AI agents use signal_summaries-generate to create or modify resources in Saber. 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 signal_summaries-generate 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 Saber.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access signal_summaries-generate 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.
Generate an AI summary consolidating insights from all completed company signals for a domain. It is categorised as a Write tool in the Saber MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Saber MCP server in PolicyLayer and add a rule for signal_summaries-generate: 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 Saber. Nothing to install.
signal_summaries-generate 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 signal_summaries-generate 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 signal_summaries-generate. 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.
signal_summaries-generate is provided by the Saber MCP server (https://mcp.saber.app/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
