# zh-file-mcp `zh-file-mcp` is a stdio-first MCP file gateway. It downloads files from configured business systems into the agent workspace and uploads local workspace files back to those systems. It is intentionally generic: systems such as `wpos` are configured with JSON instead of hard-coded MCP tools. ## Features - Stdio MCP server for Cherry Studio, web-agent, and other MCP clients. - Config-driven HTTP download, upload, list, and metadata requests. - Cookie, bearer, custom header, static headers, and no-auth modes. - Files are written under the MCP process working directory. - Tool results return `relative_path` so agents can continue reading files. - Paths are constrained to the workspace. - Large business IDs can be passed as strings to avoid JavaScript precision loss. ## Tools | Tool | Description | | --- | --- | | `get_workspace_info` | Show current working directory, download root, and configured systems. | | `download_file` | Download a configured system file into the workspace. | | `upload_file` | Upload a workspace file to a configured system. | | `list_files` | List files from a configured system, if the system defines `list`. | | `get_file_info` | Get file metadata, if the system defines `file_info`. | ## Install ```bash cd /Users/linchuanke/lck/zhonghui/zh-file-mcp python3 -m venv .venv source .venv/bin/activate pip install -e . ``` Verify: ```bash /Users/linchuanke/lck/zhonghui/zh-file-mcp/.venv/bin/zh-file-mcp --help ``` After code changes, reinstall: ```bash source .venv/bin/activate pip install -e . ``` Version `0.1.3` and later allow `extra` to be passed either as an object or as a JSON object string. If MCP still reports `extra Input should be a valid dictionary`, the running MCP process is still using an older install; restart the MCP client and make sure its command points to this updated environment. ## Environment | Variable | Default | Description | | --- | --- | --- | | `FILE_MCP_SYSTEMS_JSON` | - | Inline JSON systems co…
