Read-only sourced engineering materials data: every value with unit, conditions and source.
Installation
Ajoutez ceci à la configuration MCP de votre client (Claude Desktop : claude_desktop_config.json ; Cursor : .cursor/mcp.json ; VS Code et les autres utilisent la même forme « mcpServers »).
claude mcp add --transport http materials 'https://spacemushroom.com/mcp'{
"mcpServers": {
"materials": {
"type": "http",
"url": "https://spacemushroom.com/mcp"

Sommaire
Space Mushroom MCP server
A free, read-only Model Context Protocol server for engineering materials. Every number it returns comes with its unit, the conditions it was measured under, the method and the source it was read from, so an AI assistant can quote a value and prove where it came from.
- Endpoint (Streamable HTTP):
https://spacemushroom.com/mcp - No API key, no sign-in. Read-only.
- Data: about 600 material profiles (metals, polymers, ceramics, composites, semiconductors, thermal protection, shielding, regolith and more, with a focus on space materials), licensed CC BY 4.0.
- Docs and setup page: https://spacemushroom.com/mcp-server/
- Website: https://spacemushroom.com · Open dataset: Zenodo, Hugging Face, GitHub
Tools
| Tool | What it does |
|---|---|
find_materials | Requirements in, candidates out. Each material gets pass, fail or unknown, with the evidence |
search_materials | Find materials by name, abbreviation or formula |
get_material | The sourced record of one material: values, conditions, uses, hazards, failure modes, corrosion, supply |
compare | Line several materials up on one property, each value with its conditions and source |
list_properties | Property names in use, with canonical units |
list_claims | Every current sourced value for a material, with an evidence level and a claim id |
prove_claim | Everything behind one value: as printed, converted, conditions, and where in each source |
what_is_missing | Which properties have sourced data and which have none (not covered yet, not "safe") |
resolve_designation | Which material a code names: UNS, EN, DIN, JIS, AISI/SAE, ASTM, AMS or a trade name |
search_sources | Full-text search over short quoted passages from the sources |
get_term | Plain-language definition of a technical term |
Add it to a client
Claude Desktop, Cursor, VS Code and other clients that accept a remote server:
{
"mcpServers": {
"space-mushroom": { "url": "https://spacemushroom.com/mcp" }
}
}Claude Code:
claude mcp add --transport http space-mushroom https://spacemushroom.com/mcpExample questions
- "Which stainless steels have a sourced minimum yield strength above 400 MPa, and what are the conditions?"
- "What material is UNS S31600 and what is its density, with the source?"
- "Compare PEEK, PEI and PPS on continuous service temperature."
- "What does Space Mushroom have no data on for Ti-6Al-4V?"
How accurate is it?
Profiles are drafted with AI assistance from cited sources and then checked automatically: every value must be found in its cited source, and every designation must be printed there. Values marked ai_checked were re-read by an AI assistant, not a person. See the methodology and editorial policy. Check the source before using a value in a safety-critical design.

Questions fréquentes
Qu'est-ce que com.spacemushroom/materials ?
Read-only sourced engineering materials data: every value with unit, conditions and source.
Comment installer com.spacemushroom/materials ?
Il fonctionne comme serveur distant. Dans Claude Code : claude mcp add --transport http materials 'https://spacemushroom.com/mcp'. Pour les autres clients, collez la configuration JSON de cette page dans leurs réglages MCP.
Faut-il une clé API pour com.spacemushroom/materials ?
Son entrée au registre n'indique aucune clé ni secret obligatoire. Certaines fonctions peuvent tout de même demander un compte auprès du service auquel il se connecte.
com.spacemushroom/materials est-il open source ?
Son code est public sur GitHub, mais le dépôt ne déclare pas de licence standard.
Qui maintient com.spacemushroom/materials ?
Il est publié par simulsarker007. AI.tn le référence sans le maintenir ni le recommander.
Issu du registre MCP officiel. Être listé n'est pas une recommandation : vérifiez le code et les permissions d'un serveur avant de lui donner accès à vos données.
