# lineai-mcp-server An MCP server that feeds Lineai's software dependency data to your AI assistant, so it can tell what a code change will break. - MCP server · `type=mcp` · Claude Code, Codex, Cursor, GitHub Copilot, Windsurf (Devin Desktop), Cline, Zed, Gemini CLI · ★ 37 - Author: lineai-intelligence - License: MPL-2.0 · policy=link-only · description only; the file stays with the author - Source: https://github.com/lineai-intelligence/lineai-mcp-server - Updated: 2026-10-23 - HTML: https://affpapa.org/en/nevibecode/mcp/lineai-mcp-server ## What it does Eight tools come with the server. Two handle impact: `lineai-method-impact` takes the method you are editing plus an optional `class` filter for ambiguous matches, and `lineai-database-impact` maps code against database entities — a column, table or view. The other six talk to Lineai's graph API: node search, dependency traversal from `seed_node_ids`, shortest-path explanation between two nodes, change-scope validation, owner lookup and a capabilities call. Every tool accepts optional `workspace` and `materialized_view_id` arguments to scope a call. Leave both out and skip `LINEAI_WORKSPACE_NAME`, and the server falls back to the latest materialized view of its default workspace. MCP schema arguments allow snake_case aliases; request bodies to Lineai use camelCase keys. Astral UV is required to run it, so `uv` has to be present before you connect anything. On MacOS `uvx` can fail to launch inside IDEs such as Cursor, and the workaround is cloning the repo and pointing `mcp.json` at `uv` with `--directory` instead of `uvx`. Lineai credentials go into `LINEAI_SERVER_HOST`, `LINEAI_USERNAME`, `LINEAI_PASSWORD` and `LINEAI_WORKSPACE_NAME`; the server cannot authenticate without them. ## Requirements - Needs: Python and uv (commands run via uvx) - Environment variables: `LINEAI_SERVER_HOST`, `LINEAI_USERNAME`, `LINEAI_PASSWORD`, `LINEAI_WORKSPACE_NAME`, `LINEAI_DEBUG_MODE` — keys and tokens: ask the human for the values, never commit them or put them in shared files. ## Install ### Claude Code (native platform) **Platform CLI** ```bash claude mcp add --env LINEAI_SERVER_HOST= --env LINEAI_USERNAME= --env LINEAI_PASSWORD= --env LINEAI_WORKSPACE_NAME= --env LINEAI_DEBUG_MODE= --transport stdio lineai-mcp-server -- uvx lineai-mcp-server ``` Replace <…> with your own values. uvx runs the command named after the package; if the README names another one, use uvx --from lineai-mcp-server ### Codex **Platform CLI** ```bash codex mcp add lineai-mcp-server --env LINEAI_SERVER_HOST= --env LINEAI_USERNAME= --env LINEAI_PASSWORD= --env LINEAI_WORKSPACE_NAME= --env LINEAI_DEBUG_MODE= -- uvx lineai-mcp-server ``` Replace <…> with your own values. uvx runs the command named after the package; if the README names another one, use uvx --from lineai-mcp-server ### Cursor **Config file** File `.cursor/mcp.json`: ```json { "mcpServers": { "lineai-mcp-server": { "command": "uvx", "args": [ "lineai-mcp-server" ], "env": { "LINEAI_SERVER_HOST": "", "LINEAI_USERNAME": "", "LINEAI_PASSWORD": "", "LINEAI_WORKSPACE_NAME": "", "LINEAI_DEBUG_MODE": "" } } } } ``` Replace <…> with your own values. uvx runs the command named after the package; if the README names another one, use uvx --from lineai-mcp-server ### GitHub Copilot **Config file** File `.vscode/mcp.json`: ```json { "servers": { "lineai-mcp-server": { "type": "stdio", "command": "uvx", "args": [ "lineai-mcp-server" ], "env": { "LINEAI_SERVER_HOST": "", "LINEAI_USERNAME": "", "LINEAI_PASSWORD": "", "LINEAI_WORKSPACE_NAME": "", "LINEAI_DEBUG_MODE": "" } } } } ``` Replace <…> with your own values. uvx runs the command named after the package; if the README names another one, use uvx --from lineai-mcp-server ### Gemini CLI **Platform CLI** ```bash gemini mcp add -e LINEAI_SERVER_HOST= -e LINEAI_USERNAME= -e LINEAI_PASSWORD= -e LINEAI_WORKSPACE_NAME= -e LINEAI_DEBUG_MODE= lineai-mcp-server uvx lineai-mcp-server ``` Replace <…> with your own values. uvx runs the command named after the package; if the README names another one, use uvx --from lineai-mcp-server ## When to use it - find which call sites break after editing a method - trace how a code change touches database columns and tables - locate the owner of a node in the dependency graph - explain the path between two nodes before a refactor - assess risk for a proposed change from seed nodes ## Example prompts - Assess the impact of changing the `calculateTotal` method in `OrderService` - Which tables and columns does this change touch? - Explain the shortest path between `from_node_id` and `to_node_id` in the dependency graph ## Similar - [REA](https://affpapa.org/en/nevibecode/mcp/rea.md) — MCP server · ★ 386989 - [GitHub](https://affpapa.org/en/nevibecode/mcp/github.md) — MCP server · ★ 33918 - [Netdata](https://affpapa.org/en/nevibecode/mcp/netdata.md) — MCP server · ★ 81115 - [browser-use](https://affpapa.org/en/nevibecode/mcp/browser-use.md) — MCP server · ★ 119160 - [Codebase Memory](https://affpapa.org/en/nevibecode/mcp/codebase-memory.md) — MCP server · ★ 47392 - [mcp-server](https://affpapa.org/en/nevibecode/mcp/mcp-server.md) — MCP server · ★ 43872 --- NeVibeCode on affpapa.org.
