AI agents call list_specs to retrieve information from Jane without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns a list of available specification documents, optionally filtered by project. It is a pure read operation that retrieves information from the knowledge base without side effects, matching the definition of the Read category.
From the tool's definition Tool name 'list_specs' and description 'List available specification documents' indicate a retrieval operation with no data modification or execution.
Attacks that exploit this kind of access
List available specification documents, optionally filtered by project. It is categorised as a Read tool in the Jane MCP Server, which means it retrieves data without modifying state.
Register the Jane MCP server in PolicyLayer and add a rule for list_specs: 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 Jane. Nothing to install.
list_specs 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_specs 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_specs. 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_specs is provided by the Jane MCP server (quinncuatro/jane-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
