# genai-toolbox: An MCP Server for Database-Driven AI Tools

genai-toolbox is an open-source MCP server, developed in Go, that streamlines the creation of AI agent tools designed to access and manipulate data within databases. It handles common complexities such as connection pooling and authentication, allowing developers to integrate database tools into their agents with significantly less boilerplate. Originally named "Gen AI Toolbox for Databases," it has been renamed to reflect its current MCP compatibility.

## Simplified Database Tool Development for Agents

The core value proposition of genai-toolbox lies in its ability to abstract away the intricacies of database interactions for AI agents. Developers can integrate tools into their agents using "less than 10 lines of code," fostering reusability across multiple agents or frameworks. This approach also simplifies the deployment of new tool versions. Beyond development ease, genai-toolbox incorporates best practices like connection pooling to enhance performance.

## Configuration with `tools.yaml`

Configuration of the genai-toolbox server is primarily managed through a `tools.yaml` file. If multiple configuration files are present, the `--tools-file tools.yaml` flag can specify which file to load. This configuration defines `sources`, `tools`, and `toolsets`.

### Defining Data Sources

The `sources` section within `tools.yaml` dictates which databases the Toolbox server can access. Most tools will require at least one defined source to execute against. For example, a PostgreSQL source can be configured as follows:

```yaml
sources:
  my-pg-source:
    kind: postgres
    host: 127.0.0.1
    port: 5432
    database: toolbox_db
    user: toolbox_user
    password: my-password
```

This snippet illustrates how to define a PostgreSQL database connection, specifying the host, port, database name, user, and password.

## Beta Status and Future Stability

It's important to note that genai-toolbox is currently in beta. As such, developers should anticipate potential breaking changes until its first stable release, designated as v1.0. This status implies that while the server is functional and useful, its API and internal architecture may evolve.
