Jarroba Tools runs on your own machine — the client starts it, so there is no endpoint to ping. 672 installs a week from npm.
100 deterministic tools for your AI: logs, tests, SQL, diagrams, SPARQL. Local, no network.
The linked repository no longer exists on GitHub — it was deleted or made private.
Quiet is not dead — but it is worth knowing when it wakes up, or when someone else takes it over. We watch the repository and tell you either way.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
JARROBA_MCP_DOMAINS (Which tool domains to publish, comma-separated. Defaults to what this package is for. Valid: core, calc, diagram, kg, db, ai, logs, queue, project, tests, api, chip, chem. Fewer domains means less of your context window spent on tool definitions.).
The author declared them in the registry entry; get the values from the project itself.
Deterministic SQL compiler for AI agents. Your agent stops guessing SQL.
Local-first memory for AI agents: SQLite FTS5, deterministic recall, no vector DB, no cloud.
Persistent session memory for Claude Code. Local SQLite, no LLMs, no network.
Task queue, decisions and memory for coding agents. Local SQLite, no network. Requires Bun.
Local-first graph memory for AI assistants with SQLite, semantic search, and MCP tools.
Deterministic safety, correctness & cost gate that vets Postgres SQL before your AI agent runs it.
Local memory for AI agents. One SQLite file on your machine — no cloud, no account.
Deterministic validation for AI-generated artifacts: JSON Schema, OpenAPI response, SQL syntax.
