AI agents call get_history to retrieve information from CSV Editor without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns operation history metadata. It performs a read-only retrieval operation with no capability to modify, delete, or execute any operations. The blast radius is minimal as it only exposes past operation records. Confidence is high given the clear read-only semantics and the presence of undo/redo and history management features in the server context.
From the tool's definition Tool is named 'get_history' with description 'Get operation history for a session' — retrieves historical data without modification or side effects.
Documented attack patterns abuse exactly the kind of access get_history gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and CSV Editor, and nothing reaches the server without passing your rules. This is the rule we recommend for get_history:
{
"version": "1",
"default": "deny",
"tools": {
"get_history": {}
}
}get_history is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get operation history for a session. It is categorised as a Read tool in the CSV Editor MCP Server, which means it retrieves data without modifying state.
Register the CSV Editor MCP server in PolicyLayer and add a rule for get_history: 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 CSV Editor. Nothing to install.
get_history 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 get_history 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 get_history. 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.
get_history is provided by the CSV Editor MCP server (santoshray02/csv-editor). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from CSV Editor, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
