log_decision · SDOF Knowledge Base MCP: Risk & Policy

WHAT IT DOES

What log_decision does on SDOF Knowledge Base

AI agents use log_decision to create or update resources in SDOF Knowledge Base — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your SDOF Knowledge Base environment.

WHY IT NEEDS A POLICY

Why log_decision needs a policy

This tool creates a new decision record in the knowledge base. It writes/creates data persistently but is reversible (the sibling tool 'delete_decision_by_id' exists to remove it). Misuse could pollute the decision log with incorrect architectural records, leading to misguided future decisions, hence medium severity.

Verdict

log_decision Rate-limited

log_decision stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches SDOF Knowledge Base, so you can run agents against it safely.

FAQ

Questions about log_decision

What does the log_decision tool do? +

Log an architectural or implementation decision. It is categorised as a Write tool in the SDOF Knowledge Base MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on log_decision? +

Register the SDOF Knowledge Base MCP server in PolicyLayer and add a rule for log_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 SDOF Knowledge Base. Nothing to install.

What risk level is log_decision? +

log_decision is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit log_decision? +

Yes. Add a rate_limit block to the log_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.

How do I block log_decision completely? +

Set action: deny in the PolicyLayer policy for log_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.

What MCP server provides log_decision? +

log_decision is provided by the SDOF Knowledge Base MCP server (tgf-between-your-legs/sdof-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
