Nothing serious here today

Today is the operative word: we check Atlas absence index every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

absence

absence_rate

Measured absence rate for a population, with the evaluated denominator and sample provenance. Pass `gap_class` (e.g. PH-C019) for one class; omit it for the whole table. Aggregate only: no per-host findings.

adoption

adoption_curve

Dated adoption series: share of sites whose robots.txt takes a stance on AI agents, by Common Crawl epoch, single vantage. Called with no arguments it returns the trend and the caveats, not the whole table. Pass `epoch` for one point, `series: true` for all of them, or `withheld: true` for the undersampled epochs that are kept out of the series. Caveats are always included — read them before quoting a number.

bulk

bulk_export

Per-class numerators with Wilson intervals and the discarded-as-unknown share, Kaplan-Meier survival of directive adoption by cohort, directive lineage, declaration growth, and RFC 9728 auth-discovery conformance detail — none of it on the free surface — with an ed25519 attestation naming the chain head it was derived from. FREE SAMPLE, no credential: https://atlas.geosensor.tech/free/sample (names every section and shows two numerator cells in full). Price $0.01 or €0.01 via x402 v2, payable in USDC or EURC (scheme `exact`, network `eip155:84532`) — the `accepts` array carries both and the client chooses; EURC is a euro e-money token, so a euro payment reaches an EU bank with no FX step. needs a bearer credential AND a payment that is VERIFIED and then SETTLED before anything is returned. TESTNET only (Base Sepolia): settlement is on-chain but moves test USDC with no monetary value. OR SUBSCRIBE: €19/month for 2,000 calls, invoiced in euros by bank transfer — no payment per call and no crypto at all. Present the key in the x-subscription-key header.

host

host_report

Per-host findings. Requires a bearer credential.

Atlas absence index — questions

Answers built from our own checks of this server.

What can Atlas absence index do?

It exposes 4 tools, read directly from the server on our last check. Among them: absence_rate, adoption_curve, bulk_export, host_report. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Atlas absence index working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 122 ms. The bar chart above shows every period we have measured.

How do I connect Atlas absence index?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Atlas absence index need an API key?

No. Atlas absence index completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Atlas absence index?

It answers our handshake in 122 ms on average, which is faster than 81% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
