This reference MCP server adds production-grade, privacy-first long-term memory with automatic PII sanitization, differential privacy and signed Neural Handover — all locally.</p> <h2> The Identity Crisis of AI Agents </h2> <p>Every time an agent starts a new session, it forgets everything. Context windows are temporary. Long-term memory is either non-existent or dangerously insecure.</p> <p>The Model Context Protocol (MCP) gives agents powerful tools — but still lacks a standardized, secure way to persist memory across sessions.</p> <p>Synapse Layer fixes this.</p> <h2> Synapse Layer – Zero-Knowledge Memory for MCP </h2> <p><strong>Synapse Layer</strong> is an open-source (Apache 2.0) memory infrastructure that turns any MCP-compatible agent into a persistent, privacy-first system.</p> <p>It exposes two simple MCP tools:</p> <ul> <li><code>store_memory(content, confidence, metadata)</code></li> <li><code>recall_memory(query, top_k)</code></li> </ul> <p>Every operation goes through a <strong>4-layer Cognitive Security Pipeline</strong>:</p> <ol> <li> <strong>Semantic Privacy Guard™</strong> – Automatic PII sanitization (12+ patterns)</li> <li> <strong>Intelligent Intent Validation™</strong> – Auto-categorization + self-healing</li> <li> <strong>Differential Privacy</strong> – Calibrated Gaussian noise (ε-DP)</li> <li> <strong>Persistence-First Neural Handover™</strong> – HMAC-signed context transfer</li> </ol> <p>Everything runs <strong>locally</strong>. Zero external calls. True zero-knowledge.</p> <h2> MCP Reference Implementation (PR #1129) </h2> <p>Submitted as official reference server:</p> <ul> <li>Repo: <a href="https://github.com/SynapseLayer/synapse-layer/tree/main/examples/mcp-secure-memory" rel="noopener noreferrer">https://github.com/SynapseLayer/synapse-layer/tree/main/examples/mcp-secure-memory</a> </li> <li>Registry PR: <a href="https://github.com/modelcontextprotocol/registry/pull/1129" rel="noopener noreferrer">https://github.com/modelcontextprotocol/registry/pull/1129</a> </li> </ul> <p>Works with Claude Desktop, LangChain, CrewAI and MCP Inspector.</p> <h2> Quick Start (Claude Desktop) </h2> <div class="highlight js-code-highlight"> <pre class="highlight plaintext"><code> json { "mcpServers": { "synapse-secure-memory": { "command": "python", "args": ["path/to/server.py"] } } } Why This Matters Synapse Layer is the missing infrastructure layer the MCP ecosystem needs: secure, portable, and production-ready.
