List streams, optionally filtered by project
AI agents call list_streams 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 or queries stream data from the Coverity Connect platform, filtered optionally by project. It has no side effects—it does not create, modify, delete, or execute any operations. It belongs in the Read category with low severity since exposing a list of streams carries minimal security risk compared to tools that could alter project configurations or delete findings.
From the tool's definition Tool name 'list_streams' and description 'List streams, optionally filtered by project' indicate a query/retrieval operation with no modification or deletion of data. The verb 'list' is a read-only action.
Documented attack patterns abuse exactly the kind of access list_streams 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_streams:
{
"version": "1",
"default": "deny",
"tools": {
"list_streams": {}
}
}list_streams is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List streams, optionally filtered by project. 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_streams: 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_streams 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_streams 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_streams. 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_streams 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.
