What capture_knowledge_snapshot does on Todos
AI agents use capture_knowledge_snapshot 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 capture_knowledge_snapshot is rated Medium
The tool creates/writes a new snapshot artifact containing project knowledge (decisions, plans, conventions). This is a reversible write operation — it stores data but does not delete or overwrite existing records irreversibly. Misuse could pollute the knowledge base with incorrect information, hence medium severity.
From the tool's definition Capture a project knowledge snapshot bundling decisions, plans, and conventions.
Attacks that exploit this kind of access
The rule that runs capture_knowledge_snapshot safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Todos, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For capture_knowledge_snapshot, this is the rule to start with:
capture_knowledge_snapshot 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Todos, apply this rule, and every capture_knowledge_snapshot call is checked against it from then on.

Register the Todos MCP server in PolicyLayer and add a rule for capture_knowledge_snapshot: 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 Todos. Nothing to install.
capture_knowledge_snapshot is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the capture_knowledge_snapshot 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 capture_knowledge_snapshot. 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.
