name: openclaw-memory-pensieve-algorand-v3 description: Long-term episodic memory for OpenClaw with append-only hash-chained local layers, daily dream-cycle consolidation, AES-GCM encrypted Algorand anchoring, and post-anchor recoverability validation. Single MCP server — no scripts, no extra venvs.

OpenClaw Memory Pensieve v3.0.0

MCP server

All functionality is in one file: server.py.

Register it in Claude Code settings:

{
  "mcpServers": {
    "pensieve": {
      "command": "python3",
      "args": ["/path/to/server.py"],
      "env": {
        "OPENCLAW_WORKSPACE": "/path/to/workspace",
        "ALGORAND_WALLET_ADDRESS": "<address>",
        "ALGORAND_WALLET_MNEMONIC": "<25-word mnemonic>",
        "ALGORAND_NOTE_KEY_HEX": "<64 hex chars = 32 bytes>",
        "ALGORAND_ALGOD_URL": "https://mainnet-api.algonode.cloud",
        "ALGORAND_INDEXER_URL": "https://mainnet-idx.algonode.cloud"
      }
    }
  }
}

Install dependencies (one-time):

pip install mcp algosdk cryptography

Tools

Daily workflow

1. Capture events throughout the day with pensieve_capture.
2. At end-of-day, run pensieve_dream_cycle to consolidate patterns.
3. Run pensieve_anchor to encrypt and commit to Algorand.
4. Run pensieve_validate — only trust recovery claims when ok=true.

Mandatory operational rules

• All *.jsonl files are append-only. Never rewrite or delete lines.
• Secrets stay in env vars (or .secrets/). Never print them in chat.
• Anchor encrypted payloads only — never plaintext memory.
• Treat pensieve_validate failures as blocking for disaster-recovery claims.

Security

Sensitive values are read from environment variables at runtime:

• ALGORAND_WALLET_MNEMONIC — never logged, never written to disk by the server.
• ALGORAND_NOTE_KEY_HEX — 64 hex chars (32-byte AES key).

Fallback to .secrets/algorand-wallet-nox.json and .secrets/algorand-note-key.bin is supported for local development only. Prefer env vars in all deployments.

Use a dedicated low-balance anchoring wallet. Fund it with enough ALGO for your expected daily TX volume (see cost model in server.py module docstring). Never reuse the main OpenClaw operations wallet for anchoring.

Recovery

# Recover and inspect
pensieve_recover(date="2026-03-14")

# Recover and write files to memory/recovered/
pensieve_recover(date="2026-03-14", restore=True)
