macos_tcc_database
AI agents call macos_tcc_database to retrieve information from Velociraptor MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The TCC database is a system database in macOS that logs which applications have requested and been granted access to sensitive resources (camera, microphone, location, etc.). Accessing this database would be a Read operation for forensic investigation purposes, consistent with Velociraptor's incident response mission.

macos_tcc_database. It is categorised as a Read tool in the Velociraptor MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Velociraptor MCP Server MCP server in PolicyLayer and add a rule for macos_tcc_database: 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 Velociraptor MCP Server. Nothing to install.
macos_tcc_database 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 macos_tcc_database 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 macos_tcc_database. 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.
macos_tcc_database is provided by the Velociraptor MCP Server MCP server (snoe-findley/mcp-velociraptor). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
