amx-cli 0.19.0

Cryptic columns, reviewed comments.

AMX walks your database, reads your codebase and docs, then drafts a COMMENT for every table, view, and column — with confidence scores and a human review before anything lands in the live database.

Documentation · Quickstart · Changelog · Issues

AMX is in early development — expect breaking changes between releases. Stay current with pip install --upgrade amx-cli.

Three independent sub-agents — Profile (schema, stats, sample values), RAG (ingested docs), and Code (references mined from your repos) — gather evidence in parallel. An orchestrator merges and ranks them, you accept / edit / skip each suggestion, and AMX writes the approved text back as native COMMENT statements on the engine.

Five minutes from pip install to your first reviewed comment. Ten database engines, seven LLM providers.

Install

pip install amx-cli

The PyPI distribution is amx-cli; the import package is amx (import amx). Requires Python 3.10+. See the installation guide for prerequisites, source builds, and where AMX writes config / history / logs.

Quick start

amx                       # open the interactive session (the AMX REPL)
/setup                    # one-time wizard: DB profile + LLM profile
/connect                  # sanity-check the active connection
/run sales.orders         # generate suggestions, review, accept
/apply                    # write approved descriptions back to the database

/run without an argument opens a scope picker (Database / Schema / Asset). /run-apply short-circuits review-and-apply when you already trust the model. If anything misbehaves, amx doctor runs from any shell — even when AMX itself can't start — and prints actionable hints next to each ✗.

The full guided walkthrough is at the 5-minute quickstart and first-run walkthrough.

AMX CLI

A typical session — running /run, inspecting ranked suggestions inline, accepting or editing each one before it lands in the database.

AMX Studio (/studio) — same workflow on a local web UI

From inside the REPL, /studio boots AMX Studio, a token-protected web UI on 127.0.0.1, and opens your browser. Same review-and-apply workflow as the REPL — runs, results, the pending queue, the /ask chat, and full DB / LLM / Docs / Code profile management — but on a denser surface. Browse any database / schema / table to inline-edit comments or hit per-asset Generate to draft just one comment through the same human-in-the-loop queue. The SPA bundle ships inside amx-cli; no Node toolchain or extra install needed.

Full walkthrough at /studio.

How it works

Each agent runs independently, surfaces its own evidence, and assigns its own confidence. The orchestrator picks the narrower, defensible description and ranks up to N alternatives. You never apply anything you didn't approve.

A column, before and after

A typical column in orders, the kind every analytics codebase has:

orders.shipped_dt   DATE   NULL   -- (no comment)

What AMX produces, after you approve:

COMMENT ON COLUMN orders.shipped_dt IS
  'Date the carrier scanned the package at origin. Distinct from
   order_dt (when the customer placed the order) and delivered_dt
   (when the carrier recorded proof of delivery).';

confidence: high · logprob: 0.91
sources: code (3 refs) · docs · db profile

Every approval is recorded in local run history — re-evaluate later with /history review to see how the same column scores under a different model, prompt detail, or evidence mix.

Supported database backends

PostgreSQL · Snowflake · Databricks (Unity Catalog) · BigQuery · MySQL / MariaDB · Oracle · SQL Server · Redshift · ClickHouse · DuckDB

Per-backend setup, connection details, and the capability matrix live in the Backends section.

Supported LLM providers

OpenAI · Anthropic · Google Gemini · DeepSeek · OpenRouter · Ollama · vLLM / LM Studio · any OpenAI-compatible endpoint

Provider-specific guides (including OpenAI / Anthropic Batch mode and local-model setups) live in the LLM providers section.

Next up

• dbt integration — Connect dbt projects so the AMX code agent extracts table and column metadata from the transformation layer.
• MCP integration for docs and repo — Expose the AMX repo and docs over the Model Context Protocol so LLM clients can query them as live context.
• CDC integration — Detect schema changes in upstream sources and keep AMX metadata in sync.

See the full roadmap for details.
