Drop-in /memories backend with governance for the Anthropic memory_20250818 tool

MOOTx01 Memory Adapter

Drop-in /memories backend with governance for the Anthropic memory_20250818 tool.

What it does

Any Claude 4+ / Fable 5 agent that thinks it is reading and writing /memories files is actually reading and writing governed MOOTx01 drawers — with dedup, provenance, sensitivity floor, confirmation state, and a full audit trail included.

The differentiator

Every model-written memory lands as unconfirmed with derived trust. A startup scan or audit pass can quarantine suspect lessons using the estate's contained filter and anomaly lenses. This is the poisoning defense the ecosystem currently lacks — the memory tool contract gives models write access; MOOTx01 gives you the governance to trust (or not trust) what they wrote.

Two surfaces

1. MCP tool (built into mootx01)

The mootx01 daemon registers a memory tool on its MCP surface that matches Anthropic's contract exactly. Claude Code and Claude Desktop users already connected to mootx01 as an MCP server get the memory tool for free — no adapter needed.

2. Python SDK handler (this package)

For Messages API users who run the tool-use loop themselves:

from moot_memory import MootMemoryTool
import anthropic

client = anthropic.Anthropic()
memory = MootMemoryTool(base_url="http://127.0.0.1:4242")

runner = client.beta.messages.tool_runner(
    model="claude-opus-4-8",
    max_tokens=1024,
    messages=[{"role": "user", "content": "Remember that Acme prefers email."}],
    tools=[memory],
)
final = runner.until_done()

Or standalone without the SDK:

from moot_memory import MootMemoryHandler

handler = MootMemoryHandler(base_url="http://127.0.0.1:4242")
result = handler.execute({"command": "view", "path": "/memories"})

Op mapping

memory_20250818	Estate behavior
view (dir)	enumerate drawers in wing="memories"
view (file)	drawer content with line numbers
create	capture as unconfirmed drawer
str_replace	supersede: new content, old withdrawn (full lineage)
insert	supersede: content with insertion applied
delete	soft withdrawal (never hard-erase from model ops)
rename	capture at new location, withdraw old

Security

• Path traversal protection: all paths validated against /memories
• Model writes land unconfirmed: poisoning quarantine seam
• Deletes are soft withdrawals: reversible, audit trail preserved
• Sensitivity floor: adapter wing is Normal
• File size cap: 100KB per file
• No hidden files: dotfiles rejected

Tests

# Against the running daemon
python -m pytest apps/moot-memory-adapter/tests/

# The poisoning quarantine test
python -m pytest apps/moot-memory-adapter/tests/test_memory_adapter.py::TestPoisoningQuarantine -v

Requirements

• Running mootx01 daemon (v1.0.22+)
• Python 3.10+
• anthropic SDK (optional, for the BetaAbstractMemoryTool subclass)
