Switchboard

Switchboard lets people share selected local agent sessions (Codex, Claude Code, Hermes, OpenCode, OpenClaw) with permitted people in their workspace. Prompts, answers and transcripts never leave the machine that ran them: the hosted backend only routes opaque ciphertext between paired devices.

This repo is the connector: the Python CLI, resident service and MCP server. The desktop app lives in switchboard-desktop, the hosted backend and web app in switchboard-control.

How it works

flowchart LR
    U[Caller asks a question] --> H[Caller harness]
    H <-->|MCP over stdio| L[Local MCP server]
    L <-->|loopback| C[Caller connector]
    C -->|signed encrypted envelope| M[Switchboard backend<br/>directory, grants, opaque mailbox]
    M -->|ciphertext only| W[Owner connector<br/>mailbox worker]
    W -->|decrypt, recheck grant and policy| A[Harness adapter]
    A --> S[Owner session<br/>or caller-isolated fork]
    A -->|encrypted answer, reverse path| H

• The connector discovers local harness sessions, publishes the shared ones to the backend directory, and runs the mailbox worker that executes incoming requests after rechecking the grant and the owner's local policy.
• The MCP server (launched by each harness) and the bundled switchboard-ask skill let an agent resolve and call another agent: ask.research is your own local agent, ask.sim.research an agent shared with you.
• The desktop app drives the CLI and the backend API; it has no business logic of its own. See switchboard-desktop.

Getting started

Requires Python 3.12+ and uv.

uv sync
make check        # pre-commit hooks, tests and build: the CI gate

make lint, make format, make typecheck and make test run the pieces individually.

To run the connector from your checkout against a backend:

uv run switchboard install --switchboard-url <control backend URL>
uv run switchboard pair --device-name "dev machine"
uv run switchboard status

install registers your harnesses and a per-user service (LaunchAgent, systemd user unit or Scheduled Task); start, stop and uninstall manage it. End users install the published package instead: uv tool install switchboard-connector.

CI publishes the connector to PyPI on a v* tag.
