Save from ChatGPT or Claude.

Reader tools

• upload_markdown — Save to PsychArch Reader. Saves a document and counts toward your daily upload limit.

• upload_file — Save file to PsychArch Reader (ChatGPT only). Transfers a ChatGPT file directly: UTF-8 Markdown or plain text, or a PNG, JPEG, GIF, or WebP image, up to 1 MiB. PDF and other formats are unsupported. Reader checks quota before downloading; each save counts toward your daily upload limit.

• whoami — Check Reader connection. A read-only, no-argument check that returns your current subject, granted Reader scopes, and canUpload, plus tier, uploadsUsed, uploadLimit, and uploadsResetAt. It creates no document and consumes no upload quota. canUpload reports upload permission, not remaining quota or a guarantee that an upload will succeed.

All tools require the existing reader.upload MCP grant. whoami needs no additional OAuth scope.

ChatGPT

1. Open the custom MCP form

   Sign in to ChatGPT. Open Plugins → Add → Create custom MCP server.

2. Enter the Reader connection

   Set Name to PsychArch Reader, paste the server URL above, and leave Authentication set to OAuth. The description and icon are optional.

3. Check the OAuth settings

   Open Advanced OAuth settings and wait for discovery. Keep Client Identifier Metadata Document (CIMD) selected. No client ID or secret needs to be entered manually.

   Keep reader.upload selected under Default scopes. Enter offline_access in Base scopes so the connection can stay signed in. If OIDC enabled is checked, set OIDC scopes supported to openid profile email. Leave the discovered endpoint URLs unchanged.

4. Connect your account

   Review and check I understand and want to continue, then select Create as a plugin → Continue to PsychArch Reader. Sign in to PsychArch if prompted, review the requested permissions, and select Allow access.

   Back in ChatGPT, open Plugins → Personal → PsychArch Reader. Your account should appear under Connected accounts. Open the Reader app entry to see upload_markdown, upload_file, and whoami, or select Try in chat. Ask the assistant to call whoami for a safe connection check before saving.

Claude

1. Add a custom connector

   Sign in to Claude. Open Customize → Connectors → Add → Add custom connector.

2. Enter the Reader connection

   Set Name to PsychArch Reader and MCP server URL to the server URL above. Select Continue and let Claude check the server.

3. Keep the detected sign-in options

   Choose Sign in now and Use Claude’s published identity. Leave request headers empty. Under Advanced, keep Streamable HTTP. Select Add, then Connect.

4. Sign in and check the tools

   Sign in to your PsychArch account if prompted. Review the upload and continued-access permissions, then select Allow access. Claude should return to the connector page with Save to PsychArch Reader (upload_markdown) and Check Reader connection (whoami) under Tool permissions. Choose Needs approval for confirmation on each save, or Always allow if you prefer. Enable Reader in a chat and ask the assistant to call whoami for a safe connection check before saving.

Claude can save text with upload_markdown. Direct transfer of attached or generated files is unavailable; saving text through the assistant does not preserve the original file bytes.

Check your connection

In ChatGPT, choose Try in chat. In Claude, start a chat and enable PsychArch Reader from + → Connectors. Then ask:

Call PsychArch Reader’s whoami to check my connected account and Reader permissions.

This check creates no document and consumes no upload quota. A successful response confirms the connected account and permissions; canUpload: true does not confirm that quota remains. Compare uploadsUsed with uploadLimit for today’s remaining slots; usage resets at uploadsResetAt. No additional OAuth scope is needed beyond the existing reader.upload MCP grant.

Save your first document

In ChatGPT, choose Try in chat on the Reader plugin. In Claude, start a chat and enable PsychArch Reader from + → Connectors. Then ask:

Save this response to PsychArch Reader as Markdown, titled “Reading notes”.

Approve the save if prompted. The assistant returns a reading link; open it with the same PsychArch account. Each save counts toward your daily upload limit. Documents expire after three days by default, and you can ask for a different supported retention time.

For a file in ChatGPT, attach or generate a supported file and ask “Save this file directly to PsychArch Reader.” Approve the transfer if prompted. The assistant returns a reading link without copying the file into chat. If the temporary download URL expires, attach the file again and retry.

Already connected?

Use the existing PsychArch Reader entry instead of adding the URL again. If sign-in expires, reconnect from that entry. If a tool is missing in a chat, check that Reader is enabled for that conversation. If its tool list differs from the list for your assistant above, refresh the Reader tool list or reconnect the existing entry, then check with whoami.

To stop access, disconnect Reader in ChatGPT’s plugin settings or Claude’s connector settings.
