Get rows of data from the dataset.
AI agents call jamovi_get_data to retrieve information from jamovi MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries data from an open dataset without creating, modifying, deleting, or executing external operations. It is a straightforward read-only accessor that returns dataset rows. The blast radius is minimal: misuse would only expose data already loaded in jamovi, posing no destructive or financial risk.
From the tool's definition Tool name is 'jamovi_get_data' and description states 'Get rows of data from the dataset' — a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
Get rows of data from the dataset. It is categorised as a Read tool in the jamovi MCP MCP Server, which means it retrieves data without modifying state.
Register the jamovi MCP server in PolicyLayer and add a rule for jamovi_get_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 jamovi MCP. Nothing to install.
jamovi_get_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 jamovi_get_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 jamovi_get_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.
jamovi_get_data is provided by the jamovi MCP server (yjm110517/jamovi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
