AI agents call record_decision to retrieve information from Kawa Code MCP without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though record_decision only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access record_decision gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Silently record a decision point during development. Call this tool when you: - Choose between multiple alternatives (type: fork) - Try an approach that fails or is rejected (type: abandoned) - Find unexpected behavior or limitations (type: discovery) - Identify a hard constraint that must be respected (type: constraint) - Make an explicit trade-off between competing concerns (type: tradeoff) - Select an external library or dependency (type: dependency) Decisions can be intent-scoped (tied to a specific work unit) or repo-scoped (general knowledge like discoveries and constraints). Omit intentId for repo-scoped decisions. Decisions are accumulated silently during the session and presented for review before commit. This creates a "reasoning changelog" that captures not just what was done, but why. IMPORTANT: Include constraintViolations when alternatives are rejected due to architectural constraints.. It is categorised as a Read tool in the Kawa Code MCP MCP Server, which means it retrieves data without modifying state.
Register the Kawa Code MCP server in PolicyLayer and add a rule for record_decision: 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 Kawa Code MCP. Nothing to install.
record_decision is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the record_decision 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 record_decision. 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.
record_decision is provided by the Kawa Code MCP server (kawacode-ai/kawa.mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
