MCP Agent Skills

Agent Skills are portable instruction sets (SKILL.md) that provide AI coding assistants with specialized domain knowledge for designing and implementing MCP servers.

Core Development Skills

  • build-mcp-server: The primary entry point. It interrogates the use case (API vs. local, user base size, auth needs) to recommend a deployment model.
  • build-mcp-app: Used when interactive UI widgets (forms, charts, dashboards) are needed within the chat interface.
  • build-mcpb: Packages local servers with their runtimes as MCP Bundles, allowing users to install them without pre-existing environments (e.g., without needing Node or python).

Core Operational Skills

  • verbalized-sample-skill: An operational protocol for counteracting mode collapse. It forces the model to surface the long tail of its response distribution through structured verbalized-sampling.

Recommended Deployment Paths

Based on the discovery phase, skills guide agents toward one of four architectures:

  1. Remote (HTTP/SSE): Default for cloud APIs. Supports easy OAuth flows and global access.
  2. MCP Apps: Extends servers with rich, interactive chat widgets.
  3. MCP Bundles (MCPB): Ideal for servers that interact with the local filesystem or desktop apps.
  4. Local (Stdio): Best for prototyping and private scripts.

Usage in Coding Assistants

Ask your agent to "Help me build an MCP server." If the agent has the mcp-server-dev skill installed, it will automatically follow the discovery-design-scaffold workflow to ensure the resulting server is protocol-compliant.
