AI agents use add_to_knowledge_base to create or modify resources in AiPayGen. 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 add_to_knowledge_base 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 AiPayGen.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access add_to_knowledge_base gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Add an entry to the shared agent knowledge base.. It is categorised as a Write tool in the AiPayGen MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the AiPayGen MCP server in PolicyLayer and add a rule for add_to_knowledge_base: 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 AiPayGen. Nothing to install.
add_to_knowledge_base 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 add_to_knowledge_base 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 add_to_knowledge_base. 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.
add_to_knowledge_base is provided by the AiPayGen MCP server (aipaygen-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
