List documents and files associated with a site. Returns metadata for files uploaded to a site: spec sheets, maintenance documents, BIM source files, 3D models, and knowledge graph data. Useful for answering questions like
AI agents call tacit_list_files to retrieve information from Tacit MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves file metadata with no side effects—it does not create, modify, delete, or execute anything. It is a read-only query operation that lists documents associated with a site. The low severity reflects minimal risk from misuse: listing files poses no direct security, financial, or operational threat to the building system.
From the tool's definition Tool 'tacit_list_files' lists and returns metadata for files associated with a site (spec sheets, maintenance documents, BIM source files, 3D models, knowledge graph data).

List documents and files associated with a site. Returns metadata for files uploaded to a site: spec sheets, maintenance documents, BIM source files, 3D models, and knowledge graph data. Useful for answering questions like. It is categorised as a Read tool in the Tacit MCP MCP Server, which means it retrieves data without modifying state.
Register the Tacit MCP server in PolicyLayer and add a rule for tacit_list_files: 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 Tacit MCP. Nothing to install.
tacit_list_files 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 tacit_list_files 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 tacit_list_files. 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.
tacit_list_files is provided by the Tacit MCP server (ucl-sbde/tacit-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
