Zod Adapter — simple-webmcp/zod

import 'simple-webmcp/zod'; // registers converter globally
import { zodToJsonSchema, convertZodDef } from 'simple-webmcp/zod';

• zodToJsonSchema(schema) → JsonSchema|null (checks _def/_zod).
• convertZodDef(z) → JsonSchema (internal).
• Handles ZodString (min/max/regex/email/url/uuid), ZodNumber (min/max/int), ZodBoolean, ZodEnum, ZodObject (shape, optional detection), ZodArray, ZodUnion, etc.

Without import, core falls back to {type:'string'} placeholder for StandardSchema fields and inferred for whole schema.

import { webmcp } from 'simple-webmcp';
import 'simple-webmcp/zod';
import { z } from 'zod';
webmcp(fn, { schema: z.object({ query: z.string() }) }); // → JSON Schema via adapter

Keep core lean — dist/zod.js 5.32KB gz 1.40KB separate.
