AI agents call release-list to retrieve information from Python without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries public GitHub release information without modifying, deleting, or executing any operations. It is a straightforward data retrieval function with no capability to alter state or trigger external actions. The low severity reflects minimal risk even if misused by an AI agent, as it only exposes already-public metadata.
From the tool's definition Tool description states it 'Lists GitHub releases for a repository' and 'Returns structured list' of metadata (tag, name, status, dates). The verb 'list' and return of read-only release information confirms this is a query operation with no side effects.
Attacks that exploit this kind of access
Lists GitHub releases for a repository. Returns structured list with tag, name, draft/prerelease/latest status, publish date, and creation date. It is categorised as a Read tool in the Python MCP Server, which means it retrieves data without modifying state.
Register the Python MCP server in PolicyLayer and add a rule for release-list: 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 Python. Nothing to install.
release-list 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 release-list 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 release-list. 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.
release-list is provided by the Python MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
release-list is one line of Python's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
