It’s not just about passing prompts — in production systems like Ramp’s, they had to build a custom ETL pipeline to process data from their endpoints, and host a separate database to serve structured transaction data into the LLM context window effectively.
We’ve seen similar pre-processing strategies in many efficient LLM-integrated APIs — whether it’s GraphQL shaping data precisely, SQL transformations for LLM compatibility, or LLM-assisted data shaping like Exa does for Search.
PS: When building agents, prompt and context management becomes a real bottleneck. You often need to juggle dynamic prompts, tool descriptions, and task-specific data — all without blowing the context window or inducing hallucinations. MCP servers help solve this by acting as a "plug-and-play" prompt loader — dynamically fetching task-relevant prompts or tool wrappers just-in-time. This leads to more efficient tool selection, reduced prompt bloat, and better overall reasoning for agent workflows.
