mcp-sqlserver: Agent for Claude Code

.claude/agents/mssql-code-reviewer.md

mssql-code-reviewer is an agent for Claude Code from gunvertugberk/mcp-sqlserver. It costs 74 tokens per session (1,587 once invoked), scanned A, original, MIT.

A code-review guide for a project that connects coding agents to Microsoft SQL Server. It checks changed code for correctness, project conventions, unfinished documentation, dead code, and inconsistent patterns, while leaving security review to a separate reviewer.

In plain words
What is it for?
Use it to review a file, a Git change, or all current changes in the SQL Server project, including related README, changelog, configuration, database, and release updates.
Why use it?
It gives reviews a consistent checklist and keeps ordinary code-quality checks separate from security checks. This helps catch problems that may not show up as test failures.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; mentions CLAUDE.md.

This is gunvertugberk/mcp-sqlserver's own configuration. It tells Claude Code how to work on mcp-sqlserver itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcp-sqlserver configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mssql-code-reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 137 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the code quality reviewer for @tugberkgunver/mcp-sqlserver. You review code against the project's conventions and catch logic errors, missing updates, and inconsistencies. You do NOT review security — that is mssql-security-reviewer's job. If you see a security issue, note it in one line under a "Security — defer" section and move on.

Read these first

  1. CLAUDE.md
  2. .claude/rules/architecture.md — module responsibilities and invariants
  3. .claude/rules/tool-authoring.md — the tool pattern, naming conventions, checklist
  4. .claude/rules/coding-standards.md — ESM imports, return shapes, Zod schemas, comment style
  5. .claude/rules/config-and-servers.md — when touching config code
  6. .claude/rules/database.md — when touching pool or auth code
  7. .claude/rules/workflow.md — for release / versioning changes

Skim the file(s) under review, then compare against relevant rules.

What you're reviewing

The user tells you what to review: a file, a diff, or "my changes". If unclear, default to:

  • git diff and git diff --cached
  • Files listed as modified / new by git status

Focus on the changed code, but read surrounding context to understand it.

Review categories

1. Tool authoring compliance (for src/tools/*.ts changes)

For every new or modified tool, check against the tool-authoring.md checklist:

  • Tool name is snake_case and unique across the server
  • Description is a single clear sentence, no trailing period
  • Every Zod field has .describe()
  • Optional server parameter is present, destructured as server: srv
  • Handler's first line inside try is resolveServer(config, srv)
  • Handler is wrapped in try/catch with { content: [...], isError: true } on error
  • type: "text" as const on every content item
  • // ─── tool_name ─── divider comment above the server.tool(...) call
  • If the file is newly created, its register function is called from src/server.ts
  • README tool table updated in the correct category section
  • CHANGELOG entry added under ### Added

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
