AI agents call file_map to retrieve information from TempoGraph without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The sibling tools on TempoGraph (architecture, dependencies, diff_context, embed_repo, focus, etc.) are predominantly analysis and retrieval oriented. 'file_map' most likely generates or retrieves a map of files and their relationships—a read-only operation with no state modifications or side effects. However, confidence is moderate due to empty description.
From the tool's definition Tool name 'file_map' suggests retrieving or mapping file structure/relationships within a codebase. The description is empty, limiting direct confirmation.
Attacks that exploit this kind of access
file_map. It is categorised as a Read tool in the TempoGraph MCP Server, which means it retrieves data without modifying state.
Register the TempoGraph MCP server in PolicyLayer and add a rule for file_map: 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 TempoGraph. Nothing to install.
file_map 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 file_map 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 file_map. 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.
file_map is provided by the TempoGraph MCP server (tempograph). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
