What stop_chronolog does on CLIO Adios
AI agents invoke stop_chronolog to trigger actions in CLIO Adios. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why stop_chronolog is rated High
The tool performs a disconnect operation against ChronoLog, an external service. While not destructive (data is not deleted) or financial, it actively terminates a session and releases resources, which is an execution action with external effects. The high severity reflects that improper disconnection could leave resources in an inconsistent state or interrupt critical scientific data workflows.
From the tool's definition 'Release the story handle and disconnect from ChronoLog' indicates termination of an active connection and resource cleanup. Releasing handles and disconnecting represent operational control actions that trigger external system state changes.
Attacks that exploit this kind of access
The rule that runs stop_chronolog safely
PolicyLayer is an MCP gateway: it sits between your AI agents and CLIO Adios, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For stop_chronolog, this is the rule to start with:
stop_chronolog stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect CLIO Adios, apply this rule, and every stop_chronolog call is checked against it from then on.
Questions about stop_chronolog
Release the story handle and disconnect from ChronoLog. It is categorised as a Execute tool in the CLIO Adios MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the CLIO Adios MCP server in PolicyLayer and add a rule for stop_chronolog: 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 CLIO Adios. Nothing to install.
stop_chronolog is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the stop_chronolog 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 stop_chronolog. 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.
stop_chronolog is provided by the CLIO Adios MCP server (pypi:clio-kit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
