# MCP A simple example of a client and server using the Connect API. ## Usage Run an MCP server: ```bash CONNECT_API_KEY="" SWAGGER_FILE="swagger.yaml" make server ``` Then run the MCP client: ```bash make client ``` Modify the chat in the main function of `app.py` to ask different questions. ## Swagger Usage The code below is a snippet of how to register Swagger tools with Chatlas. ```python import chatlas import requests from openapi_mcp.chatlas import SwaggerTool from openapi_mcp.connect_api import map_operations_to_tools from openapi_mcp.swagger import ( expand_all_references, transform_swagger_to_operation_dict, ) api_url = "127.0.0.1:8000/" openapi_dict = requests.get(f"{api_url}/swagger.json").json() openapi_doc = expand_all_references(openapi_dict) operations = transform_swagger_to_operation_dict(openapi_doc) tools = map_operations_to_tools(operations) aws_model = os.getenv("AWS_MODEL", "us.anthropic.claude-3-5-sonnet-20241022-v2:0") aws_region = os.getenv("AWS_REGION", "us-east-1") chat = chatlas.ChatBedrockAnthropic(model=aws_model, aws_region=aws_region) for operation in api_operations.values(): SwaggerTool.register_tool( chat, SwaggerTool( base_url=api_url, operation=operation, ), ) ``` To see this in action, run a local OpenAPI-compatible server and run the Shiny application: ```bash # Run the OpenAPI-compatible server make ex-starwars ``` ```bash # Run Shiny make shiny ``` ![Screenshot of Star Wars shiny app demo](shiny/demo.png)
