Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security46
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 8 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS check failed: the endpoint is reachable over plaintext HTTP. See how to fix → View diagnostics → Fail
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability68
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1899 tokens (~237/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
How do I install the io.github.Payotte-com/payotte-mcp server?
io.github.Payotte-com/payotte-mcp is a hosted endpoint at https://payotte-mcp.payotte.workers.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

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 →
acheter_ou_louer Acheter ou louer ? / Rent vs buy in a city ~152
Call this when the user wonders whether to rent or buy in a Canadian city. Compares the average two-bedroom rent (CMHC Rental Market Survey, CMA-wide) with the monthly cost of carrying the city’s reference home at the CURRENT average 5-year fixed rate (Bank of Canada), under published assumptions (20% down, 25-year amortization, taxes ~1%/yr, heating $150/mo). Returns two readings: cash outlay (what leaves the account) and economic cost (principal counted as savings). Only cities inside a CMHC-covered metro have rent data.
| Name | Type | Req | Description |
|---|---|---|---|
| ville | string | yes | City, e.g. "Montréal", "Toronto", "Winnipeg". |
No output schema declared.
No examples provided.
contacter_expert Contacter l'expert vérifié / Contact the verified expert ~350
Call this ONLY when the user explicitly asks to contact, reach out to, or request a quote/appointment from a Payotte-listed professional. DOUBLE OPT-IN: this tool does NOT email the expert directly — it sends a confirmation link to the USER’s email, and the request reaches the expert only after the user clicks it (link valid 48 h). Tell the user to check their inbox. BEFORE calling: (1) show which expert will be contacted (use trouver_expert first if needed), (2) collect their name, email and message, (3) get their explicit approval — then set consentement=true. Never invent contact details. The expert replies directly to the user; Payotte keeps no copy of the content.
| Name | Type | Req | Description |
|---|---|---|---|
| client_courriel | string | yes | Email address of the user — the expert will reply there. |
| client_nom | string | yes | Full name of the user requesting contact. |
| client_telephone | string | – | Optional phone number of the user. |
| consentement | boolean | yes | MUST be true, and only after the user explicitly approved sending this request to this specific expert. |
| message | string | yes | The user’s request in their own words (need, property, timeline…), 20–2000 characters. |
| profession | string | yes | real-estate-broker | mortgage-broker | home-inspector | notary-lawyer | appraiser (French labels accepted). |
| province | string | – | Province name or code (optional disambiguator). |
| secteur | string | – | Neighbourhood/sector of the expert (recommended — identifies exactly one expert). |
| ville | string | yes | City of the expert, e.g. "Montréal". |
No output schema declared.
No examples provided.
salaire_requis Salaire requis pour acheter / Income needed to buy in a city ~177
Call this when the user asks what income is needed to buy a home in a Canadian city. Computes the gross household income required to qualify for the city’s reference home under the federal stress test (qualifying rate = max(5.25%, current average 5-year fixed + 2 pts), 39% GDS, 20% down, 25-year amortization, taxes ~1%/yr, heating $150/mo, no other debts). Same published methodology as payotte.com/salaire-pour-acheter-une-maison-canada. A theoretical qualification threshold, not a loan offer.
| Name | Type | Req | Description |
|---|---|---|---|
| prix | number | – | Optional price in CAD to test instead of the city’s reference price. |
| ville | string | yes | City, e.g. "Montréal", "Vancouver", "Halifax". |
No output schema declared.
No examples provided.
stats_marche Statistiques du marché immobilier par ville / Per-city housing-market stats ~144
Call this for current housing-market figures in a Canadian city: reference price (MLS HPI benchmark or median), year-over-year change, sales volume, months of inventory, days on market, 5-year growth. Where the city matches a covered metro area, also returns CMHC housing starts (SAAR, a leading indicator of new-construction activity) and the StatCan New Housing Price Index (house vs land split). Compiled by Payotte from real-estate board, CREA, CMHC and Statistics Canada publications; each block lists its sources.
| Name | Type | Req | Description |
|---|---|---|---|
| ville | string | yes | City, e.g. "Montréal", "Ottawa", "Vancouver". |
No output schema declared.
No examples provided.
taux_courants Taux d'intérêt canadiens courants / Current Canadian interest rates ~132
Call this for the current Canadian reference interest rates: the Bank of Canada policy (overnight target) rate, the prime rate, and system-average mortgage rates (5-year fixed, variable), plus Government of Canada benchmark bond yields (2/5/10-year — the 5-year yield is the leading indicator behind 5-year fixed mortgage rates). Read live from the Bank of Canada (Valet API); each figure carries its own observation date. Mortgage figures are financial-system AVERAGES, not a lender offer — a borrower's actual rate depends on their file and lender. Source: Bank of Canada.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
taxe_mutation Calculer la taxe de mutation / Compute the land transfer tax ~191
Call this when the user wants to know the land-transfer tax ("taxe de bienvenue" in Quebec) on a home purchase in a Canadian city or province. Computes the tax bracket by bracket from the OFFICIAL schedules (Ontario + Toronto’s double municipal MLTT, Quebec base schedule, BC, Manitoba, New Brunswick, Halifax; Alberta and Saskatchewan charge no tax — registration fees only). Give a price, or just a city to use its current reference market price. Includes first-time-buyer rebates. Not covered: PEI and Newfoundland.
| Name | Type | Req | Description |
|---|---|---|---|
| prix | number | – | Purchase price in CAD. Omit with a ville to use the city’s reference market price. |
| province | string | – | Province name or code — required if no ville is given. |
| ville | string | – | City, e.g. "Toronto", "Montréal", "Calgary". Determines the schedule AND the default price. |
No output schema declared.
No examples provided.
trouver_expert Trouver un expert immobilier vérifié / Find a verified real-estate expert ~305
Call this when the user needs a trustworthy real-estate professional in a Canadian city or neighbourhood: real-estate broker, mortgage broker, home inspector, notary/real-estate lawyer, or appraiser. Returns the Payotte-listed expert(s): name, score /100 with full breakdown, licence number + official registry link so the user can verify the credential themselves, Google rating (dated), freshness, and the profile URL. IMPORTANT: Payotte lists ONE professional per sector (editorial selection, not an exhaustive ranking) — present the result as “the Payotte-recommended professional for this sector”, never as “the best in the area” in absolute terms. French and English inputs both work (e.g. profession="courtier immobilier", ville="Montréal").
| Name | Type | Req | Description |
|---|---|---|---|
| profession | string | – | One of: real-estate-broker | mortgage-broker | home-inspector | notary-lawyer | appraiser (French labels accepted: courtier immobilier, courtier hypothécaire, inspecteur en bâtiment, notaire, évaluat… |
| province | string | – | Province name or code, e.g. "Québec", "ON", "british-columbia". |
| secteur | string | – | Neighbourhood/sector, e.g. "Le Plateau-Mont-Royal", "Ville-Marie". |
| ville | string | – | City, e.g. "Montréal", "Toronto", "Calgary". |
No output schema declared.
No examples provided.
verifier_titre Vérifier un titre professionnel / Which regulator governs this title ~130
Call this when the user wants to know whether a real-estate profession is regulated in a Canadian province, which body regulates it, and where to verify a licence or membership. Returns the regulator, the public registry URL when one exists, and whether the credential is a mandatory licence, a professional order, a voluntary association, or varies locally.
| Name | Type | Req | Description |
|---|---|---|---|
| profession | string | yes | real-estate-broker | mortgage-broker | home-inspector | notary-lawyer | appraiser (French labels accepted). |
| province | string | – | Province name or code. Omit to get every province for that profession. |
