제작자가 쓴 설명(영어 원문)
Use WhatsApp from AI apps through the Kaption extension. OAuth 2.1 relay that cannot read messages.
이 세 가지는 절대 하나의 점수로 합치지 않아요. 의견, 측정, 인기는 서로 다른 것이니까요.
이 서버는 아직 쉬운 말로 된 요약을 쓰지 못했어요. 아래는 레지스트리에서 읽어 온 사실이에요.
쓰고 있는 AI 앱을 고른 다음 설정을 복사하세요.
필요한 것
어떤 앱을 쓰세요?
위에서 앱을 고르세요. 기억해 두었다가 다음부터는 버튼에 “…에 설치”라고 표시해요.
웹, 데스크톱, 모바일의 Claude에서 쓸 수 있어요:
https://mcp.kaptionai.com/mcp터미널에서 이 명령어를 실행하세요
claude mcp add --transport http extension-remote https://mcp.kaptionai.com/mcp프로젝트의 .cursor/mcp.json 또는 ~/.cursor/mcp.json에 붙여 넣으세요
{
"mcpServers": {
"extension-remote": {
"url": "https://mcp.kaptionai.com/mcp"
}
}
}브라우저가 앱을 열지 물어본 다음, 앱이 설정을 보여 주고 확인을 요청해요. 키 값은 비워 두니 직접 입력하세요.
프로젝트의 .vscode/mcp.json에 붙여 넣으세요

"servers": {
"extension-remote": {
"type": "http",
"url": "https://mcp.kaptionai.com/mcp"
}
}
}브라우저가 앱을 열지 물어본 다음, 앱이 설정을 보여 주고 확인을 요청해요. 키 값은 비워 두니 직접 입력하세요.
ChatGPT는 인터넷에 있는 서버에만 연결할 수 있어요:
https://mcp.kaptionai.com/mcp메뉴 이름은 요금제나 시기에 따라 조금 다를 수 있어요.
선택한 앱은 이 기기의 쿠키에만 저장돼요. 계정은 필요 없어요.
이 설정은 제작자의 레지스트리 정보로 만들었어요. README와 다르면 README를 따르세요.
아직 이 서버의 도구 목록을 읽지 않았어요. 엔드포인트는 차례대로 돌아가며 점검해요.
누구나 볼 수 있는 정보를 점검했고, 코드는 읽지 않았어요. 해당하지 않는 항목은 개수에서 뺐어요. · 2026년 11월 7일 점검
레지스트리 이름이 GitHub 계정 Kaption-AI 기준으로 확인되었고, 이 계정이 저장소를 소유하고 있어요

레지스트리에서 이 카테고리의 활성 서버 전체와 비교했어요. 스타는 게시자가 저장소를 소유한 경우에만 세요.
해당하는 기본 점검 1개 중 1개를 통과했어요. 코드는 읽지 않았어요. 키나 토큰을 넣기 전에 서버가 어떤 권한을 요구하는지 확인하고, 꼭 필요한 권한만 있는 키를 쓰세요.
레지스트리에 필수 키가 나와 있지 않아요. 다만 처음 쓸 때 로그인을 요구하는 서버도 있어요.
제작자의 클라우드에서 실행돼요. 설치 없이 인터넷으로 연결하지만, 보내는 내용은 제작자의 서버를 거쳐요.
GitHub 저장소는 마지막으로 – 변경됐고, 최신 버전(1.0.0)은 33일 전 레지스트리에 올라왔어요.
Claude Desktop, Claude Code, Cursor, VS Code처럼 MCP를 지원하는 앱에서 쓸 수 있어요. URL로 연결되기 때문에, 원격 MCP 서버를 지원하는 앱(예: 개발자 모드의 ChatGPT)에서도 쓸 수 있어요.
같은 카테고리에는: Vexa, emailmd, MCP WhatsApp Cloud
같은 카테고리에서 다른 제작자가 만든 서버예요. 스타 순으로 정렬했어요.

Cloud MCP relay for WhatsApp — lets AI assistants (Claude, ChatGPT, Cursor, etc.) interact with your WhatsApp conversations through the Model Context Protocol.
Setup guide: kaptionai.com/mcp — connect WhatsApp to Claude, ChatGPT or Cursor.
Live at: mcp.kaptionai.com (canonical) and mcp-ext.kaptionai.com (backward-compatible alias for existing connections)
The relay cannot read your messages. It forwards MCP tool calls between the AI client and the Kaption browser extension, which processes everything locally in your browser. Its source code is public (BUSL-1.1), so you can verify it yourself.

26 public tools are forwarded to the extension (the relay does not execute them). Reads and writes are separate tools: every read-only tool carries readOnlyHint: true, and the manage_* tools only write. The read tools for reminders, scheduled messages, chat lists and contact notes reach the extension as the matching manage_* call (TOOL_ROUTES in src/tools.ts), so every Kaption version answers them.
| Tool | Kind | Description |
|---|---|---|
query | read | Query conversations, contacts, messages, transcriptions, labels, communities, sessions |
summarize_conversation | write (private cache) | Get or generate a conversation summary |
download_media | read | Download image/video/audio/document from a message |

manage_chat | write | Archive, pin, mute, mark read/unread, set/clear draft |
manage_reminders | write | Create/update/complete/delete personal reminders |
manage_scheduled_messages | write | Schedule, change or cancel messages — from Kaption's number (bot, default) or from your own number on this computer (mode: "local", also to groups) |
manage_lists | write | Create/edit/delete personal chat lists and their chats |
send_message | write | Queue a message from your own number (needs sending from this computer turned on and consent in Kaption) |
create_attachment_upload | write | One-time upload slot for an attachment to send or schedule |

get_api_info is local-only and is deliberately excluded from the cloud surface because it returns private REST connection credentials.
Every deployment is cryptographically signed and recorded in a tamper-evident transparency chain. See SECURITY.md for full details.
GitHub Actions (push to main)
│ ├─ 1. Run tests ├─ 2. Build worker (OpenNext + wrap) ├─ 3. SHA-256 manifest every generated code and asset file ├─ 4. Pre-deploy: Sigstore sign the manifest → Rekor log ├─ 5. Deploy to Cloudflare ├─ 6. Post-deploy: verify hash unchanged, sign attestation → Rekor └─ 7. Append to transparency chain (hash-linked)
Daily heartbeat redeploys (6am UTC) ensure the chain stays active even without code changes.
wrangler deploy locallyAll production deploys go through GitHub Actions. Multiple layers enforce this:
wrangler.jsonc is gitignored; scripts/build-config.mjs renders it from wrangler.template.jsonc and refuses to run unless GITHUB_ACTIONS=true + GITHUB_RUN_ID are set (or KAPTIONAI_LOCAL_DEV=1 for dev).npm run predeploy aborts unless those same CI env vars are present.main is branch-protected: requires a reviewed PR + green test, deploy, and verify checks.To ship a change: open a PR → review + CI green → merge to main → Actions builds, signs (Sigstore), deploys, and appends to the transparency chain. npx wrangler deploy from a laptop will fail at step 1 because there is no wrangler.jsonc to deploy.

JWT_SECRET | Shared JWT signing secret (same as rest-api, schedule, metadata workers) |
PHONE_REF_SECRET | HMAC secret used to derive opaque durable account references from phone numbers |

OPENAI_REVIEW_PASSWORD_SHA256 | Lowercase SHA-256 hex digest of the high-entropy reviewer password |
OPENAI_REVIEW_PHONE | Phone number used as the dedicated review username and to derive the synthetic account's opaque reference |
The three OPENAI_* values are also configured as GitHub Actions repository secrets. Add all three together, then run the manual Test, Build & Deploy workflow. CI writes them to an ephemeral mode-0600 file and passes that file to wrangler deploy --secrets-file, so the review configuration ships in the same signed, attested Worker version as the code. The workflow fails closed if only part of the three-value set is present and deletes the temporary file immediately after deployment. Existing Worker
