Available tools

File System Tool

A file system tool that supports reading, writing, deleting and listing files.

curl -X POST "http://localhost:8000/tools/file_operations" \
     -H "Content-Type: application/json" \
     -d '{"operation": "list", "path": "."}'

Weather Tool

A tool for obtaining weather data by coordinates.

curl -X POST "http://localhost:8000/tools/weather" \
     -H "Content-Type: application/json" \
     -d '{"latitude": 37.7749, "longitude": -122.4194}'

Text Analysis Tool

A tool for text analysis, including sentiment detection and summarization.

curl -X POST "http://localhost:8000/tools/text_analysis" \
     -H "Content-Type: application/json" \
     -d '{"text": "Example text for analysis", "analysis_type": "sentiment"}'

Text Processor Tool

A tool for text processing, including formatting, statistics calculation, entity extraction.

curl -X POST "http://localhost:8000/tools/text_processor" \
     -H "Content-Type: application/json" \
     -d '{"operation": "statistics", "text": "Example text", "stat_options": ["chars", "words"]}'

Image Processing Tool

An image processing tool that supports resizing, cropping and applying filters.

curl -X POST "http://localhost:8000/tools/image_processing" \
     -H "Content-Type: application/json" \
     -d '{"operation": "resize", "image_data": "base64...", "params": {"width": 800, "height": 600}}'

WebSocket API

To connect to the WebSocket API:

const socket = new WebSocket("ws://localhost:8000/ws");

socket.onopen = () => {
  socket.send(JSON.stringify({
    type: "initialize",
    id: "my-request-id"
  }));
};

socket.onmessage = (event) => {
  const data = JSON.parse(event.data);
  console.log("Received:", data);
};

GraphQL API

Examples of queries via GraphQL:

# Получение списка всех инструментов
query {
  getTools {
    name
    description
  }
}

# Выполнение инструмента
mutation {
  executeTool(input: {
    name: "text_processor",
    parameters: {
      operation: "statistics",
      text: "Example text for analysis"
    }
  }) {
    content {
      type
      text
    }
    is_error
  }
}

Running tests

To run tests, use Poetry:

poetry run pytest

docker compose up -d web redis elasticsearch

Integration with LLM

MCP Server provides a standardized interface for integration with LLM models from various vendors:

import httpx

async def query_mcp_with_llm(prompt: str):
    async with httpx.AsyncClient() as client:
        # Запрос к MCP для получения контекста и инструментов
        tools_response = await client.get("http://localhost:8000/tools")
        tools = tools_response.json()["tools"]

        # Отправка запроса к LLM с включением MCP контекста
        llm_response = await client.post(
            "https://api.example-llm.com/v1/chat",
            json={
                "messages": [
                    {"role": "system", "content": "You have access to the following tools:"},
                    {"role": "user", "content": prompt}
                ],
                "tools": tools,
                "tool_choice": "auto"
            }
        )

        return llm_response.json()

Metrics and monitoring

MCP Server provides metrics in Prometheus format via the /metrics endpoint. Metrics include:

Number of requests to each tool
Query execution time
Errors and exceptions

Development

To format code and check it with linters:

just fmt
just lint
