Sierra’s internal agent hit the same bottleneck: getting the right context
blaizedsouza · x · 2026-07-23
This article examines the “MCP Gateway” problem behind Sierra’s internal agent, Pinecone: giving an agent the right context at the right time.
The core point is that even strong models fail when they cannot reach the information they need. The piece frames context access as an infrastructure challenge for agents, not just a prompting problem, and explores how a gateway layer can route and expose the right internal data.
