What the code does

We read the source, 4 d ago · rules ccca72095570

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.

File ships in the package but is absent from the source [пакет] _version.py:1
этот файл ставится пользователю, но в репозитории его нет
    subprocess.run(cmd, cwd=cwd, check=True)  # nosec B603

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 mcp-server-for-oscal -- uvx mcp-server-for-oscal
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "mcp-server-for-oscal": {
      "args": [
        "mcp-server-for-oscal"
      ],
      "command": "uvx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.mcp-server-for-oscal]
command = "uvx"
args = ["mcp-server-for-oscal"]
.cursor/mcp.json
{
  "mcpServers": {
    "mcp-server-for-oscal": {
      "args": [
        "mcp-server-for-oscal"
      ],
      "command": "uvx"
    }
  }
}
.vscode/mcp.json
{
  "mcpServers": {
    "mcp-server-for-oscal": {
      "args": [
        "mcp-server-for-oscal"
      ],
      "command": "uvx"
    }
  }
}

This one needs environment variables set before it will start: BEDROCK_MODEL_ID (AWS Bedrock model ID for OSCAL documentation queries), OSCAL_KB_ID (AWS Bedrock Knowledge Base ID for OSCAL documentation), AWS_PROFILE (AWS CLI profile name for credential resolution), AWS_REGION (AWS region for Bedrock API calls), LOG_LEVEL (Logging verbosity level (DEBUG, INFO, WARNING, ERROR)). The author declared them in the registry entry; get the values from the project itself.

MCP Server for OSCAL — questions

Answers built from our own checks of this server.

Why is there no uptime for MCP Server for OSCAL?
MCP Server for OSCAL 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 mcp-server-for-oscal was installed 1 249 times last week.
How do I connect MCP Server for OSCAL?
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 mcp-server-for-oscal straight from pypi; nothing to host, nothing to sign up for.
How many people use MCP Server for OSCAL?
The pypi package mcp-server-for-oscal was installed 1 249 times in the last week. Week over week that is -5%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is MCP Server for OSCAL open source?
Yes — it is published under the Apache-2.0 licence, written in Python, 0 stars on GitHub and 4 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
