• Environment variable configuration for security and convenience

Install Dependencies

bash cd jimengpic-mcp npm install

Build the Project

bash npm run build

Usage

Run Directly

bash node build/index.js

As an MCP Server

Configure this service in an MCP client (such as Claude Desktop, Cursor, etc.):

json { "mcpServers": { "jimengpic": { "command": "node", "args": ["/path/to/jimengpic-mcp/build/index.js"], "env": { "JIMENG_ACCESS_KEY": "Your AccessKey", "JIMENG_SECRET_KEY": "Your SecretKey" } } } }

Notes

1. Ensure that the network connection is normal and can access the Volcengine API
2. API calls consume credits, so please be mindful of usage
3. The generated image URLs have a time limit, it is recommended to download and save them promptly
4. Please comply with Volcengine's terms of use and Jimeng AI content policies

Troubleshooting

Common Errors

1. Environment variables not set: Ensure that the correct ACCESS_KEY and SECRET_KEY are set
2. Network connection issues: Check the network connection and firewall settings
3. Insufficient API quota: Check the Volcengine account balance and API call count
4. Non-compliant prompts: Ensure that the prompts comply with content safety guidelines

Debugging Methods

Add debug information when running: bash DEBUG=* node build/index.js
