🛡️ Product Family

Perseus is the live context engine. Seven specialized products extend it:

Mimir — Persistent Memory (MCP)

Mimir is the persistent memory backend for Perseus — a lightweight Rust MCP server with SQLite + FTS5. Zero network calls, no API keys. As of v2.7.0, offline dense/hybrid embeddings are bundled by default (the model is compiled into the binary), so semantic recall works zero-config with no external model download. v2.12.0 provides 48 MCP tools across structured entities, hybrid vector search, RAG, connectors, confidence decay, journal events, and state management: mimir_remember, mimir_recall, mimir_context, mimir_traverse, mimir_decay, mimir_stats, mimir_health, and more.

curl -sSL https://raw.githubusercontent.com/Perseus-Computing-LLC/mimir/main/scripts/bootstrap.sh | bash

Hermes Agent — add to ~/.hermes/config.yaml:

mcp_servers:
  mimir:
    command: "mimir"
    args: ["--db", "~/.mimir/data/mimir.db"]

Claude Desktop / Cursor — add to your MCP settings:

{
  "mcpServers": {
    "mimir": {
      "command": "mimir",
      "args": ["--db", "/home/YOU/.mimir/data/mimir.db"]
    }
  }
}

Perseus integration — add to .perseus/config.yaml:

mimir:
  enabled: true
  command: ["mimir", "serve", "--db", "~/.mimir/data/mimir.db"]

Then add @memory mode=search query="your terms" to .perseus/context.md and Perseus resolves live recall at render time.

Works with any MCP-compatible assistant.
