Security Report

5.2

Moderate5.2Moderate Risk

FairePlace is a well-architected MCP server for French rental tools with clear security boundaries and intentional design. The server is a thin stateless proxy to public APIs with no authentication required, which is appropriate for its public data/document generation purpose. Code quality is high with proper input validation via Zod schemas, no dangerous patterns detected, and permissions are well-scoped to the server's stated function. Minor findings around error handling and sensitive data logging do not materially impact security. Supply chain analysis found 9 known vulnerabilities in dependencies (2 critical, 4 high severity).

FairePlace — Public MCP Server 🏠🇫🇷

A public, no-auth, remote MCP server that exposes FairePlace's free French residential rental tools to AI agents (ChatGPT, Claude, Perplexity, Cursor…): create & e-sign a lease (bail), check rent control, revise rent (IRL), compute a security deposit or rental yield, get an address risk report, and generate rental documents (rent receipts, inventory, notices, and more).

Zero LLM inference server-side. The server is a thin, deterministic proxy over FairePlace's public API — the calling agent pays for its own inference; FairePlace only runs Rust/Typst logic. Marginal cost ≈ 0.

Endpoint: https://mcp.faireplace.com/mcp · Registry: com.faireplace/public-tools

Quick start

Add the remote server to any MCP client:

Client	How
Claude (Desktop / claude.ai)	Settings → Connectors → Add custom connector → `https://mcp.faireplace.com/mcp`
Cursor	Settings → MCP → Add → Streamable HTTP → `https://mcp.faireplace.com/mcp`
ChatGPT (Custom GPT)	Import the OpenAPI at `https://mcp.faireplace.com/openapi.json` as an Action (auth: none)
MCP Inspector	`npx @modelcontextprotocol/inspector@latest` → connect to the URL

No API key, no account. Ask your agent things like "Check if a 1500 €/month rent is legal at 75001 Paris for a 45 m² 2-room" or "Create a furnished lease for a flat in Paris at 850 €".

Tools (21)

Data & compliance (return JSON):

Tool	Purpose
`check_rent_control`	Rent control verdict for an address (encadrement des loyers)
`get_reference_rent`	Reference rent (€/m²) for a rent-controlled quarter
`simulate_irl` / `simulate_irl_by_quarters`	Annual rent revision (IRL), explicit or server-resolved INSEE values
`calculate_deposit_restitution`	Security-deposit cap, restitution deadline, penalties
`simulate_rental_yield`	Gross/net yield + per-regime taxation (LMNP, micro-foncier…)
`check_address_risks`	Natural/technological risk report (Géorisques)

Lease creation (the conversion tool):

Tool	Purpose
`create_lease_draft`	Create a lease draft → returns a link to finalize & e-sign it (advanced eIDAS, PAdES-B-LT) on FairePlace

Document generation (return a link that renders the PDF): generate_quittance, generate_etat_des_lieux, generate_conge, generate_cautionnement, generate_avenant, generate_resiliation_amiable, generate_relance_impaye, generate_inventaire_mobilier, generate_notice_information, generate_reparations_locatives, generate_grille_vetuste, generate_charges_recuperables, generate_bordereau_restitution.

How the lease → signature flow works

agent → create_lease_draft(owner, logement, lease)
      → FairePlace stores an anonymous draft, returns draft_token
      → tool returns  https://mcp.faireplace.com/r?draft_token=…
user clicks the link
      → GET /r sets the draft_token cookie on .faireplace.com, 302 → app sign-up
      → on login, FairePlace ingests the draft and opens it on the Signature step

The server never hands back a signable document — signature stays behind FairePlace auth. Every link carries utm_source=mcp for attribution.

Architecture

Intentionally a thin adapter — not a domain application. All business logic (rent-control data, IRL indices, legal document rendering) lives in FairePlace's Rust backend; this Worker only maps MCP tool calls to the public /public/tools/* HTTP endpoints and formats results.

Runtime: Cloudflare Worker (McpAgent, Durable Object for session state).
Transport: Streamable HTTP on /mcp.
Guardrail: native per-IP rate limit (100 req / 60 s).
PDF delivery: /pdf/<slug>?p=<base64url payload> serves an HTML page that fetches the PDF browser-side (avoids a same-zone Worker→origin block; no storage — the PDF is a local blob).

Endpoints

Path	Purpose
`/mcp`	MCP server (Streamable HTTP)
`/openapi.json`	Curated OpenAPI 3.1 for GPT Actions
`/.well-known/ai-plugin.json`	Plugin manifest
`/llms.txt`	Passive AI discovery
`/r`	Draft-resume → sets cookie → sign-up
`/pdf/<slug>`	On-demand PDF rendering (browser-side)

Development

npm install
npm run typecheck
npm run dev            # wrangler dev (local)
npm run inspect        # MCP Inspector
npm run deploy         # wrangler deploy (needs Cloudflare auth)

Config lives in wrangler.jsonc (vars: API_BASE, WEB_BASE, SELF_BASE, DRAFT_REPRISE_URL, APP_SIGNUP_URL).
