# Agents that work with Graph Indexer

> Graph Indexer works with 10 AI coding agents over MCP, including Claude Code, Cursor, Copilot and Codex. npx graph-indexer init writes each agent's config.

Graph Indexer is a local MCP server that works with ten AI coding agents: Claude Code, Cursor, VS Code Copilot, Codex, Gemini CLI, OpenCode, Kilo Code, Junie, Zed and Devin. Run `npx graph-indexer init` in your repository and it writes the project-level MCP configuration for each agent it detects, so the agent gets the same eight read-only tools for exact references, call graphs and change impact.

## Which agents does Graph Indexer support?

The table lists each agent, the file `npx graph-indexer init` writes for it, and the page with the exact configuration. Agents marked "printed" have no project-level config file that `init` can edit, so it prints the entry to paste instead.

| Agent | File written by `init` | Guide |
|---|---|---|
| Claude Code | `.mcp.json` (plus `.claude/agents/code-structure.md`) | [Claude Code](/agents/claude-code/) |
| Cursor | `.cursor/mcp.json` | [Cursor](/agents/cursor/) |
| VS Code Copilot | `.vscode/mcp.json` | [VS Code Copilot](/agents/vscode-copilot/) |
| Codex | printed TOML for `~/.codex/config.toml` | [Codex](/agents/codex/) |
| Gemini CLI | `.gemini/settings.json` | [Gemini CLI](/agents/gemini-cli/) |
| OpenCode | `opencode.json` | [OpenCode](/agents/opencode/) |
| Kilo Code | `opencode.json` (or an existing `kilo.json`) | [Kilo Code](/agents/kilo-code/) |
| Junie | `.junie/mcp/mcp.json` | [Junie](/agents/junie/) |
| Zed | `.zed/settings.json` | [Zed](/agents/zed/) |
| Devin | printed server entry for Devin's MCP settings | [Devin](/agents/devin/) |

## What do all the agents get in common?

Every agent talks to the same stdio server and sees the same tools: `read_code`, `search_text`, `search_code`, `find_references`, `call_graph`, `change_impact`, `check_changes` and `outline`. The [tools reference](/tools/) lists their parameters. Graph Indexer itself makes no network calls and sends no telemetry; the agent still sends what it reads to its model provider.

`init` also adds a short managed block to `CLAUDE.md` or `AGENTS.md` that tells the agent when to use `find_references`, `call_graph`, `change_impact` and `check_changes`. It merges into existing config files and never overwrites other MCP servers.

## What if my agent is not on the list?

Any MCP client can run Graph Indexer over stdio with the command `npx -y graph-indexer@3 serve --repo /path/to/repo`. `init` prints the same instruction for Claude Desktop, JetBrains AI Assistant and Cline. See [Install Graph Indexer](/install/) for the manual configuration and the Node.js 22.5+ requirement.

## Which agent was the benchmark run on?

The agent benchmarks were run with Claude Code, so the cost and time figures on [the benchmarks page](/benchmarks/) describe that agent. The reference-accuracy numbers measure the tools themselves and do not depend on the agent. Results for other agents may differ, and Graph Indexer does not publish measurements for them.
