Choose the client when two are registered

Set client to 'axios' or 'fetch' when both client plugins are present, so the handlers know which one to call. pluginAxios and pluginFetch both default output.path to clients, so give each its own path here too, otherwise the second one registered overwrites the first's generated files.

kubb.config.ts

import { defineConfig } from 'kubb/config'
import { pluginTs } from '@kubb/plugin-ts'
import { pluginZod } from '@kubb/plugin-zod'
import { pluginAxios } from '@kubb/plugin-axios'
import { pluginFetch } from '@kubb/plugin-fetch'
import { pluginMcp } from '@kubb/plugin-mcp'

export default defineConfig({
  input: './petStore.yaml',
  output: { path: './src/gen', clean: true },
  plugins: [
    pluginTs(),
    pluginZod(),
    pluginAxios({ output: { path: './clients-axios' }, baseURL: 'https://petstore.swagger.io/v2' }),
    pluginFetch({ output: { path: './clients-fetch' }, baseURL: 'https://petstore.swagger.io/v2' }),
    pluginMcp({ client: 'axios' }),
  ],
})

Output example

src/gen/mcp/getPetById.ts

import type { GetPetByIdOptions } from '../types/GetPetById'
import type { RequestHandlerExtra } from '@modelcontextprotocol/sdk/shared/protocol'
import type { CallToolResult, ServerNotification, ServerRequest } from '@modelcontextprotocol/sdk/types'
import { getPetById } from '../clients-axios/getPetById'

export async function getPetByIdHandler({ path }: GetPetByIdOptions, request: RequestHandlerExtra<ServerRequest, ServerNotification>): Promise<Promise<CallToolResult>> {
  const res = await getPetById({ path })

  return {
    content: [{ type: 'text', text: JSON.stringify(res.data) }],
    structuredContent: { data: res.data },
  }
}

Even with pluginFetch also registered, the handler imports from clients-axios, the path given to pluginAxios, because client: 'axios' picked it.

usage.ts

import { startServer } from './src/gen/mcp/server'

await startServer()
