openclaw-memgpt-sidecar
A maintained fork of MemGPT that packages the MemGPT memory architecture as a Python sidecar for the openclaw-memgpt plugin.
It preserves MemGPT's memory design — the core / archival / recall memory tiers, the function-calling syscall vocabulary, and the recursive summariser — while modernising the surrounding plumbing so the architecture runs on the current Python LLM ecosystem and against Anthropic/Claude models through OpenAI-compatible proxies.
Relationship to upstream MemGPT
This project is a fork of MemGPT (originally cpacker/MemGPT, now maintained as
letta-ai/letta), described in
Packer et al., 2024. Originally authored by Packer et al.
(2024); maintained as a fork by Altay Acar. All credit for the memory architecture belongs to the
original authors:
- Charles Packer
- Vivian Fang
- Sarah Wooders
- Shishir Patil
- Kevin Lin
- Ion Stoica
- Joseph E. Gonzalez
The fork exists because the original pymemgpt release was written against the 2023 single-vendor
OpenAI ecosystem (the pre-v1 functions API, openai SDK v0.28, llama_index 0.8). Running that
architecture unchanged against today's SDKs and against non-OpenAI providers (e.g. Claude via
LiteLLM) is not possible without compatibility work. This fork supplies exactly that work and
nothing more: the memory architecture is preserved; only the plumbing is modernised.
Scope of modifications
The changes are deliberately narrow and limited to compatibility and dependency plumbing:
- Wire-format modernisation (Anthropic/Claude compatibility) — translation at the SDK boundary from MemGPT's pre-v1 OpenAI functions vocabulary to the modern OpenAI tools API, so payloads reach Claude (and other providers behind OpenAI-compatible proxies) as valid tool-use exchanges.
- Dependency modernisation —
openaiSDK v0.28 → v2.x port,llama_index0.8 → 0.14 migration, and accompanying dependency-pin loosening. - Adapter-layer ports — small, behaviour-preserving ports and reuse-oriented refactors that let the existing code run on the modern dependencies without altering the memory architecture.
A full, file-level account of what changed relative to upstream is in CHANGES.md, per the Apache 2.0 modification-notice requirement.
Use
This package is primarily intended as the sidecar dependency of the openclaw-memgpt plugin. Independent use is possible, but API stability is scoped to the plugin's needs and is not guaranteed for other consumers.
Installation
pip install openclaw-memgpt-sidecar==1.0.0
Python 3.11 is required.
