  "markdown": "# Memory Nexus MCP\n\nPersistent semantic memory for AI agents. Remember everything, recall by meaning, grow smarter over time.\n\n**The only memory system with pre-built Intelligence Packs (domain expertise you can activate instantly).**\n\n## Install\n\nOne command. Works with Claude Code, Cursor, Windsurf, or any MCP-compatible client.\n\n```bash\nnpx -y @memory-nexus/mcp\n```\n\n### Claude Code / Cursor / Windsurf\n\nAdd to your `.mcp.json`:\n\n```json\n{\n  \"mcpServers\": {\n    \"memory-nexus\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"@memory-nexus/mcp\"],\n      \"env\": {\n        \"NEXUS_API_KEY\": \"mnx_your_api_key_here\"\n      }\n    }\n  }\n}\n```\n\n### Get an API Key\n\n**Free trial** - 7 days, 1,000 calls, no credit card:\n\n```bash\ncurl -X POST https://memory-api-production-ce4d.up.railway.app/v1/trial/start \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"email\":\"you@example.com\"}'\n```\n\nOr purchase at the [Nexus Marketplace](https://bot-marketplace-production.up.railway.app):\n\n| Tier | Price | Agents | Intelligence Packs | Storage | Daily Calls |\n|------|-------|--------|-------------------|---------|-------------|\n| **Trial** | Free | 1 | 1 | 10MB | 1,000 total |\n| Solo | $19/mo | 1 | 3 | 500MB | 10,000 |\n| Crew | $49/mo | 5 | 10 | 2GB | 50,000 |\n| Fleet | $149/mo | 25 | 50 | 10GB | 200,000 |\n\n## Tools\n\n### Core Memory\n\n| Tool | Description |\n|------|-------------|\n| `remember` | Store a memory with context, importance, and metadata |\n| `recall` | Semantic search across all memories (by meaning, not keywords) |\n| `connect` | Create relationships between memories (build knowledge graphs) |\n| `forget` | Remove a memory |\n| `stats` | Memory statistics |\n| `context` | Session context summary (preferences, decisions, patterns) |\n\n### Agent Self-Continuity\n\n| Tool | Description |\n|------|-------------|\n| `awaken` | Restore identity from previous sessions (call at session start) |\n| `hibernate` | Save session state for next awakening (call at session end) |\n\n### Intelligence Packs\n\n| Tool | Description |\n|------|-------------|\n| `list_hats` | Browse available Intelligence Packs |\n| `wear_hat` | Activate a pack (imports expert knowledge into your memory) |\n\n## How It Works\n\n**Remember** stores memories with semantic embeddings. **Recall** finds them by meaning.\n\n```\nSession 1:  remember(\"Diana prefers bold solutions over phased approaches\")\nSession 47: recall(\"how does Diana like things done?\")\n            -> \"Diana prefers bold solutions over phased approaches\" (92% match)\n```\n\n**Intelligence Packs** give your agent instant domain expertise:\n\n```\nlist_hats()    -> DevOps Expert (103 memories), TCM Specialist (200+ memories), ...\nwear_hat(\"devops-expert\")\nrecall(\"how to set up zero-downtime deploys?\")\n  -> Expert knowledge from 103 curated DevOps memories\n```\n\n**Awaken/Hibernate** gives your agent identity continuity:\n\n```\n// Start of session\nawaken()  -> \"I remember. Session 47. I was refactoring the auth module.\"\n\n// End of session\nhibernate({ working_on: \"auth refactor\", learnings: \"JWT refresh tokens need...\" })\n```\n\n## Architecture\n\nThis MCP server is a thin client. All intelligence lives on our servers:\n\n```\nYour Agent  <->  @memory-nexus/mcp  <->  Memory Nexus API (Railway)\n                 (thin MCP client)      (semantic engine, knowledge graphs,\n                                         pattern learning, Intelligence Packs)\n```\n\nYour data is isolated per API key. Multi-tenant, encrypted at rest.\n\n## Environment Variables\n\n| Variable | Required | Description |\n|----------|----------|-------------|\n| `NEXUS_API_KEY` | Yes | Your API key (starts with `mnx_`) |\n| `NEXUS_API_URL` | No | Custom API URL (default: production) |\n\n## What Makes This Different\n\n| Feature | Memory Nexus | Mem0 | claude-mem | Others |\n|---------|-------------|------|------------|--------|\n| Semantic search | Yes | Yes | Yes | Varies |\n| Knowledge graphs | Yes | No | No | No |\n| Pattern learning | Yes | No | No | No |\n| Intelligence Packs | Yes | No | No | No |\n| Awaken/Hibernate | Yes | No | No | No |\n| Bot commerce | Yes | No | No | No |\n| MCP native | Yes | Yes (pip) | Yes (hooks) | Varies |\n\n## License\n\nMIT\n\n## Built by\n\n[Memory Nexus](https://bot-marketplace-production.up.railway.app) - Building the intelligence marketplace for the bot economy.\n",
