# 관찰 로그 01 - exa / `web_search_exa` - 출처: `MCP_툴_호출_통신_로그_(JSON-RPC) (1).pdf` - 원본 생성 시각: 2026-07-13 17:10:33 UTC - 성격: Agent Builder 솔루션에서 수행한 관찰용 실행 로그. 본 문서는 구현 계약이나 테스트 fixture가 아니다. ## 헤더 및 실행 메타데이터 | 항목 | 원본 기록 값 | |---|---| | transport type | `mcp-http` | | request_id | `045992d3-9683-4409-9613-e355a3eb05e1` | | tool_uid | `f44207bd-9afb-4bbe-88d7-1cadf9e2779b` | | Tool version | `2.0` | | 실행 시각 | 2026-07-13 16:53:16 UTC | | 결과 | ok · 1896ms · truncated=False | | JSON-RPC 프레임 수 | 5 | | lifecycle | `initialize → notifications/initialized → tools/call` | ### HTTP 헤더 기록 범위 원본 PDF에는 개별 HTTP request/response header 값이 기록되어 있지 않다. 원본 표의 `request_id`, `tool_uid`, `version`은 실행 메타데이터이며 HTTP header라고 단정하지 않는다. 원본 공통 안내에는 시크릿 및 인증 header가 로깅 전에 `[REDACTED]`로 마스킹되었다고 명시되어 있다. 따라서 Authorization, `Mcp-Session-Id` 등 실제 HTTP header 값은 이 문서에 포함하지 않는다. ## JSON-RPC 통신 전문 아래는 원본 PDF의 JSON-RPC 프레임을 순서대로 옮긴 전사본이다. 긴 `result.content[].text` 문자열은 PDF의 시각적 줄바꿈을 보존했으므로, 이 블록 전체를 기계 실행용 단일 JSON payload로 사용하지 않는다. ```text 16:53:16 요청 → initialize { "jsonrpc": "2.0", "id": 1, "method": "initialize", "params": { "protocolVersion": "2025-06-18", "capabilities": {}, "clientInfo": { "name": "toolbox-executor", "version": "0.1.0" } } } 16:53:16 ← 응답 initialize { "result": { "protocolVersion": "2025-06-18", "capabilities": { "tools": { "listChanged": true }, "prompts": { "listChanged": true }, "resources": { "listChanged": true } }, "serverInfo": { "name": "exa-search-server", "title": "Exa", "version": "3.2.1", "websiteUrl": "", "icons": [ { "src": "", "mimeType": "image/png", "sizes": [ "32x32" ] } ] } }, "jsonrpc": "2.0", "id": 1 } 16:53:16 요청 → notifications/initialized { "jsonrpc": "2.0", "method": "notifications/initialized" } 16:53:17 요청 → tools/call { "jsonrpc": "2.0", "id": 3, "method": "tools/call", "params": { "name": "web_search_exa", "arguments": { "query": "most popular useless github repository stars useless repo", "numResults": 10.0 } } } 16:53:18 ← 응답 tools/call { "result": { "content": [ { "type": "text", "text": "Title: btahir/uselesshooks\nURL: N/A\nAuthor: N/A\nHighlights:\n# btahir/us\n...\n- Stars: 125\n- Forks: 9\n- Watchers: 125\n- Open issues: 3\n- License: MIT License\n- Default branch: main\n- Created: 2022-12-18T03:03:19Z\n\n---\n\n Title: Useless-Garbage-Institute/useless-garbage\nURL: 2015-08-27T22:14:06.000Z\nAuthor: N/A\nHighlights:\n# Repository: Useles s-Garbage-Institute/useless-garbage\n...\nThe most profoundly useless javascript library ever invente d.\n...\n- Stars: 6\n- Forks: 1\n- Watchers: 6\n- Open issues: 1\n- Primary language: JavaScript\n- L anguages: JavaScript\n- Default branch: master\n- Created: 2015-08-27T22:14:06Z\n- Last push: 2015-09 -01T01:14:37Z\n- Contributors: 2 (top: kriztynna, cgalbiati)\n...\nThe useless-garbage library is the only npm module that is guaranteed to have no redeemable functionality whatsoever.
