The Problem

Every AI tool has its own isolated memory. Tell Claude Code you prefer Python — switch to Cursor, it has no idea. Open Codex — starts from scratch. You repeat yourself endlessly: "we use Postgres", "deploy to Fly.io", "the API is at /v2".

CLAUDE.md and .cursorrules files are manual, fragile, and don't share context across tools.

The Fix

Smara gives your AI tools a shared memory that works everywhere:

You code normally in any tool
       ↓
Smara silently captures decisions, preferences, architecture choices
       ↓
Next session — in any tool — your AI already knows

Install in 30 seconds

npx @smara/mcp-server --init

Or add to your MCP config manually:

{
  "mcpServers": {
    "smara": {
      "command": "npx",
      "args": ["-y", "@smara/mcp-server"],
      "env": {
        "SMARA_API_KEY": "your-key-here"
      }
    }
  }
}

Works with Claude Code (~/.claude/mcp_config.json), Cursor (.cursor/mcp.json), Windsurf (~/.codeium/windsurf/mcp_config.json), and any MCP-compatible client.

How It Works

Ebbinghaus Decay

Memory relevance is scored using Ebbinghaus forgetting curves:

R = e^(-t/S)

Where t is time elapsed and S is memory strength (based on importance + access frequency). Important, frequently-used facts stay strong. Old noise fades naturally. No manual cleanup needed.

Contradiction Detection

Store "we use Postgres" today, then "we migrated to MySQL" next month — Smara detects the contradiction, soft-deletes the old fact, and keeps the new one. Your AI never gets confused by stale context.

Cross-Tool Context

A decision captured in Claude Code is instantly available in Cursor, Windsurf, Codex, or any connected tool. Every memory is tagged with its source — filter by tool or see everything.

---

REST API

Three endpoints. That's it.

Store a memory

curl -X POST https://api.smara.io/v1/memories \
  -H "Authorization: Bearer $SMARA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "user_id": "user_42",
    "fact": "Prefers Python over TypeScript for backend work",
    "importance": 0.8,
    "source": "claude-code"
  }'

Returns "action": "stored", "duplicate" (cosine >= 0.985), or "replaced" (contradiction detected).

Search memories

curl "https://api.smara.io/v1/memories/search?user_id=user_42&q=language+preferences" \
  -H "Authorization: Bearer $SMARA_API_KEY"

Results ranked by semantic similarity × Ebbinghaus decay. Recent + relevant beats old + relevant.

Get context

curl "https://api.smara.io/v1/users/user_42/context?q=preferences" \
  -H "Authorization: Bearer $SMARA_API_KEY"

Returns pre-formatted context ready to inject into LLM system prompts.
