Smithsonian Open Access MCP Server

npm version NPM Downloads

A Model Context Protocol (MCP) server that provides AI assistants with access to the Smithsonian Institution's Open Access collections. This server allows AI tools like Claude Desktop to search, explore, and analyze over 3 million collection objects from America's national museums.

Quick Start

Option 1: npm/npx Installation (Easiest)

Integration

Claude Desktop

Option 1: Using npm/npx (Recommended)

Configure (claude_desktop_config.json):

{ "mcpServers": { "smithsonian_open_access": { "command": "npx", "args": ["-y", "@molanojustin/smithsonian-mcp"], "env": { "SMITHSONIAN_API_KEY": "your_key_here" } } } }

Option 2: Using Python installation

Configure (claude_desktop_config.json):

{ "mcpServers": { "smithsonian_open_access": { "command": "python", "args": ["-m", "smithsonian_mcp.server"], "env": { "SMITHSONIAN_API_KEY": "your_key_here" } } } }

Or copy the provided

Test: Ask Claude "What Smithsonian museums are available?"

mcpo Integration (MCP Orchestrator)

mcpo is an MCP orchestrator that converts multiple MCP servers into OpenAPI/HTTP endpoints, ideal for combining multiple services into a single systemd service.

Installation

# Install mcpo pip install mcpo # Or using uvx uvx mcpo --help

Configuration

Create a mcpo-config.json file:

{ "mcpServers": { "smithsonian_open_access": { "command": "python", "args": ["-m", "smithsonian_mcp.server"], "env": { "SMITHSONIAN_API_KEY": "your_api_key_here" } }, "memory": { "command": "npx", "args": ["-y", "@modelcontextprotocol/server-memory"] }, "time": { "command": "uvx", "args": ["mcp-server-time", "--local-timezone=America/New_York"] } } }

Running with mcpo

# Start mcpo with hot-reload mcpo --config mcpo-config.json --port 8000 --hot-reload # With API key authentication mcpo --config mcpo-config.json --port 8000 --api-key "your_secret_key" # Access endpoints: # - Smithsonian: http://localhost:8000/smithsonian_open_access # - Memory: http://localhost:8000/memory # - Time: http://localhost:8000/time # - API docs: http://localhost:8000/docs

Systemd Service

Create /etc/systemd/system/mcpo.service:

[Unit] Description=MCP Orchestrator Service After=network.target [Service] Type=simple User=your-user WorkingDirectory=/path/to/your/config Environment=PATH=/path/to/venv/bin ExecStart=/path/to/venv/bin/mcpo --config mcpo-config.json --port 8000 Restart=always RestartSec=10 [Install] WantedBy=multi-user.target

# Enable and start service sudo systemctl enable mcpo sudo systemctl start mcpo sudo systemctl status mcpo

Troubleshooting mcpo

"ModuleNotFoundError: No module named 'smithsonian_mcp'" This occurs when mcpo can't find the Smithsonian MCP module. Fix by:

Use absolute Python path in your mcpo config:

{ "command": "/full/path/to/your/project/.venv/bin/python", "env": { "PYTHONPATH": "/full/path/to/your/project" } }

Verify paths:

# Check Python executable exists ls -la /path/to/your/project/.venv/bin/python # Test module import /path/to/your/project/.venv/bin/python -c "import smithsonian_mcp; print('OK')"

Regenerate config with setup script:

./setup.sh # Will create mcpo-config.json with correct paths

"Connection closed" errors

Ensure API key is valid and set in environment
Check that the virtual environment has all dependencies installed
Verify the MCP server can start manually: python -m smithsonian_mcp.server --test

"Port 8000 already in use"

# Check what's using the port lsof -i :8000 # Or use different port mcpo --config mcpo-config.json --port 8001

New: On-View Functionality 🎨

What's New in Phase 1

The MCP server now includes comprehensive support for finding objects currently on physical exhibit at Smithsonian museums. This is a priority feature aligned with the Smithsonian's official API documentation.

Key Features

Find Exhibited Objects: Search for objects currently on display
Check Exhibition Status: Verify if specific objects are on view
Filter by Museum: Find what's on display at specific Smithsonian units
Exhibition Details: Access exhibition title and location information
Combined Filters: Mix on-view status with other search criteria

Usage Examples

Find all objects currently on view:

# Ask Claude: "What objects are currently on physical exhibit at the Smithsonian?" # Or with filters: "Show me paintings currently on display at the National Portrait Gallery"

Check if a specific object is on view:

# Ask Claude: "Is object edanmdm-nmah_1234567 currently on display?"

Combine with other filters:

# Ask Claude: "Find CC0 licensed objects currently on view with high-resolution images"

Tool Details

`get_objects_on_view`

Find objects currently on physical exhibit.

Parameters:

unit_code (optional): Filter by Smithsonian unit (e.g., "NMNH", "NPG")
limit: Maximum results (default: 20, max: 100)
offset: Pagination offset

Returns: Search results containing objects currently on exhibit

`check_object_on_view`

Check if a specific object is currently on display.

Parameters:

object_id: Unique identifier for the object

Returns: Object details including exhibition status

`search_collections` (enhanced)

Now includes on_view parameter for filtering.

New Parameter:

on_view (boolean): Filter objects by exhibition status
- True: Only objects currently on display
- False: Only objects not on display
- None: No filter (default)

Implementation Notes

This feature is based on the Smithsonian's onPhysicalExhibit metadata field, which indicates whether an object is currently accessible to the public in a physical exhibition. The implementation includes:

Full API alignment with EDAN metadata model v1.09
Fielded search support using onPhysicalExhibit:"Yes" queries
Comprehensive test coverage (15 unit tests)
Exhibition metadata extraction (title, location)
