JSandy - RPC Service Framework

Analyze Code

Analyze a code snippet for @jsandy/rpc best practices. Runs all validation checks and provides recommendations based on the knowledge base.

Analyze Project Structure

Analyze a project structure for @jsandy/rpc integration. Identifies framework type, suggests file locations for route handlers, detects missing dependencies, and recommends project organization.

Check Zod V4 Compliance

Flag any Zod v3 syntax in code. @jsandy/rpc requires Zod v4. Detects deprecated methods like .nativeEnum(), .strict(), .passthrough(), .strip(), .deepPartial(), .merge(), z.promise(), .create(), z.ostring(), etc.

Create Client

Generate a typed @jsandy/rpc client setup using createClient. Produces TypeScript code that imports from @jsandy/rpc/client with full type inference.

Create Middleware

Generate typed @jsandy/rpc middleware with context accumulation. Produces TypeScript code that follows the middleware pattern with next() and context fields.

Create Procedure

Generate a typed @jsandy/rpc procedure definition (query or mutation). Produces ready-to-use TypeScript code with Zod v4 schemas.

Create Pubsub Adapter

Generate a PubSubAdapter implementation for @jsandy/rpc WebSocket scaling. Supports built-in adapters (Upstash Redis, Cloudflare Queue) or custom implementations.

Create Router

Generate a @jsandy/rpc router definition that groups procedures together. Produces TypeScript code with correct router() call and type export.

Create Ws Procedure

Generate a typed @jsandy/rpc WebSocket procedure with incoming/outgoing event schemas. Produces ready-to-use TypeScript code with Zod v4 schemas for real-time features.

Get Examples

Get usage examples for a specific @jsandy/rpc pattern. Returns code examples from the patterns library (auth, CRUD, file upload, pagination, etc.).

Hello

Says hello. Use this to verify the MCP server is working.

List Exports

List all exports from a specific @jsandy/rpc entry point. Shows every exported function, type, and constant.

Lookup Api

Look up a specific @jsandy/rpc API by name. Returns the full documentation including type signature, parameters, and usage examples. If not found, suggests similar entries.

Merge Routers

Generate a mergeRouters configuration that combines multiple sub-routers into a single Hono app. Produces TypeScript code with Hono setup, CORS, error handling, and router mounting.

Search Docs

Search @jsandy/rpc documentation by topic or keyword. Returns ranked results from API reference, guides, patterns, and export listings.

Suggest Improvements

Given existing @jsandy/rpc code, suggest improvements for correctness, performance, and best practices. Combines validation checks with goal-oriented recommendations.

Validate Middleware

Check @jsandy/rpc middleware for correct patterns. Detects missing next() calls, unreturned next() results, Zod v3 usage, and import issues.

Validate Nextjs Integration

Check a Next.js route handler for correct @jsandy/rpc integration. Detects missing GET/POST exports, incorrect app.fetch usage, Zod v3 patterns, and import issues.

Validate Procedure

Check a @jsandy/rpc procedure definition for correctness. Detects Zod v3 anti-patterns, incorrect builder chain order, bad import paths, and missing patterns.

Validate Router

Check a @jsandy/rpc router definition for structural issues. Detects empty routers, procedures without router wrappers, Zod v3 usage, and import path issues.
