Jarroba Tools

What Jarroba Tools MCP server does

Jarroba Tools MCP server provides a collection of deterministic tools for AI agents running on a developer’s machine. The available areas named in the project description are logs, tests, SQL, diagrams, and SPARQL, with 134 tools in total. These capabilities place the project in the 💻 Developer Tools category and make it relevant for agents that need repeatable local operations rather than remote service access.

The repository is the source mirror for the @jarroba/mcp family of MCP servers. Its implementation reuses the engines behind the tools available at jarroba.com/tools. The same engine layout is used in the web application and in this codebase, with the relevant source located under src/app/.

How it works

Jarroba Tools MCP server runs its tools on the local machine. The project states that the tools upload nothing, and the current description identifies them as local and usable without network access. This makes the server suitable for workflows where an agent should process logs, execute testing-related utilities, work with SQL, create diagrams, or handle SPARQL locally.

The package is part of a family of MCP servers rather than a single-purpose connector. The provided material does not specify individual tool names, request schemas, supported database engines, diagram formats, SPARQL endpoints, or the MCP transport used at runtime. Those details should be verified in the package documentation before building an integration around a specific operation.

Setup and configuration

To install the repository’s dependencies and run its build and test checks, use the commands documented by the project:

npm install
cd mcp && npm install
npm run build && npm test && npm run test:paquete

The first command installs the root engine dependencies. The second installs dependencies in the mcp directory. The remaining commands build the MCP packages, run the test suite, and run the package-specific test command. The supplied material does not list environment variables or additional runtime configuration.

Tools and capabilities

Jarroba Tools MCP server is described as offering 134 deterministic tools across these areas:

• Log-related operations
• Test-related operations
• SQL operations
• Diagram-related operations
• SPARQL operations

The description establishes the tool categories and local execution model, but it does not define the exact inputs, outputs, side effects, or prerequisites for each category. Consult the documentation in mcp/ when selecting a particular tool.

Limitations and notes

The public repository is a read-only mirror generated from a private Jarroba Tools repository at each release. Issues can be submitted, but pull requests cannot be merged into this mirror. Third-party notices are included in each package’s dist/ directory. The project is licensed under MIT.

Because the available material does not name specific MCP clients, transport modes, operating-system requirements, or per-tool dependencies, client compatibility and deployment details cannot be confirmed from this listing alone.
