@moxxy/plugin-provider-anthropic

The Anthropic (Claude) LLMProvider for moxxy — streams the Messages API with tool use and adaptive extended thinking, and translates moxxy's ProviderRequest/event shape ↔ the Anthropic wire format. Register it into a Session to route turns to Claude.

Install

npm i @moxxy/core @moxxy/sdk @moxxy/mode-default @moxxy/plugin-provider-anthropic

Usage

import { Session, runTurn, autoAllowResolver } from '@moxxy/core';
import defaultModePlugin from '@moxxy/mode-default';
import anthropicPlugin from '@moxxy/plugin-provider-anthropic';

const session = new Session({ cwd: process.cwd(), permissionResolver: autoAllowResolver });
session.pluginHost.registerStatic(defaultModePlugin);
session.pluginHost.registerStatic(anthropicPlugin);

session.providers.setActive('anthropic', {
  apiKey: process.env.ANTHROPIC_API_KEY,
  // model: 'claude-opus-4-8',   // optional — defaults to the built-in catalog
});

for await (const e of runTurn(session, 'Write a haiku about TypeScript.')) {
  if (e.type === 'assistant_chunk') process.stdout.write(e.delta);
}

Config

field	meaning
`apiKey`	your Anthropic API key (or wire it through the Session's `secretResolver`)
`model` / `models`	pick / override the advertised model catalog

Mix it with @moxxy/plugin-provider-openai: register both and setActive('anthropic' | 'openai', …) to switch vendors per turn.

Exports

default / anthropicPlugin (register this), anthropicProviderDef, AnthropicProvider, anthropicModels, validateKey.
