Glossa

Glossa

Glossa lets ChatGPT work inside one local coding workspace that the user explicitly exposes.

ChatGPT
  -> OAuth protected MCP relay
  -> authenticated outbound worker connection
  -> one local Git worktree or explicit directory

Glossa is an execution bridge, not an agent. ChatGPT owns the model, conversation, planning, and approvals. The local worker owns file containment and command execution.

Why Glossa

Codex and ChatGPT Work share usage. Glossa connects the regular Chat surface to one local workspace without putting another model, planner, or agent in the middle.

Status

Glossa is a Windows-first open beta. The managed relay is live at https://mcp.glossa.sh/mcp. A valid Glossa login activates access automatically.

Install the open-beta CLI with Node 24:

npm install --global @ariobarin/glossa@beta

Then expose one workspace. Glossa opens Google sign-in automatically when needed:

Set-Location C:\path\to\a\project
glossa

glossa start . is the explicit form. You can run additional workers in other terminals to expose more workspaces from the same computer. Use glossa status to verify login, relay access, enrolled devices, and active workers.

Starting glossa authorizes connected clients to modify files inside that root and run commands with the full environment and permissions of the Windows account that launched it. Press Ctrl+C to disconnect.

ChatGPT

Glossa is not listed in the public plugin directory yet, so add it as a custom app in Developer Mode during the open beta. Follow the quickstart to connect the managed Glossa endpoint.

See the [open beta guide](docs/open-beta.md) for safe setup, verification, and troubleshooting.

Local development

Node 24 and Docker are required. Start local Postgres, create .env when missing, build, and migrate with:

npm run dev:setup
npm run dev

Stop local Postgres with npm run dev:down.

Glossa uses the managed relay by default. See [self-hosting](docs/self-hosting.md) if you prefer to operate your own relay, database, identity configuration, and CLI build.
