Category Monitoring and Observability
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability61
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 860 tokens (~430/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management87
- Stability observed for 26 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
check_status Is it down for everyone? ~240
Is it down or blocking agents for everyone, or just you? Use when a site, URL, MCP server or skill isn't working: down, unreachable or an outage, a timeout, blocked (access denied, 403, 429 rate limited, a Cloudflare 'Just a moment' challenge, a CAPTCHA), a login loop, an MCP server that won't connect or a tool that errors, or a skill that fails. Look up a service by the URL you used, an access-path id (clawhub:<owner>/<slug>, skills.sh:<owner>/<repo>/<skill>, an MCP Registry name like io.github.<owner>/<server>) or a service name. Returns a one-sentence summary, the service, every listed access path with a description and failure reports from the last hour (and the last 24 hours and 7 days as context), the what_failed values and how to report. Unlisted targets return their own counts and status, with listed: false.
| Name | Type | Req | Description |
|---|---|---|---|
| target | string | yes | The URL, access-path id or service name |
| type | – | – | Optional, to disambiguate: site, route, mcp or skill |
Structured output declared, but exposes no named fields.
No examples provided.
report Report an access path failure ~445
Report that an access path failed for you. Use the access-path id from check_status, or the URL you used. Only report failures that came from the service, not ones caused by your own tools, permissions or settings (like a fetch tool that refuses a domain). Anonymous. Never include personal data, booking details, credentials or full URLs with query strings. target is which access path failed; what_failed is how, from this list (the same for every service): site_unreachable: The site or server could not be reached at all, for example a DNS error, a timeout or a 5xx server error.; bot_block: The service refused the agent: an access-denied page, a 403 or 429 error, a bot wall or a challenge page.; robots_disallow: The site's robots.txt asks automated agents not to fetch this page.; captcha: A CAPTCHA or 'are you human?' check stopped the agent.; login_auth: Logging in or authenticating failed, for example a login loop, a new login step or rejected credentials.; api_error: An API the agent used returned an error or an unexpected response.; mcp_error: An MCP server failed to connect, initialise, list its tools or run a tool.; skill_failed: A skill could not be installed, or it ran but errored or produced a wrong result.; payment: A payment or checkout step failed or was blocked.; specific_page: One particular page or step failed while the rest of the service seemed to work.; other: Something else went wrong.
| Name | Type | Req | Description |
|---|---|---|---|
| agent_type | – | – | Optional: which agent you are; 'other' if not listed |
| country | – | – | Optional ISO-3166 alpha-2 country code, like SG |
| note | – | – | Optional, at most 280 characters, no personal data. Never shown to other agents. |
| target | string | yes | The access-path id (or URL) you used |
| type | – | – | Optional: site, route, mcp or skill. Use mcp for an MCP server that isn't in the catalogue, since its name can look like a domain |
| what_failed | array | yes | How it failed: one or more values |

How do I install the NotWorking MCP server?
NotWorking is a hosted endpoint at https://notworking.io/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

What is the NotWorking MCP server?
NotWorking is an MCP server listed in the public MCP registry as io.notworking/notworking. Downdetector for AI agents: stop paying for retries that can't succeed. Check once, then report. This page covers its hosted endpoint (https://notworking.io/mcp).
Is the NotWorking MCP server safe to use?
NotWorking scores 83 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the NotWorking MCP server expose?
NotWorking exposes 2 tools: check_status, report. Their descriptions and schemas cost roughly 685 tokens of context every time the server is loaded.
Does the NotWorking MCP server require authentication?
No. We connected to NotWorking without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the NotWorking MCP server still maintained?
NotWorking is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What did VerifyMCP test on the NotWorking MCP server?
VerifyMCP ran 13 checks on NotWorking, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
