### openmcpent
Integrated Inspector + MCP client basic functions, combining development and testing into one.
Test mcp tools, prompts and resources with a variety of tools.
Tested tools can be placed in the "Interactive Testing" module for large model interaction testing.
Complete project-level management panel for easier MCP project management at both project and global levels.
Supports multiple large models: DeepSeek, OpenAI, Qwen, Gemini, Grok, Mistral, MiniMax, Groq, Perplexity, Kimi, Ollama, OpenRouter and more.
Support XML mode and customized options for your tool selection.
### openmcp-sdk
once everything is tested and verified in `openmcpent`, you can deploy your mcp as an agent app with `openmcp-sdk` fastly and easily:
```bash
npm install openmcp-sdk
```
then deploy your agent with just lines of codes
```typescript
import { OmAgent } from 'openmcp-sdk/service/sdk';
// create Agent
const agent = new OmAgent();
// Load configuration, which can be automatically generated after debugging with openmcp client
agent.loadMcpConfig('./mcpconfig.json');
// Read the debugged prompt
const prompt = await agent.getPrompt('hacknews', { topn: '5' });
// Execute the task
const res = await agent.ainvoke({ messages: prompt });
console.log('⚙️ Agent Response', res);
```
output
```

## Project Concept
OpenMCP adopts a layered modular design. By assembling different modules, it can be implemented in different modes on different platforms.
