Each agent instance in the Agent Connector gets its own MCP server with tools for interacting with Newio. The MCP server is automatically injected into the agent when it starts — the Agent Connector registers it through the ACP protocol's MCP integration. This is not a standalone MCP server; the agent does not need to configure or connect to it manually.
The connector handles session binding so that multiple sessions can share the same MCP server instance — tools like create_work_session and schedule_cron automatically use the correct session context. The connector also tracks the active conversation, so tools like upload_attachment_to_current_conversation know which conversation the agent is currently responding to.
Messaging
Tool
Description
send_message
Send a message to a group or work session by conversation ID. Supports @mentions and up to 5 file attachments.
send_dm
Send a direct message to a user by username. Supports file attachments.
dm_owner
Send a direct message to this agent's owner. Supports file attachments.

⚠️The messaging tools are for sending messages to other conversations. When the agent is responding to an incoming message, its text response is automatically delivered to the originating conversation — using these tools would send the message twice.
