在上方选择你的应用。我们会记住它，下次按钮会显示“安装到 …”。

打开 Claude Desktop → Settings → Developer → Edit Config，把下面的内容粘贴到 claude_desktop_config.json

{
  "mcpServers": {
    "codedb-lens": {
      "command": "docker",
      "args": [
        "run",

      ],
      "env": {
        "CODEDB_LENS_PASSWORD": "your-value"
      }
    }
  }
}

在终端中运行这条命令

claude mcp add codedb-lens --env CODEDB_LENS_PASSWORD=your-value -- docker run -i --rm -e CODEDB_LENS_PASSWORD ghcr.io/codedb-io/codedb-lens:0.9.1 mcp --engine your-value --server your-value

运行前请先填写空着的值。

这个服务器需要在启动命令中填入值，请复制设置后自行填写。

或者自己复制设置

粘贴到项目中的 .cursor/mcp.json，或 ~/.cursor/mcp.json

      "env": {
        "CODEDB_LENS_PASSWORD": "your-value"
      }
    }
  }
}

浏览器会先询问是否打开应用，然后应用会显示设置并请你确认。密钥的值会留空，由你自己填写。

See what your database isn't showing you.

Free, read-only health check for SQL Server and PostgreSQL .

Website · English · Português (Brasil)

Real run against a test SQL Server (host renamed). Open a demo report .

v0.8: check (with an executive summary and --redact for sharing), compare, and record + report to watch an instance for up to 24 hours (how). 26 rules plus 8 for recordings. FAQ and more on the website.

codeDB Lens connects to your instance with a read-only login, runs a catalog of evidence-based rules and writes a self-contained HTML + JSON report with an A–F grade and a coverage seal (the share of rules that could actually run). Nothing about your database leaves your machine.

Install

Where	How
Windows	Installer (per user, no admin) or portable .zip
Windows (Scoop)	`scoop bucket add codedb https://github.com/codedb-io/codedb-lens` then `scoop install codedb/codedb-lens`
Linux	`.deb` / `.rpm` from the latest release, or the tarball for x64 / arm64
Docker	`docker run --rm -e PG_DSN -v "$PWD:/out" ghcr.io/codedb-io/codedb-lens check --engine pg --dsn-env PG_DSN --out /out`

The Windows binaries are open source but not code-signed yet, so SmartScreen may show a warning. Why, and how to verify the download.

Why another tool?

Evidence, not opinions. Every finding shows the collected values, the query that produced them and when.
Honest confidence. Each finding is *Confirmed*, *Hint* or *No data*. A rule that lacks permission never shows up as a false "OK"; it lowers the coverage instead.
Read-only, always. No DDL, no DML, no agent, no installation on the server.
Rules are data. Each rule is a YAML file plus a SQL query. Contributions don't touch the engine.
English and Portuguese (Brazil), in the app, the CLI and the report.

What it checks

SQL Server	PostgreSQL
Missing or old backups	Version out of support
No recent clean DBCC CHECKDB	pg_stat_statements not available
Failing SQL Agent jobs	A single query dominating execution time
Disk or transaction log running out of space	Long and idle-in-transaction sessions
Dominant waits, translated	Sessions blocked by locks
Sessions blocked right now	Transaction ID wraparound risk
A single query dominating CPU	Dead rows and autovacuum falling behind
Instance settings left at defaults	Replication slots retaining WAL, replica lag
TempDB file layout	Connections near the limit, no pooler
Version out of support	Unused, duplicate and invalid indexes
High-impact missing indexes	Estimated table bloat
Unused and duplicate indexes	Largest tables

Each rule has a documentation page with what it checks, why it matters, what to do and its limits.

Quick start

On Windows, open codeDB Lens from the Start menu. Pick the engine, enter the server and run the diagnosis. Connection profiles are saved; passwords go to the Windows Credential Manager.

Command line (Windows and Linux):

codedb-lens check --engine mssql --server prod01 --auth windows

codedb-lens check --engine pg --dsn-env PG_DSN

Passwords are never accepted as command-line arguments. Use integrated auth, an environment variable or a saved profile.

Use with AI (MCP)

Real Claude Code sessions against test databases; answers shortened.

Ask Claude, GitHub Copilot or Cursor about your database. codedb-lens mcp is a read-only MCP server that your AI client starts on your computer, with your saved profiles:

Diagnosis: with the Lens's minimal login, the AI runs the health check, reads recordings and explains what to fix, without reading business data.
Data: with a login that reads the tables you choose, the AI lists and describes them and answers questions with one SELECT at a time, within row and time limits.

codedb-lens mcp install --client claude-desktop --profile prod   # or vscode, cursor, claude-code

The app's AI (MCP) screen has the commands ready to copy. Guide: lens.codedb.com.br/mcp.

Minimum permissions

-- SQL Server

CREATE LOGIN codedb_lens WITH PASSWORD = ' '; GRANT VIEW SERVER STATE TO codedb_lens; GRANT VIEW ANY DEFINITION TO codedb_lens; GRANT CONNECT ANY DATABASE TO codedb_lens; -- per-database rules (indexes); no data access USE msdb; CREATE USER codedb_lens FOR LOGIN codedb_lens; ALTER ROLE db_datareader ADD MEMBER codedb_lens; ALTER ROLE SQLAgentReaderRole ADD MEMBER codedb_lens;

-- PostgreSQL (repeat GRANT CONNECT for each database)

CREATE ROLE codedb_lens LOGIN PASSWORD ' '; GRANT pg_monitor TO codedb_lens; GRANT CONNECT ON DATABASE app TO codedb_lens;

Supported versions

Engine	Supported	Best-effort
SQL Server	2017, 2019, 2022, 2025 (Windows and Linux), Azure SQL Managed Instance, Amazon RDS	2016 and older; Azure SQL Database (6 of 13 rules apply, see permissions)
PostgreSQL	15, 16, 17, 18, Amazon RDS, Aurora, Azure Flexible Server	14

Privacy

No telemetry. Lens makes two kinds of network calls: an optional, once-a-day version check against GitHub Releases that sends no data (--no-update-check or CODEDB_LENS_NO_UPDATE=1 turns it off), and, only when you ask for the free key, one registration request with the name and e-mail you type (or, when renewing, only the current key). See SECURITY.md.

Need continuous monitoring?

Lens shows a snapshot. codeDB watches your SQL Server and PostgreSQL instances around the clock, with history, baselines and alerts on Teams, Slack and e-mail.

Windows code signing

Windows binaries are built by GitHub Actions from this repository and are not code-signed yet (certificates are paid and this is a free project). Details, how to verify a download and warning-free alternatives: Why Windows shows a warning.

Contributing

New rules are especially welcome. A rule is a YAML file plus a SQL query, so you don't need to touch the Go code: see CONTRIBUTING.md, or just open an issue with a rule idea.
