Use pdfAssistant Inside Your AI Assistant
pdfAssistant connects directly to your AI assistant through the Model Context Protocol (MCP) — an open standard that lets AI models securely discover and execute external tools. Process, convert, merge, compress, redact, OCR, watermark, and encrypt PDFs without leaving your conversation. Authenticate in under 60 seconds with secure OAuth single sign-on.
Paid plan required · Not available on the free tier

Three steps. Under 60 seconds.
From a fresh AI client to a fully connected PDF toolbox in your conversation. See paid plans →
1. Link Your Account
Open your AI client's settings, add the pdfAssistant remote server endpoint, and click Link Account.
2. Secure OAuth Login
A popup opens. Log in with your pdfAssistant credentials via OAuth to authorize your AI assistant to use your tools and credits. Your passwords and API keys are never exposed.
3. Start Processing
Drop a document into your chat and describe what you need. Your assistant calls pdfAssistant's tools, processes the file in the cloud, and delivers the result in your conversation.
What You Can Do
Every PDF operation, exposed to your AI.
The complete toolset your AI assistant can call once pdfAssistant is connected via MCP.

Why MCP
From Document Comprehension to Document Manipulation
Most AI assistants can talk about a document — summarize it, extract key points, answer questions about its content. But they cannot safely perform structural modifications to the file itself. They cannot compress an oversized presentation, flatten form layers, redact sensitive data with regex patterns, or convert raw images into searchable text.
pdfAssistant bridges that gap. When connected via MCP, your AI moves from basic text comprehension to active document manipulation — with a professional-grade toolbox it can combine on the fly to handle real document workflows end to end.
Security & Privacy
Built for documents you can't afford to leak.
OAuth 2.0 authentication. TLS 1.3 in transit. Zero retention after the job completes.
24-Hour File Deletion
Uploaded files are processed in encrypted storage and permanently deleted within 24 hours of task completion — not stored long-term.
pdfAssistant Doesn't Train On Your Data
pdfAssistant never uses your documents, prompts, or extracted metadata to train AI models. Note: when you connect third-party LLMs (Claude, ChatGPT, Codex, etc.) over MCP, the content you share with them is subject to their own retention and training policies.
Encrypted in Transit
All file payloads and tool calls use TLS 1.3 encryption end-to-end.
Architecture
Built on Open Standards
pdfAssistant's MCP server runs on a high-performance Streamable HTTP transport architecture using the JSON-RPC 2.0 protocol. All connections route through a single secure endpoint:
https://chat.pdfassistant.ai/mcpAuthentication is handled via standard OAuth 2.0 — your credentials are never exposed to your local LLM environment or third-party interfaces.
