Create a draft FoodBlock on behalf of an agent. Draft blocks have state.draft=true. The human operator can approve or reject with foodblock_approve_draft.

AI agents use foodblock_agent_draft to create or modify resources in Foodblock. 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 foodblock_agent_draft repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Foodblock.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Create a draft FoodBlock on behalf of an agent. Draft blocks have state.draft=true. The human operator can approve or reject with foodblock_approve_draft.. It is categorised as a Write tool in the Foodblock MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Foodblock MCP server in PolicyLayer and add a rule for foodblock_agent_draft: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Foodblock. Nothing to install.
foodblock_agent_draft is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the foodblock_agent_draft rule in your PolicyLayer 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.
Set action: deny in the PolicyLayer policy for foodblock_agent_draft. 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.
foodblock_agent_draft is provided by the Foodblock MCP server (foodblock-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
