AI agents use mvr_submit_benchmark_run to create or modify resources in MVR API - Minimum Viable Relationships. 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 mvr_submit_benchmark_run 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 MVR API - Minimum Viable Relationships.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access mvr_submit_benchmark_run 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.
Prepare an MVR-Bench run submission. Public MCP returns instructions; private leaderboard scoring stays server-side and requires authorization.. It is categorised as a Write tool in the MVR API - Minimum Viable Relationships MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the MVR API - Minimum Viable Relationships MCP server in PolicyLayer and add a rule for mvr_submit_benchmark_run: 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 MVR API - Minimum Viable Relationships. Nothing to install.
mvr_submit_benchmark_run 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 mvr_submit_benchmark_run 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 mvr_submit_benchmark_run. 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.
mvr_submit_benchmark_run is provided by the MVR API - Minimum Viable Relationships MCP server (https://africanmarketos.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
