This MCP server provides hash-verified file editing and codebase inspection tools for AI coding agents, with revision-aware edits that reduce stale-context mistakes and preserve file formatting. It also installs hooks that redirect project-scoped file access, block dangerous shell commands, and can add optional graph-based hints when a project has codegraph data.
From the registry: Hash-verified file editing MCP server with token efficiency hook for AI coding agents.
Install & configure
Prerequisites
- requiredInstall Node.js 20.19.0 or newerNode.js version 20.19.0 or later is required to run the MCP server.
- requiredInstall the hex-line-mcp package globallyInstall the MCP server package so the `hex-line-mcp` executable is available on your system.

Install in your client
Paste into the AI you're chatting with — it will figure out the rest
Please install the `hex-line-mcp` MCP server into my current AI client (that's you).
Required prerequisites (do these first if not already done):
- **Install Node.js 20.19.0 or newer** — Node.js version 20.19.0 or later is required to run the MCP server.
- **Install the hex-line-mcp package globally** — Install the MCP server package so the `hex-line-mcp` executable is available on your system. Run: `npm i -g @levnikolaevich/hex-line-mcp` (https://www.npmjs.com/package/@levnikolaevich/hex-line-mcp)
Canonical MCP server config (stdio transport):
- command: `hex-line-mcp`
- args: []
Note: This is a stdio MCP server. The README's Claude-specific `claude mcp add` example wraps the canonical command `hex-line-mcp`. No environment variables are documented as required. Optional Claude-specific hooks and output style are auto-installed on server startup after global install, but they are not part of the MCP server command/config. ripgrep is bundled; no separate ripgrep install is needed. Optional graph enrichment may work if a project has `.hex-skills/codegraph/index.db`; `better-sqlite3` is optional and not required for normal operation.
Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.Note: This is a stdio MCP server. The README's Claude-specific `claude mcp add` example wraps the canonical command `hex-line-mcp`.
