Mnemes
Personal memory server
Self-hosted devices, actors, operation envelopes, provenance edges, routed shard selection, synchronization receipts, revocation, and quarantine.
03THE PLATFORM
Three layers.
One contract vocabulary.
You can stop at the layer you need. semantic-memory owns memory quality. semantic-memory-mcp exposes it to one local agent. Mnemes adds the self-hosted server, multi-device identity, routing, and synchronization metadata.
semantic-memory-mcp
Protocol server
Stdio and loopback HTTP, runtime-discovered tools, bounded profiles, witnessed search, replay, graph traversal, authority decisions, and maintenance boundaries.
semantic-memory
Memory engine
SQLite authority, hybrid retrieval, embeddings, graph, bitemporal state, provenance, receipts, replay privacy, integrity, and reconciliation.
01 / THE ENGINE
More than vector search.
Less than an oracle.
The memory engine owns durable storage and retrieval mechanics. It does not own claim truth, action permission, MCP transport policy, or automatic activation of every research feature.
Canonical store
SQLite content, raw f32 embeddings, temporal fields, lineage, authority records, and durable receipts.
Hybrid retrieval
FTS5/BM25 plus dense candidates, weighted reciprocal-rank fusion, deduplication, diversity, and explicit state visibility.
Temporal truth
Current, historical, and superseded fact views with valid time separated from recorded time.
Knowledge graph
Semantic, temporal, causal, and entity relationships with invalidation instead of silent deletion.
Governed operations
Capability-gated append, supersession, redaction, forgetting, export, replay, and origin revocation.
Recovery
Integrity checks and reconciliation rebuild derived state from canonical SQLite authority.

02 / THE PROTOCOL
Tools are capabilities.
Profiles are boundaries.
The running server's tools/list response remains the source of truth. Build features and runtime profile both affect what a client can actually call.
Witnessed recall, replay, and separate assertion/action authority decisions. Designed for the narrowest autonomous surface.
Search, fact reads, graph paths, conversations, namespaces, receipts, and stats without device administration.
Mutation, imports, lifecycle, maintenance, administration, and experimental tools. Treat discovery as runtime evidence, not README promise.

03 / NINE AGENT HOSTS
Use the agent you have.
Keep the memory you built.
Agent Memory Kits are a complete single-device starting point, not a reduced demo. They distribute semantic-memory-mcp into hook-tier and context-tier hosts; Mnemes is added only when a server and cross-device memory boundary are wanted.
Claude Code
Recall, primer, capture, and compaction lifecycle hooks.
Codex
MCP configuration, Python hooks, prompts, and memory skills.
Hermes
Hooks, commands, and skills around one canonical store.
Cursor
MCP plus project-local memory context rules.
Windsurf
MCP and deterministic context-injection guidance.
Cline
MCP plus project or user-scoped rules.
Roo Code
MCP tools with host-native instruction files.
Continue
MCP registration and shared context commands.
OpenCode
MCP registration and local memory rules.
04 / COMPRESSION WITH AN ESCAPE HATCH
Approximate to find.
Exact to decide.
Canonical memory stays exact. Compressed tiers make candidate retrieval smaller and more efficient. Approximate scores find candidates; authoritative f32 scoring decides the final order.
SQLite + raw f32
Durable content and exact vectors remain the authority.
TurboQuant / compressed pools
Derived artifacts narrow the working set under explicit policy.
Exact f32 rerank
Final ranking returns to authoritative vectors before visibility filters.
