "type": "text",
        "text": "[{\"id\":\"rule_123\",\"name\":\"TypeScript Best Practices\",\"content\":\"...\",\"version\":1,\"is_active\":true,\"repository_id\":\"repo_123\",\"created_at\":\"2024-01-01T00:00:00Z\"}]"
      }
    ]
  },
  "id": 1
}

Security

• API tokens are passed via environment variables (never hardcoded)
• All API requests use Bearer token authentication
• Tokens are hashed and stored securely in the database
• Each user can only access their own rules

Troubleshooting

Server Not Starting

Error: Error: API_KEY environment variable is required

Solution: Make sure you've set the API_KEY environment variable in your Cursor MCP configuration.

Connection Errors

Error: Backend API error

Solution:

1. Verify your INKY_API_URL is correct
2. Check that your API token is valid
3. Ensure the backend API is accessible

No Rules Returned

Solution:

1. Verify you have rules created in your Inky account
2. Check that your API token belongs to the correct user
3. Try listing rules without repository filter first
