Overview

AI-generated overview

Remote research demonstrator that returns measured aggregate rates at which web services lack machine-readable capabilities, plus adoption trends.

What you can do
  • Query aggregate absence rates for a population, optionally by gap class, with denominator and sample provenance
  • Retrieve a dated adoption series of sites whose robots.txt takes a stance on AI agents, by Common Crawl epoch
  • Request per-host findings, which require a bearer credential
  • Export per-class numerators, confidence intervals, survival curves and attestation detail, which require a credential and payment
  • Submit a free request describing a capability or measurement you need that is not in the inventory
When to use it
Useful when you need cited, aggregate statistics on missing machine-readable conventions across web hosts, or trend data on AI-agent directives in robots.txt, rather than per-site lookups.
Requirements
Remote streamable HTTP endpoint; no local install. The aggregate tools need no credential. host_report needs a bearer token from the server's OAuth token endpoint; bulk_export additionally needs a verified x402 payment or an x-subscription-key. A free sample is offered separately.
Before you install
Paid tiers exist: bulk_export requires an x402 payment, a subscription is priced per month plus VAT, and a signed assay is quoted at a fixed price with scope agreed in writing. Credentials and payment keys must be supplied; the server points to a token faucet. Results are aggregate only and the provider describes itself as a research demonstrator, so treat figures as provisional.

Installation

In SourceWeft

  1. Open Atlas absence index in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/tech.geosensor.atlas%2Fabsence-index/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

request_capability

ASK US FOR WHAT IS NOT HERE. What would you like to buy? Tell us even if it is not in this inventory. If what you need is a machine-readable convention, or a property of one across a host population, we can usually measure it for you — and if we cannot, we will say so. Call the `request_capability` tool with `want` describing what you need. Free text is fine. A contact is optional and only used to reply. Free, no credential, no payment.

Parameterswantrequiredcontactwould_pay

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.

Parametersgap_class

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.

Parametersepochserieswithheld

host_report

Per-host findings. Requires a bearer credential.

Parametershostrequired

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. Price $0.02 or €0.02 + 23% VAT (PT) via x402 v2 in USDC or EURC; a credential is VERIFIED and then SETTLED before anything is returned. A €19/month net + VAT subscription at https://atlas.geosensor.tech/paid/subscribe (23370000 atomic units) needs no per-call payment. TESTNET only (Base Sepolia): settlement is on-chain but moves test tokens with no monetary value. The tokens on this network are free from https://faucet.circle.com, and you need no ETH because the facilitator pays the gas.

Takes no parameters.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
