mysql-mcp copilot-instructions.md

mysql-mcp copilot-instructions.md is an instructions file for GitHub Copilot from neverinfamous/mysql-mcp. It costs 1,678 tokens per session, scanned A, original, MIT.

Code-review instructions for a MySQL MCP server, which lets an AI agent interact with MySQL databases. They cover architecture, caching, transports, validation, authentication, and integrations.

In plain words
What is it for?
They are for reviewing tool filtering, Code Mode, metadata caching, HTTP or standard-input transports, parameter aliases, bearer-token or OAuth security, and MySQL ecosystem integrations.
Why use it?
They give reviewers concrete rules for checking database access, request validation, security, performance, and supported connection methods.

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

mysql-mcp copilot-instructions.md 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 4d 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.

mysql-mcp — Copilot Code Review Context

Enforce Core Architecture Rules

Ensure PRs adhere to these SSoT architectural rules:

  • Tool filtering skips MySQL connections when using exclusively router, proxysql, or shell tools.
  • Code Mode (mysql_execute_code) significantly reduces token usage.
  • Cache: METADATA_CACHE_TTL_MS controls the cache TTL (default 30000).
  • Transports: Supports stdio and streamable http (MCP v2 stateless architecture via NodeStreamableHTTPServerTransport).
  • Validation: Ensure parameter alias validation at the MCP boundary (via the Dual-Schema Pattern).
  • Authentication: Secure connections with Bearer Tokens or OAuth.
  • Features: Tool filtering, token logging, and ecosystem integrations for MySQL Router, ProxySQL, and Shell.

Review Session Context

Read memory://briefing/mysql-mcp from memory-journal-mcp before starting. This provides essential real-time context:

  • Recent journal entries — what was just worked on by the development agent
  • GitHub status — open issues, PRs, CI status, milestones
  • Workflow runs — recent CI/CD results
  • Copilot review summaries — your own recent review findings

For detailed session handoff context, search for entries tagged session-summary. These contain end-of-session notes from the development agent.

Log review issues using mj_execute_code. Agents review these findings during their next session briefings.

Uphold Coding Standards

Standardize File Naming

  • Files and folders: Always kebab-case (schema-manager.ts, tool-filter.ts)
    • Exception: .github repository templates may use snake_case.
  • Never PascalCase or camelCase for filenames

Maintain Modularity

  • File size limit: Source files stay under ~500 lines
  • Split pattern: foo.ts → foo/ directory with sub-modules + foo/index.ts barrel re-export
  • Logical grouping: Split by functional cohesion, not arbitrary line counts

Enforce Type Safety

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.
