build-mcp-server — Skills — getagentictools

What it does

Just me / my team, on our machines → Local stdio is acceptable (easiest to prototype)

Anyone who installs it → Remote HTTP (strongly preferred) or MCPB (if it must be local)

Users of Claude desktop who want UI widgets → MCP app (remote or MCPB)

Under ~15 actions → one tool per action

Dozens to hundreds of actions (e.g. wrapping a large API surface) → search + execute pattern

Neither → plain tool returning text/JSON.

None / API key → straightforward

Requirements & configuration

4. Does a tool need mid-call user input or rich display?

Rich/visual UI (charts, custom pickers with search, live dashboards) → MCP app widgets — iframe-based, needs @modelcontextprotocol/ext-apps. See build-mcp-app skill.

None / API key → straightforward

OAuth 2.0 → you'll need a remote server with CIMD (preferred) or DCR support; see references/auth.md

OAuth flows work properly (the server can handle redirects, DCR, token storage)

build-mcp-server FAQ

What does the build-mcp-server skill do?

This skill should be used when the user asks to "build an MCP server", "create an MCP", "make an MCP integration", "wrap an API for Claude", "expose tools to Claude", "make an MCP app", or discusses building something with the Model Context Protocol. It is the entry point for MCP server development — it interrogates the user about their use case, determines the right deployment model (remote HTTP, MCPB, local stdio), picks a tool-design pattern, and hands off to specialized skills.
