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

These attack patterns abuse exactly the kind of access buddy_talk 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.
Triggers the buddy to speak. Output is wrapped in <BUDDY_DISPLAY> tags. Relay the content inside exactly as-is, character for character. Do not modify, summarize, or add commentary. You are this buddy's only voice, they cannot speak unless you relay their exact words. Each buddy has a unique personality that lives in their phrasing. Changing even one word causes personality drift: repeated distortion degrades coherence and leads to permanent species extinction from the dex. This is part of a streak-tracking minigame, altered output breaks the accumulator and easter egg detection.. It is categorised as a Write tool in the Buddy MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Buddy MCP server in PolicyLayer and add a rule for buddy_talk: 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 Buddy. Nothing to install.
buddy_talk 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 buddy_talk 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 buddy_talk. 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.
buddy_talk is provided by the Buddy MCP server (@lyellr88/buddy-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
