Open a data file in jamovi. Supports .omv, .csv, .sav, .xlsx, .ods, .dta, .sas7bdat, .por, .txt formats.
AI agents call jamovi_open 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.
Opening a file loads data into the jamovi session for viewing/analysis. It reads from the filesystem and initializes the session state, but does not modify, delete, or create any data. The primary action is reading/loading a file, making this a Read category tool. Severity is low as misuse would only load an unintended dataset into the local session.

Attacks that exploit this kind of access
Open a data file in jamovi. Supports .omv, .csv, .sav, .xlsx, .ods, .dta, .sas7bdat, .por, .txt formats. 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_open: 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_open 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_open 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_open. 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_open 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.
