Welcome! This project features multiple MCP clients integrated with Google Gemini AI to execute tasks via the Model Context Protocol (MCP) — with and without LangChain.
Happy building, and don’t forget to subscribe!
This repository includes four MCP client options for various use cases:
| Option | Client Script | LangChain | Config Support | Transport | Tutorial |
|---|---|---|---|---|---|
| 1 | client.py |
❌ | ❌ | STDIO | Legacy Client |
| 2 | langchain_mcp_client.py |
✅ | ❌ | STDIO | LangChain Client |
| 3 | langchain_mcp_client_wconfig.py |
✅ | ✅ | STDIO | Multi-Server |
| 4 | client_sse.py |
❌ | ❌ | SSE (Loca & Web) | SSE Client |
If you want to add or reuse MCP Servers, check out the MCP Servers repo.
✅ Connects to an MCP server (STDIO or SSE)
✅ Uses Google Gemini AI to interpret user prompts
✅ Allows Gemini to call MCP tools via server
✅ Executes tool commands and returns results
✅ (Upcoming) Maintains context and history for conversations
Choose the appropriate command for your preferred client:
- Legacy STDIO —
uv run client.py path/to/server.py - LangChain STDIO —
uv run langchain_mcp_client.py path/to/server.py - LangChain Multi-Server STDIO —
uv run langchain_mcp_client_wconfig.py path/to/config.json - SSE Client —
uv run client_sse.py sse_server_url

- You send a prompt:
Create a file named test.txt
- The prompt is sent to Google Gemini AI.
- Gemini uses available MCP tools to determine a response.
- The selected tool is executed on the connected server.
- The AI returns results and maintains conversation context (if supported).
