# AssistAI — Eclipse IDE as an MCP Server

> An Eclipse plugin exposing your IDE as MCP endpoints for read/edit/build/test/debug via Eclipse APIs; verified 148★, pushed 2026-05-14.

## Install

Merge the JSON below into your `.mcp.json`:

## Quick Use

```bash
# Install via Eclipse Update Site (README):
# https://gradusnikov.github.io/eclipse-chatgpt-plugin/
# Then enable HTTP MCP Server in Preferences (port 8124).
npx -y mcp-remote http://localhost:8124/mcp/eclipse-ide --allow-http --header "Authorization: Bearer YOUR_TOKEN"
```

## Intro

An Eclipse plugin exposing your IDE as MCP endpoints for read/edit/build/test/debug via Eclipse APIs; verified 148★, pushed 2026-05-14.

**Best for:** Java teams who want agent edits to stay in sync with Eclipse (JDT, refactoring, local history)

**Works with:** Eclipse IDE; exposes HTTP MCP endpoints on localhost:8124 and can be used via `npx mcp-remote` (README)

**Setup time:** 15-35 minutes

### Key facts (verified)

- GitHub: 148 stars · 70 forks · pushed 2026-05-14.
- License: MIT · owner avatar + repo URL verified via GitHub API.
- README-backed entrypoint: `npx -y mcp-remote http://localhost:8124/mcp/eclipse-ide --allow-http`.

## Main

- Use MCP-through-Eclipse to avoid stale buffers: README explains reads reflect editor buffers and writes go through JDT/refactoring engines.

- Split permissions by endpoint: IDE/coder/runner/git/context endpoints let you only enable what you need and reduce token overhead.

- Generate and store the auth token: README shows `Authorization: Bearer YOUR_TOKEN` headers for clients.

- Treat ignore rules as a safety layer: README mentions `.gitignore`-style patterns to prevent sensitive files from being exposed.

### Source-backed notes

- README lists default endpoints under `http://localhost:8124/mcp/...` including eclipse-ide, eclipse-coder, eclipse-runner, eclipse-context, and eclipse-git.
- README provides a Claude Code config example using `npx -y mcp-remote ... --header "Authorization: Bearer YOUR_TOKEN"`.
- README installation section includes an Eclipse Update Site URL: `https://gradusnikov.github.io/eclipse-chatgpt-plugin/`.

### FAQ

- **Do agents see unsaved editor changes?**: README says reads reflect the editor buffer, not only on-disk files.
- **Can I connect from Codex/other MCP clients?**: Yes — README notes any Streamable HTTP MCP client can connect using the endpoint URL + bearer token.
- **How do I install it?**: Use Eclipse Marketplace or the Update Site URL in README, then enable the HTTP MCP server in Preferences.

## Intro

AssistAI 是 Eclipse 插件：把 IDE 暴露为多个 MCP 端点，让外部 agent 通过 Eclipse API 读写/构建/测试/调试，避免编辑器不同步；已验证 148★，更新于 2026-05-14。

**Best for:** 希望 agent 改代码时仍保持 Eclipse/JDT 同步（重构/增量编译/本地历史）的 Java 团队

**Works with:** 需要 Eclipse IDE；默认 `localhost:8124` 暴露 HTTP MCP 端点，可用 `npx mcp-remote` 连接（README）

**Setup time:** 15-35 minutes

### Key facts (verified)

- GitHub：148 stars · 70 forks；最近更新 2026-05-14。
- 许可证：MIT；作者头像与仓库链接均已通过 GitHub API 复核。
- README 中可对照的入口命令：`npx -y mcp-remote http://localhost:8124/mcp/eclipse-ide --allow-http`。

## Main

- 通过 Eclipse 走 MCP 防止不同步：README 解释读取会反映 editor buffer，写入走 JDT/重构引擎。

- 按端点拆权限：IDE/coder/runner/git/context 多端点结构可只开需要的能力并降低 token 噪音。

- 生成并保存 token：README 要求客户端使用 `Authorization: Bearer YOUR_TOKEN`。

- 把忽略规则当安全层：README 提到使用类似 `.gitignore` 的规则避免敏感文件被暴露。

### Source-backed notes

- README 列出默认端点：`http://localhost:8124/mcp/...`（eclipse-ide/coder/runner/context/git 等）。
- README 给出 Claude Code 配置：通过 `npx -y mcp-remote ... --header "Authorization: Bearer YOUR_TOKEN"` 连接。
- README 安装章节提供 Update Site：`https://gradusnikov.github.io/eclipse-chatgpt-plugin/`。

### FAQ

- **未保存的编辑内容能读到吗？**：README 表示读取反映 editor buffer，而不只是磁盘文件。
- **Codex/其他 MCP 客户端能连吗？**：能；README 说明支持 Streamable HTTP 的 MCP 客户端可用 URL + bearer token 直连。
- **怎么安装？**：按 README 使用 Eclipse Marketplace 或 Update Site 安装，然后在 Preferences 中启用 HTTP MCP server。
