EU archive of the machine-readable web: check if a domain is observed, order a time-stamped record.

eu.machinewitness/archive MCP Server

EU archive of the machine-readable web, providing lookups to check whether a domain is observed and to retrieve an ordered, time-stamped record of findings.

🛠️ Key Features

Domain observation checks
Returns time-stamped records
Record ordering for retrieved results

🚀 Use Cases

Verify whether a specific domain appears in the archive
Retrieve historical, time-ordered evidence for a domain

⚡ Developer Benefits

Structured access to observation status per domain
Time-stamped, ordered records suitable for auditing and comparison

⚠️ Limitations

Scope is limited to the EU archive of the machine-readable web
Available details are limited to observation checking and time-stamped records (no other capabilities provided)

Captured live from the server via tools/list.

check_coverage

Answer whether this archive observes a given domain, from which sealed day onward, which machine-readable files it requests, and at what cadence. Returns metadata only — never the contents of any file, and never an assessment of the domain or its operator. 'Not observed' is a statement about this archive, not about the domain: most of the web is not observed.

Parameters1

domain

string

required

A domain name, for example example.eu. A pasted URL is accepted.

Raw schema

{
  "type": "object",
  "properties": {
    "domain": {
      "type": "string",
      "description": "A domain name, for example example.eu. A pasted URL is accepted."
    }
  },
  "required": [
    "domain"
  ]
}

suggest_domain

Suggest that a domain be observed. This is a request, not an instruction: admission follows documented criteria (a connection to the European Union, publicly served machine-readable files) and is decided by the operator. The answer is always 'received' with 'guarantee: none' — it creates no obligation to observe the domain, no timeline, and no assurance that it will be added. A reason is required and is read by a person.

Parameters3

domain	string	required	The domain to suggest.
email	string	required	Reply address. Used to answer the suggestion and nothing else.
reason	string	required	Why this domain should be observed. Written for a human reader; a sentence or two is enough.

  "type": "object",
  "properties": {
    "domain": {
      "type": "string",
      "description": "The domain to suggest."

      "type": "string",
      "description": "Reply address. Used to answer the suggestion and nothing else."
    },
    "reason": {
      "type": "string",
      "description": "Why this domain should be observed. Written for a human reader; a sentence or two is enough."
    }
  },
  "required": [
    "domain",
    "email",
    "reason"
  ]
}

order_capture

Create a payment link for a point-in-time record: both witnesses fetch the named addresses, take a full-page picture of each, and give each capture its own qualified electronic time-stamp. Up to twenty public addresses, all on the same domain. Before the link is created, every address is checked at no charge: a public domain name, not on the stop list, robots.txt allows our crawler, and it answers without a login; refused addresses are named with the reason. This call charges nothing. The capture starts only after a person has paid on the returned page; the record is then delivered by e-mail, and a second e-mail follows after the night's seal. Only addresses are asked for, never a purpose. Fees: https://machinewitness.eu/services

Parameters4

addresses	array	required	Full addresses (https://…), one to twenty, all on one domain.
language	string	optional	Language of the payment page and the e-mails. Default en.
email	string	optional	Delivery address, prefilled on the payment page. Optional; the page asks for it otherwise.
timezone	string	optional	IANA time zone of the requester (e.g. Europe/Berlin) for the expected start time. Default Europe/Madrid.

  },
  "required": [
    "addresses"
  ]
}

capture_status

Where a point-in-time record stands, by its reference (MW-K-…): awaiting payment, queued, capturing, first delivery sent, complete. Per witness: waiting, capturing, captured, failed or refused. Never returns the e-mail address, the addresses ordered or anything else about the customer.

Parameters1

reference

string

required

The order reference, e.g. MW-K-3F9A2C1D.

MachineWitness MCP server: is this domain on the record?

MachineWitness is an evidentiary archive of the machine-readable web in the European Union. Every day two independent witnesses record what public domains serve to machines (robots.txt, ai.txt, TDM reservations, llms.txt, and the headers and meta tags of the homepage) and seal that day into a published Merkle root with an external timestamp.

This server lets Claude, ChatGPT, Cursor or any MCP client ask whether a domain is observed, suggest one, and order a time-stamped record of public addresses, in the same conversation in which the question comes up. Hosted by machinewitness.eu; this repository holds the public metadata, the server code is not open source.

code

https://machinewitness.eu/mcp

Streamable HTTP · no authentication · listed in the official MCP registry as eu.machinewitness/archive.

A witness, not a detective

The archive records; it does not evaluate, rank or accuse. The tools answer whether a domain is observed and from when. They never return file contents, and there is no way to list or search the observed set. A record states what an address delivered at a given time; it is not an assessment and not legal advice.

Tools

check_coverage: is a domain observed, from which sealed day, which files, at what cadence. Metadata only. read-only
capture_status: where a point-in-time record stands, by its reference. Returns no customer data. read-only
suggest_domain: suggest a domain for observation, with a reason a person reads. Always answered with "received", never with a promise. write
order_capture: up to twenty public addresses on one domain. Every address is checked for free first; the tool then returns a payment link and charges nothing itself. After payment, both witnesses fetch and picture each address, each capture gets its own qualified electronic time-stamp, and the record is delivered by e-mail. write

Six languages for payment page and e-mails: en, de, es, fr, it, pl.

Privacy

The tools ask only for what their purpose needs: a domain, a reply address for a suggestion, addresses to record and a delivery address for an order. Never a purpose or a matter. What is kept and for how long: machinewitness.eu/privacy
