Codearia Sieve MCP Server

Parses a web page into the exact format a decision model needs. Dates as dates. Numbers with units. Text in chunks that fit the model's window, each pointing back to where it came from. It runs locally over stdio via the published package.

People who work with content extraction, context engineering and html to markdown and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

before you install - you'll need

TYPESAFE_API_KEY

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add antong87-codearia-sieve -- npx -y codearia-sieve

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "antong87-codearia-sieve": {
      "command": "npx",
      "args": [
        "-y",
        "codearia-sieve"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
