Builds MCP servers: OpenAPI-to-tool conversion, tool and schema linting, TypeScript or Python scaffolds, transports. Use when exposing an API to AI agents, building a tool server, or reviewing MCP tool definitions.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# MCP Server Builder The agent designs and ships MCP (Model Context Protocol) servers whose tools an agent picks correctly and calls safely: verb_noun names, descriptions that say when to use the tool and what it returns, typed inputs, paginated lists and gated destructive actions. Schema quality is the main lever: the model chooses tools from names and descriptions alone. ## When to Use - Exposing an internal REST API to Claude, Cursor or another MCP client. - Converting an OpenAPI spec into MCP tools, then fixing what the conversion gets wrong. - Replacing brittle browser automation with typed tool interfaces. - Reviewing an existing server's tool definitions before release. ## Clarify First Before building the server, settle the inputs below. When one is missing or vague and would change the result, ask about it; when it wouldn't, use a sensible default and say which one you used. - **Source contract:** an OpenAPI spec, an existing API, or tools designed from scratch. - **Language:** TypeScript (`@modelcontextprotocol/sdk`) or Python (`mcp`). - **Transport:** stdio for local tools, Streamable HTTP for remote or shared servers (HTTP+SSE only for legacy clients). …

How to install
mdr add borghei/claude-skills/mcp-server-builder@sha256:59e4e1a7a4b4c893The line at the top of this page pins the label v1.3.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
