概览

AI 生成的概览

Hekkova 是一个远程 MCP 服务器,让 AI 助手把照片、视频、音频和文字铸造为 Polygon 区块链上永久保存、可加密的 NFT 记录。

可以做什么
  • 把媒体或文字铸造为 Polygon 上的永久时刻,支持 IPFS 固定存储与可选加密
  • 抓取公开网址(如帖子或网页)并直接铸造,自动提取标题与图片
  • 列出、筛选并查看已铸造时刻的区块 ID、CID、交易哈希、隐私阶段与标签
  • 更改时刻的隐私阶段,并将全部时刻导出为 JSON 或 CSV,附 24 小时下载链接
  • 查询剩余铸造额度、套餐与阶段切换余额,以及账户身份与钱包地址
适用场景
适合希望让助手把媒体或文字归档为带隐私分级的、可验证且不可篡改的链上记录,或跨会话保留可导出的永久记忆的场景。它面向已拥有 Hekkova 账户和额度的用户,而非通用存储用途。
运行要求
通过 streamable HTTP 连接 mcp.hekkova.com 远程端点,认证方式为 OAuth(必需)。需要 Hekkova 账户与 API 密钥;铸造会消耗与套餐绑定的额度,付费套餐可提高速率限制。
安装前请注意
铸造会写入永久性的公链数据并消耗额度,更改隐私阶段需 1 至 2 个额度。媒体会被固定到 IPFS 与 Filecoin 并经 Lit Protocol 加密,铸造后可能难以撤回。API 密钥属于持有者凭证,应妥善保管,泄露后及时吊销。导出会生成 24 小时有效的下载链接。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Hekkova,将其添加到工作区。
  2. 连接 所需的 凭据。它们会被私密存储,绝不会在公开页面上展示。
  3. 为需要使用其工具的对话启用该服务。

Web executable,通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体,或 SourceWeft 对话中。智能体会读取该服务器的安装指南,先向你展示发布者、端点和登录方式,经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/com.hekkova%2Fmcp/install.md,并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前,先告诉我它的发布者、端点和登录方式,等我确认。不要把 API 密钥写进命令或我会提交的文件;问我密钥应从哪里获取。

其他 MCP 客户端

把它添加到你客户端的 mcpServers 配置中。 客户端会在首次连接时完成 OAuth 登录。

README

Hekkova MCP Server

The permanent memory layer for AI agents. Connect any MCP-compatible AI (Claude, ChatGPT, Gemini, Cursor, custom agents) and mint moments — photos, videos, audio, text — permanently to the Polygon blockchain with IPFS + Filecoin storage, Lit Protocol encryption, and privacy tiers that let you control who sees what.


Quick Start

bash
# 1. Install dependenciesnpm install
# 2. Copy and configure environment variablescp .env.example .env# Edit .env with your Supabase, Thirdweb, Pinata, and Stripe credentials
# 3. Seed the local test account and API keynpm run seed
# 4. Start the development servernpm run dev# → Server running at http://localhost:3000/mcp

Connect with Claude Desktop

Add this to your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

json
{  "mcpServers": {    "hekkova": {      "type": "url",      "url": "http://localhost:3000/mcp",      "headers": {        "Authorization": "Bearer hk_test_local_dev_key_12345678"      }    }  }}

For production, replace the URL and API key:

json
{  "mcpServers": {    "hekkova": {      "type": "url",      "url": "https://mcp.hekkova.com/mcp",      "headers": {        "Authorization": "Bearer hk_live_YOUR_API_KEY"      }    }  }}

Tool Reference

ToolDescription
mint_momentMint media (photo, video, audio, text) permanently to Polygon. Encrypts based on phase, pins to IPFS, mints ERC-721 NFT. Returns a Block ID.
mint_from_urlFetch a public URL (tweet, Instagram post, image, web page) and mint it. Extracts og:title and og:image automatically.
list_momentsPaginated list of all minted moments. Filterable by phase, category, or search query.
get_momentFull details for a single moment by Block ID: CIDs, transaction hash, phase, tags, and more.
update_phaseChange a moment's privacy phase. Costs 1 credit (text/image) or 2 credits (video). Legacy Plan includes 10 free Phase Shifts/month.
export_momentsExport all moments as JSON or CSV. Returns a 24-hour download URL with all Block IDs and IPFS CIDs.
get_balanceCheck remaining mint credits, current plan (free / arc_builder / legacy), and phase shift balance.
get_accountAccount identity: Light ID, display name, wallet address, default phase, and legacy plan status.

Running Tests

bash
# Make sure the server is running in another terminalnpm run dev
# Run the test clientnpm run test-client

Deployment

Vercel (Serverless)

bash
npm install -g vercelvercel

Add a vercel.json:

json
{  "builds": [{ "src": "src/server.ts", "use": "@vercel/node" }],  "routes": [{ "src": "/(.*)", "dest": "src/server.ts" }]}

Set all environment variables in the Vercel dashboard under Project → Settings → Environment Variables.

Railway

bash
npm install -g @railway/clirailway loginrailway initrailway up

Set environment variables in the Railway dashboard. Railway will auto-detect the npm start script.

Fly.io

bash
npm install -g flyctlfly auth loginfly launch

Fly will generate a fly.toml. Set secrets with:

bash
fly secrets set SUPABASE_URL=... SUPABASE_SERVICE_KEY=... THIRDWEB_SECRET_KEY=...fly deploy
