MCP Server Overview

KillerSkills exposes an MCP (Model Context Protocol) server endpoint for native tool integration with AI agents. This allows AI systems to search and retrieve skills and personas directly from the KillerSkills marketplace.

What is MCP?

The Model Context Protocol (MCP) is a standardized protocol that lets AI agents use external services as tool providers. When you connect KillerSkills via MCP, AI agents can:

  • Search the skills marketplace by query, category, or runtime
  • Retrieve full skill content including markdown instructions
  • Search the personas marketplace
  • Get complete persona definitions with bundled skills

Protocol Details

  • Protocol: MCP 2024-11-05 (JSON-RPC over HTTP POST)
  • Endpoint: POST https://killerskills.ai/api/mcp
  • Authentication: None required (public data only)
  • Content-Type: application/json

Available Tools

The KillerSkills MCP server provides four tools:

  • search_skills — Search the skills marketplace
  • get_skill — Get full skill content by slug
  • search_personas — Search the personas marketplace
  • get_persona — Get full persona content by slug

MCP vs REST API

Use MCP when: You're building with AI agents that natively support MCP tool servers (Claude Desktop, Claude Code, Cursor, etc.). MCP provides a standardized interface that AI systems can automatically discover and use.

Use the REST API when: You're building programmatic integrations, web applications, or services that don't use MCP-compatible AI agents.

Getting Started

To connect KillerSkills to your AI agent:

  1. Review the connection guide for your specific tool
  2. Explore the tools reference to understand available capabilities
  3. Start using KillerSkills as a tool provider in your AI workflows
