Showcase: Mimir — local-first persistent memory server (43 MCP tools, AES-256, bi-temporal)

[tcconnally]

Hi,

Wanted to surface Mimir for the ext-apps ecosystem showcase / registry.

Mimir is a local-first persistent memory server for AI agents, distributed as a static binary with 43 MCP tools:

• Cross-session entity storage with structured categories, types, and relationships
• AES-256-GCM encryption at rest
• Ebbinghaus decay scoring — memories fade over time like human memory, and get reinforced on recall
• FTS5 + dense vector hybrid recall
• Bi-temporal entity history (time-travel to past beliefs)
• Vault export to Obsidian-compatible markdown
• Knowledge graph traversal via entity links
• Zero cloud dependencies — single binary, local SQLite

Works with Claude Desktop, Claude Code, Cursor, and any MCP-compatible client.

• Repo: https://github.com/Perseus-Computing-LLC/mimir
• License: MIT
• Install: single binary download or cargo install mimir-mcp

Happy to add whatever documentation format the registry requires. Let me know what's needed.
