What it can do

  • Record Graph Memory: Create or merge user memory from conversation context (journal notes, preferences, plans, reflections, and ongoing personal/project context). Not intended for one-off calculations
  • Get Memory: Retrieve a specific memory by ID.
  • List Memories: List memories to review and pick targets for follow-up actions. Use this for recent/latest/today requests; follow nextCursor while hasMore is true.

How to connect

How to connect empirical to Claude

The server address to paste into Claude settings:

https://empirical--matt-ha7x.run.tools

  1. Open Claude (claude.ai or the desktop app).
  2. Go to Settings → Connectors.
  3. Click Add custom connector.
  4. Paste the server address copied below into Remote MCP server URL and click Add.
  5. In a chat, click + → Connectors and switch the new connector on.

Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

Authorization

After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

How to connect empirical to ChatGPT

The server address to paste into ChatGPT settings:

https://empirical--matt-ha7x.run.tools

  1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
  2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
  3. Open Settings → Connectors and click Create.
  4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
  5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
  6. In a new chat open + → Apps/Connectors and enable the connector.

OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

Authorization

On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

How to connect empirical to Cursor

The server address to paste into Cursor settings:

https://empirical--matt-ha7x.run.tools

Fastest: click Open in Cursor below and confirm the prompt.

Manually:

  1. In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
  2. Paste the JSON copied below into ~/.cursor/mcp.json (per project: .cursor/mcp.json in the repo root).
  3. Save the file. The server appears in the MCP list; authorize it there if asked.

Authorization

If the service needs sign-in, an authorize button appears next to the server in the MCP list.

Server tool list (15)

Raw names from tools/list. Only developers need these.

record_graph_memoryCreate or merge user memory from conversation context (journal notes, preferences, plans, reflections, and ongoing personal/project context). Not intended for one-off calculations, general knowledge answers, weather, or web lookup results.
get_memoryRetrieve a specific memory by ID.
list_memoriesList memories to review and pick targets for follow-up actions. Use this for recent/latest/today requests; follow nextCursor while hasMore is true.
query_memoriesSearch previously stored personal memories by semantic query and/or filters (category, tags, dates, location, graph fields). Use only when the user asks about their saved context; not for weather, web lookup, or general knowledge. When the user asks for ALL records of a specific kind (e.g. "all my period data", "my complete workout history"), populate the tags field with the relevant topic so every matching record is returned rather than a ranked subset.
get_memory_neighborsGet related memories and edges for a memory node (incoming, outgoing, or both).
update_memory_relationshipsAdd, remove, or replace relationships on a memory node.
add_note_by_queryAppend a note to an existing stored memory resolved by semantic query or explicit memoryId. Memory-editing only; not for external information tasks. If the target memory was created earlier in this same conversation, pass its memoryId instead of query -- search indexing can lag a few seconds behind a fresh write.
update_memory_by_queryUpdate an existing stored memory resolved by semantic query or explicit memoryId. Memory-editing only; not for external information tasks. If the target memory was created earlier in this same conversation, pass its memoryId instead of query -- search indexing can lag a few seconds behind a fresh write.
delete_memory_by_queryDelete a stored memory resolved by semantic query or explicit memoryId (requires confirm=true). Use only when user explicitly asks to remove their memory. If the target memory was created earlier in this same conversation, pass its memoryId instead of query -- search indexing can lag a few seconds behind a fresh write.
memory_usage_guideRead the memory usage policy for when to create, query, update, or delete memories.
get_empirical_policyRead the authenticated user's normalized Empirical behavior policy. This is read-only and reflects the current installer/settings preferences.
get_userGet the authenticated Empirical profile/account context for the connected user. Not a source for weather, web facts, or general knowledge.
list_workspacesList selectable workspaces for this OAuth client (Default Workspace first).
get_current_workspaceGet current workspace selection for this OAuth client.
set_current_workspaceSet current workspace selection for this OAuth client.
