概览

AI 生成的概览

LLMKit 的远程 MCP 服务器，基于 RapidAPI 提供 token 计数、RAG 分块、截断、HTML 转 Markdown 和 JSON 修复。

可以做什么
  • 统计文本的 token 数量
  • 把长文本切分为适合 RAG 检索的片段
  • 按 token 或长度上限截断文本
  • 将 HTML 转换为 Markdown
  • 修复格式错误的 JSON 输出
  • 工具由该 API 的路由自动生成，具体工具列表需连接后查看
适用场景
适合在构建或调试 LLM 与 RAG 流程时使用，让助手直接统计 token 用量、准备分块、裁剪提示词、清理 HTML 或修复损坏的 JSON，而无需自己写辅助代码。
运行要求
远程 Streamable HTTP 端点，无需本地包或运行时。需要 RapidAPI 账号并订阅 LLMKit（提供免费套餐），每次请求需携带 X-RapidAPI-Key 与 X-RapidAPI-Host 请求头，并能访问 RapidAPI 主机。
安装前请注意
X-RapidAPI-Key 是敏感密钥，以请求头形式发送，请勿写入共享配置或日志。发送的文本会由第三方 RapidAPI 服务处理。超出免费额度后可能按量计费。

安装

在 SourceWeft 中

  1. 打开 控制台中的 LLMKit，将其添加到工作区。
  2. 连接 Custom headers 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/io.github.OlsOls4%2Fllmkit/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。

README

Developer utility APIs + remote MCP servers

Thirteen small, focused REST APIs for everyday developer jobs: validating emails, phones and IBANs, IP geolocation, PDFs, images, QR codes, fraud scoring, token counting and more. Each one is its own product on RapidAPI with a free plan, full OpenAPI docs, and a built-in remote MCP server so AI agents (Claude, Cursor, VS Code, n8n, LangChain) can call it as tools.

  • Free tier on every API: subscribe on RapidAPI, copy your key, call it.
  • MCP built in: every API exposes Streamable HTTP MCP at https://<host>.p.rapidapi.com/mcp, and each is listed in the official MCP Registry as io.github.OlsOls4/<kit>.
  • No heavy dependencies on your side: plain HTTPS + JSON from any language or no-code tool.

Also available (newer):

  • CurrencyKit: ECB euro reference exchange rates: latest, historical, time series and currency conversion. RapidAPI · MCP https://currencykit-ecb-exchange-rates-currency-converter.p.rapidapi.com/mcp
  • VATKit: Live EU VAT number checks via VIES with company name/address, VAT formats and EU VAT rates. RapidAPI · MCP https://vatkit-eu-vat-number-check-vies-vat-rates.p.rapidapi.com/mcp

Quickstart (REST)

bash
curl -G "https://calkit-public-holidays-business-days-timezones.p.rapidapi.com/business-days/add" \  -d date=2026-12-23 -d days=5 -d country=GB -d subdiv=ENG \  -H "X-RapidAPI-Key: YOUR_RAPIDAPI_KEY" \  -H "X-RapidAPI-Host: calkit-public-holidays-business-days-timezones.p.rapidapi.com"

Swap the host for any API in the table. Every request goes through RapidAPI with X-RapidAPI-Key and X-RapidAPI-Host.

Quickstart (MCP)

Add any API as a remote MCP server in a client that supports Streamable HTTP with custom headers, for example:

json
{  "mcpServers": {    "calkit": {      "type": "http",      "url": "https://calkit-public-holidays-business-days-timezones.p.rapidapi.com/mcp",      "headers": {        "X-RapidAPI-Key": "YOUR_RAPIDAPI_KEY",        "X-RapidAPI-Host": "calkit-public-holidays-business-days-timezones.p.rapidapi.com"      }    }  }}

The server answers tools/list with that API's endpoints as tools.

What's in this repo

  • main.py and one folder per API (webkit, domainkit, qrkit, ...): the FastAPI service behind all listings.
  • mcpserver.py: the MCP layer that turns each API's routes into tools.
  • openapi/: OpenAPI specs for each API.
  • mcp-registry/: server.json files published to the official MCP Registry.
