Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@firmafast/tasker-mcp

v0.1.1

Published

MCP server for the Tasker kanban API — lets LLM agents read and operate Tasker boards

Readme

Tasker MCP Server

Servidor MCP (Model Context Protocol) que expone la REST API de Tasker como tools para agentes LLM (opencode, Claude, Cursor, etc.).

Publicado en npm como @firmafast/tasker-mcp — se instala con npx, sin clonar el repo.

Requisitos

  • Node.js >= 20
  • Un Tasker corriendo y accesible por HTTP
  • Una API key: la master key (MASTER_API_KEY) o una API key de tablero (prefijo tskr_, visible en el snapshot del tablero)

Configuración

Variables de entorno:

| Variable | Default | Descripción | |---|---|---| | TASKER_API_URL | http://localhost:3000 | Base URL del Tasker (sin trailing slash) | | TASKER_API_KEY | — | Master key o API key de tablero (obligatoria) |

Instalación

opencode

Agregá al opencode.json global (~/.config/opencode/opencode.json) o del proyecto:

{
  "mcp": {
    "tasker": {
      "type": "local",
      "command": ["npx", "-y", "@firmafast/tasker-mcp"],
      "enabled": true,
      "environment": {
        "TASKER_API_URL": "https://tasker.tudominio.com",
        "TASKER_API_KEY": "tskr_..."
      }
    }
  }
}

Nota: en opencode la config de env de un MCP local se declara con environment (no env). Verificá la sintaxis de tu versión.

Claude Desktop / Cursor / otros clientes MCP

{
  "mcpServers": {
    "tasker": {
      "command": "npx",
      "args": ["-y", "@firmafast/tasker-mcp"],
      "env": {
        "TASKER_API_URL": "https://tasker.tudominio.com",
        "TASKER_API_KEY": "tskr_..."
      }
    }
  }
}

Desarrollo (desde el repo)

cd mcp
npm install
npm run build   # -> dist/index.js
npm run dev     # corre con tsx, sin build

Publicar una versión nueva

cd mcp
npm version patch   # o minor / major
npm publish         # corre prepublishOnly -> build

Tools

| Tool | Descripción | |---|---| | list_boards | Lista tableros visibles para la key | | get_board | Snapshot completo: columnas + campos custom + tarjetas | | list_columns / create_column | Columnas de un tablero | | list_cards / get_card | Tarjetas | | create_card | Crea tarjeta (columna por id, por nombre, o primera) | | update_card | Actualiza tarjeta: título, contenido, mover de columna, labels, due_date, assignees, external_id, custom_fields | | list_comments / add_comment | Comentarios de una tarjeta |

Desarrollo

npm run dev   # corre con tsx, sin build

Probar el handshake por stdio:

printf '%s\n' \
  '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"t","version":"1"}}}' \
  '{"jsonrpc":"2.0","method":"notifications/initialized"}' \
  '{"jsonrpc":"2.0","id":2,"method":"tools/list"}' \
  | TASKER_API_KEY=test node dist/index.js

Notas

  • La API de Tasker responde CORS *, pero no importa: el MCP corre server-side por stdio, no en el browser.
  • Con una API key de tablero solo se ve/opera ese tablero; con la master key, todos. La master key además permite creator_id y author custom en comentarios.
  • Los errores de la API (401/403/404/400) se devuelven como texto legible en la respuesta de la tool, no como crash.
