DME MCP Server

MCP Server for DME storage O&M

Exposes 16 action modules (427 actions) from dme-python-sdk as MCP V1 tools

• MCP V1 (mcp>=1.28,<2, FastMCP)

• Endpoint: a single root MCP Server at <endpoint>/mcp/v1 (e.g. http://127.0.0.1:8000/mcp/v1) — all module tools are registered on this one server, no per-module mounts

• Tool naming: dot-separated <topic>.<action_key> (e.g. san.lun_list)

• Annotation: every tool carries annotations.topic (e.g. san), annotations.subtopic (e.g. lun) and annotations.action (e.g. list) — extension fields

• Docstring parsing: action function docstrings are parsed into the tool's description / inputSchema (parameter descriptions) / outputSchema (Returns fields); supports both the Chinese (default branch) and English (main-en branch) docstrings of dme-python-sdk

• Blacklist: modeled after cli.py; ~/.config/pydme/blacklist.json takes precedence. Every blacklisted tool gets an extra optional accept_risk parameter (default from --accept-risk / DME_ACCEPT_RISK); calling it without accept_risk=true is rejected with a RISK_BLOCKED response telling the caller to set it explicitly

Installation

Usage

# streamable-http (default); DME connection params match the pydme CLI.
# Listens on 127.0.0.1:8000 unless --mcp-server or DME_MCP_SERVER is set.
dme-mcp-server --mcp-server 0.0.0.0:8000 \
  --endpoint https://192.168.1.100:26335 --user admin --password xxx

# Or use environment variables (omitting --mcp-server uses the 127.0.0.1:8000 default)
export DME_API_ENDPOINT=https://192.168.1.100:26335
export DME_API_USERNAME=admin
export DME_API_PASSWORD=xxx
dme-mcp-server

# stdio mode (--mcp-server is just a startup switch)
dme-mcp-server --mcp-server x --mcp-transport stdio \
  --endpoint ... --user ... --password ...

Connecting

All module tools live on a single root MCP server. Point your MCP client at:

• http://<host>:<port>/mcp/v1 — e.g. http://127.0.0.1:8000/mcp/v1

tools/list returns every action from all modules; each tool is named <topic>.<action_key>, so clients can group/filter by module on the <topic> prefix. Every tool also carries annotations.topic / annotations.subtopic / annotations.action (non-standard extension fields, for reference).
