How do I use Paperzilla MCP with Claude? - Paperzilla Docs Portal

Add Paperzilla as a custom connector in Claude. The short version:

Create or copy your MCP API key from the dashboard.
In Claude, open Settings > Connectors.
Add a custom connector named Paperzilla.
Use https://paperzilla.ai/api/mcp/?key=pzmcp_... as the connector URL.
After setup, switch the connector to Always allow so Claude can use the tools without asking on every call.

Once connected, Claude can use:

projects_list
projects_get
feed_get
feed_atom_url
paper_get
paper_markdown
