Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

economic-activities-register-mtr scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Economic Activities Register (MTR)

Access

  • Operator search form: GET https://mtr.ttja.ee/juriidiline_isik?m=96
  • Form submission: POST https://mtr.ttja.ee/juriidiline_isik/filter/action
  • Response: server-rendered HTML using a session cookie and CSRF token; no login is required for public searches.

Retrieve

  1. Create one cookie-preserving HTTP session and fetch the search form.
  2. Extract juriidiline_isik_filters[_csrf_token].
  3. Submit the form in the same session. Useful fields are:
    • juriidiline_isik_filters[nimi][text]
    • juriidiline_isik_filters[registrikood][text]
    • juriidiline_isik_filters[tegevusala_id]
    • juriidiline_isik_filters[tegevusala_tyyp]: 1 for notices or 2 for licences
    • juriidiline_isik_filters[valjund_valjad][]: request nimi, registrikood, and any other output columns needed
  4. Follow the redirect to /juriidiline_isik and parse rows from div.sf_admin_list.
  5. Follow each row's /juriidiline_isik/<id> link. The detail page contains Majandustegevusteated and Tegevusload tables with validity and activity fields.

Preserve the operator name, registration code, MTR record number, activity, validity dates, current/archive state, and detail URL.

Limits

  • Since 25 June 2025, notices and licences are being moved from MTR to https://tarvik.ttja.ee/; MTR alone is no longer guaranteed to be exhaustive for current activity.
  • The public form is stateful. A POST without the cookie and current CSRF token will not reproduce the search.
  • Use the dedicated notice (/majandustegevusteade) or licence (/tegevusluba) forms when the user asks for record-first rather than operator-first results; they use the same session/CSRF pattern.

Verify

Require the submitted filter value to reappear under Kasutatud filtrid, at least one result row containing both name and registration code, and a working /juriidiline_isik/<id> detail link.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
