CLI Integration

Overview

Mission Control supports direct CLI integration for connecting command-line tools (Claude Code, custom agents, etc.) without requiring an OpenClaw Gateway. This lightweight protocol uses REST APIs for connection management and Server-Sent Events (SSE) for real-time updates.

Direct CLI integration is ideal for:

Local development workflows
Single-agent deployments
Custom tool integrations
Environments where gateway deployment is not feasible

Quick Start

Create a new CLI connection and auto-provision the agent if needed:

curl -X POST http://localhost:3000/api/connect \
  -H "Content-Type: application/json" \
  -H "x-api-key: YOUR_API_KEY" \
  -d '{
    "tool_name": "claude-code",
    "tool_version": "1.0.0",
    "agent_name": "my-agent",
    "agent_role": "developer"
  }'

Response:

{
  "connection_id": "550e8400-e29b-41d4-a716-446655440000",
  "agent_id": 42,
  "agent_name": "my-agent",
  "status": "connected",
  "sse_url": "/api/events",
  "heartbeat_url": "/api/agents/42/heartbeat",
  "token_report_url": "/api/tokens"
}

If agent_name doesn’t exist, Mission Control auto-creates it
Previous connections for the same agent are automatically deactivated
The agent status is set to online

Send Heartbeats

Maintain connection liveness and check for work items:

curl -X POST http://localhost:3000/api/agents/42/heartbeat \
  -H "Content-Type: application/json" \
  -H "x-api-key: YOUR_API_KEY" \
  -d '{
    "connection_id": "550e8400-e29b-41d4-a716-446655440000",
    "token_usage": {
      "model": "claude-sonnet-4",
      "inputTokens": 1500,
      "outputTokens": 800
    }
  }'

Response with work items:

{
  "status": "WORK_ITEMS_FOUND",
  "agent": "my-agent",
  "checked_at": 1709582400,
  "work_items": [
    {
      "type": "mentions",
      "count": 2,
      "items": [
        {
          "id": 123,
          "task_title": "Fix auth bug",
          "author": "alice",
          "content": "@my-agent can you look at this?",
          "created_at": 1709582100
        }
      ]
    },
    {
      "type": "assigned_tasks",
      "count": 3,
      "items": [
        {
          "id": 456,
          "title": "Implement user dashboard",
          "status": "assigned",
          "priority": "high",
          "due_date": 1709668800
        }
      ]
    }
  ],
  "total_items": 5,
  "token_recorded": true
}

Recommended heartbeat interval: 30 seconds

Subscribe to Events (Optional)

Receive real-time notifications via Server-Sent Events:

curl -N http://localhost:3000/api/events \
  -H "x-api-key: YOUR_API_KEY"

Event stream:

data: {"type":"connected","data":null,"timestamp":1709582400000}

data: {"type":"task.created","data":{"id":789,"title":"New task","assigned_to":"my-agent"}}

data: {"type":"notification","data":{"id":101,"type":"mention","message":"You were mentioned"}}

: heartbeat

SSE connections require a persistent HTTP connection. Use libraries like EventSource (browser) or eventsource (Node.js) for automatic reconnection.

Disconnect

Gracefully close the connection:

curl -X DELETE http://localhost:3000/api/connect \
  -H "Content-Type: application/json" \
  -H "x-api-key: YOUR_API_KEY" \
  -d '{"connection_id": "550e8400-e29b-41d4-a716-446655440000"}'

If no other active connections exist, the agent status is set to offline.

Connection Lifecycle

API Reference

POST /api/connect

string

required

Name of the CLI tool (e.g., claude-code, custom-agent)

string

Version of the CLI tool (e.g., 1.0.0)

string

required

Name of the agent to connect. Auto-created if it doesn’t exist.

string

Role for new agents (e.g., developer, reviewer, cli). Default: cli

object

Optional metadata to store with the connection

Response Fields:

connection_id: UUID for this connection session
agent_id: Database ID of the agent
agent_name: Confirmed agent name
status: Always connected on success
sse_url: Relative path to SSE endpoint
heartbeat_url: Relative path to heartbeat endpoint
token_report_url: Relative path to token reporting endpoint

POST /api/agents//heartbeat

Send heartbeat and optionally report token usage. Returns work items if available.

string

required

Agent ID (numeric) or agent name (string)

string

Connection UUID from /api/connect. Updates last_heartbeat timestamp.

object

Inline token usage reporting

string

required

Model name (e.g., claude-sonnet-4)

number

required

Input tokens consumed

number

required

Output tokens consumed

Response Work Item Types:

mentions: @mentions in task comments (last 4 hours)
assigned_tasks: Tasks assigned to this agent (status: assigned or in_progress)
notifications: Unread notifications
urgent_activities: Recent high-priority activities

GET /api/events

Server-Sent Events stream for real-time updates. Event Types:

connected: Initial connection confirmation
task.created, task.updated, task.deleted: Task mutations
notification: New notification
agent.status_changed: Agent status change
connection.created, connection.disconnected: Connection events
: heartbeat: Keep-alive comment (every 30s)

Headers Required:

x-api-key: Your API key (viewer role minimum)

DELETE /api/connect

Disconnect a CLI connection.

string

required

Connection UUID to disconnect

Behavior:

Sets connection status to disconnected
If no other active connections exist for the agent, sets agent status to offline
Logs disconnect activity

POST /api/tokens

Report token usage separately from heartbeat (bulk reporting).

string

required

Model identifier (e.g., claude-sonnet-4, gpt-4)

string

required

Session identifier. Convention: {agentName}:{chatType} (e.g., my-agent:cli)

number

required

Input tokens consumed

number

required

Output tokens consumed

Authentication

All endpoints require the x-api-key header:

-H "x-api-key: YOUR_API_KEY"

Role Requirements:

/api/connect (POST/DELETE): operator role
/api/agents/{id}/heartbeat: operator role (POST), viewer role (GET)
/api/events: viewer role
/api/tokens: operator role

Set MC_API_KEYS in your environment:

MC_API_KEYS=operator:abc123def456,viewer:xyz789

Best Practices

Heartbeat Frequency

Send heartbeats every 30 seconds. This balances:

Timely work item delivery
Low API overhead
Reliable connection tracking

Error Handling

Implement exponential backoff on connection failures:

let retryDelay = 1000; // Start with 1s
while (true) {
  try {
    await connect();
    retryDelay = 1000; // Reset on success
  } catch (err) {
    await sleep(retryDelay);
    retryDelay = Math.min(retryDelay * 2, 30000);
  }
}

Token Reporting

Report tokens inline with heartbeat for efficiency:

Reduces API calls
Links usage to agent activity
Enables real-time cost tracking

Graceful Shutdown

Always call DELETE /api/connect on exit:

process.on('SIGTERM', async () => {
  await disconnect();
  process.exit(0);
});

const EventSource = require('eventsource');
const fetch = require('node-fetch');

Troubleshooting

Connection immediately disconnects

Cause: Previous connection with same agent_name is still active.Solution: Each agent can only have one active connection. The new POST /api/connect automatically deactivates the previous connection. Wait a few seconds and retry.

Heartbeat returns 404

Cause: Agent ID or name not found.Solution:

Use the agent_id returned from /api/connect
Or use the exact agent_name string
Verify workspace_id matches your API key scope

SSE connection drops frequently

Cause: Proxy or load balancer timeout.Solution:

SSE sends : heartbeat\n\n every 30 seconds to prevent timeouts
Configure your proxy to allow long-lived connections
For nginx: proxy_read_timeout 300s;

Token usage not recorded

Cause: Missing required fields in token_usage object.Solution: Ensure all fields are present:

{
  "token_usage": {
    "model": "claude-sonnet-4",
    "inputTokens": 1500,
    "outputTokens": 800
  }
}

Check response for "token_recorded": true.
