Nocturne Memory MCP Server: Long-Term Memory for Your AI Assistant

• Reads a memory or a system view

  Opens one memory by its address, such as core://agent. Special addresses load boot memories, an index, recent changes, the keyword glossary or a health check.

  Try: “Read system://boot and tell me who you are.”

  Read · read_memory

• Saves a new memory

  Creates a memory under a parent address, with a priority and a trigger condition that says when it should come up.

  Try: “Remember that I prefer short answers, under core://my_user.”

  Write · create_memory

• Edits an existing memory

  Changes a memory by replacing a passage or appending text. There is no full-replace mode, and it can also reset priority and disclosure for one path.

  Try: “Add that I moved to Berlin to my profile memory.”

  Write · update_memory

• Removes a memory path

  Cuts one address to a memory permanently. If that would orphan child memories, it refuses and lists them first.

  Try: “Delete the outdated note at core://agent/old_note.”

  Delete · delete_memory

• Adds a second address to a memory

  Makes another address point to the same memory, with its own priority and trigger. It is not a copy, and children are mirrored.

  Try: “Add an alias for this memory under core://timeline.”

  Write · add_alias

• Adds or removes keyword links

  Binds keywords to a memory so a link to it shows when that word appears in other memories. It returns the current trigger list.

  Try: “Add the trigger "Nginx" to the server setup memory.”

  Write · manage_triggers

• Searches memories by keyword

  Runs full-text substring search over memory paths and content, optionally limited to one domain. It is not semantic search.

  Try: “Search my memories for "chapter 3" in the writer domain.”

  Read · search_memory

Watch out for

• It can delete memories, not just read them

  delete_memory permanently removes a memory path. The README says changes are backed up and can be reviewed and rolled back in the dashboard, so check there if something goes missing. github.com

• The assistant can rewrite its own memory

  create_memory, update_memory, add_alias and manage_triggers change what your assistant believes about you. Review changes in the dashboard from time to time. github.com

• A dashboard and REST API start with the server

  Stdio mode starts a local web server on 127.0.0.1 port 8233 and opens your browser by default. Without an API token, any program on your computer can reach it. Leave the host at 127.0.0.1. github.com

• Remote mode exposes your memories to the network

  If you set the host to 0.0.0.0 for remote access, the server refuses to start without an API token. Use a long random token and HTTPS. github.com
