Lists every published ISM release (historical, current, and any future tags as soon as they appear upstream). Returns tag, version id, commit SHA, and release date parsed from the tag.
AI agents call list_versions 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 pure read operation that queries and returns information about ISM release versions. It has no side effects, does not execute code, does not modify data, and does not delete anything. The metadata returned (tags, version IDs, commit SHAs, release dates) is informational only.
From the tool's definition Tool 'lists every published ISM release' with 'returns tag, version id, commit SHA, and release date' — retrieves metadata about ISM versions without modifying any data.

Lists every published ISM release (historical, current, and any future tags as soon as they appear upstream). Returns tag, version id, commit SHA, and release date parsed from the tag. 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 list_versions: 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.
list_versions 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 list_versions 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 list_versions. 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.
list_versions 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.
list_versions is one line of ISM MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
