Turn Any API into an AI‑Ready MCP Service with Just a Few Lines of Code

FastAPI MCP Converter

FastAPI MCP is an open‑source tool that lets developers turn any existing FastAPI endpoint into an MCP service that AI models can call directly. By inserting a few lines of code into a FastAPI app, the tool automatically exposes the full API documentation and data structures via the MCP protocol, enabling AI platforms such as Cursor to invoke the service without additional configuration.

ACI.dev – One‑Click MCP Orchestrator

ACI.dev is an open‑source platform designed for AI agents to simplify the integration of external tools. Instead of configuring multiple MCP services (e.g., Hacker News, Tavily, Gmail), users set up a single ACI MCP service that decides which underlying APIs to call to fulfill a given task.

The platform ships with more than 600 standardized connectors for common applications such as Google Calendar and Slack, so developers do not need to write authorization or API‑calling code from scratch.

Dive – Cross‑Platform MCP Desktop Client

Dive is a cross‑platform desktop application that acts as a hub connecting large language models (e.g., ChatGPT, Claude) with local or network tools via the MCP protocol. It enables AI to perform actions such as downloading videos with youtube‑dlp, accessing maps, crawling the web, or reading and editing files.

The client runs on Windows, macOS, and Linux, offers a multilingual UI and automatic updates, allowing non‑programmers to build functional AI assistants without writing code.
