AI agents call list_users to retrieve information from Coverity Connect 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 user information without modifying, deleting, or executing operations. It is a straightforward query operation. Severity is medium rather than low because user enumeration can expose organizational structure and user identities, which may be sensitive in some contexts, but there are no destructive or operational effects.
From the tool's definition Tool name 'list_users' and description 'List all users in Coverity Connect' indicate data retrieval with no side effects. Lists enumerable user data from the system.

Documented attack patterns abuse exactly the kind of access list_users gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Coverity Connect MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_users:
{
"version": "1",
"default": "deny",
"tools": {
"list_users": {}
}
}list_users is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all users in Coverity Connect. It is categorised as a Read tool in the Coverity Connect MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Coverity Connect MCP Server MCP server in PolicyLayer and add a rule for list_users: 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 Coverity Connect MCP Server. Nothing to install.
list_users 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_users 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_users. 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_users is provided by the Coverity Connect MCP Server MCP server (keides2/coverity-connect-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Coverity Connect MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
