Get sift metadata and inferred extraction schema for a specific sift.
AI agents call get_sift to retrieve information from Sifter without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata and schema information for a sift, which is a read-only operation with no side effects. It queries existing data structure information without creating, modifying, deleting, or executing external operations.
From the tool's definition Tool name 'get_sift' and description 'Get sift metadata and inferred extraction schema for a specific sift' indicate retrieval of metadata and schema information without modification or deletion.
Documented attack patterns abuse exactly the kind of access get_sift gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sifter, and nothing reaches the server without passing your rules. This is the rule we recommend for get_sift:
{
"version": "1",
"default": "deny",
"tools": {
"get_sift": {}
}
}get_sift is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get sift metadata and inferred extraction schema for a specific sift. It is categorised as a Read tool in the Sifter MCP Server, which means it retrieves data without modifying state.
Register the Sifter MCP server in PolicyLayer and add a rule for get_sift: 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 Sifter. Nothing to install.
get_sift 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_sift 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_sift. 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_sift is provided by the Sifter MCP server (sifter-ai/sifter). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
