AI agents call get_spec 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 retrieves (reads) documentation/specification data from the knowledge base. The verb 'Retrieve' and the read-only nature of fetching a document from a searchable SQLite database confirm it as a Read operation. No data is created, modified, deleted, or executed.
From the tool's definition Tool name is 'get_spec' and description states 'Retrieve a specification document for a specific project' — indicates a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
Retrieve a specification document for a specific 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 get_spec: 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.
get_spec 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 get_spec 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 get_spec. 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.
get_spec 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.
