MCP Gateway & Registry v1.0.4

MCP Gateway & Registry v1.0.4

Release Date: October 14, 2025

We're excited to announce v1.0.4 of the MCP Gateway & Registry - featuring major enhancements for Anthropic MCP Registry integration, environment variable management, and improved documentation.

What's New

Anthropic MCP Registry Integration

Seamlessly integrate with Anthropic's official MCP Registry to import and access curated MCP servers through your gateway!

Import Servers from Anthropic Registry (#171)

• One-Command Import - Import curated MCP servers with a single command
• Automatic Configuration - Server metadata, authentication, and tags automatically configured
• Environment Variable Substitution - API keys and credentials automatically substituted from .env file
• Bulk Import Support - Import multiple servers from a list file
• Unified Access - Access imported servers through your gateway with centralized authentication

Anthropic Registry REST API v0 Compatibility (#178)

• Full API Compatibility - Complete support for Anthropic's Registry REST API v0 specification
• Server Discovery - List available servers programmatically with JWT authentication
• Version Information - Retrieve server versions and compatibility details
• Programmatic Access - Point your Anthropic API clients to this registry

Documentation:

• Anthropic Registry Import Guide - Comprehensive guide for importing servers
• Registry REST API v0 Documentation - API reference and examples

Example Usage:

# Import a single server
./cli/import_from_anthropic_registry.sh ai.smithery/smithery-ai-github

# Import from a curated list
./cli/import_from_anthropic_registry.sh --import-list cli/import_server_list.txt

# List available servers via API
curl https://your-gateway/v0/servers \
  -H "Authorization: Bearer YOUR_TOKEN"

Enhanced Authentication & Environment Management

Automatic Environment Variable Substitution (#181)

• Smart Header Processing - Authentication headers automatically populated from environment variables
• Import-Time Substitution - Environment variables substituted during server import, not at runtime
• Simplified Configuration - No need to pass environment variables to Docker containers
• Auto-Load .env File - Import script automatically sources .env file

Before:

# Manual environment variable management
source .env
export SMITHERY_API_KEY
./cli/import_from_anthropic_registry.sh server-name

After:

# Automatic - just run the import
./cli/import_from_anthropic_registry.sh server-name

Bug Fixes

UI Improvements

• Fixed proxy_pass_url Display - UI now correctly shows upstream URLs for imported servers
• Added Missing Field - /servers API endpoint now includes proxy_pass_url in response

Model Download Optimization (#176)

• Removed Redundant Download - Eliminated model download from registry entrypoint
• Faster Startup - Registry container starts faster with pre-downloaded models
• Better User Experience - Model download now handled by setup scripts

Documentation Improvements

New Documentation

• Anthropic Registry Import Guide - Complete guide for importing servers from Anthropic's registry
• REST API v0 Documentation - Full API reference for Anthropic registry compatibility
• Enhanced README - More concise with better organization and navigation

README Updates

• Condensed "What's New" section (reduced from 14 to 6 key items)
• Simplified deployment and infrastructure details
• Added Anthropic documentation links to docs table
• Removed verbose sections for better readability

macOS Setup Guide Updates (#177)

• Updated installation instructions for macOS users
• Platform-specific optimizations and troubleshooting

Roadmap Updates

Completed Features

• #171 - Import Servers from Anthropic MCP Registry
• #37 - Multi-Level Registry Support (via Anthropic integration)

These features enable federated registry support and seamless integration with the broader MCP ecosystem.

Breaking Changes

None - this release is fully backward compatible with v1.0.3.

Upgrade Instructions

For Existing Installations

1. Pull the latest changes:

cd mcp-gateway-registry
git pull origin main

2. Update environment configuration: Add any new API keys to your .env file:

# Example: Smithery API key for imported servers
SMITHERY_API_KEY=your-api-key-here

3. Restart services:

./build_and_run.sh

For Pre-built Image Users

cd mcp-gateway-registry
git pull origin main
./build_and_run.sh --prebuilt

Migration Notes

Importing Servers

If you want to import servers from Anthropic's registry:

1. Add required API keys to .env:

# Add authentication keys for services you want to import
SMITHERY_API_KEY=your-key
OTHER_SERVICE_KEY=your-key

2. Create import list:

# Create cli/import_server_list.txt with desired servers
echo "ai.smithery/smithery-ai-github" >> cli/import_server_list.txt
echo "io.github.jgador/websharp" >> cli/import_server_list.txt

3. Run import:

./cli/import_from_anthropic_registry.sh --import-list cli/import_server_list.txt

Known Issues

• Authentication keys must be valid for successful server imports
• Some Smithery servers may require specific API key permissions
• Imported servers with invalid credentials will show as "auth-expired" in health checks
