weaken_confidence · Chronos MCP: Risk & Policy

WHAT IT DOES

What weaken_confidence does on Chronos MCP

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

WHY IT NEEDS A POLICY

Why weaken_confidence needs a policy

Based on the sibling tool 'boost_confidence' and the server's purpose of managing a knowledge graph, 'weaken_confidence' likely modifies the confidence score of a memory or knowledge graph node downward. This is a reversible write operation (confidence values can be boosted back). Empty description lowers confidence in this assessment.

From the tool's definition Tool name 'weaken_confidence' on a server that also has 'boost_confidence' — these are paired operations on memory/knowledge graph confidence scores. Description is empty.

Verdict

weaken_confidence Rate-limited

weaken_confidence 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.
