### Description (declared)

# redshift-comment-mcp

**English** · [日本語](README.ja.md) · [繁體中文](README.zh-TW.md)

A read-only **Model Context Protocol** server for Amazon Redshift,
plus a Claude Code plugin with 6 slash-command skills built on top.
Designed around one assertion: **column names lie, comments don't**
— so the server exposes comments aggressively and the skills compose
those tools into the discovery workflows you actually do every day.

```
"What values does dbt_marts.fct_orders.status really hold?"
   → /redshift-profile dbt_marts.fct_orders status
   → cardinality, top-N, null rate, min/max, existing comment — one round.
```

## Why this exists

If you've ever opened an unfamiliar Redshift table and squinted at
column names like `f3`, `legacy_id_v2`, or `status` (which `status`?),
you already know the pain. dbt manifests are too narrow. Web GUIs
are too slow. Hand-written SQL is too repetitive.

This plugin's charter is **Guided Data Discovery**:

- **Comments first.** Every list / search tool returns the column,
  table, or schema comment when asked — names are advisory, comments
  are authoritative.
- **Read-only by construction.** `execute_sql` rejects DDL / DML at
  the parse layer; no skill in this repo can mutate Redshift.
- **MCP-composed skills.** New workflows are built by stringing
  together existing tools, not by adding new database connections.
- **No persistence.** No synthesis layer, no `.redshift-wiki/`
  markdown, no stale tracking. Persistence belongs in a separate plugin.

See [`implementation_guide.md`](implementation_guide.md) §1.2 for the
full charter.
