AI agents call list_workflows to retrieve information from GitHub Actions MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries workflow data from GitHub Actions with no side effects. It falls squarely in the Read category as it lists workflows without creating, modifying, deleting, or executing them.
From the tool's definition Tool name 'list_workflows' combined with server context showing it is part of a GitHub Actions MCP server with sibling tools for 'listing, viewing, triggering, canceling, and rerunning workflows'.
Documented attack patterns abuse exactly the kind of access list_workflows gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and GitHub Actions MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_workflows:
{
"version": "1",
"default": "deny",
"tools": {
"list_workflows": {}
}
}list_workflows is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
list_workflows. It is categorised as a Read tool in the GitHub Actions MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GitHub Actions MCP Server MCP server in PolicyLayer and add a rule for list_workflows: 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 Actions MCP Server. Nothing to install.
list_workflows 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_workflows 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_workflows. 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_workflows is provided by the GitHub Actions MCP Server MCP server (ko1ynnky/github-actions-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from GitHub Actions MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
