Connect your assistant: ChatGPT, Claude, Claude Code or Codex

Connect your assistant to Eigma once. It takes about a minute and needs an Eigma account. In any conversation after that, you just say “organize this into Eigma,” and that is it. The conversation is turned into clean wiki pages, waiting in Eigma for you to review.

Pick your assistant

ChatGPT

1. Open Settings, then Plugins.
2. Turn on Developer mode. Until you do, there is no way to add a plugin of your own, which is where most people get stuck.
3. Click Browse plugins, then the + to add one.
4. Give it the name Eigma and paste the address into the server URL field.
5. ChatGPT sends you to sign in with Eigma. Approve the connection, and you are done.

Claude

1. Open Customize, then Connectors.
2. Click +, then Add custom connector.
3. Paste the address and click Add.
4. Claude sends you to sign in with Eigma. Approve the connection.
5. Open a chat, click the + at the bottom left, choose Connectors, and switch Eigma on.

On the free plan you can have one custom connector at a time. That is enough for Eigma, but if you already have one, you will need to remove it first.

Claude Code

Add the server, then sign in:

claude mcp add --transport http --scope user eigma https://my.eigma.app/api/mcp
claude mcp login eigma

The second command opens a browser window for you to sign in to Eigma and approve the connection. claude mcp get eigma shows the status afterwards.

Codex

Add the server, then sign in:

codex mcp add eigma --url https://my.eigma.app/api/mcp
codex mcp login eigma

The second command opens a browser window for you to sign in to Eigma and approve the connection. codex mcp list shows the status afterwards.

Now use it

In any conversation, just say “organize this into Eigma” (or “save this to Eigma”). Your assistant handles the rest.

Then open Eigma and click the mailbox at the top of the Ingest page. The conversations you sent are waiting there. Open one to see what it pulled out, and keep what you want. Nothing goes into your wiki until you say so.

If something does not work

• The menus do not look like this. They move around, and this page will always be a little behind. The fastest way through is to ask the assistant itself: “how do I add a custom MCP server?”
• The sign-in page says the link expired. It sat open too long. Go back and start the connection again; it works the second time.
• It used to work, and now the assistant cannot find Eigma’s tools. Assistants keep the tool list they were handed when you connected, so an update on our side can leave an old copy sitting there. Remove the Eigma connector, add it again with the same address, and then start a new conversation: a chat that is already open keeps the stale list. In Claude Code or Codex, restarting usually picks up the new tools on its own; if it does not, run claude mcp remove eigma or codex mcp remove eigma and add it back.
• Claude says it is connected, but asking does nothing. Check the connector switch for that conversation, at the bottom-left + button.
• You are on Claude’s free plan and cannot add it. One custom connector at a time; remove the other one first.

Connect once, then let the chat you are already in feed the wiki you own.
