What data it sees

Do you need an account

No: the server works without sign-in

A personal RAG database you build from chat. Store your knowledge, voice, and skills once; Claude and ChatGPT then create work that sounds like you. Connects as a remote MCP server (OAuth). Free during early access.

How to connect

How to connect MyAITwin to Claude

The server address to paste into Claude settings:

https://myaitwin--team-sw2r.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 MyAITwin to ChatGPT

The server address to paste into ChatGPT settings:

https://myaitwin--team-sw2r.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 MyAITwin to Cursor

The server address to paste into Cursor settings:

https://myaitwin--team-sw2r.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 (19)

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

add_knowledgeStore a piece of knowledge or a skill in your twin. Automatically tagged and embedded for search. The twin stores two fundamentally different things — knowledge (what the user knows: transcripts, decisions, ideas, observations) and skills (how they express things: their LinkedIn voice, email style, proposal structure, feedback frameworks). Treat skills as a significant moment — they codify craft.
add_reference_recordRecord a creation event after the user has produced something with the twin's help — pairs knowledge used + skill applied + output produced + the nuance of this specific case. The system prompt instructs you to offer this after significant creation tasks; call it once the user confirms.
add_from_urlFetch a URL, extract what's worth knowing, and store it. The twin analyses the page against your existing schema and reports what it found before confirming what was stored.
add_documentIngest a document by providing its text content. Chunks and stores with source tracking. Good for PDFs, notes, reports.
add_voice_noteIngest a voice note transcript. The twin extracts principles, decisions, and ideas — identifying what you said that's worth keeping, in your language. Source is tracked as voice note + date.
get_schemaShow what knowledge types exist in your twin, how many items of each type are stored, and the total knowledge base size.
add_schema_typeAdd a new knowledge type. Do this from Claude chat — no database access needed. The type is immediately available for storing knowledge.
update_schema_typeUpdate the description of an existing knowledge type.
search_twinSemantically search everything in your twin. Returns the most relevant items ranked by relevance, each with its source cited.
get_by_typeRetrieve all knowledge of a specific type, newest first.
get_by_tagRetrieve all knowledge with a specific tag.
search_for_creationUse this BEFORE any creation task ("help me write X", "I'm working on Y"). Runs two parallel searches and returns them separately: a SKILLS bucket (skill/voice/template — the craft layer) and a KNOWLEDGE bucket (knowledge/principle/brand/idea/resource — the material). Bring both into context before producing output. If the skills bucket is empty and `output_type` is set, this also increments a skill-gap counter; when count reaches 3 the response includes `skill_gap.skill_gap_threshold_reached: true` so you can prompt the user to codify a skill.
synthesisePull everything relevant on a topic and return structured, usable output — ready to turn into a brief, a slide, or a team handoff. Every source cited.
find_patternsAnalyse your stored knowledge and surface recurring themes — principles you repeat without naming, patterns in how you think. Especially powerful after adding several voice notes.
get_sourcesShow all documents, URLs, and voice notes that have been ingested — with what was extracted from each.
list_recentShow the most recently added knowledge items.
update_knowledgeEdit a stored knowledge item. Provide the item ID and the fields to change.
delete_knowledgeRemove a knowledge item from your twin. This is irreversible.
get_welcomeReturns the user's personalised session opener — a short message that surfaces twin state, recent activity, and current focus. Call this on the user's first message each session, before responding to anything else.
