Perform mid-session quality checkpoint with workflow analysis and optimization recommendations.
AI agents call checkpoint to retrieve information from Session Buddy without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to analyze the current session state and provide recommendations — a read/analysis operation with no indication of modifying, deleting, or executing anything. However, 'checkpoint' could imply saving state (a Write action), and the description is vague about side effects, slightly lowering confidence.

Attacks that exploit this kind of access
Perform mid-session quality checkpoint with workflow analysis and optimization recommendations. It is categorised as a Read tool in the Session Buddy MCP Server, which means it retrieves data without modifying state.
Register the Session Buddy MCP server in PolicyLayer and add a rule for checkpoint: 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 Session Buddy. Nothing to install.
checkpoint is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the checkpoint 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 checkpoint. 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.
checkpoint is provided by the Session Buddy MCP server (lesleslie/session-buddy). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
