Editor MCP MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. A Python-based text editor server built with FastMCP that provides powerful tools for file operations. This server enables reading, editing, and managing text files through a standardized API with a unique multi-step approach that.
Once Editor MCP is connected, these are the calls the assistant has available:
Privacy — Everything is stored locally on your machinePrerequisites — The editor-mcp requires: - Python 3.7+ - FastMCP package - black (for Python code formatting checks) - Babel (for JavaScript/JSX syntax checks ifYou will need 6 environment variables: MAX_SELECT_LINES, ENABLE_JS_SYNTAX_CHECK, FAIL_ON_PYTHON_SYNTAX_ERROR, FAIL_ON_JS_SYNTAX_ERROR, PROTECTED_PATHS, STATS_DB_PATH. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
The editor-mcp requires: - Python 3.7+ - FastMCP package - black (for Python code formatting checks) - Babel (for JavaScript/JSX syntax checks if working with those files) Install development dependencies: ```bash
babel on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Editor MCP's toolset — Privacy, Prerequisites — is a fair guide to whether it matches your workflow. It is maintained by danielpodrazka; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
