Evlek MCP Server

Name: Evlek — Northern Cyprus Property MCP Server
Author: evlek

AI-native property discovery for North Cyprus (KKTC). Built on the Model Context Protocol — works in Claude, ChatGPT, Gemini, Cursor, and any MCP-compatible client.

The Evlek MCP server gives AI agents structured, real-time access to North Cyprus property data — search active listings, compare cities and districts, and track the price index. All data is sourced live from evlek.app. Evlek does not offer a rental-yield or investment-return estimate: figures are descriptive asking-price facts only, never a valuation, forecast, or recommendation. Title-deed (koçan) and legal-procedure tools are deliberately not part of the surface: that taxonomy has not passed an independent KKTC legal audit.

Why Evlek MCP

AI-first. Built for agentic workflows from day one — not retrofitted on a legacy listing API.
Multilingual. Answers in TR, EN, RU, DE, AR: pass locale (or write the search query in that language) and the text, amenity names, number formats and links follow it. Place names are resolved in any of the five languages.
Verification-aware listings. Evlek surfaces listing and account verification context where available, and the MCP omits contact fields to preserve Evlek's reveal/contact funnel.
Built for the region. Optimized for the 6 cities of North Cyprus (Lefkoşa, Girne, Gazimağusa, İskele, Güzelyurt, Lefke) and 100+ districts.
Production-grade. OWASP MCP Top 10 aligned — Zod input validation, output sanitization, rate limiting (60/min/IP, 500/min global), Sentry observability.

Quick start

Remote-capable clients (preferred)

Most modern MCP clients (Claude, Cursor, VS Code) connect directly to the Streamable HTTP endpoint — no local bridge needed:

json

{
  "mcpServers": {
    "evlek": {
      "url": "https://evlek.app/api/mcp"
    }
  }
}

ChatGPT (connector + Deep Research)

Add https://evlek.app/api/mcp as a custom connector. Evlek exposes OpenAI-compatible search and fetch tools, so it works in ChatGPT connectors and Deep Research in addition to developer mode.

Claude Desktop (legacy stdio bridge)

If your client only supports stdio servers, use the pinned mcp-remote bridge. Add this to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

json

{
  "mcpServers": {
    "evlek": {
      "command": "npx",
      "args": ["-y", "mcp-remote@0.1.16", "https://evlek.app/api/mcp"]
    }
  }
}

Restart Claude Desktop. The "evlek" server appears in the tools list.

MCP Inspector (test before installing)

bash

npx @modelcontextprotocol/inspector https://evlek.app/api/mcp

Direct API (cURL)

bash

curl -X POST https://evlek.app/api/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Local stdio server (this repository)

This repo is also a runnable MCP server. It answers initialize / tools/list entirely locally from the embedded tool contract (tools.json) and fetches live data from the Evlek data API when a tool is called. It only implements tools — it does not declare the resources or prompts capability, so resources/list and prompts/list return a normal MCP "method not found" error on this bridge; those primitives (see below) are hosted-endpoint-only, reachable via the Streamable HTTP URL above. It also speaks whatever MCP protocol version the pinned @modelcontextprotocol/sdk supports during initialize (currently 2025-11-25), not necessarily the hosted endpoint's 2026-07-28 — tool schemas are identical either way.

bash

npx github:Evlek/evlek-mcp        # or: npm install && npm start

json

{
  "mcpServers": {
    "evlek": {
      "command": "npx",
      "args": ["-y", "github:Evlek/evlek-mcp"]
    }
  }
}

Smoke-test it (spawns the server and speaks real MCP over stdio):

bash

npm test              # live: initialize + tools/list + a real tools/call
OFFLINE=1 npm test    # offline: introspection works with zero network

Available tools

8 tools · protocol 2026-07-28 · Streamable HTTP JSON-RPC 2.0

Tool	Title	Description
`search_listings`	Search Northern Cyprus property listings	Use this when the user wants to find or see property listings; results are shown with real photos in the Evlek widget. Search live Evlek property listings for sale and long-term rent in Northern Cyprus (KKTC/TRNC; prices in GBP unless a currency is given; 2+1 means bedrooms 2) with structured filters: transaction, city, district, property type, bedrooms, price, areas, amenities, nearby university. Pass the user's language as `locale` (tr\|en\|ru\|de\|ar): the text, amenity names, number formats and links follow it. Returns at most 10 listings per call, each as one readable line (type, place, price, rooms, area, a deterministic sentence, data notes, canonical link) plus a structured card; continue with the `nextCursor` of a group. Without `transaction`, listings for sale and for rent come as two separate groups, each with its own cursor that is only valid together with that group's transaction. Place names in any language are resolved; an unknown place returns suggestions instead of results. An amenity that cannot be filtered on is reported as not applied. For one listing use `get_listing`. Returns advertised asking-price and listing facts only: not a valuation, verification of property-specific claims, forecast, ranking or recommendation.
`search`	Search Evlek property listings	Use only for research and citation lookups (deep research). To show listings to the user, use search_listings instead. Search live Northern Cyprus (KKTC/TRNC) property listings on Evlek with a free-text query in Turkish, English, Russian, German or Arabic. Returns matching listings as id/title/url for the fetch tool, newest first (sale and rent as two groups when the query names neither). The answer language follows the language of the query. Same data as search_listings: this fixed form exists for the ChatGPT/OpenAI connector contract. Use when: the caller only has a free-text query ("2+1 apartment in Kyrenia under 150000 pounds", "EVL-100464"). Don't use for: structured filters, paging or another answer language: use search_listings.
`fetch`	Fetch full Evlek listing detail	Fetch the full detail of one Evlek listing: title, price, location, rooms, areas, amenities, data-quality notes and the canonical link. The id is the listing id (UUID) from a search result, a listing number such as EVL-100464, or an evlek.app listing link; the answer language follows the link (English otherwise). A listing that is not available (it does not exist, is not public, or was removed) always gets the same answer. Same data as get_listing: this fixed id-only form exists for the ChatGPT/OpenAI connector contract. Use when: an id from search is known. Don't use for: discovery (use search first) or another answer language (use get_listing).
`get_listing`	Get an Evlek listing	Get the full details of ONE public Evlek listing (sale or long-term rent) in the user's language. `ref` is the listing id (UUID), the listing number (EVL-100464 or just 100464) or an evlek.app listing link in any language. Returns the price, rooms, bathrooms, built area and plot area (always separate), the approximate location, features, the office name, dates, data-quality notes, photos with captions where they exist, AI virtual-staging before/after images when the office approved them (always labelled as AI-generated) and the canonical link. Contact details are never included: send the user to the link. A listing that is unknown or no longer public answers found:false with code NOT_FOUND (this is not an error). Pass the user's language as `locale` (tr, en, ru, de or ar).
`compare_listings`	Compare Evlek listings	Compare 2 to 4 public Evlek listings side by side in the user's language: price, price per m² (only when the built area is believable), rooms, bathrooms, built area and plot area (always separate), location, furnishing, key features and data-quality notes, plus a few descriptive highlights (lowest price, largest indoor area, most recently listed). `ids` takes listing ids (UUID), listing numbers (EVL-100464) or evlek.app listing links, in any mix; the order you give is kept. Sale and rent listings are never ranked against each other: a mixed request is shown in two groups with a warning. A reference that is unknown or no longer public is listed in `missingIds` with code NOT_FOUND (this is not an error). Descriptive facts only: no valuation and no recommendation. Pass the user's language as `locale` (tr, en, ru, de or ar).
`market_stats`	Northern Cyprus market statistics	Market statistics for Northern Cyprus from asking prices of active public listings (not sales, valuations or forecasts). No city = the island by city; one city = its districts; several = side by side; city + district = a district profile. Sale and rent are reported separately. Each figure has activeCount (public listings in scope) and sampleCount (the cleaned sample behind the statistic); below 10 sampled listings it is withheld. Pass locale.
`list_locations`	List Evlek locations	List the places Evlek knows in Northern Cyprus (6 cities, districts, villages, sub-areas, landmarks, the Karpaz region) with their public sale and long-term rent listing counts. Call it first when unsure how a place is spelled: every name and id returned is accepted by the other tools. Pass `city` (any spelling or language) for one place in detail. Names are Turkish or Latin; Russian, German and Arabic spellings are accepted as input but not listed.
`convert_currency`	Currency conversion (GBP/EUR/USD/TRY)	Converts an amount between GBP, EUR, USD and TRY with the exchange rates Evlek stores (refreshed daily) and returns all four equivalents. Currency conversion only: no payment plan, deposit or instalment schedule, tax, fee or acquisition-cost estimate, no advice. Rates older than 24 hours are flagged as stale; beyond 72 hours (or when none are stored) no conversion is produced (FX_UNAVAILABLE).

Every tool declares annotations: { readOnlyHint: true, destructiveHint: false, openWorldHint: false } — the whole surface is read-only.

Interactive widgets (MCP Apps / SEP-1865)

Five tools additionally bind a sandboxed HTML view (_meta.ui.resourceUri) that MCP Apps-capable hosts (Claude web/desktop) render inline in the conversation:

Tool	Widget	What you get
`search_listings`, `search`	`ui://evlek/listing-cards-v3-5.html`	Listing cards (cover photo, price, location); opening one shows the listing detail view; in ChatGPT, "Show on map" opens a full-screen map of every match
`get_listing`, `fetch`	`ui://evlek/listing-detail-v3-5.html`	Photo gallery, spec sheet, and AI virtual-staging before/after (always AI-disclosed)
`market_stats`	`ui://evlek/price-index-v3-4.html`	Asking-price statistics per city / district

compare_listings, list_locations and convert_currency have no widget. The widget URIs moved from -v2 to -v3 in 3.0.0 so a host never serves a cached v2 template against v3 data. 3.0.1 moved them to -v3-1, 3.0.2 to -v3-2, 3.0.3 to -v3-3 and 3.1.0 to -v3-4 (cards and detail then -v3-5); the older v3 URIs keep answering with the current content. Rule since 3.1.0: a widget's content never changes under a URI it was published with (a host caches a template by URI), so a changed widget gets a new URI.

In ChatGPT (3.0.2, search since 3.0.3) the listing data reaches the widget through the result _meta["evlek/widget"], which ChatGPT shows only to the widget; for search_listings and get_listing the model gets a short summary (counts, price range, listing numbers). Other clients get the full structuredContent as before.

Views are static, self-contained HTML — no bundler, no third-party JS. Listing data reaches them only at runtime over postMessage and is written with textContent, never innerHTML. CSP is declared per resource (_meta.ui.csp) and limited to the public listing-photo origin.

See TOOLS.md for full input schemas, parameter details, and response examples.

Resources (12) & resource templates (2)

resources/list returns 12 resources on the hosted endpoint — 9 read-only evlek:// data resources plus the 3 ui:// interactive-widget resources described above (pre-declared so a host can pre-cache them). Parameterized templates are separate, via resources/templates/list:

Templates (2): evlek://price-index/{city} · evlek://district/{city}/{district}
Data resources (9): per-city price indexes (girne, iskele, lefkosa, gazimagusa, guzelyurt, lefke), a sample district profile (Girne/Alsancak), and 2 orientation guides — evlek://guides/neighborhood-personas, evlek://guides/universities.
Widget resources (3): ui://evlek/listing-cards-v3-5.html, ui://evlek/listing-detail-v3-5.html, ui://evlek/price-index-v3-4.html — see "Interactive widgets" above.

Renamed tools in 3.0.0 (deprecated aliases)

3.0.0 consolidates the 12 v2 tools into 8. The old names below are not in tools/list any more, but the hosted endpoint still answers them for one release: the call is translated to the new tool, runs it, and the result starts with a Deprecated: … Use <new> instead. line (plus structuredContent.deprecated). The aliases are removed in 3.1.0 — switch to the new names now.

Old name (v2)	New name (3.0.0)	Argument change
`get_listing_detail`	`get_listing`	`propertyId` / `property_id` → `ref`
`get_listing_by_number`	`get_listing`	`listingNumber` / `listing_number` → `ref`
`compare_properties`	`compare_listings`	`listingIds` / `listing_ids` → `ids`
`get_price_index`	`market_stats`	`city` kept; `type` → `transaction` (default `sale`)
`compare_cities`	`market_stats`	`cities` → `city`; `type` → `transaction` (default `sale`)
`get_district_profile`	`market_stats`	`city`, `district` kept
`payment_plan`	`convert_currency`	`price` → `amount` (name stays reserved for a future instalment tool)

Unchanged names: search_listings, search, fetch, list_locations, convert_currency. search_listings, list_locations and convert_currency gained new parameters and canonical names (e.g. transaction, priceMin/priceMax, sort, cursor, amount, locale) — see TOOLS.md. The v2 names type, maxPrice and price are still accepted on the hosted endpoint. Tools removed in 2.0.0 and earlier (get_yield_estimate, suggest_neighborhood, student_housing, get_market_overview, get_legal_info) still return a protocol error naming the replacement, not an alias.

Architecture

The Evlek MCP server runs as a hosted endpoint at https://evlek.app/api/mcp. It speaks the Model Context Protocol over Streamable HTTP (JSON-RPC 2.0), protocolVersion 2026-07-28, and exposes tools, resources, resource templates, and prompts. Discovery metadata is published at /.well-known/mcp.json.

This repository contains:

server.json — MCP Registry manifest
tools.json — Live tool contract (what the local stdio server answers tools/list with)
TOOLS.md — Full tool reference (JSON schemas + examples)
CHANGELOG.md — Notable changes to the tool surface, including removed/renamed tools
examples/ — Configuration files for Claude Desktop, Cursor, VS Code
CONTRIBUTING.md — How to file issues and propose docs improvements

Sözleşme dosyaları (contract files)

tools.json and TOOLS.md are a projection of the live server, generated by pnpm mcp:export-public in the source repo and copied here verbatim. Never hand-edit them; the Contract Drift workflow compares tools.json against the live tools/list daily and on every PR.
server.json is not that projection. It is the MCP Registry publish manifest and must keep the registry shape: name is app.evlek/mcp-server (pattern ^[a-zA-Z0-9.-]+/[a-zA-Z0-9._-]+$) and description is at most 100 characters. A sync only updates its version, the tool count in description, and the _meta tool list. (Copying the export's own server.json here is what failed the v2.1.0 registry publish.)

The full server implementation (database schemas, API routes, AI prompt engineering, listing pipeline) is hosted at evlek.app and remains proprietary.
