create_knowledge_record · Todos MCP: Risk & Policy

WHAT IT DOES

What create_knowledge_record does on Todos

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

WHY IT NEEDS A POLICY

Why create_knowledge_record needs a policy

This tool creates new records in a local database (SQLite), which is a reversible write operation. It does not execute arbitrary code, delete data irreversibly, or move money. The severity is medium because misuse could pollute the knowledge base with incorrect information, but the impact is confined to local project state and is reversible through updates or deletions.

From the tool's definition Tool description states 'Create a local project knowledge record' — the verb 'Create' and action of storing 'decisions, architecture notes, tradeoffs, or task-linked context' in 'local SQLite state' indicates data creation and modification.
