Go from an idea to a\nrunning, invocable tool in minutes, without ever leaving your terminal.\n\nLearn more about [Gemini CLI Extensions](https://github.com/google-gemini/gemini-cli/blob/main/docs/extensions/index.md).\n\u003e [!IMPORTANT]\n\u003e **We Want Your Feedback!**\n\u003e Please share your thoughts with us by filling out our feedback [form][form]. \n\u003e Your input is invaluable and helps us improve the project for everyone.\n\n[form]: https://docs.google.com/forms/d/e/1FAIpQLSfEGmLR46iipyNTgwTmIDJqzkAwDPXxbocpXpUbHXydiN1RTw/viewform?usp=pp_url\u0026entry.157487=mcp-toolbox\n\n## Why Use the MCP Toolbox Extension?\n\n* **Reliable Custom Servers:** Quickly create a **custom MCP server** with tools designed to reliably return accurate results. This saves significant development time and cost by ensuring your agent gets precise data without extensive guidance or fine-tuning.\n* **Enterprise Data Awareness:** Instantly upgrade your developer environment by providing your agents with **enterprise-grade data awareness**. Connect your AI systems directly to your data sources for smarter, more relevant operations.\n* **Accelerated Agent Development:** Fast-track your AI project by easily testing and validating tool usage with a **pre-built agent environment**.\n\n\n## Prerequisites\n\nBefore you begin, ensure you have the following:\n\n* [Gemini CLI](https://github.com/google-gemini/gemini-cli) installed with version **+v0.6.0**.\n* Setup Gemini CLI [Authentication](https://github.com/google-gemini/gemini-cli/tree/main?tab=readme-ov-file#-authentication-options).\n* Any required APIs and permissions for connecting to your database.\n\n## Getting Started\n\n### Installation\n\n```bash\ngemini extensions install https://github.com/gemini-cli-extensions/mcp-toolbox\n```\n\n### Configuration\n\n* Add your [`tools.yaml` configuration file](https://googleapis.github.io/genai-toolbox/getting-started/configure/) to the directory you\nare running Gemini CLI.\n\nEnsure [Application Default Credentials](https://cloud.google.com/docs/authentication/gcloud) are available in your environment if connecting to Google Cloud services.\n\n### Start Gemini CLI\n\nTo start the Gemini CLI, use the following command:\n\n```bash\ngemini\n```\n\n## Usage\n\nInteract with your custom tools using natural language.\n\n## Additional Extensions\n\nFind additional extensions to support your entire software development lifecycle at [github.com/gemini-cli-extensions](https://github.com/gemini-cli-extensions), including a generic [PostgreSQL extension](https://github.com/gemini-cli-extensions/postgres).\n\n## Troubleshooting\n\nUse `gemini --debug` to enable debugging.\n\nCommon issues:\n\n* \"failed to find default credentials: google: could not find default credentials.\": Ensure [Application Default Credentials](https://cloud.google.com/docs/authentication/gcloud) are available in your environment. See [Set up Application Default Credentials](https://cloud.google.com/docs/authentication/external/set-up-adc) for more information.\n* \"✖ Error during discovery for server: MCP error -32000: Connection closed\": The database connection has not been established. Ensure your configuration is set via environment variables.\n* \"✖ MCP ERROR: Error: spawn /Users/USER/.gemini/extensions/mcp-toolbox/toolbox ENOENT\": The Toolbox binary did not download correctly. Ensure you are using Gemini CLI v0.6.0+.\n* \"cannot execute binary file\": The Toolbox binary did not download correctly. Ensure the correct binary for your OS/Architecture has been downloaded. See [Installing the server](https://googleapis.github.io/genai-toolbox/getting-started/introduction/#installing-the-server) for more information.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgemini-cli-extensions%2Fmcp-toolbox","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgemini-cli-extensions%2Fmcp-toolbox","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgemini-cli-extensions%2Fmcp-toolbox/lists"}
