Returns OSCAL metadata (title, version, last-modified, oscal-version) for a given ISM release. Use
AI agents call get_version_metadata to retrieve information from ISM MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward query tool that retrieves and surfaces informational metadata about ISM document versions. It has no capability to modify data, trigger external operations, delete records, or affect financial systems.
From the tool's definition Tool returns metadata (title, version, last-modified, oscal-version) for ISM releases. The verb 'Returns' and the nature of the data (metadata about versions) indicate read-only retrieval with no side effects.
Attacks that exploit this kind of access
Returns OSCAL metadata (title, version, last-modified, oscal-version) for a given ISM release. Use. It is categorised as a Read tool in the ISM MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ISM MCP Server MCP server in PolicyLayer and add a rule for get_version_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 ISM MCP Server. Nothing to install.
get_version_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_version_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_version_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_version_metadata is provided by the ISM MCP Server MCP server (rusticeagle/ism-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
