What the code does

We read the source, 8 h ago · rules 3dff92dd89df

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

        os.path.exists("/.dockerenv")

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add biz.dfch.specmgr -- uvx biz-dfch-specmgr
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "biz.dfch.specmgr": {
      "args": [
        "biz-dfch-specmgr"
      ],
      "command": "uvx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.biz.dfch.specmgr]
command = "uvx"
args = ["biz-dfch-specmgr"]
.cursor/mcp.json
{
  "mcpServers": {
    "biz.dfch.specmgr": {
      "args": [
        "biz-dfch-specmgr"
      ],
      "command": "uvx"
    }
  }
}
.vscode/mcp.json
{
  "mcpServers": {
    "biz.dfch.specmgr": {
      "args": [
        "biz-dfch-specmgr"
      ],
      "command": "uvx"
    }
  }
}

This one needs environment variables set before it will start: SPECMGR_MCP_TRANSPORT (Transport mode for the MCP server.), SPECMGR_MCP_HOST (Bind address, SSE transport only.), SPECMGR_MCP_PORT (TCP port, SSE transport only.), SPECMGR_ADR_DIR (Base directory scanned for Architecture Decision Record (.md) files.). The author declared them in the registry entry; get the values from the project itself.

SpecMgr — questions

Answers built from our own checks of this server.

Why is there no uptime for SpecMgr?
SpecMgr runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package biz-dfch-specmgr was installed 3 785 times last week.
How do I connect SpecMgr?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls biz-dfch-specmgr straight from pypi; nothing to host, nothing to sign up for.
How many people use SpecMgr?
The pypi package biz-dfch-specmgr was installed 3 785 times in the last week. Week over week that is +38%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is SpecMgr open source?
Yes — it is published under the AGPL-3.0 licence, written in Python, 1 stars on GitHub and 20 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
