Parchi Relay

Parchi Relay (How To Use It)

This skill documents how to run the Parchi relay daemon, connect the browser extension as an agent, and use the CLI to drive browser automation.

What You Get

• A local relay daemon (/v1/rpc + /v1/extension) that brokers calls.
• A browser extension agent that connects to the daemon over WebSocket and executes browser tools.
• A CLI (parchi-relay / npm run relay) that can:
  • list agents
  • pick the default agent
  • list tools / call tools
  • run an agent task and wait for completion

Quickstart (Local)

1. Build everything:

npm install
npm run build

2. Start the relay daemon (terminal A):

npm run relay:daemon -- --token=<YOUR_TOKEN> --host=127.0.0.1 --port=17373

3. Load the extension (Chrome):

• Open chrome://extensions
• Enable Developer mode
• Load unpacked: dist/
• Open the extension sidepanel
• Settings -> Relay:
  • Enable: On
  • URL: http://127.0.0.1:17373
  • Token: <YOUR_TOKEN>
  • Click Apply

4. Confirm the agent is connected (terminal B):

npm run relay -- agents --token=<YOUR_TOKEN>

CLI Usage (Real Commands)

The CLI talks to the daemon over HTTP JSON-RPC.

Set env vars (recommended):

export PARCHI_RELAY_TOKEN="<YOUR_TOKEN>"
export PARCHI_RELAY_HOST="127.0.0.1"
export PARCHI_RELAY_PORT="17373"

List agents:

npm run relay -- agents

Doctor (sanity-check daemon, auth, agent connection, tool forwarding):

npm run relay -- doctor

Get/set default agent:

npm run relay -- default-agent get
npm run relay -- default-agent set agent-123

List tools (on default agent or a specific agent):

npm run relay -- tools
npm run relay -- tools --agentId=agent-123

Call a tool:

npm run relay -- tool getTabs --args='{}'
npm run relay -- tool getContent --args='{\"mode\":\"text\"}'

Run a full agent task and wait for completion:

npm run relay -- run "On the active tab, extract the main headline." --tabs=active --timeoutMs=600000

RPC Surface (What The Relay Exposes)

Relay daemon (POST /v1/rpc, Authorization: Bearer <token>):

• relay.ping
• agents.list
• agents.default.get
• agents.default.set { agentId }
• tools.list { agentId? }
• tool.call { tool, args, agentId? }
• agent.run { prompt, selectedTabIds?, agentId? }
• run.wait { runId, timeoutMs? }
• run.events { runId }

Extension agent (WebSocket /v1/extension?token=...):

• Sends: agent.hello (registers the agent)
• Receives: JSON-RPC requests (forwarded by daemon)
• Sends: JSON-RPC responses
• Can publish: run.event / run.done notifications (for streamed run telemetry)

Troubleshooting

• agents returns []:

  • confirm daemon token matches extension token
  • confirm you loaded dist/ (not packages/extension/)
  • in the extension, Settings -> Relay should show connected status (and any error message)

• Tool calls fail due to policy:

  • check the extension Settings -> Tool Permissions and Allowed Domains

Notes For Production Use

• Keep the relay token private. Treat it like a local admin password.
• Bind to 127.0.0.1 unless you explicitly intend to expose it.
• If you expose it beyond localhost, add additional auth and transport security.

Electron Agent Mode

Parchi now supports a dedicated relay-native Electron agent:

# Terminal A
PARCHI_RELAY_TOKEN=<TOKEN> npm run relay:daemon

# Terminal B
PARCHI_RELAY_TOKEN=<TOKEN> npm run electron:agent

Managed helper (recommended):

npm run electron:secure -- start
npm run electron:secure -- status
npm run electron:secure -- stop

Then select the Electron agent with:

npm run relay -- agents
npm run relay -- default-agent set <electron-agent-id>

Useful methods:

• tool.call with electron.launch
• tool.call with electron.connect
• tool.call with electron.snapshot, electron.click, electron.type, electron.press
