FedRAMP Docs MCP Server

⚠️ This project is sunsetting

This MCP server is no longer under active development. The FedRAMP search and FRMR parsing capabilities are being folded into GRC Clanker and myctrl.tools, where they live inside an actual GRC workflow instead of as a standalone subprocess.

The npm package and this repository remain available for existing users, but no new features will land here. For the reasoning and post-mortem, see the project writeup.

Custom Model Context Protocol (MCP) server that makes the FedRAMP/docs repository queryable with FRMR-aware tooling. The server scans FRMR JSON datasets and supporting markdown guidance, exposes structured tools for analysis, and can optionally clone and cache the upstream repository for you.

Supported Document Types

Getting Started

Local Development

1. Install dependencies:

npm install

2. Build the project:

npm run build

3. Run the server:

node dist/index.js

Global Installation

To install globally and use the fedramp-docs-mcp command:

npm install -g .
fedramp-docs-mcp

Note: Global installation is required if you want to use fedramp-docs-mcp as the command in MCP client configurations (Claude Desktop, Goose, etc.). Alternatively, you can use the full path to the built server: node /path/to/fedramp-docs-mcp/dist/index.js

CLI Commands

The package includes helpful CLI commands:

# Show help and usage information
npx fedramp-docs-mcp help

# Install Claude Code plugin
npx fedramp-docs-mcp setup

# Print MCP server configuration for Claude Desktop/Code
npx fedramp-docs-mcp mcp-config

# Start MCP server (used by MCP clients)
npx fedramp-docs-mcp

During startup the server ensures a FedRAMP/docs repository is available, indexes FRMR JSON and markdown content, then begins serving requests on MCP stdio.

Configuration

Environment variables control repository discovery and indexing behaviour:

Set FEDRAMP_DOCS_PATH if you maintain a local clone. Otherwise leave it unset and allow the server to create a shallow cached copy.

Keeping Data Up-to-Date

The server includes automatic update checking to keep the FedRAMP docs current:

Automatic Updates (Default Behavior):

• Every 24 hours (configurable), the server checks if the cached repository needs updating
• If updates are available, they're fetched automatically on server startup
• This ensures you always have recent FedRAMP data without manual intervention

Manual Updates:

• Use the update_repository tool to force an immediate update
• Example query in Claude Desktop: "Update the FedRAMP docs repository"
• Useful when you know new requirements or guidance has been published

Disabling Auto-Update:

{
  "mcpServers": {
    "fedramp-docs": {
      "command": "fedramp-docs-mcp",
      "env": {
        "FEDRAMP_DOCS_AUTO_UPDATE": "false"
      }
    }
  }
}

Custom Update Frequency (check every 6 hours):

{
  "mcpServers": {
    "fedramp-docs": {
      "command": "fedramp-docs-mcp",
      "env": {
        "FEDRAMP_DOCS_UPDATE_CHECK_HOURS": "6"
      }
    }
  }
}

Available Tools

The server provides 21 tools organized into categories. All tools follow the error model and respond with JSON payloads.

Document Discovery

KSI (Key Security Indicators)

Control Mapping

Search & Lookup

Analysis

Evidence Collection Suggestions

The get_evidence_examples tool provides community-suggested evidence examples for each KSI. These are automation-friendly suggestions showing how to programmatically collect compliance evidence via APIs, CLI commands, and security tools.

Important: These are NOT official FedRAMP guidance. Always verify requirements with official FedRAMP documentation.

What's Included

For each of the 72 KSI indicators, we provide:

• Evidence types: API calls, reports, scans, logs, configurations, documentation
• Automation sources: AWS, Azure, GCP, Okta, Splunk, Terraform, GitHub Actions, etc.
• Example commands: Ready-to-use CLI commands and API endpoints
