DeepSeek Harness MCP tool search for large catalogs: 1,000 MCP tools behind 2 MCP-facing schemas, exact-schema calls, allow/deny controls, and a local calculator.

About

Website · Local schema calculator · Install rc.9 Shrink large MCP catalogs to a two-tool model surface. MCP Lens lets DeepSeek Harness search and call 1,000 remote tools through two stable model-facing interfaces. Instead of sending every tool schema on every turn, it reveals exact schemas only for a small ranked set when a tool is actually needed. If this keeps a large MCP catalog manageable for you, star the repository so more DeepSeek Harness users can find it. Why users install it: - Spend less on input-heavy turns: in the dated three-task pilot, estimated DeepSeek V4 Flash cost fell from $0.0307204 to $0.0034707. -

✨ Key Features

  • Spend less on input-heavy turns: in the dated three-task pilot, estimated DeepSeek V4 Flash cost fell from $0.0307204 to $0.0034707.
  • Keep more room for the real task: the same pilot reduced request/header.tools JSON from 674,249 B to 27,401 B.
  • Retrieve more relevant covered calls: on a frozen MCP-Atlas-derived convenience holdout, Recall@5 rose from 0.062610 to 0.246656 across 304 untouched prompt
  • Avoid rebuilding the same search index on every query: rc.9 reuses the tokenized index for each Lens-owned frozen catalog and policy generation, then invalidate
  • Narrow the tool-choice surface: search reveals only a small ranked set of exact schemas, and the final server/tool is still gated by allowTools and `denyToo
  • Preserve completion in the tested pilot: both arms completed 3/3 tasks, while Lens used one extra search step.
