It is crucial to set up the necessary roles and policies in your cloud environment (e.g., AWS) and link them correctly within Confluent Cloud. This ensures your Flink SQL cluster, which powers Tableflow, has the required authorization to perform operations on your behalf. Please refer to the following Confluent Cloud documentation for detailed instructions on setting up these permissions and integrating with custom storage and Glue: * **Confluent Cloud Tableflow Quick Start with Custom Storage & Glue:** [https://docs.confluent.io/cloud/current/topics/tableflow/get-started/quick-start-custom-storage-glue.html](https://docs.confluent.io/cloud/current/topics/tableflow/get-started/quick-start-custom-storage-glue.html) Ensuring these prerequisites are met will prevent authorization errors when the `mcp-server` attempts to provision or manage Tableflow-enabled tables. ### Environment Variables Reference | Variable | Description | Default Value | Required | | ----------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------- | ------------- | -------- | | HTTP_HOST | Host to bind for HTTP transport (string) | "localhost" | Yes | | HTTP_PORT | Port to use for HTTP transport (number (min: 0)) | 3000 | Yes | | LOG_LEVEL | Log level for application logging (trace, debug, info, warn, error, fatal) (effects) | "info" | Yes | | BOOTSTRAP_SERVERS | List of Kafka broker addresses in the format host1:port1,host2:port2 used to establish initial connection to the Kafka cluster (string) | | No | | CONFLUENT_CLOUD_API_KEY | Master API key for Confluent Cloud platform administration, enabling management of resources across your organization (string (min: 1)) | | No | | CONFLUENT_CLOUD_API_SECRET | Master API secret paired with CONFLUENT_CLOUD_API_KEY for comprehensive Confluent Cloud platform administration (string (min: 1)) | | No | | CONFLUENT_CLOUD_REST_ENDPOINT | Base URL for Confluent Cloud's REST API services (default) | | No | | FLINK_API_KEY | Authentication key for accessing Confluent Cloud's Flink services, including compute pools and SQL statement management (string (min: 1)) | | No | | FLINK_API_SECRET | Secret token paired with FLINK_API_KEY for authenticated access to Confluent Cloud's Flink services (string (min: 1)) | | No | | FLINK_COMPUTE_POOL_ID | Unique identifier for the Flink compute pool, must start with 'lfcp-' prefix (string) | | No | | FLINK_DATABASE_NAME | Name of the associated Kafka cluster used as a database reference in Flink SQL operations (string (min: 1)) | | No | | FLINK_ENV_ID | Unique identifier for the Flink environment, must start with 'env-' prefix (string) | | No | | FLINK_ENV_NAME | Human-readable name for the Flink environment used for identification and display purposes (string (min: 1)) | | No | | FLINK_ORG_ID | Organization identifier within Confluent Cloud for Flink resource management (string (min: 1)) | | No | | FLINK_REST_ENDPOINT | Base URL for Confluent Cloud's Flink REST API endpoints used for SQL statement and compute pool management (string) | | No | | KAFKA_API_KEY | Authentication credential (username) required to establish secure connection with the Kafka cluster (string (min: 1)) | | No | | KAFKA_API_SECRET | Authentication credential (password) paired with KAFKA_API_KEY for secure Kafka cluster access (string (min: 1)) | | No | | KAFKA_CLUSTER_ID | Unique identifier for the Kafka cluster within Confluent Cloud ecosystem (string (min: 1)) | | No | | KAFKA_ENV_ID | Environment identifier for Kafka cluster, must start with 'env-' prefix (string) | | No | | KAFKA_REST_ENDPOINT | REST API endpoint for Kafka cluster management and administration (string) | | No | | SCHEMA_REGISTRY_API_KEY | Authentication key for accessing Schema Registry services to manage and validate data schemas (string (min: 1)) | | No | | SCHEMA_REGISTRY_API_SECRET | Authentication secret paired with SCHEMA_REGISTRY_API_KEY for secure Schema Registry access (string (min: 1)) | | No | | SCHEMA_REGISTRY_ENDPOINT | URL endpoint for accessing Schema Registry services to manage data schemas (string) | | No | | TABLEFLOW_API_KEY | Authentication key for accessing Confluent Cloud's Tableflow services (string (min: 1)) | | No | | TABLEFLOW_API_SECRET | Authentication secret paired with TABLEFLOW_API_KEY for secure Tableflow access (string (min: 1)) | | No | ### Usage This MCP server is designed to be used with various MCP clients, such as Claude Desktop or Goose CLI/Desktop. The specific configuration and interaction will depend on the client you are using. However, the general steps are: 1. **Start the Server:** You can run the MCP server in one of two ways: - **From source:** Follow the instructions in the [Developer Guide](#developer-guide) to build and run the server from source. This typically involves: - Installing dependencies (`npm install`) - Building the project (`npm run build` or `npm run dev`) - **With npx:** You can start the server directly using npx (no build required): ```bash npx -y @confluentinc/mcp-confluent -e /path/to/confluent-mcp-server/.env ``` 2. **Configure your MCP Client:** Each client will have its own way of specifying the MCP server's address and any required credentials. You'll need to configure your client (e.g., Claude, Goose) to connect to the address where this server is running (likely `localhost` with a specific port). The port the server runs on may be configured by an environment variable. 3. **Start the MCP Client:** Once your client is configured to connect to the MCP server, you can start your mcp client and on startup - it will stand up an instance of this MCP server locally. This instance will be responsible for managing data schemas and interacting with Confluent Cloud on your behalf. 4. **Interact with Confluent through the Client:** Once the client is connected, you can use the client's interface to interact with Confluent Cloud resources. The client will send requests to this MCP server, which will then interact with Confluent Cloud on your behalf. ### Configuring Claude Desktop See [here](https://modelcontextprotocol.io/quickstart/user) for more details about installing Claude Desktop and MCP servers. To configure Claude Desktop to use this MCP server: 1. **Open Claude Desktop Configuration** - On Mac: `~/Library/Application Support/Claude/claude_desktop_config.json` - On Windows: `%APPDATA%\Claude\claude_desktop_config.json` 2. **Edit Configuration File** - Open the config file in your preferred text editor - Add or modify the configuration using one of the following methods: <details> <summary>Option 1: Run from source</summary> ```json { "mcpServers": { "confluent": { "command": "node", "args": [ "/path/to/confluent-mcp-server/dist/index.js", "--env-file", "/path/to/confluent-mcp-server/.env", ] } } } ``` </details> <details> <summary>Option 2: Run from npx</summary> ```json { "mcpServers": { "confluent": { "command": "npx", "args": [ "-y" "@confluentinc/mcp-confluent", "-e", "/path/to/confluent-mcp-server/.env" ] } } } ``` </details> Replace `/path/to/confluent-mcp-server/` with the actual path where you've installed this MCP server. 1. **Restart Claude Desktop** - Close and reopen Claude Desktop for the changes to take effect - The MCP server will automatically start when Claude Desktop launches Now Claude Desktop will be configured to use your local MCP server for Confluent interactions.  ### Configuring Goose CLI See [here](https://block.github.io/goose/docs/quickstart#install-an-extension) for detailed instructions on how to install the Goose CLI. Once installed, follow these steps: 1. **Run the Configuration Command:** ```bash goose configure ``` 2. **Follow the Interactive Prompts:** - Select `Add extension` - Choose `Command-line Extension` - Enter `mcp-confluent` as the extension name - Choose one of the following configuration methods: <details> <summary>Option 1: Run from source</summary> ```bash node /path/to/confluent-mcp-server/dist/index.js --env-file /path/to/confluent-mcp-server/.env ``` </details> <details> <summary>Option 2: Run from npx</summary> ```bash npx -y @confluentinc/mcp-confluent -e /path/to/confluent-mcp-server/.env ``` </details> Replace `/path/to/confluent-mcp-server/` with the actual path where you've installed this MCP server.  ### mcp-confluent CLI Usage The MCP server provides a flexible command line interface (CLI) for advanced configuration and control. The CLI allows you to specify environment files, transports, and fine-tune which tools are enabled or blocked. #### Basic Usage You can view all CLI options and help with: ```bash npx @confluentinc/mcp-confluent --help ``` <details> <summary>Show output</summary> ```bash Usage: mcp-confluent [options] Confluent MCP Server - Model Context Protocol implementation for Confluent Cloud Options: -V, --version output the version number -e, --env-file <path> Load environment variables from file -k, --kafka-config-file <file> Path to a properties file for configuring kafka clients -t, --transport <types> Transport types (comma-separated list) (choices: "http", "sse", "stdio", default: "stdio") --allow-tools <tools> Comma-separated list of tool names to allow.

These should be provided in the `.env` file in the root directory of this project. Or you can add them directly in the `docker-compose.yml` #### Building and Running with Docker Here's how to build your Docker image and run it in different modes. 1. **Navigate to your project directory.** Open your terminal or command prompt and change to the directory containing the `Dockerfile`. ```bash cd /path/to/repo/mcp-confluent ``` 2. **Build the Docker image.** This command creates the `mcp-server` image based on the `Dockerfile` in the current directory. ```bash docker build -t mcp-server . ``` 3. **Run the container** * `--rm`: **Automatically removes the container** when it exits. This helps keep your system clean. * `-i`: Keeps **STDIN open** (runs the server using stdio transport by default). * `-d`: Runs the container in **detached mode** (in the background). * `-p 3000:3000`: **Maps port 3000** on your host machine to port 3000 inside the container. Adjust this if your app listens on a different port. ```bash docker run --rm -i -d -p 3000:3000 mcp-server ``` (Optional) * `-t` **Transport Mode** to enable http transport ```bash docker run --rm -d -p 3000:3000 mcp-server -t http ``` #### Building and Running with Docker Compose 1. **Navigate to the project root:** Open your terminal or command prompt and change to the directory containing Dockerfile and docker-compose.yml. ```bash cd /path/to/repo/mcp-confluent ``` 2. **Build and run the service:** Docker Compose will build the Docker image (if not already built) and start the mcp-server service. ```bash docker compose up --build ``` The --build flag ensures that Docker Compose rebuilds the image before starting the container. You can omit this flag on subsequent runs if you haven't changed the Dockerfile or source code. The server will be accessible on http://localhost:3000 (or the port specified in HTTP_PORT in your .env file). 3. **Stopping the Server** To stop the running MCP server and remove the containers, press Ctrl+C in the terminal where docker compose up is running. Alternatively, in a new terminal from the project root, you can run: ```bash docker compose down ``` This command stops and removes the containers, networks, and volumes created by docker compose up. ### Testing #### MCP Inspector For testing MCP servers, you can use [MCP Inspector](https://modelcontextprotocol.io/docs/tools/inspector) which is an interactive developer tool for testing and debugging MCP servers. ```bash # make sure you've already built the project either in dev mode or by running npm run build npx @modelcontextprotocol/inspector node $PATH_TO_PROJECT/dist/index.js --env-file $PATH_TO_PROJECT/.env ``` ### Adding a New Tool 1. Add a new enum to the enum class `ToolName`. 2. Add your new tool to the handlers map in the `ToolFactory` class. 3. Create a new file, exporting the class that extends `BaseToolHandler`. 1. Implement the `handle` method of the base class. 2. Implement the `getToolConfig` method of the base class. 4. Once satisfied, add it to the set of `enabledTools` in `index.ts`. ### Generating Types ```bash # as of v7.5.2 there is a bug when using allOf w/ required https://github.com/openapi-ts/openapi-typescript/issues/1474. need --empty-objects-unknown flag to avoid it npx openapi-typescript ./openapi.json -o ./src/confluent/openapi-schema.d.ts --empty-objects-unknown ``` ### Contributing Bug reports and feedback is appreciated in the form of Github Issues.
