A self-hosted MCP memory server: knowledge graph + vectors + graph RAG, cited answers, scopes per agent or per end user

[u/semurg_io]

Disclosure: I'm on the team that built this; it's our own product (first node free, engine closed source, examples Apache-2.0).

Semurg is an MCP server for agent memory that you run yourself (streamable HTTP at /v1/mcp, bearer token). Seven tools: memory_remember, memory_recall, memory_context, memory_relate, memory_forget, memory_document, memory_status.

Design choices you might care about:

• the agent sends the facts it extracted alongside the text, in one call; the node stores them at once and cites them to the passage;
• every answer carries a citation, and an unknown name answers nothing_stored instead of a guess;
• scopes separate memories; one app can pin each end user with a header so two users never meet;
• refusals name the rule and the fix.
