wecom-docs-mcp-server
Provides document CRUD operations for WeCom (Enterprise WeChat) Docs and Smartsheets, including creating, reading, and editing documents and structured tables via the @wecom/cli API.
wecom-docs-mcp-server
MCP server for WeCom (企业微信 / Enterprise WeChat) document operations — create, read, and edit WeCom Docs and Smartsheets from any MCP-compatible AI agent.
Gap this fills: Existing WeCom MCP servers (wecom-bot-mcp-server, wecom-mcp) only support sending messages via webhook. This server provides document CRUD operations via the
@wecom/clidocument API.
Compatible with: Claude Desktop · Hermes Agent · Cursor · any MCP client

Why This Exists (The Silent Failure Problem)
Calling wecom-cli from WSL via bash hits a three-layer failure:
UNC path issue —
cmd.exelaunches with wrong working directory under WSLExit code lies — process returns 0 but writes nothing
Chinese encoding — shell argument boundary corrupts multi-byte characters
Fix: call node.exe directly via subprocess.run([...], capture_output=True) — no shell, args pass through CreateProcessW, Chinese content works correctly.
# ❌ silently fails from WSL
os.system(f'wecom-cli doc edit_doc_content --json "{json_content}"')
# ✅ works
subprocess.run(["node.exe", WECOM_JS, "doc", "edit_doc_content", "--json", json_content],
capture_output=True)Requirements

export NODE_EXE="node.exe"Usage Examples
Create a document and write content
User: Create a WeCom doc called "Q2 Market Report" and write a brief summary
Agent calls:
1. wecom_create_doc(doc_name="Q2 Market Report", doc_type=3)
→ {"url": "https://doc.weixin.qq.com/doc/xxx", "docid": "abc123"}
2. wecom_edit_doc(content="# Q2 Market Report\n\n...", docid="abc123")
→ {"errcode": 0, "errmsg": "ok"}Create a smartsheet with structured data
User: Create a competitor tracking table with columns: Company, Product, Funding, Notes
Agent calls:
1. wecom_create_doc(doc_name="Competitor Tracker", doc_type=10)
→ {"url": "...", "docid": "xyz789"}
2. wecom_smartsheet_get_sheet(url="...")
→ {"sheet_list": [{"sheet_id": "s001", "title": "Sheet1"}]}
3. wecom_smartsheet_setup_fields(sheet_id="s001", field_names=["Company", "Product", "Funding", "Notes"])
4. wecom_smartsheet_add_records(sheet_id="s001", records=[
{"Company": "HashKey", "Product": "HashKey Exchange", "Funding": "$200M", "Notes": "SFC licensed"},
{"Company": "OSL", "Product": "OSL Exchange", "Funding": "$150M", "Notes": "SFC licensed"}
])Read an existing document
User: What's in this doc? https://doc.weixin.qq.com/doc/abc?scode=xyz
Agent calls:
wecom_read_doc(url="https://doc.weixin.qq.com/doc/abc?scode=xyz")
→ Returns full Markdown contentTroubleshooting
node.exe not found
# WSL: ensure Windows Node is on PATH
export PATH=$PATH:/mnt/c/Program\ Files/nodejsEmpty doc after create+edit
Set WECOM_CLI_PATH explicitly — auto-detection may have picked wrong wecom.js.
Error 851008 — Bot lacks "get member document content" permission. Re-authorize in WeCom admin console → Application Management → your app → Permissions.
Error 851014 — Document permission expired. Same re-authorization flow.

简介
wecom-docs-mcp-server 是一个 MCP stdio 服务器，将企业微信文档操作（创建、读取、编辑文档和智能表格）暴露为 MCP 工具，可在 Claude Desktop、Hermes Agent、Cursor 等任何 MCP 客户端中使用。
与已有企微 MCP 项目的区别：现有项目（wecom-bot-mcp-server、wecom-mcp）均只支持通过 Webhook 发送消息；本项目专注于文档 CRUD 操作，使用 @wecom/cli 文档 API。
核心技术问题
从 WSL 通过 bash 调用 wecom-cli 会静默失败（exit code 0，但文档为空）。原因是 UNC 路径问题 + cmd.exe 工作目录错误 + 中文编码失败三层叠加。
解决方案：直接用 subprocess.run(["node.exe", ...]) 调用，绕过 shell，通过 CreateProcessW 传参，中文内容完全正常。
