cellflow 0.6.0

Cell+Flow protocol as a pure Python library — persistent memory, earned trust (IF/Karma), discovery, and Agent collaboration. Zero MCP dependency; cellflow-mcp is the MCP skin on top.

cellflow

Cell+Flow protocol as a pure Python library. Zero MCP dependency — no server to start, no MCP host required. cellflow-mcp is the MCP transport skin on top of this library (SPEC §10: transport-agnostic — protocol capability = library; MCP is just one skin).

pip install cellflow

from cellflow import CellFlow

cf = CellFlow(storage_path="./my_data")           # local SQLite, no server
cell = cf.cell_register(schema_type="agent.v1", genome={"name": "my agent"})
cf.flow_capture(topic="test", content="hello")
print(cf.calculate_if(cell["cell_id"]))           # IF: earned trust, 0-100

Layout (mirrors the protocol)

Module	What lives there
cellflow.core	cell_register / cell_get / export / import / lifecycle
cellflow.flow	flow_capture / flow_recall / flow_list / flow_delete
cellflow.history	hash-chain verify_history
cellflow.trust	calculate_if / karma (three hard gates + four weights)
cellflow.discover	discover_agents (exploration quota) / dht_announce
cellflow.divide	divide_create / divide_parallel / backflow_experience
cellflow.comms	send_flow / pull_inbox (endpoint-direct + DHT relay)
cellflow.identity	Ed25519 identity_create / identity_verify
cellflow.task_market	publish_task / accept_task / deliver_task
cellflow.audit .penalty .witness	anti-cheat machinery
cellflow.shadow	shadow Cells (passive infection + claim)
cellflow.email_bridge .protocol_bridge	email / A2A / MCP / HTTP → Flow
cellflow.storage	SQLite backend (injectable — see below)

Deeper internals stay importable at cellflow.modules.* (e.g. cellflow.modules.karma) — same modules, one physical copy.

Injectable storage (P2)

Default is local SQLite. Pass any object implementing the Storage duck-type (read / write / append / delete / search / upsert):

cf = CellFlow(storage=MyCustomStorage())

Or migrate existing SPEC-shaped data losslessly:

cf.cell_import({"cells": [...], "flows": [...]})   # SPEC §1/§2 field layout

Relationship to cellflow-mcp

cellflow-mcp depends on this package and only adds the 56 @mcp.tool() pass-throughs, the CLI, and the HTTP facade. All protocol behaviour — IF/Karma math, hash chains, discovery ranking, bridges — lives here and is identical through every transport.
