Everything an agent needs to remember.

A memory stack you plug in once and rely on — search, integrity, compaction, and provenance, all behind one MCP server.

SEARCH · 0.001 ms

Exact Hash Search

Deterministic lookup by SHA-256 hash — O(1), no embeddings, no collisions. Ideal for dedup and 'did the agent already see this?' checks.

INTEGRITY · TRUTH GATE

Truth Gate & Memory Write Guard

Every fact is cross-checked against known data before it's stored. Blocks prompt injection and memory poisoning — an agent's memory stays trustworthy.

CONTEXT · COMPACTION

Context Engine

Dense session compression into a reusable prefix. Up to −87% tokens on long sessions, so context never burns out.

PROVENANCE

Provenance Guard

System prompts and role text never leak into facts. Every memory has an auditable source.

DURABILITY

Op Journal

Append-only log with write-acknowledgement. No silent data loss — every ADD/UPDATE is confirmed.

5-minute integration

Connect an agent, get memory.

ShineMnemos is an MCP server. Point your agent at it, and it gains persistent, queryable memory — paid as you go via x402, USDC on Base.

agent@host:~$ connect mnemos
# point your agent at the MCP server
$ mcp add mnemos --url http://167.104.100.27:8081
# remember something — passes through the truth gate
$ mnemos write --gate truth --payload "..."
✓ 5/5 gates passed · stored
# retrieve with exact lookup
$ mnemos search --exact "..."
> hit in 0.001 ms · 100% accuracy
