MCP Tools

AgentComms provides MCP (Model Context Protocol) tools that AI assistants can use for communication.

Voice Tools

These tools enable phone calls via Twilio.

Inbound Tools

These tools allow AI to check for messages sent by humans via the daemon.

Requires Daemon

These tools require the agentcomms daemon to be running. Start it with agentcomms daemon.

check_messages

Check for new messages sent to this agent from humans via chat.

Input:

{
  "agent_id": "claude",
  "limit": 10
}

Output:

{
  "messages": [
    {
      "id": "evt_01ABC123",
      "channel_id": "discord:123456789",
      "provider": "discord",
      "text": "Hey, can you also add unit tests?",
      "timestamp": "2024-01-15T10:30:00Z",
      "type": "human_message"
    }
  ],
  "agent_id": "claude",
  "has_more": false,
  "last_seen_id": "evt_01ABC123"
}

When to use:

• Periodically during long-running tasks
• After completing a subtask
• When waiting for build/test results

Parameters:

Parameter	Type	Default	Description
agent_id	string	env var or "default"	Agent to check messages for
limit	int	10	Maximum messages to return

get_agent_events

Get all recent events for an agent (messages, interrupts, status changes).

Input:

{
  "agent_id": "claude",
  "since_id": "evt_01ABC123",
  "limit": 20
}

Output:

{
  "events": [
    {
      "id": "evt_01ABC456",
      "agent_id": "claude",
      "channel_id": "discord:123456789",
      "type": "human_message",
      "role": "human",
      "timestamp": "2024-01-15T10:35:00Z",

      "payload": {"text": "Thanks!"}
    }
  ],
  "agent_id": "claude"
}

Parameters:

Parameter	Type	Default	Description
agent_id	string	env var or "default"	Agent to get events for
since_id	string	(none)	Only return events after this ID
limit	int	20	Maximum events to return

daemon_status

Check if the agentcomms daemon is running.

Input:

{}

Output (running):

{
  "running": true,
  "started_at": "2024-01-15T09:00:00Z",
  "agents": 1,
  "providers": ["discord", "telegram"]
}

Output (not running):

{
  "running": false
}

Agent ID Resolution

The inbound tools need to know which agent to query. Resolution order:

1. agent_id parameter in the tool call
2. AGENTCOMMS_AGENT_ID environment variable
3. Default: "default"

Set the environment variable in your MCP server configuration:

{
  "mcpServers": {
    "agentcomms": {
      "command": "/path/to/agentcomms",
      "env": {
        "AGENTCOMMS_AGENT_ID": "claude"
      }
    }
  }
}

Usage Patterns

Polling During Long Tasks

1. Start long-running operation
2. Every few minutes, call check_messages
3. If messages found, process them
4. Continue operation

Responding to Messages

1. Call check_messages
2. Read message from human
3. Process the request
4. Call send_message to respond

Checking Before Major Decisions

1. Before making a significant change
2. Call check_messages to see if human sent updates
3. Incorporate any new information
4. Proceed with decision
