MCP

An integration protocol connecting AI applications, tools and context sources.

OpnForm is an open-source form builder available as both a managed cloud service and a self-hosted application. Its repository documents practical operational details: bundle-size limits, PostgreSQL index migrations that keep writes available, isolated Docker environments for worktrees, and dependency security checks. It also provides an MCP server that lets AI agents create and preview drafts, with versioned previews that support restoring earlier revisions.

prompts.chat brings together community prompts for ChatGPT, Claude, Gemini, and other assistants, alongside an interactive book on prompt engineering. The repository also provides a CLI, a Claude Code plugin, and an MCP server for using prompts across different tools.

For a team, self-hosting provides a private prompt library with custom branding and authentication configured by the setup wizard. The integration examples range from npx prompts.chat to a remote MCP connection, without requiring a single access method.

Data API builder generates REST and GraphQL endpoints, as well as MCP tools, from Azure databases and on-premises stores. It supports several backends, including Azure SQL, SQL Server, PostgreSQL, MySQL and Cosmos DB, and runs in a container or locally during development.

Configuration defines entities and their permissions; DAB then translates requests into SQL. This layer reduces the API code teams need to maintain, while access remains shaped by the configuration and each database’s capabilities.

Engram: persistent memory for MCP-compatible AI agents

engram.gentlemanprogramming.comPermalink

Engram provides persistent memory for AI agents, compatible with any agent supporting the MCP protocol (Claude Code, Gemini CLI, Codex, VS Code, etc.). The tool runs as a single Go binary with no external dependencies, storing memories in a SQLite file with built-in FTS5 search. It features a TUI, Git sync, and a self-hostable cloud extension, while remaining local-first and open source under the MIT license.
