letta-ceki

Letta toolkit for Ceki — drive a real Chrome session from your Letta agent.

Killer combo. Letta's archival memory + Ceki's profile export = browser sessions that remember themselves across agent restarts. Log in once on Monday, your agent walks straight into the dashboard on Friday — no cookies stored in your code, no second login.

Install

pip install letta-ceki

The squat alias ceki-letta is reserved by the same project and depends on letta-ceki — both resolve to the same symbols.

Architecture

Variant C — structural toolkit. Eleven self-contained Python functions that the Letta agent's own LLM plans across:

Tool	What it does
ceki_rent_browser	Rent a real Chrome session and return its session_id.
ceki_navigate	Open a URL.
ceki_click	Click at viewport coordinates. Mouse jitter ON by default.
ceki_type	Type into the focused element. Cadence + jitter ON by default.
ceki_scroll	Scroll by delta_y pixels.
ceki_screenshot	PNG of the current viewport as base64.
ceki_snapshot	Screenshot + drained chat messages from the provider.
ceki_chat_send	Send a chat message to the human provider (captcha / OTP).
ceki_stop	End the session — always call this when done.
ceki_export_profile	Killer: export cookies/storage/fingerprint to Letta memory.
ceki_restore_profile	Killer: restore a saved profile into a fresh rent.

There is no server-side NL endpoint and no LLM lives inside this package — your Letta agent's own model does the planning.

Register the tools in your Letta workspace

import os
os.environ["CEKI_API_KEY"] = "your_ceki_key"     # https://ceki.me dashboard
os.environ["LETTA_TOKEN"] = "your_letta_token"   # https://app.letta.com/settings/api-keys

from letta_ceki import register_all
tool_ids = register_all()
print(f"Registered {len(tool_ids)} tools.")

Then attach the tools to your agent in the Letta UI, or programmatically:

from letta_client import Letta
client = Letta(token=os.environ["LETTA_TOKEN"])
client.agents.update(agent_id="your_agent_id", tool_ids=list(tool_ids.values()))

The killer combo — persistent sessions

Tell your agent in its persona prompt:

After a successful login, always call ceki_export_profile.
On a fresh rent for a previously-logged-in site, always call
ceki_restore_profile before navigating.

That is the entire setup. Now every login the agent performs is durable:

# Run A — agent logs into your.example.com, then:
ceki_export_profile(session_id, profile_name="your-example")

# Letta restarts. Memory survives.

# Run B — fresh rent on a new browser:
ceki_restore_profile(session_id, profile_name="your-example")
# → cookies, localStorage, sessionStorage, fingerprint all restored
ceki_navigate(session_id, "https://your.example.com/dashboard")
# → already authenticated

See examples/persistent_session.py for an end-to-end runnable demo.
