Kubb MCP Server
Official local Model Context Protocol server shipped inside the `kubb` CLI (npm package `kubb`, 5.16.0 at time of writing) and started with `kubb mcp`. It uses the stdio transport, so an MCP client launches it as a local process in the project folder; it is not a hosted service. The docs mark it "under active development ... expect breaking changes". It is also registered by the Kubb Claude Code plugin (tools/claude/.mcp.json in kubb-labs/kubb). Kubb Studio (kubb.studio) itself publishes no hosted MCP endpoint; this is distinct from @kubb/plugin-mcp, which GENERATES MCP servers from a customer's OpenAPI spec.
One-click install for Cursor, VS Code, Claude, and 20+ other MCP clients, powered by API Commons MCP Install — visit install.apicommons.org for more information.

Tools
generate— Runs the Kubb pipeline. On success returns the file count plus warnings and diagnostics; on failure returns each diagnostic with its code, fix and docs link. A config exporting an array runs its first entry.validate— Validates an OpenAPI or Swagger document with the bundled OpenAPI adapter.init— Writes a kubb.config.ts with an empty plugins array in the working directory without prompts. Does not install packages; its reply tells the agent to run `kubb add--yes` per plugin. Fails when kubb.config.ts already exists.
About MCP
The Model Context Protocol (MCP) is an open protocol Anthropic introduced for connecting LLM-based agents to external tools and data sources. Providers publish MCP servers that expose their API surface as structured, discoverable tools — an MCP-compatible client (Claude Desktop, Cursor, Cline, Continue, etc.) can connect to the server and call its tools without any per-provider integration code.

Every MCP server here is available over the APIs.io API and to AI agents over MCP.
