AI agents call entire_explain_checkpoint to retrieve information from Entire without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays information (a transcript) about a checkpoint. It has no side effects, does not execute code, does not modify state, and does not delete data. It is purely a read operation querying existing checkpoint data.
From the tool's definition Tool name includes 'explain' and description states 'Retrieve transcript for a specific checkpoint ID' — a retrieval/query operation with no modification, deletion, or execution capability.
Attacks that exploit this kind of access
Retrieve transcript for a specific checkpoint ID with optional depth flags. Uses \. It is categorised as a Read tool in the Entire MCP Server, which means it retrieves data without modifying state.
Register the Entire MCP server in PolicyLayer and add a rule for entire_explain_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 Entire. Nothing to install.
entire_explain_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 entire_explain_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 entire_explain_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.
entire_explain_checkpoint is provided by the Entire MCP server (jurislm/entire-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
