# MCP REST API and CLI Client
A **simple REST API** and **CLI client** to interact with [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) servers.
## Key Features
### 1. MCP-Compatible Servers
- Supports any [MCP-compatible servers](https://github.com/punkpeye/awesome-mcp-servers) servers.
- Pre-configured default servers:
- **SQLite** (test.db has been provided with sample products data)
- **Brave Search**
- Additional MCP servers can be added in the [mcp-server-config.json](mcp-server-config.json) file
### 2. Integrated with LangChain
- Leverages LangChain to execute LLM prompts.
- Enables multiple MCP servers to collaborate and respond to a specific query simultaneously.
### 3. LLM Provider Support
- Compatible with any LLM provider that supports APIs with function capabilities.
- Examples:
- **OpenAI**
- **Claude**
- **Gemini**
- **AWS Nova**
- **Groq**
- **Ollama**
- Essentially all LLM providers are supported as long as they provide a function-based API. Please refer [langchain documentation](https://python.langchain.com/docs/integrations/chat/) for more details.
## Setup
