How do I get an Anthropic API Key?

Log in to the [**Anthropic Console**](https://console.anthropic.com), go to **Account Settings > API Keys** and click **Create Key**. Copy the key immediately — it starts with `sk-ant-` and won't be shown again. You can also create workspace-scoped keys to control spending by use case.

What models are available?

Use the `list_models` tool to see all available Claude models. Current models include Claude Sonnet 4, Claude Opus 4 and Claude Haiku variants, each with different capabilities, context windows and pricing. The model ID format is like `claude-sonnet-4-20250514`.

Can I send multi-turn conversations?

Yes! Pass a messages array with alternating 'user' and 'assistant' roles. Each message has a 'role' and 'content' field. Claude will continue the conversation based on the full message history. Example: [{"role":"user","content":"Hello"},{"role":"assistant","content":"Hi!"},{"role":"user","content":"What's 2+2?"}].

How does batch processing work?

Use `create_batch_message` with an array of independent message requests. Each request is processed asynchronously and costs 50% less than individual requests. Use `get_batch_message` to check progress and results. Batches are ideal when you have many unrelated prompts to process.

Anthropic Alternative MCP Tools for Google ADK (6)

These 6 tools become available when you connect Anthropic Alternative to Google ADK via MCP:

cancel_batch_message

Requests that have already been completed cannot be cancelled. Provide the batch ID. This is useful if you submitted a large batch by mistake and want to stop further processing to save costs. Cancel an in-progress batch message request

count_tokens

Requires the model ID and messages array. Returns the total input token count. Useful for estimating API costs and ensuring messages fit within context limits. Count tokens in a message before sending to Claude

create_batch_message

Each request in the batch has its own model, messages, max_tokens, etc. This is more cost-effective than individual requests when you have many independent prompts to process. Returns a batch ID for tracking. Use get_batch_message to check progress. Create a batch of message requests to Claude

get_batch_message

Returns the batch status (in_progress, succeeded, expired, canceling, canceled, failed), request counts (total, succeeded, errored) and individual results. Use the batch ID returned from create_batch_message. Get the status of a batch message request

list_models

Each model returns its ID (e.g. "claude-sonnet-4-20250514"), display name, creation date and capabilities. Use this to discover which models are available and their IDs for use with the send_message tool. List all available Anthropic Claude models

send_message

Requires the model ID (e.g. "claude-sonnet-4-20250514") and messages array in JSON format. Each message must have a "role" ("user" or "assistant") and "content" (text or array of content blocks). Optionally set max_tokens (default 1024), system prompt and temperature (0-1). Returns the assistant's response text. Send a message to Claude (Messages API)

Example Prompts for Anthropic Alternative in Google ADK

Ready-to-use prompts you can give your Google ADK agent to start working with Anthropic Alternative immediately.

"Send a message to Claude asking 'What is the capital of Brazil?'"

"List all available Claude models."

"Count tokens for a message asking Claude to summarize a 500-word article."

Anthropic Alternative + Google ADK FAQ

Common questions about integrating Anthropic Alternative MCP Server with Google ADK.

How does Google ADK connect to MCP servers?

Import the MCP toolset class and pass the server URL. ADK discovers and registers all tools automatically, making them available to your agent's tool-use loop.

Can ADK agents use multiple MCP servers?

Yes. Declare multiple MCP tool providers in your agent configuration. ADK merges all tool schemas and the agent can call tools from any server in a single turn.

Which Gemini models work best with MCP tools?

Gemini 2.0 Flash and Pro models both support function calling required for MCP tools. Flash is recommended for latency-sensitive use cases, Pro for complex reasoning.
