Local hub your coding agents sign into: rooms, tasks, decisions, artifacts, memory. Desktop app.
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.
Installation
In SourceWeft
- Open Megastructure Arc in the dashboard and add it to a workspace.
- 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.

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.
- DescriptionRequired15 pts

- Documentation15 pts
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.
