MCP Integration

UniChat AI supports Model Context Protocol (MCP) servers for extending AI capabilities with tools and resources. To configure MCP servers:

1. Navigate to Settings > MCP Servers
2. Add a new server configuration:

{
  "name": "filesystem",
  "command": "npx",
  "args": ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/directory"]
}

Learn more about available MCP servers in the MCP documentation.

API Keys

UniChat AI requires API keys to access different LLM providers:

• OpenAI: Get API key
• Anthropic: Get API key
• Google Gemini: Get API key

API keys are securely stored in your system's credential store and never shared.

For Developers

Architecture

UniChat AI uses a modular architecture with these key components:

1. UI Layer: Electron with React/Vue components
2. Provider Layer: Adapters for different LLM APIs
3. MCP Layer: Integration with MCP servers
4. Storage Layer: Local database and file system interaction

Adding New LLM Providers

To add support for a new LLM provider:

1. Create a new adapter in src/api/providers/
2. Implement the ProviderInterface
3. Register the provider in src/api/providerRegistry.ts

See the Developer Guide for detailed instructions.

Troubleshooting

Common Issues

• API Connection Issues: Verify your API keys and internet connection
• MCP Server Not Connecting: Check your MCP server configuration and ensure the correct paths
• Missing Messages: If conversations disappear, check the application logs for database errors
