Get metadata for all submissions of a form.
AI agents call get_submission_metadata to retrieve information from Nettskjema 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 metadata about form submissions without creating, modifying, deleting, or executing any operations. It is a straightforward read operation that queries existing data. The blast radius is minimal—worst case, an agent could discover metadata about submissions but cannot alter forms, delete data, or trigger external actions. Low severity reflects the read-only, non-destructive nature.
From the tool's definition Tool name 'get_submission_metadata' and description 'Get metadata for all submissions of a form' indicate a retrieval operation with no modification or deletion of data.
Attacks that exploit this kind of access
Get metadata for all submissions of a form. It is categorised as a Read tool in the Nettskjema MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Nettskjema MCP Server MCP server in PolicyLayer and add a rule for get_submission_metadata: 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 Nettskjema MCP Server. Nothing to install.
get_submission_metadata 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_submission_metadata 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_submission_metadata. 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_submission_metadata is provided by the Nettskjema MCP Server MCP server (orjahren/nettskjema-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
