## Intro

Mistral's Le Chat ships a connector ecosystem — pre-validated tool definitions for Slack, Notion, Google Drive, Linear, Figma, GitHub. Each connector is a typed contract: scopes, capabilities, error modes. The same connector schema can be exposed as an MCP server, letting Claude Code / Cursor / Codex CLI call Le Chat connectors directly. Best for: agents that need read+write access to enterprise SaaS without writing per-tool MCP code. Works with: Le Chat (native), Claude Code / Cursor / any MCP host (via le-chat-mcp). Setup time: 5 minutes (Mistral account + connector OAuth).

### What's in the connector library

| Connector | Reads | Writes |
|---|---|---|
| Slack | channels, messages, users | post message, react |
| Notion | pages, databases | create/update pages, query DB |
| Google Drive | files, folders, content | upload, comment |
| Linear | issues, projects, cycles | create/update issues |
| Figma | files, frames, components | comment, version |
| GitHub | repos, PRs, issues | comment, label |

### Use connectors inside Le Chat

```bash
# In Le Chat web UI, click Connectors → enable Slack/Notion/etc → OAuth in
# Then a normal prompt:
"Find every Linear issue tagged 'urgent' assigned to me, summarize, and post to #engineering on Slack"
```

Le Chat plans the calls, requests approval, and executes.

### Use Le Chat connectors from Claude Code

Add to your MCP config:

```json
{
  "mcpServers": {
    "lechat-connectors": {
      "command": "npx",
      "args": ["-y", "le-chat-mcp"],
      "env": {
        "LECHAT_API_KEY": "your-key",
        "LECHAT_CONNECTORS": "slack,notion,linear,gdrive"
      }
    }
  }
}
```

Now Claude Code can call:
- `lechat_slack_search`
- `lechat_notion_query_database`
- `lechat_linear_create_issue`
- `lechat_gdrive_upload`
- ...all with Le Chat's pre-validated schemas.

### Build a custom connector

```yaml
# my-connector.yaml — register with Mistral via API
connector:
  id: my-internal-crm
  name: Acme CRM
  oauth:
    client_id: ${ACME_CLIENT_ID}
    authorize_url: https://acme.example.com/oauth/authorize
    scope: ["read:contacts", "write:notes"]
  capabilities:
    - id: search_contacts
      input_schema:
        type: object
        properties:
          query: { type: string }
      output_schema:
        type: object
        properties:
          contacts: { type: array, items: { ... } }
```

Once registered, the connector becomes available to your Le Chat workspace and any MCP host using `le-chat-mcp`.

### FAQ

**Q: Is Le Chat free?**
A: Yes — Le Chat has a generous free tier including connectors. Pro plan unlocks higher message quotas and frontier models. Pricing on mistral.ai/pricing.

**Q: Why use Le Chat connectors instead of writing my own MCP servers?**
A: Le Chat connectors handle OAuth, scope validation, and error mapping in one place. Writing your own MCP for Slack means re-implementing rate limits, retries, and pagination. The trade-off: Le Chat connectors require a Mistral account and route calls through their cloud.

**Q: Can I self-host the connectors?**
A: Custom connectors you build are owned by you and can route to any backend. The first-party Le Chat connectors (Slack, Notion, etc) are operated by Mistral. For full self-host, look at MCP-native servers like @modelcontextprotocol/server-slack.

## 快速使用

## 简介

Mistral 的 Le Chat 自带 connector 生态 —— Slack / Notion / Google Drive / Linear / Figma / GitHub 的预校验工具定义。每个 connector 是带 scope、能力、错误码的类型化契约。同一个 connector schema 可以露出成 MCP server，让 Claude Code / Cursor / Codex CLI 直接调用 Le Chat 的 connector。适合需要读写企业 SaaS 又不想每个工具都自己写 MCP 代码的 agent。兼容 Le Chat（原生）和 Claude Code / Cursor / 任意 MCP 宿主（通过 le-chat-mcp）。装机时间 5 分钟（Mistral 账号 + connector OAuth）。

### Connector 库里有啥

| Connector | 读 | 写 |
|---|---|---|
| Slack | channel / 消息 / 用户 | 发消息、加反应 |
| Notion | 页面 / 数据库 | 创建/更新页面、查 DB |
| Google Drive | 文件 / 文件夹 / 内容 | 上传、评论 |
| Linear | issue / project / cycle | 创建/更新 issue |
| Figma | 文件 / frame / 组件 | 评论、版本 |
| GitHub | 仓库 / PR / issue | 评论、打 label |

### 在 Le Chat 里用 connector

```bash
# Le Chat 网页 UI 里 → Connectors → 启用 Slack/Notion/etc → OAuth 登录
# 然后一句普通 prompt：
"Find every Linear issue tagged 'urgent' assigned to me, summarize, and post to #engineering on Slack"
```

Le Chat 自己规划调用、请求审批、执行。

### 从 Claude Code 用 Le Chat connector

加到 MCP 配置：

```json
{
  "mcpServers": {
    "lechat-connectors": {
      "command": "npx",
      "args": ["-y", "le-chat-mcp"],
      "env": {
        "LECHAT_API_KEY": "your-key",
        "LECHAT_CONNECTORS": "slack,notion,linear,gdrive"
      }
    }
  }
}
```

Claude Code 现在能调用：
- `lechat_slack_search`
- `lechat_notion_query_database`
- `lechat_linear_create_issue`
- `lechat_gdrive_upload`
- ……都走 Le Chat 预校验的 schema。

### 自建 connector

```yaml
# my-connector.yaml — 通过 Mistral API 注册
connector:
  id: my-internal-crm
  name: Acme CRM
  oauth:
    client_id: ${ACME_CLIENT_ID}
    authorize_url: https://acme.example.com/oauth/authorize
    scope: ["read:contacts", "write:notes"]
  capabilities:
    - id: search_contacts
      input_schema:
        type: object
        properties:
          query: { type: string }
      output_schema:
        type: object
        properties:
          contacts: { type: array, items: { ... } }
```

注册后 connector 在你的 Le Chat 工作区生效，任何用 `le-chat-mcp` 的 MCP 宿主也能用。

### FAQ

**Q: Le Chat 免费吗？**
A: Le Chat 有大方的免费档，包括 connector。Pro 套餐解锁更高消息额度和前沿模型。价格见 mistral.ai/pricing。

**Q: 为啥用 Le Chat connector 不自己写 MCP server？**
A: Le Chat connector 把 OAuth、scope 校验、错误映射都打包了。自己写 Slack MCP 要重做限速、重试、分页。代价：Le Chat connector 需要 Mistral 账号，调用要经过他们的云。

**Q: connector 能自托管吗？**
A: 你自己建的 connector 归你所有，可以路由到任何后端。第一方 Le Chat connector（Slack / Notion 等）由 Mistral 运营。完全自托管看 MCP 原生 server，比如 @modelcontextprotocol/server-slack。
