No legal entity named in the terms or privacy policy.\n\n## Before you call either\n\n### Memory (MCP reference server)\n\n1. Set `MEMORY_FILE_PATH` to an absolute path. The default sits inside the npx cache\n2. Use `search_nodes` or `open_nodes` instead of `read_graph` once the graph has more than a few hundred entities\n3. Make memory writes one at a time. Parallel calls in one turn can overwrite each other in 2026.8.31\n4. Create both entities before `create_relations`. A missing endpoint fails the whole batch\n5. Keep observations short and factual. They come back verbatim in every later read\n\n### Supermemory API + MCP\n\n1. Use one stable `containerTag` per user and a `customId` per session\n2. Poll the document until `status` is `done` before searching for what you just added\n3. Treat a 402 on search or profile as out of credit, not as a bug\n4. Run the prompt-based mass forget with `dryRun` first\n5. Call who_am_i on the MCP to see which spaces you can write to before adding\n\n## Questions\n\n### Which is better for AI agents, Memory (MCP reference server) or Supermemory API + MCP?\n\nSupermemory API + MCP scores 63.6 (B) on agent readiness against Memory (MCP reference server)'s 54.2 (C), and leads in 5 of 7 scored categories. Memory (MCP reference server) leads on payments \u0026 pricing and transparency \u0026 trust.\n\n### Do Memory (MCP reference server) and Supermemory API + MCP need an API key?\n\nMemory (MCP reference server) needs no key. Supermemory API + MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call Memory (MCP reference server) and Supermemory API + MCP without installing anything?\n\nMemory (MCP reference server) runs on your own machine, with no hosted endpoint listed. Supermemory API + MCP has a hosted endpoint at https://api.supermemory.ai.\n\n### Are Memory (MCP reference server) and Supermemory API + MCP open source?\n\nYes. Memory (MCP reference server) is open source (MIT and Apache-2.0). Supermemory API + MCP is open source (MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/memory-reference-server-vs-supermemory.json, and with the fewest tokens: https://www.anchorterminal.com/compare/memory-reference-server-vs-supermemory.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"memory-reference-server\", \"b\": \"supermemory\"}`.
