Lists existing Fossil tickets.
AI agents call task_list to retrieve information from Agent-VC MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves ticket data from Fossil SCM without creating, modifying, deleting, or executing any operations. It is a straightforward read operation with minimal security risk. Even if an AI agent misuses it by listing all tickets, the only consequence is information disclosure of existing tickets, which typically have limited sensitivity in most environments.
From the tool's definition Tool name 'task_list' and description 'Lists existing Fossil tickets' indicate a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
Lists existing Fossil tickets. It is categorised as a Read tool in the Agent-VC MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Agent-VC MCP Server MCP server in PolicyLayer and add a rule for task_list: 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 Agent-VC MCP Server. Nothing to install.
task_list 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 task_list 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 task_list. 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.
task_list is provided by the Agent-VC MCP Server MCP server (manbothq/agent-vc-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
