Turn PostgreSQL, MySQL, MariaDB, SQL Server, Oracle, SQLite or Snowflake into MCP tools and a REST API, with API keys and per-table role-based access.

MCP-PostgreSQL-Ops is a professional MCP server for PostgreSQL database operations, monitoring, and management. Supports PostgreSQL 12-17 with comprehensive database analysis, performance monitoring, and intelligent maintenance recommendations through natural language queries.

Ask your database questions in natural language. mnemiq generates candidate SQL with an LLM, then runs deterministic checks on shape, access, dialect and query plan before a single row is read — and refuses when it can't answer safely. Exposes db_read and get_schema over MCP with per-tool grants. Postgres, Oracle, Snowflake, Databricks, DuckDB, SQLite. Apache-2.0.

Turn SQL templates + YAML into REST APIs and MCP tools — one static binary with embedded DuckDB (Parquet, Postgres, BigQuery, S3 and 50+ sources), per-tool RBAC, and DuckLake caching.

Expert-level PostgreSQL database analysis MCP server for AI assistants.

Free, open-source desktop database manager for 130 engines (PostgreSQL, SQL Server, Oracle, MySQL, MongoDB, Redis, Snowflake, BigQuery and more) that works as a local MCP server for Claude Code, Claude Desktop, Cursor, Codex, VS Code and Windsurf. Per-connection access levels (none, structure, read, write), prod connections capped at read-only, every write requires your approval, revocable per-client tokens and a local audit log.

Privacy-first local memory vault every AI shares over MCP. Markdown + SQLite on your machine; Claude, ChatGPT, Cursor, and any MCP client read and write it live. No cloud, no account, no telemetry.

A local memory engine any AI tool can use. You own the SQLite file. Install with `npx -y @factmem/mcp`.

Keeps Jira Cloud, Jira Server, Linear or its own built-in tracker (plus Confluence pages) in one local SQLite file on your machine. The MCP tools answer from that file: SQL, full-text search across issues, comments and wiki pages, issue detail, sprint and retro reads. Also ships as a Claude Desktop extension (.mcpb).

Local memory for AI agents. Beliefs keep their source, certainty and revision history in one SQLite file. MCP server, CLI and Agent Skill. Zero dependencies.

IMAP and SMTP for AI agents. Read, search, thread, send and organize mail through a local SQLite cache. MCP server, CLI and Agent Skill. Zero dependencies.

A local library of Agent Skills. Write, rank, search and roll back SKILL.md procedures in a git repo with a SQLite index. MCP server, CLI and Agent Skill.

Telegram bots for AI agents. Send, moderate and search a local SQLite mirror of your bot's chats. MCP server, CLI and Agent Skill. Zero dependencies.

Zero-config knowledge base for AI coding agents. Loads your markdown docs into a searchable database and exposes them as MCP tools — search, read, and manage documentation without leaving your editor. Works instantly with SQLite (no setup), upgrades to PostgreSQL + pgvector for hybrid semantic search. Includes skills for searching docs (/gnosis:search), health checks (/gnosis:status), doc management (/gnosis:manage), and first-time setup (/gnosis:setup). 6 MCP tools, 3 resources, FTS5 keyword search, 176 tests.

Federated search across personal humanMCP servers. Find listings, offers, trades by humans. SQLite + FTS5, 3 MCP tools: search_marketplace, list_servers, get_server.

Connect AI assistants to HyperLake to discover clusters, inspect catalogs and run SQL through a local MCP bridge; requires a HyperLake account.

Memory and Context framework that organises memories in a "memory palace" structure (rooms, loci, chunks), uses hybrid retrieval, manages memory decay, and runs entirely on the customer's hardware with no cloud dependency. Embeddings run locally through ONNX Runtime, storage is single-file SQLite, and integrations include a LangGraph checkpoint saver, a LangChain adapter, an MCP server and a REST API.

Access and manage MariaDB or MySQL databases using an MCP server.

Production-grade Model Context Protocol (MCP) server for unified SQL database access. Connect multiple databases through a single MCP server with schema discovery, relationship mapping, caching, and safety controls.

MeMesh 是跑在你自己電腦上的 AI Agent 協作層。記憶、指定收件人的訊息和改善提案，都放在同一個 SQLite 檔案裡。Claude Code、Codex、Cursor、Gemini，或你自己接的本機模型，都能透過 MCP、HTTP 或 CLI 使用；不綁單一廠商，也不用先把資料送上雲端。開源、MIT 授權、免費使用。

Zero-dependency persistent AI memory using SQLite. Dual-store, pluggable embeddings, 10 MCP tools.

ohmyho.st is an all-in-one Vercel, Supabase and Resend alternative that your coding agent operates. This MCP server lets Codex, Claude Code, Cursor, Hermes or OpenClaw deploy a GitHub app (Vite, TanStack Start, Next.js), give it a managed Postgres database, send and receive transactional email, connect custom domains, export encrypted SQL backups and track usage, credits and spending limits. One balance covers hosting, database and email. Dev and Prod are separate, and you keep your own auth provider. Local stdio server, Apache-2.0, mirrored from the npm package @amerged/ohmyhost-mcp. Install: npm install --global @amerged/ohmyhost-cli @amerged/ohmyhost-mcp. Docs: https://docs.ohmyho.st/agents/mcp
