What is the Anthropic MCP Server?
The Anthropic MCP Server enables seamless integration with Claude, the leading AI model for complex reasoning and creative tasks. This server allows your AI agent to interact with other Claude models, manage asynchronous batch processing, and optimize costs through direct API access.
What you can do
- Direct Messaging — Send multi-turn messages and system prompts to any Claude model (Haiku, Sonnet, Opus).
- Asynchronous Batching — Create and manage high-volume message batches with 50% cost savings using the Message Batch API.
- Cost Estimation — Built-in tools to calculate the expected cost of your prompts based on token counts and current pricing.
- Rate Limit Monitoring — Keep track of your account's Requests Per Minute (RPM) and Tokens Per Minute (TPM) limits directly from your chat.
- Model Discovery — List all available models and check their specific technical capabilities.
How it works
- Subscribe to this server
- Provide your Anthropic API Key
- Start querying Claude models or managing your API usage through natural language.
Who is this for?
- Developers — Quickly test prompt variations and monitor API limits without leaving your workspace.
- AI Researchers — Run large-scale evaluations using the Batch API for significant cost reduction.
- Project Managers — Track AI spending and model availability across your team's account.

Frequently asked questions
What is the benefit of the Batch API?
The Message Batch API allows you to send large numbers of requests to be processed asynchronously within 24 hours. The main benefits are a 50% discount on token pricing and higher rate limits compared to standard requests.
Can I use this server to switch between Claude 3.5 Sonnet and Opus?
Yes! You can specify the model ID in the create_message tool. This allows your agent to leverage different models depending on the complexity of the task.
How do I monitor my rate limits?
Use the check_rate_limits tool. It queries Anthropic's API and extracts the current remaining tokens and requests from the response headers, helping you avoid 429 errors.
How does LlamaIndex connect to MCP servers?
Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
Can I combine MCP tools with vector stores?
Yes. LlamaIndex agents can query Anthropic tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
Does LlamaIndex support async MCP calls?
Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
