    You say

    Search for a template that parses emails and sends a Slack notification, then show me the parameters for the Slack node v2.

    Your agent does

    Found template: 'Email to Slack Parser' (ID: 1042). Slack node (v2) requires: 'Authentication' (Service Account/Integration Token), 'Resource' (Message), 'Operation' (Post), and 'Channel' (ID or name). Connection confirmed.

    About this skill

    The problem

    Building n8n workflows manually is time-consuming. You waste hours searching for node parameters, browsing templates, and debugging connection errors or invalid expressions.

    What it does

    • Searches over 2,400 nodes and 2,300 templates to find the right building blocks for any task.
    • Creates, updates, and deploys workflows directly to your n8n instance via MCP tools.
    • Uses token-efficient diff operations for editing, reducing LLM costs by 80 to 90 percent.
    • Validates node configurations and workflow connections before deployment to prevent runtime failures.
    • Triggers and tests workflows, manages executions, and performs security audits of your n8n instance.

    Frameworks & tools

    Works with n8n, Docker, and Node.js. Compatible with MCP-enabled clients like Claude Code and Cursor.

    Why this beats prompting it yourself

    A standard LLM lacks real-time knowledge of the latest n8n node schemas and community templates. This skill provides a structured bridge to the n8n API, ensuring the agent uses valid syntax, correct node versions, and secure deployment practices instead of guessing.

    Use cases

    • Build lead enrichment pipelines that connect webhooks, HTTP calls, and Google Sheets.
    • Audit n8n instances for security vulnerabilities and connectivity issues.
    • Iteratively update existing complex workflows using precise diff operations.
    • Search for and deploy verified community templates to solve specific automation tasks.

    Known limitations

    Requires an existing n8n instance and API key for management features. Claude Desktop requires specific stdio configuration to avoid JSON parsing errors.

    How to install
