timescale/pg-aiguide: MCP Server + Claude Plugin That Teaches Agents Better PostgreSQL (1.6K Stars)

GitHub·medium signal

Timescale shipped a combined MCP server and Claude Code plugin that injects Postgres documentation, query patterns, and antipattern warnings directly into coding agent context. At 1,630 stars it fills a specific and common gap: agents generating syntactically valid but performance-pathological SQL. Topics include claude-code-plugin and ai-coding, indicating it is purpose-built for Claude Code's plugin system introduced in v2.1.77–78.
