AI agents call get_object to retrieve information from Recall MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves an object from blockchain storage (Recall bucket) with no side effects. It is a read-only operation analogous to a GET request. No data is created, modified, or deleted. The low severity reflects minimal blast radius—an AI agent retrieving objects cannot cause irreversible harm or financial loss.
From the tool's definition Tool name 'get_object' and description 'Get an object from a Recall bucket' indicate retrieval of data without modification.
Documented attack patterns abuse exactly the kind of access get_object gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Recall MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_object:
{
"version": "1",
"default": "deny",
"tools": {
"get_object": {}
}
}get_object 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 an object from a Recall bucket. It is categorised as a Read tool in the Recall MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Recall MCP Server MCP server in PolicyLayer and add a rule for get_object: 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 Recall MCP Server. Nothing to install.
get_object 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_object 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_object. 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_object is provided by the Recall MCP Server MCP server (recallnet/recall-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Recall MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
