Connect Erudio MCP to ChatGPT.
Add Erudio to ChatGPT as a custom MCP server, for Business and Enterprise workspaces. Two servers: https://mcp.erudio.com/free needs no sign-in and searches, previews and orders reports; https://mcp.erudio.com/mcp reads the reports you bought.
Who can set it up
Custom MCP servers are available in ChatGPT on the web for Business, Enterprise and Edu workspaces. On Business, only admins and owners can add and publish one; on Enterprise and Edu, an admin grants the right. Availability on Plus and Pro was not confirmed in OpenAI's documentation when this page was checked.
Find and order reports
Search reports, preview them, order, and read the free report. No key, account or sign-in.
Add the free server
- In ChatGPT, open Plugins and choose + > Add custom MCP server.
- Name it Erudio, describe it as "Clinician commentary reports on clinical trials", and enter https://mcp.erudio.com/free as the Server URL.
- Set authentication to No authentication, confirm, then Create as a plugin and install it.
Read the reports you bought
A license key starts erudio_ and comes with a purchase: get_order returns it once an order is paid, and the buyer gets their account key by email. Lost keys are sent again from erudio.com/keys.
Sign in to read your reports
- Add another custom MCP server with https://mcp.erudio.com/mcp as the Server URL.
- Set authentication to OAuth. ChatGPT registers itself with Erudio; no client ID or secret is needed.
- Sign in with the email you bought with, or your organization's registered account.
Check it works
- Ask:
Use Erudio to find reports on KRAS G12C lung cancer trials.
The agent calls search_reports and lists matching reports with their prices. - Ask:
Read Erudio's free IDeate-Lung01 report and summarize what clinicians disagree about.
On the free server, the agent calls read_report with "erudio-nct05280470" and quotes the report's findings with their sources.
Every tool and what it returns: For agents. Error codes: Developers.
Questions
Can I use my license key in ChatGPT?
Not in ChatGPT: it connects with OAuth or with no authentication, and does not send a custom header. Sign in with the email you bought with, or use the free server.
A new Erudio tool is missing. Why?
ChatGPT keeps a snapshot of the server's tools after an admin approves it. When Erudio adds tools, an admin refreshes the plugin to see them.
Can I sign in with a Microsoft account?
Erudio's sign-in page uses Google accounts, with the email you bought with or the one your organization registered. If your work email is not a Google account, use your license key instead.
