In-depth architectural comparison of the Disney and Oqmd MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
Disney
Databases · Local stdio
Quality: 41/100 (Fair) | Auth: No auth required
Oqmd
Databases · Local stdio
Quality: 43/100 (Fair) | Auth: No auth required
Verdict Summary: Choose Disney if you need specialized Databases tools running via a local process. Choose Oqmd if your workspace requires Databases integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
D
Choose Disney when:
You need dedicated capabilities in the Databases domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Search the Disney character database by name (e.g. "Mickey Mouse", "Elsa", "Stitch"). Returns matching characters with their film, TV-show, video-game and theme-park-attraction appearances plus an image URL. Matching is exact-ish on the name field.
get_character
Fetch a single Disney character by numeric id (_id). Returns the full record: films, short films, TV shows, video games, park attractions, allies, enemies, image URL and source URL.
list_characters
List/paginate the Disney character database. Returns a page of characters (id, name, image URL) plus total count and total page count. Useful for browsing the full catalog.
Oqmd Tools (3)
search_materials
Search the Open Quantum Materials Database for DFT-computed inorganic materials by composition and/or constituent elements, with optional band-gap and thermodynamic-stability filters. Returns formation energy (eV/atom), energy above the convex hull (stability), band gap, space group, and prototype.…
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Disney is categorized under Databases and uses a local stdio subprocess. In contrast, Oqmd belongs to Databases using local stdio subprocess. Select Disney when you need capabilities focused on databases and Oqmd when you require tools for databases.
Fetch a single OQMD material by its entry_id (e.g. 16525 = the Pbcn polymorph of Fe2O3). Returns formation energy (eV/atom), stability above hull, band gap, space group, prototype, cell volume, atom/element counts, ICSD id, and generic composition. Keyless.
stable_phases
List the ground-state (on-hull) phases of a chemical system — the thermodynamically stable compounds in OQMD for a given set of elements. e.g. "Fe-O" returns FeO, Fe2O3, Fe3O4. Restricts to materials made ONLY of the given elements with stability <= ~0 (on the convex hull). Keyless.
