Is your MCP server actually deployable? Twelve questions across four domains — tool definitions & schemas, transport & auth, security hygiene, and operations. Deterministic scoring, a graded result, a remediation map pointing each gap at the deep-dive tool that closes it, and a §4 OpenChainGraph artifact with execution_hash.
Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.
Run the AINumbers MCP tool `run_mcp_deployability_diagnostic`. Task: 12-question scored diagnostic: graded A–F across tool definitions & schemas, transport & auth, security hygiene, and operations.
Call it with arguments: {"policy_parameters":{"q1":"yes","q2":"yes","q3":"yes","q4":"yes","q5":"yes","q6":"yes","q7":"yes","q8":"yes","q9":"yes","q10":"yes","q11":"yes","q12":"yes"}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
