WeChat MCP Excel Contact Server

中文 | English

</div>

An MCP server that automates WeChat on macOS using Accessibility APIs and screen capture. This package focuses on Excel-driven contact requests, reusable add-friend flows, and friend-request status checks for local outreach workflows.

Features

• 📨 Fetch recent messages from any chat (contact or group)
• ✍️ Send automated replies based on chat history
• 📷 Publish text-only Moments posts, with optional draft-only mode
• 👥 Add contacts using WeChat ID with configurable privacy
• 📊 Read selected Excel rows into WeChat contact request payloads
• 🔁 Monitor pending friend requests, classify whether they were accepted, and persist local state for later processing
• 🧾 Write operator-friendly CSV state plus JSONL audit events
• 🔍 Smart chat search with exact name matching
• 🤖 5 specialized Claude Code sub-agents for smart WeChat automation

Quick Start

Installation

uv tool install git+https://github.com/zbvxbb622-code/wechat-mcp-friend-automation.git

After installation, initialize the local state files and print the exact first-run commands:

wechat-mcp-bootstrap
wechat-mcp-doctor

wechat-mcp-bootstrap safely creates the default wechat-followup-state/ directory, monitor_state.csv, monitor_events.jsonl, the production wechat-outreach-state/ directory, and the default logs/ directory without overwriting existing files. wechat-mcp-doctor reports PASS or ACTION REQUIRED for the Python/uv runtime boundary, WeChat installation and login, macOS Accessibility readiness, writable state, and MCP registration guidance. The installed console scripts run directly; uv is needed for this install command and for the source-checkout workflow below, not for the already-installed wechat-mcp command.

Setup with Claude Code

# If installed as a uv tool
claude mcp add --transport stdio wechat-mcp -- wechat-mcp

# If using uv for development
claude mcp add --transport stdio wechat-mcp -- uv --directory $(pwd) run wechat-mcp

<details> <summary>Setup with Claude Desktop</summary>

// If installed as a uv tool
{
  "mcpServers": {
    "wechat-mcp": {
      "type": "stdio",
      "command": "wechat-mcp"
    }
  }
}

// If using uv for development
{
  "mcpServers": {
    "wechat-mcp": {
      "type": "stdio",
      "command": "uv",
      "args": [
        "--directory",
        "{path/to/wechat-mcp}",
        "run",
        "wechat-mcp"
      ],
    }
  }
}

</details>

<details> <summary>Setup with Codex</summary>

# If installed as a uv tool
codex mcp add wechat-mcp -- wechat-mcp

# If using uv for development
codex mcp add wechat-mcp -- uv --directory $(pwd) run wechat-mcp

</details>

macOS Permissions

⚠️ Important: Grant Accessibility permissions to your terminal:

1. Open WeChat for Mac and sign in with the QR code or phone login.
2. Open System Settings → Privacy & Security → Accessibility
3. Add and enable the terminal/IDE that launches the MCP command (Terminal.app, iTerm2, etc.)
4. Run wechat-mcp-doctor and resolve every ACTION REQUIRED check before using the server.

The bootstrap command prints these one-time steps and both exact registration commands:

# Claude Code
claude mcp add --transport stdio wechat-mcp -- wechat-mcp

# Codex
codex mcp add wechat-mcp -- wechat-mcp

Usage

Basic Commands

# Re-run first-run checks at any time
wechat-mcp-doctor

# Run one production outreach scheduling pass
wechat-outreach-run --input-xlsx /path/to/contacts.xlsx --sheet-name 独家达人 --once

# Run with default stdio transport
wechat-mcp --transport stdio

# Run with HTTP transport
wechat-mcp --transport streamable-http

# Run with SSE transport
wechat-mcp --transport sse

# Poll pending friend requests once and write monitor_state.csv / monitor_events.jsonl
wechat-followup-monitor --workbook /path/to/contacts.xlsx --sheet-name 独家达人 --rows 3-6 --once

Available MCP Tools

• fetch_messages_by_chat - Get recent messages from a chat
• reply_to_messages_by_chat - Send a reply to a chat
• add_contact_by_wechat_id - Add a new contact using a WeChat ID and send a friend request
• read_wechat_contacts_from_excel - Read selected Excel rows into friend-request payloads
• add_contacts_from_excel_rows - Read selected Excel rows and add contacts
• check_contact_status - Classify a contact as added, waiting, not_added, not_found, or unknown
• publish_moment_without_media - Publish a text-only Moments post (no photos or videos); optionally only prepare a draft without posting via publish=False

See detailed API documentation for full tool specifications.

The repository also includes local follow-up helpers and runner scripts for stateful workflows, but the default MCP registry intentionally keeps direct accepted-contact send tools hidden.

Excel Contact Workflow

Defaults match the tested creator resource sheet:

• nickname_col: B
• redbook_id_col: C
• wechat_id_col: AZ
• start_row: 3
• request_message: 你好，想和你沟通商务合作
• remark_template: 小红书-{nickname}-{redbook_id}
• Batch add delay: delay_seconds=10 by default between contacts
• Cooldown: after every 20 contacts, wait 10 minutes before continuing
• Cooldown check: re-check pending contacts after cooldown, update local state files, and record unresolved contacts for later processing
• Optional shared QR image: pass one followup_image_path / --followup-image and the same QR image is sent to every accepted contact after the text message

Example MCP arguments for a preview:

{
  "workbook_path": "/path/to/contacts.xlsx",
  "sheet_name": "独家达人",
  "rows": "3,5-8"
}

Example MCP arguments for a dry run:

{
  "workbook_path": "/path/to/contacts.xlsx",
  "sheet_name": "独家达人",
  "rows": "3-6",
  "dry_run": true
}

When running a real batch, the server spaces out add attempts and cools down after every 20 contacts by default:

{
  "workbook_path": "/path/to/contacts.xlsx",
  "sheet_name": "独家达人",
  "rows": "3-42",
  "delay_seconds": 10,
  "cooldown_after_contacts": 20,
  "cooldown_seconds": 600,
  "followup_image_path": "/path/to/wecom-qr.png"
}

Follow-Up Monitor

This repository includes local follow-up helpers for operator-run workflows. Direct accepted-contact send helpers are not registered as default MCP tools.

wechat-followup-monitor keeps the post-request workflow running without leaving a Codex chat open.

Defaults:

• Check interval: 30 minutes
• Max wait: 72 hours
• State files: wechat-followup-state/monitor_state.csv and wechat-followup-state/monitor_events.jsonl
• Follow-up message: 你好，想和你进一步沟通商务合作，方便时请回复这条消息
• Send failures are recorded as send_failed and are not retried automatically

Run wechat-mcp-bootstrap --state-dir /path/to/wechat-followup-state to create these state files before the first batch or monitor run. Existing CSV/JSONL files are preserved.

Example:

wechat-followup-monitor \
  --workbook /path/to/contacts.xlsx \
  --sheet-name 独家达人 \
  --rows 3-6 \
  --followup-image /path/to/wecom-qr.png

For a safe test without touching WeChat:

wechat-followup-monitor \
  --workbook /path/to/contacts.xlsx \
  --rows 3 \
  --once \
  --dry-run \
  --dry-run-status waiting

Production Outreach Runner

wechat-outreach-run is the production closed-loop entrypoint. It keeps an internal queue in wechat-outreach-state/run_state.json, exports operator views as:

• wechat-outreach-state/输入快照.xlsx
• wechat-outreach-state/待处理表.xlsx
• wechat-outreach-state/成功表.xlsx
• wechat-outreach-state/失败表.xlsx

Default behavior:

• Work window: 10:00-24:00 local time
• One WeChat action at a time
• Global deduplication by wechat_id
• Fixed follow-up delay: 5-15 minutes after acceptance
• Single-instance lock: wechat-outreach-state/.wechat-outreach.lock
• Circuit-breaker evidence: wechat-outreach-state/evidence/

Resume after a pause:

• wechat-outreach-run --state-dir /path/to/wechat-outreach-state --resume
• When a circuit breaker pauses the run, resume only continues unfinished people from 待处理表.xlsx.
• 成功表.xlsx and 失败表.xlsx are never retried automatically.

Example:

wechat-outreach-run \
  --input-xlsx /path/to/contacts.xlsx \
  --sheet-name 独家达人 \
  --rows 3-40 \
  --followup-image /path/to/wecom-qr.png
