Otto configuration

Configure Otto Agents to access MCP servers and define their capabilities within your Ascend Project.

Organization

The otto.yaml configuration must be located within a dedicated otto directory in your Ascend Project:

Basic Agent setup

Configure Otto Agents in your otto.yaml file:

otto/otto.yaml

otto:
  agents:
    "Otto Chat":
      mcp_servers:
        - slack

Agent access control

Grant Agents access to specific MCP servers configured in mcp.yaml (see MCP guide):

otto/otto.yaml

otto:
  agents:
    "Otto Chat":
      mcp_servers:
        - slack

    "Pipeline Monitor":
      mcp_servers:
        - slack

Access patterns:

• Specific Agents: Only listed Agents can access the MCP servers
• Granular control: Different Agents can have different server access levels
• Multiple servers: In theory, Agents can access multiple MCP servers simultaneously

note

Currently, Ascend natively supports the Slack messaging integration via @modelcontextprotocol/server-slack.

See the MCP guide for more information.

Next steps

After configuring Otto Agents:

• Set up MCP servers following the MCP Setup Guide
• Configure specific integrations like Slack
• Test Agent functionality by triggering Otto actions
