# Quickstart - Adding Observability and Analytics to MCPs using Logger SDK

## 1. Installation

<CodeGroup>
  ```bash Python theme={null}
  pip install mcp-logger
  ```

  ```bash TypeScript theme={null}
  npm install @observee/logger
  ```
</CodeGroup>

## 2. Initialize the SDK within your main MCP server file

If you are an enterprise or an individual developer with an API key, you can pass it to the logger. This will enable you to see all input and response data from tools and prompts.

<CodeGroup>
  ```python Python theme={null}
  from observee import ObserveeConfig, observee_usage_logger, observee_prompt_logger

  # Set the MCP server name globally
  ObserveeConfig.set_mcp_server_name("your-mcp-server-name")

  # Optionally, if you have an API key, you can pass it to the logger.
  ObserveeConfig.set_api_key("your-api-key")
  ```

  ```typescript TypeScript theme={null}

  import { Logger, observeeUsageLogger } from "@observee/sdk";

  const loggerWithAPIKey = new Logger("your-mcp-server-name", {
      apiKey: "your-api-key", 
  });

  const loggerNoAPIKey = new Logger("your-mcp-server-name");
  ```
</CodeGroup>

## 3. Add logging to tool calls.

In Python, you can add it to each individual tool call, or you can use the `observee_usage_logger` decorator to log all tool calls.

<CodeGroup>
  ```python Python theme={null}
  @observee_usage_logger
  async def your_tool_function():
      # Your tool code here
      pass
  ```

  ```typescript TypeScript theme={null}
  server.setRequestHandler(
    CallToolRequestSchema,
    observeeUsageLogger(logger, async (request) => {
      // your handler code here
    }))
  ```
</CodeGroup>

## 4. Add logging to your prompt calls.

<CodeGroup>
  ```python Python theme={null}
  @observee_prompt_logger
  async def your_prompt_function():
      # Your prompt code here
      pass
  ```

  ```typescript TypeScript theme={null}
  server.setRequestHandler(
    GetPromptRequestSchema,
    observeeUsageLogger(logger, async (request) => {
      // your handler code here
    }))
  ```
</CodeGroup>
