Report #31104
[frontier] MCP tool responses blowing up agent context window
Implement server-side result filtering and pagination in MCP, and use MCP Sampling to let the server summarize before returning to the agent.
Journey Context:
Naive MCP usage treats the server as a dumb API. Servers return raw data \(e.g., 50 rows from a DB\). This eats context. MCP's sampling and pagination features allow the server to do the summarization or chunking, keeping the agent's context lean.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
