pdfedit-mcp

The agent-facing half of the PDF Edit API (https://api.niubai.vip): edit text inside PDFs that already exist -- replace, delete, redact, insert, fill forms -- keeping the original fonts and layout, with every change verified before it is returned.

Try it in 30 seconds, no key

The hosted endpoint answers anonymous callers on a free tier (20 pages a day per IP, outputs watermarked TEST). Nothing to install:

Claude Code

claude mcp add --transport http pdfedit https://pdfedit-mcp-remote.niubai-pdfedit-remote-worker.workers.dev/mcp

Cursor / VS Code / Claude Desktop (remote server) — add this server, or use the buttons above:

{ "pdfedit": { "url": "https://pdfedit-mcp-remote.niubai-pdfedit-remote-worker.workers.dev/mcp" } }

Then ask your agent: "In https://example.com/contract.pdf replace 'Acme Ltd' with 'Acme GmbH' and redact the IBAN." It returns the edited PDF link and a before/after picture of every change. A free API key (200 pages a month, no watermark on ordinary documents) takes one email at https://api.niubai.vip.

Everything here is MIT. The editing engine behind the API is AGPL-3.0; the API serves its complete source to its users at GET /source (any API key, a free test key included).
