Make PDF Agent MCP remote-ready

[vlad-ds]

Summary

The PDF Agent MCP currently works well as a local MCP server but needs modifications to function as a remote MCP server. This involves adding network transport capabilities and handling remote file access patterns.

Current State

• ✅ Works perfectly as local MCP via stdio transport
• ✅ All PDF processing tools functional locally
• ❌ Not configured for remote MCP deployment

Requirements for Remote MCP

Network Transport

• Add HTTP/WebSocket transport support alongside stdio
• Implement proper CORS handling for web clients
• Add authentication/authorization if needed
• Handle network timeouts and retries

File Access Patterns

• Support for file uploads via HTTP endpoints
• Handle base64-encoded PDF data in requests
• Add temporary file management for uploaded PDFs
• Implement file cleanup after processing

Configuration Changes

• Add environment-based configuration
• Support different transport modes (stdio vs network)
• Add logging for remote debugging
• Handle different security contexts

API Considerations

• Ensure all tools work with remote file references
• Add file size validation for uploads
• Implement proper error handling for network issues
• Consider rate limiting for remote usage

Technical Implementation

The MCP SDK supports multiple transports, so we need to:

1. Transport Layer: Add HTTP/WebSocket transport options
2. File Handling: Modify file resolution to handle uploaded/remote files
3. Security: Add appropriate security measures for remote access
4. Deployment: Create deployment configurations (Docker, etc.)

Success Criteria

• Can be deployed as a remote MCP server
• All existing PDF tools work with remote files
• Proper error handling for network scenarios
• Documentation for remote deployment

Priority

Medium - This would significantly expand the use cases for PDF Agent MCP by enabling remote AI agents to process PDFs.
