Get a release asset from a GitHub repository
AI agents call get_release_asset to retrieve information from Mcp Github without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves existing release asset data and has no side effects. It does not modify, delete, or execute operations. The blast radius of misuse is minimal: an unauthorized user might download a release asset they shouldn't have access to, but the integrity of the repository and its data remain unaffected.
From the tool's definition get_release_asset retrieves or fetches a release asset—a downloadable file associated with a GitHub release. The verb 'get' and the action of retrieving data (not modifying, deleting, or executing) align with Read operations.
Attacks that exploit this kind of access
Get a release asset from a GitHub repository. It is categorised as a Read tool in the Mcp Github MCP Server, which means it retrieves data without modifying state.
Register the Mcp Github MCP server in PolicyLayer and add a rule for get_release_asset: 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 Mcp Github. Nothing to install.
get_release_asset 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_release_asset 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_release_asset. 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_release_asset is provided by the Mcp Github MCP server (@missionsquad/mcp-github). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
