🎨 Open-source design MCP server + shadcn/ui registry — AI design systems for Claude Code, Cursor, Codex, GitHub Copilot & any MCP client. 31 brand-grade themes (Linear, Stripe, Vercel, Notion, Apple, Supabase, Figma…) + design tokens, UI principles & WCAG rules. Install any component with one command.

Token conscious database MCP server for Postgres, MySQL, SQL Server, Oracle, MariaDB, SQLite.

Enables small local models and other agents to read and query spreadsheet files locally, run SQL and cleaning, audit formulas, make Excel-correct edits, and generate branded dashboards with token-budgeted responses across selectable tool tiers.

Enables Claude Code and Codex to write, update, and retrieve durable long-term memories that survive session boundaries and context compaction. All recall runs locally against a single SQLite file using hybrid BM25, embedding, and recency ranking cut to an explicit token budget, with no cloud dependency.

Enables Claude and other MCP clients to safely query PostgreSQL data and perform limited order-status updates through scoped bearer tokens, read-only transactions, row caps, and an audit log.

Enables Claude to list Iceberg tables and run read-only DuckDB SQL queries, including time travel by snapshot, with per-caller token authentication and audit logging.

Enables AI assistants to look up credentials such as API keys, database URLs, and service tokens by account name, and to read inbox messages like notifications, alerts, and task assignments routed to the agent, all from self-hosted infrastructure.
