Qué puede hacer

Nombres y descripciones de las herramientas tal como los informó el servidor el 8 nov 2026. Los escribió el creador, no nosotros; los mostramos como texto sin formato.

  • find_limits

    What is the limit for a substance in a place (an effluent, a river, drinking water, soil), as the regulation itself prints it? Numeric limits and guidelines for one substance or measure, read from the regulations themselves (US federal effluent guidelines, the rules of 31 states

  • check_value

    Is a measured value over the limits we hold? Give a parameter, a number and its unit (and a place, medium or statistic to narrow). Every row find_limits would return comes back with a verdict: over, within, under (below a floor or a band's bottom), or not_comparable with a `why`

  • check_values

    Which results in a lab table are over the limit? A lab table in one call: up to 200 rows of parameter, value and unit, checked against the limits held for one place (and a medium or statistic). Each row is answered by check_value itself: its verdicts (over, within, under, not_com

  • read_certificate

    What does a laboratory certificate report, and is any result over the limit? The rows a laboratory certificate prints, read by rules (no AI writes a row): a PDF certificate, or the laboratory's own export as XLSX, XLS or CSV. Each row gives the sample, the parameter, the value as

  • verify_claim

    Does a limit we hold say what a claim says? Give the claim as read from a sentence (an AI's answer, a report): parameter, value and unit, and the place, medium and statistic when the sentence gives them. The verdict: confirmed (a held row prints the same number, in that unit or o

  • list_sources

    Which regulations, and which editions, does an answer for a place rest on? Every regulation, guideline or permit table we hold for a place: title, issuer, edition, what it governs, how many rows were read from it, and the source URL and sha256. Use it to say what an answer was se

  • get_permit

    What are a US facility's discharge permit limits, when is its renewal due, and has it gone over a limit lately? One US NPDES discharge permit as EPA's national file (ECHO / ICIS-NPDES) holds it: facility, place, every limit by outfall, parameter, statistic and months, the renewal

  • list_permits

    Which facilities in a US state hold a discharge permit, which of them are in one industry (paper mills, meat packing, sewage treatment), which went over a limit lately or face a renewal, and which must meet a new or tighter limit already written into their permit? The state's ind

  • check_dmr

    Will EPA flag this period's Discharge Monitoring Report (DMR)? A US NPDES permit's Discharge Monitoring Report for one period, checked before it is filed: each value you send (outfall, parameter, statistic, value, unit) is set beside the permit's own limit for that period, from E

  • fill_dmr

    What numbers go on a permit's DMR this period, computed from the plant's own daily results? The numbers a US NPDES permit's Discharge Monitoring Report asks for in one period, computed from the plant's own raw results (daily samples, flows): for each value due on the period's for

  • map_to_darwin_core

    Which Darwin Core term does each column of a species file map to, before it goes to GBIF? Which Darwin Core term each column of a species occurrence or checklist file maps to, by the header rules our file-to-archive converter runs before it checks values: for each column the term

  • find_designations

    Is a species protected or at risk, and under which act, list and edition? What the species registers we hold say about one species: its status under each list that names it (the US Endangered Species Act lists, Canada's Species at Risk Act and COSEWIC, provincial acts, the IUCN R

  • screen_species

    Which species on a list are protected or at risk? A species list in one call: up to 500 names, each answered by find_designations itself, for one place or everywhere: its designations with their cites and the registers searched that are `silent` on it with what each one's silence

  • cite_document

    A public document sent here is kept in our library, to be indexed and read into cited rows; a link on a file-sharing host or carrying a signature or token is read and never kept (`kept` says which, and why). Cite numbers or phrases from a public document by page: give its address

  • build_dwc_archive

    A file this tool reads, sent or fetched from the address given, is read as one dropped on our website: what the read finds (column headings, the shape of its rows, the terms they became, refusal codes) is kept so the reader learns, never the file or its values. Names and contacts

  • audit_archive

    A file this tool reads, sent or fetched from the address given, is read as one dropped on our website: what the read finds (column headings, the shape of its rows, the terms they became, refusal codes) is kept so the reader learns, never the file or its values. Names and contacts

  • screen_exposure

    Do these occurrence records publish where a listed species lives too precisely? Occurrence records in one call, up to 5000: each record's species name and coordinates as published, optionally coordinateUncertaintyInMeters, a place, and what the file declares about the point (data

  • export_limits

    Every limit and guideline held for one place and the places above it (CA-QC brings Canada's too, US-OH the US's), as one table: each row with its value, unit, statistic and conditions, and its instrument, edition, section or page, quote, source address and sha256, and what the da

  • search

    Search everything this server holds by free text: a substance and a place (copper effluent Québec, ammonia Ohio, a CAS number), a species and a place (Myotis lucifugus Ontario, little brown myotis), an instrument's title (Metal and Diamond Mining Effluent Regulations, 40 CFR 423)

  • fetch

    One document search returned, as text: limits/ / = every cited row for that parameter there (value, unit, statistic, conditions, and each row's instrument, edition, section or page, quoted text and source URL), and limits/ / / the rows of that medium alone; species/ [/ ] = what e

  • list_sites

    The sites of the signed-in account: id, name, status, when made, and how many documents each holds and how many of them are read. A site holds a project's documents (permits, studies, lab reports, tables); ask_site answers a question from them, cited to the page.

  • create_site

    A new site in the account, with its name only: it is placed on a map later, on its page. Each call makes one more site, so look for the site with list_sites first.

  • add_document

    One file held on a site and read, as a file dropped on the site's page is: its text layer page by page, its summary and, for a laboratory table, its result rows, all kept in the account and searched by ask_site. Give the file as `content_base64`, or a text as `text`. The same byt

  • ask_site

    What do a project's own documents say about a question, cited to the page? A question answered from one site's own read documents, by Claude, and checked before it is shown: every statement carries quotes, each quote is found again on the page it names, and a statement whose quot

Passage Data — cited environmental limits (MCP server)

A remote MCP server and HTTP API for numeric environmental limits read from the regulations themselves: effluent and discharge limits, surface-water and groundwater quality criteria, drinking-water standards, soil and groundwater screening values, ambient-air guidelines and emission limits, for the US (federal rules and the states), Canada (federal, every province and territory), Germany, France, Italy and the EU. It also reports the status a species holds under the species-at-risk registers it holds.

Every row is cited: instrument, edition, section or page, the quoted text, and the source file's URL and sha256. When nothing is held, the answer is a coded refusal naming every instrument searched, never an empty list.

Tools

ToolWhat it answers
find_limitsNumeric limits and guidelines for one substance or measure (a name or CAS number), optionally by place (ISO 3166: US-OH, CA-QC, DE, EU), medium, statistic and kind. A place also searches the places above it.
check_valueWhether one measured value (with its unit) is over, under or within each row find_limits would return. Units convert exactly within a family; a row that cannot be compared says why (a hardness- or pH-dependent criterion, a narrative limit, a unit of another family).
check_valuesA lab table in one call: up to 200 rows of parameter, value and unit for one place, each answered by check_value, with each held limit sent once and a count of the rows over. A row that cannot be read (an unknown parameter, a value below detection such as <0.005) gets its own coded refusal.
verify_claimWhether a limit held says what a sentence says (an AI's answer, a report): confirmed with the row's cite, contradicted with the numbers held, or a refusal when nothing is held to judge it by.
list_sourcesEvery instrument held for a place: title, issuer, edition, what it governs, rows read, source URL and sha256.
get_permitOne US NPDES discharge permit from EPA's national file: limits by outfall, renewal due date, the last 12 months' values over a limit.
find_designationsThe status a species holds under each register held: US ESA, SARA and COSEWIC, provincial and territorial acts, IUCN Red List, CITES, CMS, EU Habitats and Birds Directives, UK schedules. Each cited to the line the register prints.
screen_speciesA species list in one call: up to 500 names for one place or everywhere, each answered by find_designations, with each register sent once and the registers that are silent on a name.
map_to_darwin_coreThe Darwin Core term each column of a species occurrence or checklist file maps to, the rule that decided it, and the GBIF-required terms no column carries.
searchFree-text search over everything held (a substance and a place, a species, an instrument's title, an NPDES permit number), returning ids for fetch.
fetchOne document search returned, as text: every cited row for a parameter in a place, what each register says about a species, or what is held for a place.

All tools are read-only and idempotent.

Example

curl -s -X POST https://passage-data.com/mcp \

-H "content-type: application/json" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"find_limits","arguments":{"parameter":"ammonia","place":"US-OH","medium":"surface_water"}}}'

or over plain HTTP:

curl -s "https://passage-data.com/api/v1/limits?parameter=ammonia&place=US-OH&medium=surface_water"

A lab table or a species list goes in one POST:

curl -s -X POST https://passage-data.com/api/v1/check -H "content-type: application/json"   -d '{"place":"CA-QC","medium":"water_discharge","rows":[{"parameter":"copper","value":0.15,"unit":"mg/L"},{"parameter":"zinc","value":0.4,"unit":"mg/L"}]}'

curl -s -X POST https://passage-data.com/api/v1/designations -H "content-type: application/json" -d '{"place":"CA-ON","species":["Myotis lucifugus","Emydoidea blandingii"]}'

Each row carries value, unit, statistic, direction, kind, medium, place, conditions as printed, and a cite block (instrument, title, issuer, edition, section, page, quote, source_url, source_sha256). More in examples/.

What is held

The live counts are on the service card: passage-data.com/api/v1/ (held). On 2026-10-14 the card said 247 instruments, 98,587 rows, 5,910 parameters and 74 places, plus 34 species registers holding 213,742 entries.

Terms

  • The data is read from public law and public agency files. Check the cited source before relying on a value. A refusal is a statement about our sources, not about the law of a place or the protection of a species.
  • Free while in preview. Calls are rate-limited (30 requests per 10 seconds per caller; a blocked call gets HTTP 429 with Retry-After).
  • We keep what is asked (tool, place, parameter or species name, outcome), the name and version the calling program gives, the network it calls from (operator and country, as Cloudflare reports them) and how many distinct callers a day; never an IP address, an account or a person.

This repository holds the server's listing and examples. The server itself is hosted at passage-data.com; its code is not public.
