Claude AI Configuration

Add this configuration to your Claude Desktop settings (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "turtlestack-lite": {
      "command": "node",
      "args": ["/path/to/turtlestack-lite/src/index.js"]
    }
  }
}

Replace /path/to/turtlestack-lite/ with your actual installation path:

# Example paths:
# macOS: "/Users/yourusername/Projects/turtlestack-lite/src/index.js"
# Linux: "/home/yourusername/turtlestack-lite/src/index.js"  
# Windows: "C:\\Users\\yourusername\\turtlestack-lite\\src\\index.js"

🔒 Security Note: No API keys or secrets are stored in the configuration. All credentials must be provided through Claude commands for maximum security.

🔧 Configuration Setup

Important: This repository contains dummy placeholder values for all sensitive IDs and tokens. Before using the project, you must replace these placeholders with your actual credentials.

📝 Required Replacements

The following files contain placeholder values that need to be replaced with your actual credentials:

1. Test Files (for development/testing):

• tests/debugAuthentication.js:16,17 - Replace YOUR_CLIENT_ID_HERE and YOUR_PROGRESS_TOKEN_HERE

• tests/testClaudeConnection.js:21,22 - Replace YOUR_CLAUDE_SESSION_TOKEN_HERE and YOUR_CLAUDE_CLIENT_ID_HERE

• tests/testGrowwOrderFix.js:13 - Replace YOUR_GROWW_API_KEY_HERE

• tests/testGrowwOrderReference.js:11 - Replace YOUR_GROWW_API_KEY_HERE

• tests/debugAuthentication.js:44 - Replace YOUR_GROWW_JWT_TOKEN_HERE

• tests/testClaudeConnection.js:40,52 - Replace YOUR_GROWW_JWT_TOKEN_HERE

2. Cloudflare Configuration (for Cloudflare Workers deployment):

• bridge.js:4 - Replace YOUR_WORKER_SUBDOMAIN.YOUR_USERNAME.workers.dev

• cloudflare/wrangler.toml:17 - Replace YOUR_KV_NAMESPACE_ID_HERE

• cloudflare/mcp-config-for-claude.json:5 - Replace worker URL in the embedded command

🔑 How to Get Your Credentials

For Kite (Zerodha):

1. Go to Kite Connect Developer Console

2. Create an app to get api_key and api_secret

3. Generate access token using the authentication flow

For Groww:

1. Use browser developer tools to inspect network requests on Groww web app

2. Extract JWT token from Authorization header

3. Token format: eyJraWQiOiJ... (long JWT string)

For Dhan:

1. Go to Dhan API Portal

2. Get your access_token and client_id

For Cloudflare Workers:

1. Create KV namespace: wrangler kv:namespace create "SESSIONS_KV"

2. Note the namespace ID from the output

3. Update your worker subdomain based on your Cloudflare account

⚠️ Security Best Practices

• Never commit real credentials to version control

• Use environment variables for production deployments

• Rotate tokens regularly for security

• Test with dummy data first before using real credentials

🧪 Quick Setup for Testing

Replace these specific placeholders to get started quickly:

# 1. Update test files with your tokens
sed -i 's/YOUR_GROWW_JWT_TOKEN_HERE/your_actual_groww_token/g' tests/testClaudeConnection.js
sed -i 's/YOUR_GROWW_API_KEY_HERE/your_actual_api_key/g' tests/testGroww*.js

# 2. Update Cloudflare config (if using workers)
sed -i 's/YOUR_WORKER_SUBDOMAIN.YOUR_USERNAME.workers.dev/your-worker.your-account.workers.dev/g' bridge.js
sed -i 's/YOUR_KV_NAMESPACE_ID_HERE/your_actual_kv_id/g' cloudflare/wrangler.toml
