Instantly MCP

即时MCP服务器（Python）

一个轻量级、健壮的模型上下文协议（MCP）服务器，用于 即时.ai V2 API，使用FastMCP构建。

特性

• 38工具 涵盖6个类别（帐户、活动、潜在客户、电子邮件、分析、背景知识）
• 双重运输支持：HTTP（远程部署）+stdio（本地）
• 延迟加载：通过仅加载特定的工具类别来减少上下文窗口
• 多租户支持：HTTP部署的请求API密钥
• 全面的错误处理：详细的、可操作的错误消息
• 速率限制：从API响应标头自动跟踪
• 动态超时：搜索和批量操作的超时时间延长

快速开始

安装

# Clone or navigate to the repository
cd instantly-mcp-python

# Install with pip
pip install -e .

# Or install dependencies directly
pip install fastmcp httpx pydantic python-dotenv

配置

立即设置您的API密钥：

export INSTANTLY_API_KEY="your-api-key-here"

或者创建一个 .env 文件：

INSTANTLY_API_KEY=your-api-key-here

运行服务器

HTTP模式（建议用于远程部署）

# Using FastMCP CLI
fastmcp run src/instantly_mcp/server.py --transport http --port 8000

# Using Python directly
python -m instantly_mcp.server --transport http --port 8000

# Or with uvicorn for production
uvicorn instantly_mcp.server:mcp.app --host 0.0.0.0 --port 8000

stdio模式（本地开发）

# Using FastMCP CLI
fastmcp run src/instantly_mcp/server.py

# Using Python directly
python -m instantly_mcp.server

工具类别

账户（6个工具）

活动（8个工具）

线索（12个工具）

电子邮件（6个工具）

分析（3个工具）

后台作业（2个工具）

延迟加载（上下文窗口优化）

通过仅加载所需的类别来减少上下文窗口的使用：

# Load only accounts and campaigns (14 tools instead of 38)
export TOOL_CATEGORIES="accounts,campaigns"

# Load only leads and analytics
export TOOL_CATEGORIES="leads,analytics"

有效类别： accounts, campaigns, leads, emails, analytics, background_jobs

身份验证方法

服务器支持多种身份验证方法以提高灵活性：

1.基于URL的身份验证

将API密钥直接包含在URL路径中：

https://your-server.com/mcp/YOUR_API_KEY

2.报头认证

URL: https://your-server.com/mcp
Header: Authorization: YOUR_API_KEY

*注意：承载令牌前缀是可选的*

3.自定义标题

URL: https://your-server.com/mcp
Header: x-instantly-api-key: YOUR_API_KEY

4.环境变量

export INSTANTLY_API_KEY="your-api-key-here"

MCP客户端配置

克劳德桌面版

添加到 ~/Library/Application Support/Claude/claude_desktop_config.json:

stdio模式（本地）

{
  "mcpServers": {
    "instantly": {
      "command": "python",
      "args": ["-m", "instantly_mcp.server"],
      "env": {
        "INSTANTLY_API_KEY": "your-api-key-here"
      }
    }
  }
}

带有URL认证的HTTP模式（推荐）

{
  "mcpServers": {
    "instantly": {
      "url": "https://your-server.com/mcp/YOUR_API_KEY"
    }
  }
}

带标头身份验证的HTTP模式

{
  "mcpServers": {
    "instantly": {
      "url": "https://your-server.com/mcp",
      "transport": "streamable-http",
      "headers": {
        "Authorization": "your-api-key-here"
      }
    }
  }
}

光标IDE

添加到 ~/.cursor/mcp.json:

使用URL身份验证

{
  "mcpServers": {
    "instantly": {
      "url": "https://your-server.com/mcp/YOUR_API_KEY"
    }
  }
}

使用标头身份验证

{
  "mcpServers": {
    "instantly": {
      "url": "https://your-server.com/mcp",
      "transport": "streamable-http",
      "headers": {
        "x-instantly-api-key": "your-api-key-here"
      }
    }
  }
}

Dockerfile（备选）

FROM python:3.11-slim

WORKDIR /app

COPY pyproject.toml .
COPY src/ src/

RUN pip install -e .

EXPOSE 8000

CMD ["python", "-m", "instantly_mcp.server", "--transport", "http", "--host", "0.0.0.0", "--port", "8000"]

多租户HTTP模式

对于为多个用户提供服务的部署，服务器支持per-request API密钥：

# Start server without default API key
python -m instantly_mcp.server --transport http --port 8000

# Clients provide API key via header
curl -X POST http://localhost:8000/mcp \
  -H "x-instantly-api-key: user-specific-api-key" \
  -H "Content-Type: application/json" \
  -d '{"method": "tools/list"}'

错误处理

服务器提供详细的、可操作的错误消息：

{
  "error": {
    "code": "invalid_api_key",
    "message": "Instantly API key is required. Provide via:\n  - INSTANTLY_API_KEY environment variable\n  - api_key parameter\n  - x-instantly-api-key header (HTTP mode)"
  }
}

速率限制

服务器自动跟踪API响应头中的速率限制：

# Access via get_server_info tool
{
  "rate_limit": {
    "remaining": 95,
    "limit": 100,
    "reset_at": "2024-01-15T12:00:00"
  }
}
