list_webhooks
AI agents call list_webhooks to retrieve information from GitHub MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Listing webhooks retrieves existing webhook metadata and configurations without modifying, executing, or deleting any data. This is a query operation with no side effects. The absence of a description limits confidence to 0.7, but the naming convention strongly indicates a read-only data retrieval function typical of GitHub API inspection tools.
From the tool's definition Tool name 'list_webhooks' indicates retrieval of webhook configurations. The 'list' prefix is a standard Read operation pattern. Tool description is empty, reducing confidence slightly.
Attacks that exploit this kind of access
list_webhooks. It is categorised as a Read tool in the GitHub MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GitHub MCP Server MCP server in PolicyLayer and add a rule for list_webhooks: 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 GitHub MCP Server. Nothing to install.
list_webhooks 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_webhooks 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_webhooks. 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_webhooks is provided by the GitHub MCP Server MCP server (software-engineer-mj/github-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
