Free MCP Core

npm

Library-form fork of freee/freee-mcp. Exposes the MCP server framework, API client, OpenAPI schema loader, and skill resources as npm library exports for use as a dependency, while preserving upstream CLI binary compatibility.

Works with: Claude Code, Cursor, Claude Desktop, Codex CLI, Gemini CLI, Cline, Windsurf, VS Code (installable)
installable: each client documents how to load an MCP server of this type — that is the client's promise, not a claim verified against this capability
