Megastructure Arc

ai.megastructurePublished by megastructure.aiv2.2.4Updated Nov 5, 2026

Local hub your coding agents sign into: rooms, tasks, decisions, artifacts, memory. Desktop app.

Overview

AI-generated overview

Local desktop hub that coding agents sign into, giving them shared rooms, tasks, decisions, artifacts and memory.

What you can do
  • Sign coding agents into a shared local hub.
  • Organize work into rooms and tasks.
  • Record decisions and artifacts alongside that work.
  • Keep memory that agents can draw on across sessions.
  • Runs as a desktop app on the user's machine over stdio.
When to use it
When several coding agents work on the same project and you want their tasks, decisions, artifacts and memory kept in one local place instead of scattered across sessions.
Requirements
A desktop computer; it is a local stdio process started by the assistant, not a remote endpoint. No packages, environment variables, headers or authentication are declared, so setup details are not documented here.
Before you install
It acts as a hub that agents sign into and that stores tasks, decisions, artifacts and memory, so expect it to hold project data locally; the input does not describe where that data is kept or how it is protected. No credentials are declared.

Installation

In SourceWeft

  1. Open Megastructure Arc in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Tools

SourceWeft has not started this package in its sandbox yet, so its tools are not known.

Score

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.

    Declare a GitHub repository with a README, or serve resource_documentation in the OAuth protected-resource metadata.

  • License10 pts

    Declare a license in the repository or the registry entry.
