:: see releases page for other versions
set VERSION=1.2.0
curl -o toolbox.exe "https://storage.googleapis.com/mcp-toolbox-for-databases/v%VERSION%/windows/amd64/toolbox.exe"

Windows (PowerShell)

To install Toolbox as a binary on Windows (PowerShell):

# see releases page for other versions
$VERSION = "1.2.0"
curl.exe -o toolbox.exe "https://storage.googleapis.com/mcp-toolbox-for-databases/v$VERSION/windows/amd64/toolbox.exe"

# see releases page for other versions
export VERSION=1.2.0
docker pull us-central1-docker.pkg.dev/database-toolbox/toolbox/toolbox:$VERSION

To install Toolbox using Homebrew on macOS or Linux:

brew install mcp-toolbox

To install from source, ensure you have the latest version of Go installed, and then run the following command:

go install github.com/googleapis/mcp-toolbox@v1.2.0

# Install Gemini CLI
npm install -g @google/gemini-cli
# Install the extension
gemini extensions install https://github.com/gemini-cli-extensions/cloud-sql-postgres
# Run Gemini CLI
gemini

Interact with your custom tools using natural language through the Gemini CLI.

# Install the extension
gemini extensions install https://github.com/gemini-cli-extensions/mcp-toolbox

To run Toolbox from binary:

./toolbox --config "tools.yaml"

ⓘ Note
Toolbox enables dynamic reloading by default. To disable, use the --disable-reload flag.

To run the server after pulling the container image:

export VERSION=0.24.0 # Use the version you pulled
docker run -p 5000:5000 \
-v $(pwd)/tools.yaml:/app/tools.yaml \
us-central1-docker.pkg.dev/database-toolbox/toolbox/toolbox:$VERSION \
--config "/app/tools.yaml"

ⓘ Note
The -v flag mounts your local tools.yaml into the container, and -p maps the container's port 5000 to your host's port 5000.

To run the server directly from source, navigate to the project root directory and run:

go run .

ⓘ Note
This command runs the project from source, and is more suitable for development and testing. It does not compile a binary into your $GOPATH. If you want to compile a binary instead, refer the Developer Documentation.

If you installed Toolbox using Homebrew, the toolbox binary is available in your system path. You can start the server with the same command:

toolbox --config "tools.yaml"

To run Toolbox directly without manually downloading the binary (requires Node.js):

npx @toolbox-sdk/server --config tools.yaml

# Run Gemini CLI
gemini

# List extensions
/extensions list
# List MCP servers
/mcp list
