AI agents call notion_get_block to retrieve information from Sage MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves a specific block from Notion by its ID. Getting/fetching data is a Read operation. There are no side effects, no data modification, no code execution, and no destructive actions. The severity is low because it merely returns existing data without risk of unintended consequences, limited only by authentication and access controls to that block.
From the tool's definition Tool name 'notion_get_block' and description 'Get a specific block by ID' indicate a retrieval operation with no modification or execution capability.
Documented attack patterns abuse exactly the kind of access notion_get_block gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sage MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for notion_get_block:
{
"version": "1",
"default": "deny",
"tools": {
"notion_get_block": {}
}
}notion_get_block is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get a specific block by ID. It is categorised as a Read tool in the Sage MCP MCP Server, which means it retrieves data without modifying state.
Register the Sage MCP server in PolicyLayer and add a rule for notion_get_block: 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 Sage MCP. Nothing to install.
notion_get_block 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 notion_get_block 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 notion_get_block. 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.
notion_get_block is provided by the Sage MCP server (sagemcp/sagemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
