Openclaw Fcma

What is Openclaw Fcma?

Openclaw Fcma is a persistent memory layer for AI assistants, giving them structured recall across conversations. It uses a six-tier hierarchical architecture (scratchpad, journal, knowledge graph, document library, world state, and ledger) to store episodic memories, relationships, documents, live facts, and session summaries. Designed for developers and power users of Claude Desktop via the Model Context Protocol (MCP), it replaces flat retrieval-augmented generation (RAG) with surprise-driven learning and built-in user isolation.

How to use Openclaw Fcma?

Clone the repository, install dependencies with pip install -e ".[dev]", and add the server to Claude Desktop’s claude_desktop_config.json using python -m openclaw.mcp_server. After restarting Claude, use any of the 28 MCP tools—like memory_store, mind_add_node, library_upload, or user_register—to store and recall memories. The server can also run in HTTP mode with --transport http.

Use cases of Openclaw Fcma

• Give Claude persistent memory across conversations—remember user names, projects, and preferences.
• Store and semantically search documents (PDF, text, code) with two-stage retrieval and re-ranking.

FAQ from Openclaw Fcma

What dependencies does Openclaw Fcma require?

Python 3.10+, FAISS, SQLAlchemy, Neo4j (for knowledge graph), and optional libraries for document ingestion. All dependencies are installed via pip install -e ".[dev]".

Where is data stored?

Data is stored locally under a data/ directory: SQLite database (openclaw.db), FAISS vector indexes (journal/, library/), Markdown session summaries (ledger/), and knowledge graph exports (graph_exports/). All paths are configurable via environment variables.

How does authentication work?

Openclaw Fcma uses JWT tokens with 24-hour expiry, auto-generated API keys (fcma_xxxx…), salted SHA-256 password hashing, and sliding-window rate limiting (default 60 requests per minute, configurable via FCMA_RATE_LIMIT).

What transports does the MCP server support?

The server supports stdio transport (default) and HTTP transport (--transport http). Use the MCP Inspector for debugging with mcp dev openclaw/mcp_server.py.

Can I export or delete my data for GDPR compliance?

Yes. The tools user_data_export and user_data_delete allow full export and cascade deletion of all user data, with an audit trail available via audit_log.
