Verified Safeby AdrielC
Overview
An OTP-first MCP server for car-buying tools, providing robust job orchestration, retries, rate limiting, and idempotency for external integrations.
Installation
mix run --no-haltEnvironment Variables
- LISTINGS_PROVIDER
- VIN_PROVIDER
Security Notes
The server explicitly uses environment variables for configuration (e.g., `LISTINGS_PROVIDER`, `VIN_PROVIDER`), avoiding hardcoded secrets. Future email sending features are designed with safety principles including domain allowlists, rate limits, and a default draft-only mode. External API calls (NHTSA vPIC for VIN decoding) introduce standard network risks, but no immediate malicious patterns are identified. The `stdio` transport for v1 is relatively contained for local usage, and the Elixir/OTP architecture promotes fault tolerance and isolation.
