Anthropic for your agents.

What agents can do with Anthropic

Curated for agents: the calls that matter, with schemas and descriptions written for tool use, not an endpoint dump.

• anthropic_list_models

  List available Claude models.

• anthropic_message

  One-shot message to Claude. `messages` is [{role, content}]; max_tokens is required by the API.

• anthropic_get_model

  For an AI agent: fetch metadata for one model by id (display name, creation date). `model_id` is a value from list_models, e.g. claude-sonnet-4-20250514.

• anthropic_count_tokens

  For an AI agent: count the input tokens a Messages request would use, without running it. Same `model`/`messages` shape as message; returns input_tokens so you can budget before calling.

• anthropic_create_message_batch

  For an AI agent: submit many Messages requests for cheaper async processing. `requests` is an array of {custom_id, params} where params is a full Messages body. Returns a batch id to poll with get_message_batch.

• anthropic_list_message_batches

  For an AI agent: list Message Batches, most recent first.

• anthropic_get_message_batch

  For an AI agent: poll one Message Batch by id for processing_status and result counts. When it has ended, download results from the results_url in the response.

• anthropic_cancel_message_batch

  Cancel a Message Batch that has not yet completed. Ended batches cannot be canceled.
