概览

AI 生成的概览

让助手查询 PostHog 产品分析数据，包括事件、用户、洞察、仪表盘、功能开关、群组和实验。

可以做什么
将 PostHog REST API（v1）封装为 MCP 工具。读取类工具包括 list_events、get_person、list_persons、list_dashboards、get_dashboard、execute_insight、list_feature_flags、evaluate_feature_flag、list_cohorts、list_experiments、get_experiment、list_actions 和 get_project_info。助手可借此获取事件与用户数据、运行已保存的洞察、查看某用户的功能开关状态，以及检查实验结果。
适用场景
适合希望在对话中直接获得 PostHog 产品分析答案的场景，例如最近事件、活跃用户、仪表盘状态、功能开关发布比例、群组人数或 A/B 测试结果，无需切换到 PostHog 界面。
运行要求
以 stdio 方式在本地运行，通常通过 npx posthog-mcp-server 启动，因此需要 Node.js。需要 PostHog 个人 API 密钥，放在 POSTHOG_API_KEY；可选 POSTHOG_HOST（默认 POSTHOG_PROJECT，若项目为空则需在每次调用时指定。需要能访问 PostHog 实例的网络。
安装前请注意
该服务器会在客户端配置中保存 PostHog 个人 API 密钥（POSTHOG_API_KEY），建议仅授予读取权限。查询会把分析数据（含用户级明细）发送给助手及其模型提供商。文档列出的工具为只读，但若密钥权限更广，助手可访问的范围也会扩大。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Posthog Mcp Server，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

其他 MCP 客户端

参照 仓库 中的启动说明。

Quick Start

1. Get a PostHog API Key

Go to PostHog → Settings → Personal API Keys and create a key with read access.

Or visit: https://your-instance.posthog.com/settings/user-api-keys

2. Configure your MCP client

Claude Desktop — add to claude_desktop_config.json:

json
{  "mcpServers": {    "posthog": {      "command": "npx",      "args": ["-y", "posthog-mcp-server"],      "env": {        "POSTHOG_API_KEY": "phx_YOUR_API_KEY_HERE",        "POSTHOG_HOST": "https://us.i.posthog.com",        "POSTHOG_PROJECT": "YOUR_PROJECT_ID"      }    }  }}

Cursor — add to MCP settings (.cursor/mcp.json):

json
{  "mcpServers": {    "posthog": {      "command": "npx",      "args": ["-y", "posthog-mcp-server"],      "env": {        "POSTHOG_API_KEY": "phx_YOUR_API_KEY_HERE",        "POSTHOG_HOST": "https://us.i.posthog.com",        "POSTHOG_PROJECT": "YOUR_PROJECT_ID"      }    }  }}

3. Run manually (for testing)

bash
# Clone and buildgit clone https://github.com/friendlygeorge/posthog-mcp-server.gitcd posthog-mcp-servernpm installnpm run build
# RunPOSTHOG_API_KEY=phx_... POSTHOG_PROJECT=12345 node dist/index.js

Environment Variables

VariableRequiredDefaultDescription
POSTHOG_API_KEY✅—Your PostHog personal API key (phx_...)
POSTHOG_HOST❌https://us.i.posthog.comPostHog instance URL (use https://eu.i.posthog.com for EU)
POSTHOG_PROJECT❌""Default project ID. If empty, must be specified per-call.

Self-hosted PostHog

If you run PostHog on your own infrastructure, set POSTHOG_HOST to your instance URL:

POSTHOG_HOST=https://posthog.yourcompany.com

Example Queries

Once configured, ask your AI assistant:

  • "Show me the last 20 pageview events"
  • "Who are the most active users this week?"
  • "What's the status of our signup conversion experiment?"
  • "Is the new-checkout-flow feature flag enabled for user abc123?"
  • "Show me all active dashboards"
  • "Execute insight 42 and show me the trend"
  • "List all feature flags that are currently active"
  • "How many people are in the 'Power Users' cohort?"
