StarRocks Official MCP Server

The StarRocks MCP Server acts as a bridge between AI assistants and StarRocks databases. It allows for direct SQL execution, database exploration, data visualization via charts, and retrieving detailed schema/data overviews without requiring complex client-side setup.

Features

Direct SQL Execution: Run SELECT queries (read_query) and DDL/DML commands (write_query).
Database Exploration: List databases and tables, retrieve table schemas (starrocks:// resources).
System Information: Access internal StarRocks metrics and states via the proc:// resource path.
Detailed Overviews: Get comprehensive summaries of tables (table_overview) or entire databases (db_overview), including column definitions, row counts, and sample data.
Data Visualization: Execute a query and generate a Plotly chart directly from the results (query_and_plotly_chart).
Intelligent Caching: Table and database overviews are cached in memory to speed up repeated requests. Cache can be bypassed when needed.
Flexible Configuration: Set connection details and behavior via environment variables.

Prerequisites

Python 3.11 or newer.
A reachable StarRocks cluster (FE service). By default the server connects to localhost:9030 over the MySQL protocol.
uv — a fast Python package and project manager (a modern replacement for pip + virtualenv) from Astral. This project uses uv to resolve dependencies, create the virtual environment, and launch the server. The uv run commands throughout this README automatically create an isolated environment and install the required dependencies on first use, so no manual pip install step is needed.

Installing `uv`

# macOS / Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# Windows (PowerShell)
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

# Or via Homebrew / pipx / pip
brew install uv
# pipx install uv
# pip install uv

See the official uv installation guide for other options. After installing, verify it is on your PATH:

uv --version

Installation

You generally do not need to install the package manually — the MCP host launches it for you via uv (see Configuration below). uv fetches the package and its dependencies on demand.

To run it directly for testing or development:

# Run the published package in a throwaway environment
uv run --with mcp-server-starrocks mcp-server-starrocks --help

# Or, from a local checkout of this repository
git clone https://github.com/starrocks/mcp-server-starrocks.git
cd mcp-server-starrocks
uv sync                      # create the virtual environment and install dependencies
uv run mcp-server-starrocks --help

Configuration

The MCP server is typically run via an MCP host. Configuration is passed to the host, specifying how to launch the StarRocks MCP server process.

Using Streamable HTTP (recommended):

To start the server in Streamable HTTP mode:

First test that the connection to StarRocks is OK (9030 is the StarRocks MySQL protocol port, not the HTTP server port):

$ STARROCKS_URL=root:@localhost:9030 uv run mcp-server-starrocks --test

Start the server:

uv run mcp-server-starrocks --mode streamable-http --port 8000

Then config the MCP like this:

{
  "mcpServers": {
    "mcp-server-starrocks": {
      "url": "http://localhost:8000/mcp"
    }
  }
}

Using Docker:

Build the image:

docker build -t mcp-server-starrocks:local .

Build and push a versioned image:

docker build -t <registry>/<namespace>/mcp-starrocks:0.4.0 .
docker push <registry>/<namespace>/mcp-starrocks:0.4.0

Start the server in Streamable HTTP mode:

docker run --rm -p 8000:8000 \
  -e STARROCKS_HOST=host.docker.internal \
  -e STARROCKS_PORT=9030 \
  -e STARROCKS_USER=root \
  -e STARROCKS_PASSWORD='' \
  mcp-server-starrocks:local

Then configure the MCP client with:

{
  "mcpServers": {
    "mcp-server-starrocks": {
      "url": "http://localhost:8000/mcp"
    }
  }
}

Using uv with installed package (individual environment variables):

{
  "mcpServers": {
    "mcp-server-starrocks": {
      "command": "uv",
      "args": ["run", "--with", "mcp-server-starrocks", "mcp-server-starrocks"],
      "env": {
        "STARROCKS_HOST": "default localhost",
        "STARROCKS_PORT": "default 9030",
        "STARROCKS_USER": "default root",
        "STARROCKS_PASSWORD": "default empty",
        "STARROCKS_DB": "default empty"
      }
    }
  }
}

Using uv with installed package (connection URL):

{
  "mcpServers": {
    "mcp-server-starrocks": {
      "command": "uv",
      "args": ["run", "--with", "mcp-server-starrocks", "mcp-server-starrocks"],
      "env": {
        "STARROCKS_URL": "root:password@localhost:9030/my_database"
      }
    }
  }
}

Using uv with local directory (for development):

{
  "mcpServers": {
    "mcp-server-starrocks": {
      "command": "uv",
      "args": [
        "--directory",
        "path/to/mcp-server-starrocks", // <-- Update this path
        "run",
        "mcp-server-starrocks"
      ],
      "env": {
        "STARROCKS_HOST": "default localhost",
        "STARROCKS_PORT": "default 9030",
        "STARROCKS_USER": "default root",
        "STARROCKS_PASSWORD": "default empty",
        "STARROCKS_DB": "default empty"
      }
    }
  }
}

Using uv with local directory and connection URL:

{
  "mcpServers": {
    "mcp-server-starrocks": {
      "command": "uv",
      "args": [
        "--directory",
        "path/to/mcp-server-starrocks", // <-- Update this path
        "run",
        "mcp-server-starrocks"
      ],
      "env": {
        "STARROCKS_URL": "root:password@localhost:9030/my_database"
      }
    }
  }
}

Command-line Arguments:

The server supports the following command-line arguments:

uv run mcp-server-starrocks --help

--mode {stdio,sse,http,streamable-http}: Transport mode (default: stdio or MCP_TRANSPORT_MODE env var)
--host HOST: Server host for HTTP modes (default: localhost)
--port PORT: Server port for HTTP modes
--test: Run in test mode to verify functionality

Examples:

# Start in streamable HTTP mode on custom host/port
uv run mcp-server-starrocks --mode streamable-http --host 0.0.0.0 --port 8080

# Start in stdio mode (default)
uv run mcp-server-starrocks --mode stdio

# Run test mode
uv run mcp-server-starrocks --test

The url field should point to the Streamable HTTP endpoint of your MCP server (adjust host/port as needed).
With this configuration, clients can interact with the server using standard JSON over HTTP POST requests. No special SDK is required.
All tool APIs accept and return standard JSON as described above.

Note: The sse (Server-Sent Events) mode is deprecated and no longer maintained. Please use Streamable HTTP mode for all new integrations.

Environment Variables:

Connection Configuration

You can configure StarRocks connection using either individual environment variables or a single connection URL:

Option 1: Individual Environment Variables

STARROCKS_HOST: (Optional) Hostname or IP address of the StarRocks FE service. Defaults to localhost.
STARROCKS_PORT: (Optional) MySQL protocol port of the StarRocks FE service. Defaults to 9030.
STARROCKS_USER: (Optional) StarRocks username. Defaults to root.
STARROCKS_PASSWORD: (Optional) StarRocks password. Defaults to empty string.
STARROCKS_PASSWORD_FILE: (Optional) Path to a UTF-8 text file containing the password. This is useful with file-based secret injection such as systemd credentials. One trailing newline is ignored. This is only used when no explicit password is provided via STARROCKS_PASSWORD or STARROCKS_URL.
STARROCKS_PASSWORD_KEYCHAIN_SERVICE: (Optional, macOS only) Generic password service name to use when reading the password from Keychain. This is only used when no explicit password or STARROCKS_PASSWORD_FILE is configured.
STARROCKS_PASSWORD_KEYCHAIN_ACCOUNT: (Optional, macOS only) Generic password account name to use when reading the password from Keychain. Defaults to the resolved StarRocks user.
STARROCKS_DB: (Optional) Default database to use if not specified in tool arguments or resource URIs. If set, the connection will attempt to USE this database. Tools like table_overview and db_overview will use this if the database part is omitted in their arguments. Defaults to empty (no default database).
STARROCKS_QUERY_TIMEOUT: (Optional) Number of seconds to wait for a query's results before giving up, as an integer. Unset by default, which waits indefinitely, matching prior behavior. Set this if a stuck or long-running query should fail instead of blocking a tool call forever.

Option 2: Connection URL (takes precedence over individual variables)

STARROCKS_URL: (Optional) A connection URL string that contains all connection parameters in a single variable. Format: [<schema>://]user:password@host:port/database. The schema part is optional. When this variable is set, it takes precedence over the individual STARROCKS_HOST, STARROCKS_PORT, STARROCKS_USER, STARROCKS_PASSWORD, and STARROCKS_DB variables.

Examples:
- root:mypass@localhost:9030/test_db
- mysql://admin:[email protected]:9030/production
- starrocks://user:[email protected]:9030/analytics

Password precedence:

A password embedded in STARROCKS_URL wins, including an explicit empty password like user:@host:9030/db.
If STARROCKS_URL omits the password, STARROCKS_PASSWORD is used when set.
If neither explicit password source is set and STARROCKS_PASSWORD_FILE is configured, the password is read from that file.
If no explicit password or password file is configured and STARROCKS_PASSWORD_KEYCHAIN_SERVICE is set, the password is read from macOS Keychain.

macOS Keychain example

Store the password:

security add-generic-password -U -a root -s mcp-server-starrocks -w 'secret'

Verify the stored password:

security find-generic-password -a root -s mcp-server-starrocks -w

Use it with this server:

export STARROCKS_URL=root@localhost:9030/test_db
export STARROCKS_PASSWORD_KEYCHAIN_SERVICE=mcp-server-starrocks
export STARROCKS_PASSWORD_KEYCHAIN_ACCOUNT=root

systemd encrypted credentials example (systemd 250 or later)

The server does not invoke systemd-creds itself. At deployment time, an administrator encrypts the password; at service startup, systemd decrypts it into the service's credential directory and exposes only the file path to this server.

Create a host-bound encrypted credential without putting the password in shell history:

sudo -v
sudo install -d -m 0700 /etc/credstore.encrypted
sudo systemd-ask-password -n "StarRocks password:" \
  | sudo systemd-creds encrypt \
      --name=starrocks-password \
      - /etc/credstore.encrypted/starrocks-password.cred

Add the credential to the service unit. The %d specifier expands to the service-specific credential directory:

[Service]
LoadCredentialEncrypted=starrocks-password:/etc/credstore.encrypted/starrocks-password.cred
Environment=STARROCKS_PASSWORD_FILE=%d/starrocks-password
PrivateMounts=yes

Keep STARROCKS_PASSWORD unset and omit the password from STARROCKS_URL, then reload the unit and restart the service. The encrypted credential is normally bound to the local host (and to its TPM2 device when available); it is decrypted only while the service is being activated. The service process and administrators with root privileges can still access the plaintext password at runtime. Do not use systemd-creds encrypt --with-key=null, which does not provide confidentiality.

Additional Configuration

STARROCKS_FE_ARROW_FLIGHT_SQL_PORT: (Optional) Arrow Flight SQL port of the StarRocks FE service. When set, the server connects using the high-performance Arrow Flight SQL protocol (via ADBC drivers) instead of the standard MySQL protocol. Leave unset to use the default MySQL connection. The host, user, and password are taken from the same connection settings described above.
STARROCKS_OVERVIEW_LIMIT: (Optional) An approximate character limit for the total text generated by overview tools (table_overview, db_overview) when fetching data to populate the cache. This helps prevent excessive memory usage for very large schemas or numerous tables. Defaults to 20000.
STARROCKS_MCP_OUTPUT_DIR: (Optional) Directory used by read_query when its output_file argument is a relative path. Defaults to ~/.mcp-server-starrocks/output/. The directory is created on demand. Absolute paths passed to output_file (including ~-prefixed paths) bypass this setting. Note: files are written on the machine where the MCP server runs. For Claude Code / Claude Desktop the server runs locally, so files land on your laptop. For remote/http deployments the file lands on the server, not the client.
STARROCKS_CHART_OUTPUT_DIR: (Optional) Directory where query_and_plotly_chart writes interactive HTML charts (when format="html"). Defaults to the system temp directory. The directory is created on demand. Note: like other output files, charts are written on the machine where the MCP server runs.
STARROCKS_CHART_INCLUDE_PLOTLYJS: (Optional) Controls how plotly.js is bundled into HTML charts. cdn (default) keeps files small but needs network access when viewing; inline/true embeds the full library for offline use; directory and false are also accepted (passed through to Plotly's write_html).
STARROCKS_CHART_DEFAULT_FORMAT: (Optional) Default output format for query_and_plotly_chart when the format argument is omitted. One of json, png, jpeg (default), or html. Set to html to always write an interactive chart file to STARROCKS_CHART_OUTPUT_DIR (with an inline PNG preview) without passing on every call. Invalid values fall back to with a warning.

TLS / SSL Configuration

These variables control TLS for the connection. When none of them are set, the underlying mysql.connector keeps its default behavior (ssl-mode=PREFERRED): the connection is encrypted if the server supports TLS, but the server certificate is not verified. For real security, provide a CA certificate and enable verification.

STARROCKS_SSL_DISABLED: (Optional) Set to true to force-disable TLS. Overrides all other SSL settings. Defaults to false.
STARROCKS_SSL_CA: (Optional) Path to the CA certificate (PEM) used to verify the StarRocks server certificate.
STARROCKS_SSL_CERT: (Optional) Path to the client certificate (PEM) for mutual TLS (mTLS).
STARROCKS_SSL_KEY: (Optional) Path to the client private key (PEM) for mutual TLS (mTLS).
STARROCKS_SSL_VERIFY_CERT: (Optional) Set to true to verify the server certificate against the CA. Defaults to false.
STARROCKS_SSL_VERIFY_IDENTITY: (Optional) Set to true to also verify that the server hostname matches the certificate. Defaults to false.
STARROCKS_TLS_VERSIONS: (Optional) Comma-separated list of allowed TLS versions, e.g. TLSv1.2,TLSv1.3.

Example (verify the server against a CA certificate):

"env": {
  "STARROCKS_HOST": "your-fe-host",
  "STARROCKS_PORT": "9030",
  "STARROCKS_USER": "root",
  "STARROCKS_PASSWORD": "your-password",
  "STARROCKS_SSL_CA": "/path/to/ca.pem",
  "STARROCKS_SSL_VERIFY_CERT": "true",
  "STARROCKS_SSL_VERIFY_IDENTITY": "true"
}

For the high-performance Arrow Flight SQL connection (enabled via STARROCKS_FE_ARROW_FLIGHT_SQL_PORT), TLS is controlled separately:

STARROCKS_FE_ARROW_FLIGHT_SQL_USE_TLS: (Optional) Set to true to use grpc+tls:// instead of plaintext grpc://. When enabled, STARROCKS_SSL_CA is used as the TLS root certificate and STARROCKS_SSL_VERIFY_CERT=false (default) skips server certificate verification.

Security note: avoid storing plaintext passwords directly in mcp.json. Prefer injecting STARROCKS_PASSWORD (and certificate paths) from a secrets manager or environment, and never commit credentials to version control.

MCP_TRANSPORT_MODE: (Optional) Communication mode that specifies how the MCP Server exposes its services. Available options:
- stdio (default): Communicates through standard input/output, suitable for MCP Host hosting.
- streamable-http (Streamable HTTP): Starts as a Streamable HTTP Server, supporting RESTful API calls.
- sse: (Deprecated, not recommended) Starts in Server-Sent Events (SSE) streaming mode, suitable for scenarios requiring streaming responses. Note: SSE mode is no longer maintained, it is recommended to use Streamable HTTP mode uniformly.

Components

Tools

read_query
- Description: Execute a SELECT query or other commands that return a ResultSet (e.g., SHOW, DESCRIBE). Optionally write the full result to a local file instead of returning it inline — useful for results too large to fit in the model context.
- Input:
```
{
  "query": "SQL query string",
  "db": "database name (optional, uses default database if not specified)",
  "output_file": "optional path; if set, writes the full result to disk and returns only a summary + small preview. Relative paths resolve against STARROCKS_MCP_OUTPUT_DIR (default: ~/.mcp-server-starrocks/output/); absolute paths and ~ are used as-is",
  "output_format": "optional: csv | tsv | json | jsonl. If omitted, inferred from output_file extension (.csv/.tsv/.json/.jsonl/.ndjson); defaults to csv"
}
```
- Output: Without output_file, text content containing the query results in CSV-like format with a header row and row count summary. With output_file, a short summary including the resolved absolute path, byte count, and row count, plus a small preview. Returns an error message on failure.
write_query
- Description: Execute a DDL (CREATE, ALTER, DROP), DML (INSERT, UPDATE, DELETE), or other StarRocks command that does not return a ResultSet.
- Input:
```
{
  "query": "SQL command string",
  "db": "database name (optional, uses default database if not specified)"
}
```
- Output: Text content confirming success (e.g., "Query OK, X rows affected") or reporting an error. Changes are committed automatically on success.
analyze_query
- Description: Analyze a query and get analyze result using query profile or explain analyze.
- Input:
```
{
  "uuid": "Query ID, a string composed of 32 hexadecimal digits formatted as 8-4-4-4-12",
  "sql": "Query SQL to analyze",
  "db": "database name (optional, uses default database if not specified)"
}
```
- Output: Text content containing the query analysis results. Uses ANALYZE PROFILE FROM if uuid is provided, otherwise uses EXPLAIN ANALYZE if sql is provided.

Caching Behavior

The table_overview and db_overview tools utilize an in-memory cache to store the generated overview text.
The cache key is a tuple of (database_name, table_name).
When table_overview is called, it checks the cache first. If a result exists and the refresh parameter is false (default), the cached result is returned immediately. Otherwise, it fetches the data from StarRocks, stores it in the cache, and then returns it.
When db_overview is called, it lists all tables in the database and then attempts to retrieve the overview for each table using the same caching logic as table_overview (checking cache first, fetching if needed and refresh is false or cache miss). If refresh is true for db_overview, it forces a refresh for all tables in that database.
The STARROCKS_OVERVIEW_LIMIT environment variable provides a soft target for the maximum length of the overview string generated per table when populating the cache, helping to manage memory usage.
Cached results, including any error messages encountered during the original fetch, are stored and returned on subsequent cache hits.
