Processing large documents with AI agents can incur significant costs due to token limits, especially when documents are encoded or their text is extracted directly into the agent's context. A 2MB PDF, for instance, can cost nearly $0.30 to process inline, with the majority of tokens consumed by file I/O rather than actual reasoning. The Model Context Protocol (MCP) offers a more efficient alternative by allowing agents to delegate file processing to specialized services, drastically reducing token usage and cost. This approach, demonstrated with a 2MB PDF, cut token overhead from approximately 97,000 to 8,000, making the process ten times cheaper. AI
