Open-source client SDKs (Python, TypeScript, Go), CLI, API docs, and prebuilt binaries for the Mneme agent cognition runtime (memory, context, ontology, knowledge). Apache-2.0.
Open (Apache-2.0) client SDKs, examples, API reference, and prebuilt binaries for Mneme.
Mneme is a cognition runtime that gives software agents long-term memory, context assembly, and knowledge representation. Think of it as a memory subsystem that sits alongside your LLM: every observation, fact, decision, and plan is stored as a typed, temporal, branchable record, and you retrieve it with a hybrid search (lexical + semantic + relation + time) plus context assembly.
Mneme's data model combines Git-like branching with cognitive memory types:
Memory type Example ---------------------- episode raw events (user said X, server returned Y) fact asserted truths (subject-predicate-object, with validity windows) knowledge structured belief (entity relationships, classifications) experience reflection after an action ("what went well / poorly") simulation hypothetical scenarios run to reason about outcomes emotion, intention, procedure, belief, mission, preference internal agent state
Every record is immutable and append-only, tagged with branch, timestamp, retention tier, and identity scope (tenant/project). The engine owns the semantics; storage backends are replaceable.
Mneme-open is the public, open-source window into Mneme. It contains everything you need to integrate with a running Mneme server — client libraries, CLI tools, protocol schemas, and API documentation —?under the Apache-2.0 license. The Mneme engine source is not included here; this repository ships only the client-facing layer.
