log_system_pattern · SDOF Knowledge Base MCP: Risk & Policy

WHAT IT DOES

What log_system_pattern does on SDOF Knowledge Base

AI agents use log_system_pattern 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_system_pattern needs a policy

This tool writes a new system or coding pattern to persistent storage. It is a create/write operation with no indication of irreversibility or financial impact. Misuse could pollute the knowledge base with incorrect patterns, but effects are reversible (sibling tool delete_system_pattern_by_id exists). Severity is low as the blast radius is limited to knowledge base integrity.

From the tool's definition 'Log a system or coding pattern' - creates/stores a new pattern entry in the knowledge base

Verdict

log_system_pattern Rate-limited

log_system_pattern 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_system_pattern

What does the log_system_pattern tool do? +

Log a system or coding pattern. 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_system_pattern? +

Register the SDOF Knowledge Base MCP server in PolicyLayer and add a rule for log_system_pattern: 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_system_pattern? +

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

Can I rate-limit log_system_pattern? +

Yes. Add a rate_limit block to the log_system_pattern 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_system_pattern completely? +

Set action: deny in the PolicyLayer policy for log_system_pattern. 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_system_pattern? +

log_system_pattern 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.
