Crate memory_mcp 

Semantic memory engine with pure-Rust embeddings and git-backed storage.

This crate provides the library core for memory-mcp, an MCP server that stores and retrieves memories using vector similarity search. Embeddings are computed on-device via candle (BERT inference) with no C/C++ FFI.

Modules

auth

Token resolution, OAuth device flow, and credential storage backends.

embedding

Embedding backends for computing vector representations of text.

error

Error types used throughout the crate.

health

HTTP health-check handlers (/readyz). Health reporting infrastructure and HTTP handlers.

index

HNSW vector index for approximate nearest-neighbour search. Vector index module — defines the VectorStore trait and provides concrete implementations backed by usearch (HNSW) and an in-memory HashMap (for tests).

repo

Git-backed memory repository — read, write, sync, and diff operations.

server

MCP server implementation — tool handlers for the memory protocol.

types

Domain types: memories, scopes, metadata, validation, and application state.
