ChatGPT plugin package
Upload ../historical-figure-chatgpt-plugin.zip in ChatGPT: Plugins → + → Create plugin. It bundles:
plugin.json: the manifest (Agent Plugins 1.0.0 portable format).mcp.json: the remote MCP server athttps://historical-figure-delta.vercel.app/api/mcp(Streamable HTTP, no authentication).skills/historical-figure/SKILL.md: the ChatGPT skill, copied fromskills/chatgpt/SKILL.mdon theassistant-integrationbranch.
ChatGPT accepts an MCP server only in the first upload of a plugin, so keep the server and the skill in one package.
Rebuild the zip after changing any of these files:
cd skills/chatgpt-plugin
rm -f ../historical-figure-chatgpt-plugin.zip
zip -X -r ../historical-figure-chatgpt-plugin.zip plugin.json mcp.json skills
The /api/mcp endpoint exists only in deployments that include the assistant-integration code.
