Arc MCP Server Overview

Arc is a Model Context Protocol (MCP) server that bridges the gap between large language models and real‑world hosting environments. It empowers developers—especially those who may not be familiar with command‑line tooling—to deploy web applications through conversational prompts. By exposing a rich set of tools, resources, and guided prompts over MCP, Arc turns a typical deployment workflow into an interactive dialogue that can be driven by AI assistants such as Claude.

The core problem Arc solves is the friction inherent in deploying modern web frameworks to diverse hosting platforms. Developers often need to juggle provider‑specific commands, credential management, and platform quirks (e.g., SSH key handling for shared hosts). Arc abstracts these details behind a single, AI‑friendly interface. It supports popular serverless providers like Netlify and Vercel, as well as traditional shared hosting via SSH/SFTP and PHP/MySQL stacks. Credentials are stored securely in a configurable path, eliminating the need to expose secrets during conversations.

Key capabilities include:

• Framework‑specific deployment logic that understands the nuances of each stack (currently Wasp, with plans for Next.js and Astro).
• Multi‑provider operations that translate a single deployment intent into provider‑specific actions, whether it’s pushing to a Git repo for Netlify or uploading files over SFTP for shared hosts.
• Guided prompts that walk users through each step, asking clarifying questions and offering troubleshooting tips when errors arise.
• Secure credential handling, ensuring that provider tokens or SSH keys are never exposed in conversation logs.

In practice, a developer can ask an AI assistant to “deploy my Wasp app to Netlify,” and Arc will prompt for any missing information, fetch stored credentials, run the necessary build commands, and trigger a Netlify deployment—all while keeping the user in the loop. Similarly, deploying to a traditional shared host becomes as simple as confirming SSH credentials and letting Arc handle the file transfer.

Arc’s modular architecture makes it easy to extend. New frameworks or hosting providers can be added by implementing a handler that plugs into the existing MCP interface. This design not only streamlines current workflows but also positions Arc as a future‑proof solution for evolving deployment landscapes.
