Part of the Agentos MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents use create_agent to create or modify resources in Agentos. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

Without a policy, an AI agent could call create_agent repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Agentos.

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the create_agent tool do? +

Create a new AI agent from a natural language description. The agent will be configured with appropriate policies and safety guardrails. Example usage: - "Create an agent that processes customer feedback from support emails daily" - "Build a data pipeline that backs up my Documents folder to Google Drive" - "Set up an agent to monitor our API health and alert on issues" Returns the agent specification with recommended safety policies.. It is categorised as a Write tool in the Agentos MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_agent? +

Add a rule in your Intercept YAML policy under the tools section for create_agent. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Agentos MCP server.

What risk level is create_agent? +

create_agent is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_agent? +

Yes. Add a rate_limit block to the create_agent rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block create_agent completely? +

Set action: deny in the Intercept policy for create_agent. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides create_agent? +

create_agent is provided by the Agentos MCP server (@microsoft/agentos-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
