Description
Massive is a platform that delivers high-quality U.S. market data, ideal for AI agents and applications powered by large language models (LLMs). The platform offers several integration methods, including the MCP server, direct REST API integration, and the use of Skills to enhance AI performance. The MCP server is a hosted solution that allows AI agents to access market data efficiently, using OAuth for authentication and offering a streamlined setup process. It supports up to 10 concurrent workspaces and provides 64 MB of working storage per session, making it suitable for typical agentic analysis.
For users who require more control or need to work with large local datasets, Massive offers a self-hosted MCP server option. This version includes a local data workspace capable of storing results as in-memory DataFrames, running SQL queries, and applying financial functions. Developers can also connect AI systems directly to Massive's REST API, using function calling and tool use in frameworks like OpenAI and Anthropic. Massive provides official client libraries in Python, JavaScript, Go, and Kotlin, which handle authentication, retries, pagination, and more, ensuring a robust foundation for production code.
Massive's documentation is designed to be AI-friendly, available in structured Markdown format, and includes llms.txt and llms-full.txt files for flexible documentation access. These resources help AI agents discover and use data intelligently, with options for high-level overviews or detailed endpoint descriptions. The platform also supports the use of Skills, which encode internal conventions and best practices to improve AI output consistency and accuracy.
Overall, Massive is a versatile tool for developers and analysts looking to integrate high-quality market data into their AI workflows, offering a range of options to suit different needs and levels of control.
