Getting Started

Local Development

1. Install dependencies:

npm install

1. Build the project:

npm run build

1. 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:

| Variable | Default | Description | | --- | --- | --- | | FEDRAMP_DOCS_PATH | ~/.cache/fedramp-docs | Path to an existing FedRAMP/docs checkout. | | FEDRAMP_DOCS_REMOTE | https://github.com/FedRAMP/docs | Remote used when cloning. | | FEDRAMP_DOCS_BRANCH | main | Branch to checkout when cloning. | | FEDRAMP_DOCS_ALLOW_AUTO_CLONE | true | Clone automatically when the path is missing. | | FEDRAMP_DOCS_AUTO_UPDATE | true | Automatically check for and fetch repository updates. | | FEDRAMP_DOCS_UPDATE_CHECK_HOURS | 24 | Hours between automatic update checks (when auto-update is enabled). | | FEDRAMP_DOCS_INDEX_PERSIST | true | Persist the in-memory index under ~/.cache/fedramp-docs/index-v1.json. |

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"
      }
    }
  }
}

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

Example Evidence Sources by Theme

| Theme | Example Sources | |-------|----------------| | IAM | Okta/Entra MFA policies, AWS IAM credential reports, PAM tools (CyberArk, Vault) | | CNA | AWS Security Groups, VPC Flow Logs, Container scans (Trivy), CSPM (Wiz, Prisma) | | MLA | SIEM config (Splunk, Sentinel), CloudTrail, IaC scans (Checkov, tfsec) | | CMT | Git history, CI/CD pipelines (GitHub Actions), Change tickets (ServiceNow, Jira) | | SVC | TLS scans (SSL Labs), Secrets Manager rotation, Patch compliance (SSM) | | INR | PagerDuty incidents, Post-mortems (Blameless), ServiceNow tickets | | RPL | AWS Backup reports, DR test logs, Chaos engineering results | | TPR | Vendor ratings (SecurityScorecard), Dependency scans (Dependabot, Snyk) |

Usage Example

"What evidence do I need for KSI-IAM-01 (Phishing-Resistant MFA)?"
→ Returns suggested API calls, CLI commands, and artifacts to collect

"Get evidence checklist for the CNA theme"
→ Returns automation sources for all Cloud Native Architecture indicators

See src/tools/ for the precise schemas implemented with Zod. Each tool returns either a successful object or an error payload containing code, message, and optional hint.

Usage Examples

When using the MCP server with Claude Desktop or other MCP clients, here are some example queries:

Getting KSI Information:

"List all available FedRAMP documents"
→ Uses list_frmr_documents

"Show me all KSI items for moderate impact systems"
→ Uses filter_by_impact with impact='moderate'

"Give me a summary of the IAM theme requirements"
→ Uses get_theme_summary with theme='IAM'

"What evidence do I need for IAM compliance?"
→ Uses get_evidence_examples with theme='IAM'

Searching Documentation:

"Search for information about continuous monitoring"
→ Uses search_markdown with query 'continuous monitoring'

"What does 'federal customer data' mean in FedRAMP?"
→ Uses search_definitions with term='federal customer data'

"Get the details for requirement KSI-IAM-01"
→ Uses get_requirement_by_id with id='KSI-IAM-01'

Working with Controls:

"What FedRAMP requirements map to control AY-01?"
→ Uses get_control_requirements with control='AY-01'

"Which control families have the most FedRAMP coverage?"
→ Uses analyze_control_coverage

"Find all markdown files that reference AC-2"
→ Uses grep_controls_in_markdown with control='AC-2'

Analyzing Changes:

"What's new in the latest KSI release?"
→ Uses list_versions then diff_frmr to compare versions

"Show significant change guidance"
→ Uses get_significant_change_guidance

Advanced Queries: Dashboard & Architecture Insights

These prompts combine FedRAMP data with Claude's analytical capabilities to help you design compliance dashboards and features:

Dashboard Architecture:

"Using the FedRAMP KSI data, design a compliance dashboard architecture.
What components would I need? How should I structure the data for real-time monitoring?"

"Get all KSI themes and their indicators. Then recommend how to organize
them into a dashboard with drill-down navigation."

Visualization Design:

"Analyze the FedRAMP control coverage data. What would be the best
chart types to visualize control family coverage? Suggest a color
scheme for compliance status."

"List the KSIs filtered by impact level. Design a risk heat map
visualization showing low/moderate/high impact requirements."

Feature Planning:

"Get the evidence checklist from FedRAMP. How would you build a
feature that tracks evidence collection progress with percentage
completion per KSI theme?"

"What are the requirements for AC-2 (Account Management)? Design a
feature that helps users track their implementation status against
these requirements."

Data Modeling:

"Analyze the structure of KSI indicators and their control mappings.
What database schema would you recommend for a compliance tracking app?"

"Get a theme summary for IAM. How would you model the relationship
between KSIs, NIST controls, and evidence in a graph database?"

Executive Reporting:

"Using the control coverage analysis, design an executive summary
dashboard that shows compliance posture at a glance."

"Analyze all high-impact KSI requirements and create a prioritized
remediation roadmap template."

Tool Search & Deferred Loading

With 21 tools, this MCP server is a great candidate for deferred tool loading (also known as tool search). Instead of loading all tools upfront, clients can load a small set of essential tools and discover the rest on demand via the search_tools tool.

The search_tools Tool

The search_tools tool lets clients discover available tools by keyword or category:

"What tools help with KSI compliance?"
→ search_tools(query="ksi compliance")
→ Returns: list_ksi, get_ksi, filter_by_impact, get_theme_summary, get_evidence_examples

"What analysis tools are available?"
→ search_tools(category="Analysis")
→ Returns: diff_frmr, grep_controls_in_markdown, get_significant_change_guidance

Recommended Non-Deferred Tools

When using deferred loading, keep these 5 tools always loaded:

| Tool | Why Always Loaded | |------|-------------------| | search_tools | Required for discovering other tools | | search_markdown | Most common entry point for documentation queries | | list_frmr_documents | Starting point for FRMR data exploration | | health_check | Diagnostics and status verification | | get_requirement_by_id | Universal ID lookup across all document types |

Claude API Configuration with Deferred Loading

When using the Claude API with mcp_toolset, you can configure deferred loading:

import anthropic

client = anthropic.Anthropic()

response = client.messages.create(
    model="claude-sonnet-4-20250514",
    max_tokens=1024,
    mcp_servers=[
        {
            "type": "stdio",
            "command": "fedramp-docs-mcp",
            "name": "fedramp-docs",
        }
    ],
    messages=[{"role": "user", "content": "..."}],
)

The Claude API will use tool annotations (readOnlyHint, destructiveHint, etc.) to make informed decisions about tool selection. All 21 tools include annotations.

claude mcp add --transport stdio fedramp-docs /path/to/node/bin/fedramp-docs-mcp

# List configured servers
claude mcp list

# Remove if needed
claude mcp remove fedramp-docs

Method 2: Configuration File

Claude Code supports three configuration scopes:

1. Project-scoped (recommended for teams): .mcp.json in project root
2. User-scoped: ~/.claude/settings.local.json
3. Project-local: .claude/settings.local.json in project root

Example .mcp.json (project-scoped, can be version-controlled):

{
  "mcpServers": {
    "fedramp-docs": {
      "command": "fedramp-docs-mcp",
      "args": [],
      "env": {
        "FEDRAMP_DOCS_AUTO_UPDATE": "true"
      }
    }
  }
}

With environment variable expansion:

{
  "mcpServers": {
    "fedramp-docs": {
      "command": "fedramp-docs-mcp",
      "args": [],
      "env": {
        "FEDRAMP_DOCS_PATH": "${HOME}/fedramp-docs",
        "FEDRAMP_DOCS_AUTO_UPDATE": "true"
      }
    }
  }
}

Testing:

• Restart Claude Code after configuration changes
• Use /mcp command for interactive management

See plugin/README.md for full documentation.

Docker

Run the MCP server in a security-hardened Docker container.

Quick Start

# Build the image
docker build -t fedramp-docs-mcp .

# Run interactively (for MCP stdio)
docker run --rm -i \
  --security-opt no-new-privileges:true \
  --cap-drop ALL \
  --read-only \
  --memory 512m \
  -v fedramp-cache:/home/mcpuser/.cache/fedramp-docs \
  fedramp-docs-mcp

Docker Compose

# Start with docker-compose (security hardening included)
docker compose up -d

Claude Desktop with Docker

Configure Claude Desktop to use the Docker container:

{
  "mcpServers": {
    "fedramp-docs": {
      "command": "docker",
      "args": [
        "run", "--rm", "-i",
        "--security-opt", "no-new-privileges:true",
        "--cap-drop", "ALL",
        "--read-only",
        "--memory", "512m",
        "-v", "fedramp-cache:/home/mcpuser/.cache/fedramp-docs",
        "fedramp-docs-mcp:latest"
      ]
    }
  }
}

Security Features

The Docker setup follows 2025 MCP security best practices:

• Non-root user: Runs as mcpuser (UID 1001)
• Read-only filesystem: Prevents unauthorized modifications
• Dropped capabilities: --cap-drop ALL removes all Linux capabilities
• No new privileges: Prevents privilege escalation
• Resource limits: Memory and CPU constraints
• Network isolation: Internal network with no external access by default

Development

Running in Development Mode

Use tsx for rapid iteration without building:

npm run dev

This runs the TypeScript source directly, automatically recompiling on changes.

Running Tests

The repository includes Vitest-based unit and contract tests with small fixtures:

npm test

Tests set FEDRAMP_DOCS_PATH to tests/fixtures/repo, ensuring the indexer, search, and diff logic run deterministically without needing the real FedRAMP repo.

Integration tests validate the indexer against the real upstream FedRAMP/docs clone:

npm run test:integration

These tests clone and index the actual upstream repository, verifying that the parser handles current upstream data correctly. Set FEDRAMP_DOCS_PATH to skip the clone and use an existing checkout. When using your own checkout, also set FEDRAMP_DOCS_AUTO_UPDATE=false to prevent the test from modifying it.

Code Structure

The codebase uses:

• TypeScript 5.4+ with strict mode enabled
• ES Modules ("type": "module" in package.json)
• Node.js module resolution (moduleResolution: "NodeNext")
• Zod for runtime schema validation
• MCP SDK v1.24+ for server implementation

Project Structure

src/
  index.ts                 # MCP bootstrap
  repo.ts                  # repo discovery and cloning
  indexer.ts               # FRMR + markdown indexing logic
  frmr.ts                  # FRMR-centric helpers
  search.ts                # markdown search + aggregations
  diff.ts                  # structured FRMR diff engine
  tools/                   # individual MCP tool handlers

Fixtures live under tests/fixtures, while Vitest specs reside in tests/.

Troubleshooting

Build Errors

Error: Cannot find module '@modelcontextprotocol/sdk'

Ensure you have the correct SDK version installed:

npm install @modelcontextprotocol/sdk@^1.20.0

Error: Module not found or import errors

The project uses ES modules with NodeNext resolution. Make sure you're using Node.js 18+ and that your TypeScript configuration matches:

{
  "compilerOptions": {
    "module": "NodeNext",
    "moduleResolution": "NodeNext"
  }
}

Runtime Errors

Error: REPO_CLONE_FAILED

The server couldn't clone the FedRAMP docs repository. Check:

• Network connectivity
• Set FEDRAMP_DOCS_PATH to an existing local clone, or
• Ensure FEDRAMP_DOCS_ALLOW_AUTO_CLONE=true (default)

Server starts but no tools appear

Verify the build completed successfully:

npm run build
ls dist/  # Should contain index.js, tools/, etc.

Development Issues
