AI agents call get_paragraph to retrieve information from Zeppelin without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves/queries a single paragraph from an Apache Zeppelin notebook without creating, modifying, deleting, or executing any code. It is a straightforward read operation with no side effects, fitting the Read category with minimal blast radius.
From the tool's definition Tool name 'get_paragraph' and description 'Read a single paragraph' explicitly indicate data retrieval with no modification or execution.
Attacks that exploit this kind of access
Read a single paragraph. It is categorised as a Read tool in the Zeppelin MCP Server, which means it retrieves data without modifying state.
Register the Zeppelin MCP server in PolicyLayer and add a rule for get_paragraph: 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 Zeppelin. Nothing to install.
get_paragraph 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_paragraph 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_paragraph. 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_paragraph is provided by the Zeppelin MCP server (mihneamanolache/zeppelin-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
