# Smarter Weather Developer Platform > Weather data for apps and AI agents: a REST API (api.smarterweather.com), a > hosted weather MCP server (mcp.smarterweather.com/mcp), and an agent-first > onboarding MCP server (developers.smarterweather.com/mcp) that can sign you > up, mint API keys, and configure your client — all from inside an AI agent. Agents onboarding a developer should start with the onboarding MCP server: connect anonymously to https://developers.smarterweather.com/mcp (Streamable HTTP, no credentials) and call get_plans / get_documentation / sign_up. Account-scoped tools (API key minting, billing) unlock after OAuth 2.1 sign-in. ## Machine-readable contracts - [OpenAPI specification](https://developers.smarterweather.com/openapi.yaml): full machine-readable contract for api.smarterweather.com - [Weather MCP tool descriptors](https://developers.smarterweather.com/.well-known/mcp-tools.json): the 28-tool catalog for mcp.smarterweather.com - [Agent Skills index](https://developers.smarterweather.com/.well-known/skills/index.json): installable SKILL.md skills for this platform - [smarterweather-api skill](https://developers.smarterweather.com/.well-known/skills/smarterweather-api/SKILL.md): REST integration guidance for agents - [smarterweather-mcp skill](https://developers.smarterweather.com/.well-known/skills/smarterweather-mcp/SKILL.md): MCP install, onboarding flow, x402 keyless access ## Docs - [Built for agents](https://developers.smarterweather.com/agents): one-click MCP installs, onboarding flow, agentic payments - [Quickstart](https://developers.smarterweather.com/quickstart): mint a key and make your first REST and MCP calls - [REST API guide](https://developers.smarterweather.com/api): auth, endpoints, rate-limit headers - [API reference](https://developers.smarterweather.com/api/reference): interactive reference rendered from the OpenAPI spec - [Weather MCP server guide](https://developers.smarterweather.com/mcp-server): hosted endpoint, tool catalog, stdio bridge (@smarterweather/mcp-weather) - [MCP setup guide](https://developers.smarterweather.com/mcp-server/setup): client configuration for Cursor, Claude Code, VS Code, and others - [MCP tool reference](https://developers.smarterweather.com/mcp-server/tools): per-tool inputs and outputs - [Developer pricing](https://developers.smarterweather.com/pricing): tiers, quotas, and keyless (x402) pay-per-call - [Error model](https://developers.smarterweather.com/api): RFC 7807 problem details and retry semantics ## Optional - [Public developer repo](https://github.com/smarterweather/developer): mirrored contracts, guides, and issue templates - [Developer terms](https://developers.smarterweather.com/legal/terms) - [Acceptable use](https://developers.smarterweather.com/legal/acceptable-use)
