It is especially valuable in RAG pipelines, research agents, and competitive intelligence workflows where you need focused, token-efficient content. The BM25 budget mode is uniquely useful when you have a strict token ceiling and a specific query focus. Prefer this over generic web scrapers when token cost savings and ROI proof are important, or when you need structured/skeleton output rather than raw HTML.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-10-21T07:25:47.857Z","isFirstParty":false,"canonicalSlug":"mcp-security-agentdiet-dev-web-url-context-compressor-with-bm25-895d8141"}
