Cursor

Four lines of JSON and one browser approval. After that the Cursor Agent can search, write, and cite your memory graph in every workspace you open — with no key stored in the repo.

Cursor

MCP servers moved out of Cursor Settings. Open Cursor Settings and click Open Customize on the banner.

The same thing, written down

Cursor moved plugins, MCPs, skills, and rules into a single Customize surface, so older guides point at a settings pane that no longer exists. This is the current path.

Set up Cursor in 5 steps

No API keys to paste, no glue code — sign in once and your agent keeps the memory.

The config, to copy

Put this in ~/.cursor/mcp.json for every project, or .cursor/mcp.json inside a repo to scope it to that workspace.

~/.cursor/mcp.json

{
  "mcpServers": {
    "memuron": {
      "url": "https://api.memuron.com/mcp"
    }
  }
}

Do not add an Authorization header or an API key here. Memuron authenticates Cursor through OAuth with dynamic client registration — a hand-written header will be rejected and the server will sit in Needs Attention.

What the Agent can do once connected

Every action is a typed MCP tool in the Agent's picker. Destructive calls carry a confirmation flag.

memuron_list_spaces

Discover which spaces exist before guessing a path.

memuron_query

Pipe semantic search, traversal, and regex over the graph.

memuron_get

Fetch one memory and its links once you have an ID.

memuron_ingest

Queue content for the Guardian to create, update, or link.

memuron_updateconfirm

Patch content or scope on a memory you already found.

memuron_deleteconfirm

Remove a memory — never without an explicit confirmation.

memuron_document_source

Resolve any chunk back to the file and page it came from.

memuron_job_status

Poll an async ingest until the Guardian commits or rejects it.

For folder sync, CI ingest, and shell queries alongside MCP, see the Memuron CLI.

When something looks wrong

Stuck in Needs Attention. Click Authenticate on the row — adding the server does not start the OAuth flow by itself.
Error – Show Output. Usually a JSON syntax error in mcp.json, most often a trailing comma. The output panel names the line.
Tools listed but never called. The Agent picks tools on its own. Ask for memory explicitly, or add a rule pointing at Memuron — see the AGENTS.md pack.
Empty results. You approved a different organization. Check the active org in the console and reconnect.
