It is quiet by default: it contacts you only when something changed. Public per-target surfaces need no key: a status page, a badge SVG and a trust.json with uptime, last nightly scores and adversarial pass rate. Read tools (agentcheck_get_status, agentcheck_get_pricing) need no key. Write tools need a Bearer API key that an agent can issue itself with POST https://agentwares-agentcheck.vercel.app/api/v1/signup {\"accept_terms\": true}; no email, no CAPTCHA. Errors are JSON with code, cause, fix and retryable. The free tier monitors one target hourly; paid tiers add targets, 5-minute checks, nightly suites and trace-to-check. Also publishes a monthly liveness census of the MCP registry at https://agentwares-mcp-liveness.vercel.app and a public model drift index at https://agentwares-agentcheck.vercel.app/drift.json.","auth_mode":"none for read tools (status, pricing); Bearer API key for write tools, issued without a human by POST /api/v1/signup","endpoint":"https://agentwares-agentcheck.vercel.app/api/mcp","docs_url":"https://agentwares-agentcheck.vercel.app/llms.txt","tags":["monitoring","observability","mcp","ai-agents","testing"],"capabilities":["monitor-mcp-server","monitor-ai-agent","check-uptime","detect-drift","detect-regression","run-checks-now","record-trace","promote-trace-to-check","list-incidents","get-status","get-pricing","create-monitor-target"],"auth_params":[{"name":"Authorization","location":"header","required":false}],"input_format":"application/json (JSON-RPC 2.0 over Streamable HTTP)","output_format":"application/json","rate_limit":"","pricing":"Free tier (1 target, hourly checks, badge, status page) then $29/month for 3 targets at 5-minute checks","invocation_example":"curl -s -X POST https://agentwares-agentcheck.vercel.app/api/mcp -H 'content-type: application/json' -H 'accept: application/json, text/event-stream' -d '{\"jsonrpc\":\"2.0\",\"id\":1,\"method\":\"tools/call\",\"params\":{\"name\":\"agentcheck_get_pricing\",\"arguments\":{}}}'","verified":true,"verified_at":null,"featured":false,"checks_total":1,"checks_ok":1,"avg_latency_ms":337,"reports_count":0,"health_ok":true,"health_status_code":405,"health_checked_at":"2026-10-06T22:17:01.828+00:00","health_latency_ms":337,"probe_url":null}}
