MCP connector plugin that extends Claude Code with FN2 tools

Free

It adds a set of FN2 utilities to Claude Code, enabling developers to run code snippets, manage dependencies, and invoke external APIs directly from the Claude interface. The plugin installs via the MCP connector and appears as a new toolbar within Claude's editor, so users can access functions without leaving the chat window. It also logs each execution to a searchable history panel, allowing users to revisit past runs and compare outputs. Key capabilities include an isolated execution sandbox that supports Python, JavaScript, and Bash; a lightweight dependency manager that fetches packages from PyPI or npm on demand; an API request builder that formats HTTP calls and displays responses inline; Git integration that commits generated scripts to a repository with a single click; real‑time output preview that streams console logs as code runs; and customizable keyboard shortcuts for frequent actions. The sandbox enforces resource limits, preventing runaway processes and ensuring the host environment remains stable. The tool targets software engineers, DevOps specialists, and technical writers who need rapid prototyping inside Claude. It is useful for testing algorithm ideas, generating deployment scripts, or documenting API usage without switching tools. FN2 for Claude Code is offered completely free, with no usage caps or paid tiers, making it a cost‑effective alternative to separate IDE extensions. Compared with generic code assistants, it provides direct execution and version control hooks, reducing context switches. Setup takes under five minutes: install the MCP connector, authorize repository access, and start issuing commands from Claude's prompt.
