mentedb 0.8.0

The mind database for AI agents

MenteDB Python SDK

Python bindings for MenteDB, the mind database for AI agents. Built with PyO3 and maturin for native Rust performance from Python.

Installation

From source (development)

cd sdks/python
pip install maturin
maturin develop

From PyPI (once published)

pip install mentedb

Quick start

from mentedb import MenteDB

with MenteDB("./agent-memory") as db:
    # process_turn — the primary API, one call does everything
    result = db.process_turn(
        user_message="The deployment failed because the config was missing",
        assistant_response="I'll check the config setup.",
        turn_id=0,
    )
    # result.context — relevant memories for your prompt
    # result.facts_extracted — what was learned this turn
    # result.contradiction_count — conflicting beliefs detected

    # Or use low-level APIs directly:

    # Store a memory
    mid = db.store(
        "The deployment failed because the config was missing",
        memory_type=MemoryType.EPISODIC,
        tags=["deployment", "config"],
    )

    # Recall memories with MQL
    result = db.recall("RECALL tag:deployment LIMIT 5")
    print(result.text)

    # Vector similarity search
    hits = db.search(embedding=[0.1] * 384, k=5)
    for hit in hits:
        print(f"{hit.id}: {hit.score:.4f}")

    # Relate memories
    mid2 = db.store("Always validate config before deploy", memory_type=MemoryType.PROCEDURAL)
    db.relate(mid, mid2, edge_type=EdgeType.CAUSED)

    # Forget a memory
    db.forget(mid)

Cognitive features

The SDK also exposes MenteDB cognitive subsystems for real time stream monitoring, conversation trajectory tracking, and pain signal management.

from mentedb._mentedb_python import CognitionStream, TrajectoryTracker, PainRegistry

# Stream monitoring
stream = CognitionStream(buffer_size=500)
stream.feed_token("The")
stream.feed_token(" sky")
alerts = stream.check_alerts([("some-uuid", "the sky is blue")])

# Trajectory tracking
tracker = TrajectoryTracker(max_turns=50)
tracker.record_turn("deployment", "investigating", ["which env?"])
context = tracker.get_resume_context()

# Pain registry
pain = PainRegistry(max_warnings=3)
pain.record_pain("some-uuid", 0.8, ["timeout", "deploy"], "deploy timed out")
warnings = pain.check_triggers(["deploy"])

API reference

MenteDB

Method	Description
process_turn(user_message, assistant_response, turn_id, project_context, agent_id)	Primary API. Process a conversation turn through the full cognitive pipeline
store(content, memory_type, embedding, agent_id, tags)	Store a memory, returns its UUID
recall(query)	Recall memories using MQL
search(embedding, k)	Vector similarity search
relate(source, target, edge_type, weight)	Add a relationship
forget(memory_id)	Remove a memory
close()	Flush and close the database

Types

MemoryType: episodic, semantic, procedural, anti_pattern, reasoning, correction

EdgeType: caused, before, related, contradicts, supports, supersedes, derived, part_of
