MCP Svelte Docs

MCP Svelte Docs is a single, authoritative Model Context Protocol server that delivers up‑to‑date, TypeScript‑first documentation for every Svelte 5 and SvelteKit feature. By pulling definitions directly from the official TypeScript declaration files, it guarantees that developers receive exact syntax, parameter types, and return values rather than relying on potentially stale tutorials or community posts. This precision is essential when building complex applications, as it eliminates runtime errors caused by mismatched types or deprecated APIs.

The server exposes one powerful tool, , which accepts an identifier (such as or ) and a format specifier (, , or ). The response can be a terse TypeScript signature, a concise definition with an example, or a comprehensive guide complete with usage patterns and migration advice. With over 28 identifiers covering runes, event handling, lifecycle equivalents, and advanced patterns, the tool consolidates more than a dozen specialized resources into a single, consistent interface. This reduces cognitive load for developers and allows AI assistants to fetch any Svelte concept on demand without juggling multiple endpoints.

For real‑world workflows, the server shines in several scenarios. During code reviews or pair programming, an AI assistant can instantly supply the exact type signature of , ensuring that state dependencies are correctly annotated. When migrating a legacy Svelte 4 project, the identifier offers step‑by‑step guidance on replacing old APIs with their Svelte 5 counterparts. In teaching environments, educators can prompt the assistant for quick snippets that illustrate await expressions or remote functions, enabling students to experiment without leaving the IDE. The fuzzy‑matching and related‑concept suggestions further streamline discovery, helping newcomers find the right tool even if they misspell an identifier.

Integration with existing AI workflows is straightforward: any MCP‑compatible client can invoke as a normal tool call, and the server responds with structured JSON that can be rendered directly in chat or IDE panels. Because all responses are derived from the source TypeScript files, they stay in sync with Svelte releases automatically, giving developers confidence that their AI‑assisted documentation is always current. This combination of authoritative content, unified access, and tight integration makes MCP Svelte Docs a standout resource for anyone building or maintaining applications with Svelte 5 and SvelteKit.
