Get the running TDC API build version and process start time. Useful for confirming MCP ↔ API connectivity and gating on server version.
AI agents call get_api_version to retrieve information from TDC MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about the API server (version and start time) without modifying, executing arbitrary operations, or triggering external side effects. It is a diagnostic/status check operation, which falls under the Read category. The low severity reflects minimal blast radius if an AI agent calls it—it cannot corrupt data, execute code, or cause harm.
From the tool's definition Tool description states it 'Get[s] the running TDC API build version and process start time' with purpose 'confirming MCP ↔ API connectivity and gating on server version'. This is purely informational retrieval with no side effects.
Attacks that exploit this kind of access
Get the running TDC API build version and process start time. Useful for confirming MCP ↔ API connectivity and gating on server version. It is categorised as a Read tool in the TDC MCP Server MCP Server, which means it retrieves data without modifying state.
Register the TDC MCP Server MCP server in PolicyLayer and add a rule for get_api_version: 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 TDC MCP Server. Nothing to install.
get_api_version 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_api_version 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_api_version. 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_api_version is provided by the TDC MCP Server MCP server (truedungeoncompanion/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
