fulcra-api: the Fulcra Python library and CLI
Fulcra is a durable, user-owned context store for people and their AI agents. A user's data lives in one place they control, so any of their agents, in any harness or session, can read and write it, share it with other people's agents, and pick up where another left off.
This package provides:
fulcra, a command-line tool for people and agents with a shell. It prints JSON for piping into tools likejq, and logs in with a browser-based device flow, so it never handles a password.fulcra_api, a Python library for scripts, agents that write code, and notebooks.
Both talk to the same Fulcra account and need Python 3.11 or newer.
Quick start (CLI)
Run it without installing using uv:
uvx fulcra-api auth login # opens a browser to log in; the login is cached
uvx fulcra-api user-info
Or install it with pip install fulcra-api and run fulcra.
A typical session:
# What's new since you last looked, for you and everyone who shares with you?
fulcra data-updates "1 hour" --include-shared
# Create your own data type, record into it, and read it back
fulcra data-type create Event "Decision" -d "Decisions made in project meetings" \
--fields '{"properties": {"summary": {"type": "string"}}, "required": ["summary"]}'
fulcra record Event/<UUID> --summary="Ship the beta on Friday"
fulcra get-records Event/<UUID> "1 week"
# Keep files (notes, memory, exports) with full version history
fulcra file upload notes.md /projects/beta/notes.md
fulcra file download /projects/beta/notes.md -
# Share exactly one data type with another Fulcra user
fulcra share create --name "Project decisions" --data-type Event/<UUID> --user-id <USER-UUID>
The commands fall into four groups:
- Data types and records:
catalog,data-type,record,get-records,delete,data-updates,metric-time-series. - Files:
file. - Sharing:
share,group,tag. - Device data: synced by the optional Context by Fulcra iOS app.
calendars,calendar-events,location-at-time,location-time-series,sleep-cycles,sleep-stages,apple-workouts, and others.
fulcra --help and fulcra <command> --help document every command and option. For agents that can't log in non-interactively, fulcra auth login --get-auth-url prints a link for the user, and fulcra auth login --device-code <CODE> finishes the login.
Quick start (Python)
from fulcra_api.core import FulcraAPI
fulcra = FulcraAPI()
fulcra.authorize() # prints a login link and waits for the user to approve it
updates = fulcra.data_updates("2026-10-01T00:00:00Z", "2026-10-02T00:00:00Z", include_shared=True)
The documentation site has the full API reference.
For AI agents
AGENTS.md explains what agents use Fulcra for and how to use this package. The agent-skills library has ready-made skills, such as coordinating a user's agents, connecting with other people's agents, tracking, and memory. Agents without a shell can use the Fulcra MCP server instead.
Platform documentation is at docs.fulcradynamics.com, including the CLI guide and the REST API reference.
