MCP tools · 11 exposed · ~1,865 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
construction_injury_statistics ~120

Return a retained HSE series for construction in Great Britain: worker deaths and the rate per 100,000 workers with the long-run trend, kinds of fatal accident such as falls from height, employee deaths, self-reported and RIDDOR-reported injuries, or work-related ill health. Preserves each series’ period, units, provisional or revised status, confidence intervals, source file and publication date. This does not query a live HSE feed.

NameTypeReqDescription
seriesstring–Dataset series to return; defaults to the latest headline figures.
NameTypeReqDescription
limitstring–What it does not establish.
sourceobjectyes–
summarystringyesThe answer, figure or code first.

No examples provided.

ewc_search ~200

Find UK List of Waste (EWC) codes for a waste, skip or load from one to three material words such as “plasterboard”, “mixed rubble” or “contaminated soil”, from one or more codes, or from a code prefix. Search each material separately, not a sentence; match says how many words the result covers, and a weak match returns no waste. Returns official entries with hazardous and mirror status, partner codes, source lineage and any assessment needed. Use the returned entries as candidates: origin, process and composition still determine the classification. To start a note with chosen codes, pass them to start_document.

NameTypeReqDescription
limitinteger–Maximum matched waste groups and official entries to return; defaults to 5.
querystringyesOne to three material words, one or more EWC/LoW codes, or a code prefix; common spaced, hyphenated and unspaced formats are accepted.

limitstring–What it does not establish.
sourceobjectyes–
summarystringyesThe answer, figure or code first.

No examples provided.

fill_transfer_note ~297

Fill in a UK waste transfer note from what the person has said. Returns what the law still needs before signing, a card to correct every detail, and a link that opens the note unsigned on complyonsite.com, where both sides sign and save the PDF. Pass only details the person gave; never invent a name, address or registration number. Call again with the same details plus any new ones. Non-hazardous codes only; a hazardous load uses start_document. Saves, signs and sends nothing.

NameTypeReqDescription
codesarray–Non-hazardous EWC codes from ewc_search, up to 5.

first_aid_requirements ~207

Estimate first-aid cover for each shift from HSE guidance: how many first-aiders or appointed persons, which course, whether the first-aiders already there are enough, and whether a first-aid room is worth having. Construction site by default; also factory, office, shop, nursery (EYFS) and school. Returns roles, training, shortages, practical steps, factors, source lineage and a calculator link with the same inputs. This starts a workplace needs assessment; it is not a statutory staffing quota.

NameTypeReqDescription
factorsarray–Relevant factor ids returned by this tool for the selected workplace.
firstAidersAvailablearray–First-aiders already available on each shift, in the same order.
receptionClassboolean–For a school: whether it has a reception or nursery class.

sourceobjectyes–
summarystringyesThe answer, figure or code first.

No examples provided.

havs_daily_exposure ~164

Calculate one person’s daily hand-arm vibration (HAVS) exposure from the tools they use and for how long: A(8), HSE points, low/high range, and whether it passes the action value (2.5 m/s² A(8), 100 points) or the limit value (5 m/s², 400 points). For each tool give its own vibration figure in m/s², or an HSE category and variant to use HSE’s typical figure and range. Time means trigger time: the tool running in the person’s hands. Returns a link that opens the same calculation in the HAVS calculator.

NameTypeReqDescription
toolsarrayyesTools or tasks used by one person during one day; 1 to 20 entries.
NameTypeReqDescription
limitstring–What it does not establish.
sourceobjectyes–
summarystringyesThe answer, figure or code first.

No examples provided.

noise_daily_exposure ~233

Calculate one person’s daily noise exposure (LEP,d) from measured task levels (LAeq in dB(A)) and how long each lasts, or from dosemeter readings, and which action value it reaches (80 and 85 dB(A)). Optionally gives the weekly LEP,w, compares peak dB(C), and estimates noise at the ear against the 87 dB(A) limit from hearing protection SNR or H/M/L with each task’s C-weighted level. Do not use sound power LwA or per-shot values; omitted peak or protection measurements remain explicitly unassessed. Returns a link that opens the same calculation in the noise calculator.

NameTypeReqDescription
peaknumber–Highest measured C-weighted peak sound pressure level in dB(C).
protector––Hearing-protector attenuation from its SNR or H/M/L ratings.
tasksarrayyesMeasured tasks for one person in one day; 1 to 10 entries.

sourceobjectyes–
summarystringyesThe answer, figure or code first.

No examples provided.

power_tool_types ~122

Return how much a type of power tool vibrates and how loud makers declare it, such as an angle grinder, SDS drill or breaker: the median and spread of declared figures across models, the matching HSE vibration category and variants, and HSE in-use noise comparisons where available. Omit type to list the types. It does not return maker-model rows or quotes; declared LpA is not measured task LAeq.

NameTypeReqDescription
typestring–Tool-type slug returned by this tool, for example angle-grinder; omit to list all available types.
NameTypeReqDescription
limitstring–What it does not establish.
sourceobjectyes–
summarystringyesThe answer, figure or code first.

site_tools ~99

List the ComplyOnSite website tools for work on a file or kept record: safety data sheet to Excel, Receipt of Waste workbook check, Defra report from a weighbridge export, RAMS review, paper form to phone form, site diary, issues, progress report and register. Returns each tool’s link and what it needs. This server does not read files.

NameTypeReqDescription
querystring–Words for the job; omit for every tool.
NameTypeReqDescription
limitstring–What it does not establish.
sourceobjectyes–
summarystringyesThe answer, figure or code first.

No examples provided.

start_document ~99

Return an anonymous complyonsite.com link that opens a waste transfer note, hazardous waste consignment note or RAMS ready to fill in, plus the blank template and a worked example as ready-made PDFs. Waste-note links prefill validated EWC codes; RAMS links select a job and optional supported operation. The person completes, signs and downloads the document on the site. The tool does not create, save, sign, issue or submit a document.

Input schema present but exposes no named parameters.

systemstringyesWhich list to search.
NameTypeReqDescription
limitstring–What it does not establish.
sourceobjectyes–

waste_paperwork ~219

Return which paperwork a waste movement needs: in the UK from the nation and whether the waste is hazardous, or any listed document by id, including Ireland, the Netherlands, the US, Canada and Australia. A document id takes precedence when both forms are supplied. Results cover the document, parties, the items the preparation tool asks for, retention, pre-notification where it applies, electronic and signature status, regulator route, the ComplyOnSite tool that prepares it, and source lineage. Preparation tools do not issue, submit or confirm acceptance of official documents.

NameTypeReqDescription

Common questions

What is the ComplyOnSite MCP server?

ComplyOnSite is an MCP server listed in the public MCP registry as com.complyonsite/tools. Waste codes, transfer notes filled in from chat, HAVS, noise and first-aid calculators. This page covers its hosted endpoint (https://mcp.complyonsite.com/mcp).

Is the ComplyOnSite MCP server safe to use?

ComplyOnSite scores 82 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the ComplyOnSite MCP server expose?

ComplyOnSite exposes 11 tools: ewc_search, first_aid_requirements, havs_daily_exposure, noise_daily_exposure, construction_injury_statistics, and 6 more. Their descriptions and schemas cost roughly 1,865 tokens of context every time the server is loaded.

Does the ComplyOnSite MCP server require authentication?

No. We connected to ComplyOnSite without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the ComplyOnSite MCP server still maintained?

ComplyOnSite is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
