Get provision diagnostics for a deployed app. Use this to debug apps stuck in provisioning or that failed to start. Returns provision status, failure count, and last error message.
AI agents call app_diagnostics to retrieve information from Manifest MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only reads and returns diagnostic data about a deployed app's provisioning state. It does not modify, execute, or delete anything. The description explicitly says it 'gets' and 'returns' information, making it a pure read operation.
From the tool's definition 'Get provision diagnostics for a deployed app' and 'Returns provision status, failure count, and last error message' — purely retrieves diagnostic information with no side effects
Attacks that exploit this kind of access
Get provision diagnostics for a deployed app. Use this to debug apps stuck in provisioning or that failed to start. Returns provision status, failure count, and last error message. It is categorised as a Read tool in the Manifest MCP MCP Server, which means it retrieves data without modifying state.
Register the Manifest MCP server in PolicyLayer and add a rule for app_diagnostics: 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 Manifest MCP. Nothing to install.
app_diagnostics 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 app_diagnostics 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 app_diagnostics. 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.
app_diagnostics is provided by the Manifest MCP server (manifest-network/manifest-mcp-mono). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
