@stithy/memory

Stop re-explaining context to your AI. Stithy Memory remembers everything across sessions, every tool, every project.

A polished cross-session memory MCP server for Claude, Cursor, Windsurf, and Claude Code. 100% local — your data never leaves your machine.

$6.99/month via the MCP Marketplace. 30-day refund, no questions asked.

What you get

• Semantic search that finds the right memory, not just keyword matches
• Auto-dedup — store the same fact twice, it merges instead of cluttering
• Auto-decay — old, low-importance memories prune themselves so search stays sharp
• Soft-delete with trash — accidental deletes are recoverable
• Bulk import/export — your data, always portable
• Auto-categorize — your AI suggests tags for untagged memories
• Consolidate — surfaces related memories you can merge
• One-command install across Claude Desktop, Cursor, Windsurf, Claude Code
• 100% local — embeddings + storage on your device, no telemetry, no servers
• Actively maintained — bug fixes within 7 days

Install (30 seconds)

npx -y @stithy/memory install

This detects every MCP-compatible AI client on your machine and writes the config. Restart the client and you're done.

License key

After purchasing on the marketplace you'll get a license key starting with mcp_live_.... Set it as MCP_LICENSE_KEY in your environment, or paste it into your MCP client's env vars block. Without a valid key the server refuses to start.

export MCP_LICENSE_KEY="mcp_live_..."

Or in your client config:

{
  "mcpServers": {
    "stithy-memory": {
      "command": "npx",
      "args": ["-y", "@stithy/memory"],
      "env": { "MCP_LICENSE_KEY": "mcp_live_..." }
    }
  }
}

The installer wires this up automatically when you provide your key.

Use

In any chat with your AI:

"Remember that I prefer pnpm over npm for all my projects." "Remember the Postgres prod URL is in 1Password under 'prod-db', not in .env." "What did I tell you about the auth refactor last week?"

The AI will call store_memory and search_memory automatically.

Tools

| Tool | What it does | |---|---| | store_memory | Save a fact, decision, or context. Auto-dedupes. | | search_memory | Semantic search across all memories. | | list_memories | Browse chronologically, optionally by tag. | | get_memory | Retrieve a single memory by id. | | update_memory | Edit an existing memory. | | delete_memory | Move a memory to trash (recoverable). | | restore_memory | Restore from trash. | | list_trash | Show recoverable deletions. | | purge_trash | Permanently delete old trash. | | list_tags | All tags with usage counts. | | decay_memories | Prune old, low-importance memories (dry-run by default). | | memory_stats | Total count + storage size + tag count. | | bulk_import | Import from JSON array. | | bulk_export | Export everything to JSON. | | auto_categorize | Have your AI tag untagged memories. | | consolidate_memories | Find clusters to merge. |

Configuration

| Env var | Default | What | |---|---|---| | MCP_LICENSE_KEY | — | Required. Marketplace license key. | | STITHY_MEMORY_DB | ~/.stithy/memory.db | SQLite database path |

How it works

• SQLite with sqlite-vec for vector storage and FTS5 for keyword fallback
• Embeddings: Xenova/all-MiniLM-L6-v2 (384 dimensions, runs locally via @xenova/transformers)
• Dedup: cosine similarity > 0.95 triggers merge instead of insert
• Decay: configurable TTL filtered by importance and tags, with dry-run safety
• Soft-delete: deletes go to a trash table for 30+ days
