What is Fulcra?

Fulcra is a user-owned context backend for AI agents. Under the hood it is a data platform: what accumulates for each owner is a context lake mixing structured, semi-structured, and unstructured data from many sources, agents, and applications over time. Agents read from and write to this single context you control, so they can pick up where the last one left off instead of starting over as strangers.

How to use Fulcra?

Start for free with 5 GB of storage — no separate signup, your account is created the first time you connect. Point any MCP client at the Fulcra Personal MCP server URL (https://mcp.fulcradynamics.com) and sign in, or build with the OAuth2-protected Life API, Fulcra CLI, or Python SDK. Connect your apps, devices, and tools to bring data into your context lake, then let your agents read what changed, do the work, and write results back.
