Retrieve raw OCR / extraction capability output for a completed workflow — every extracted field with its source coordinates, MRZ raw lines, barcode contents, and confidence per field. Lower-level than retrieve_document_data.
AI agents call retrieve_extraction_data to retrieve information from Mcp Ap2 without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves previously extracted data from completed workflows without modifying, deleting, or executing actions. It is a Read operation. Severity is medium (not low) because the context involves sensitive extraction data from identity documents in a payment authorization system, which could be valuable if exposed, but the tool itself does not mutate state or trigger transactions.
From the tool's definition Tool description: "Retrieve raw OCR / extraction capability output for a completed workflow — every extracted field with its source coordinates, MRZ raw lines, barcode contents, and confidence per field." The verb 'Retrieve' and 'raw output' indicate data…
Risk signalsBulk/mass operation — affects multiple targets
Documented attack patterns abuse exactly the kind of access retrieve_extraction_data gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Ap2, and nothing reaches the server without passing your rules. This is the rule we recommend for retrieve_extraction_data:
{
"version": "1",
"default": "deny",
"tools": {
"retrieve_extraction_data": {}
}
}retrieve_extraction_data is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Retrieve raw OCR / extraction capability output for a completed workflow — every extracted field with its source coordinates, MRZ raw lines, barcode contents, and confidence per field. Lower-level than retrieve_document_data. It is categorised as a Read tool in the Mcp Ap2 MCP Server, which means it retrieves data without modifying state.
Register the Mcp Ap2 MCP server in PolicyLayer and add a rule for retrieve_extraction_data: 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 Mcp Ap2. Nothing to install.
retrieve_extraction_data 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 retrieve_extraction_data 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 retrieve_extraction_data. 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.
retrieve_extraction_data is provided by the Mcp Ap2 MCP server (@codespar/mcp-ap2). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mcp Ap2, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
