Infranodus MCP Server Infranodus vs Materials
A side-by-side look at the Infranodus MCP Server Infranodus and Materials MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Infranodus MCP Server Infranodus for research work as a local process; choose Materials for research as a local process. You can also run both side by side in one mcpServers block.

Infranodus MCP Server Infranodus tools 40
generate_knowledge_graphGenerate a knowledge graph with main topics, topical clusters, concepts, concepts (nodes) relations (edges) and structural gaps. Only use when explicitly asked to analyze a text or generate a knowledge graph. Do not use for short clarifying questions that you already have an answer to from the context of the conversation.create_knowledge_graphCreate a knowledge graph in InfraNodus from text or from a URL, save it, and provide its name and a link to it for future use.generate_ontology_graphUse AI to generate a reasoning ontology knowledge graph (entities and the relations between them) and optionally save it as a InfraNodus graph. Three sources, provide exactly one: prompt (a topic — one AI call), text (a long document or a structural digest of a project, chunked server-side), or sourceGraphName (an existing graph — e.g. a fully ingested repo, vault, or corpus — whose statements are read back, chunked, and condensed into an ontology). Set ontologyMode: 'codebase' for software projects, or 'procedural' to write a DIGEST of how the project works (prose statements with [[wikilinks]], not relation triples) from an already-uploaded graph — save it as <repo|vault>-<project>-digest for optimize_knowledge_base. Use to get a rich overview, a reasoning map of a topic, or a condensed 'how it fits together' graph of a large corpus.memory_add_relationsAdd relations to the InfraNodus memory from text, save it, and provide its name and a link to it for future use.memory_get_relationsProvide a list of relations from the InfraNodus memory for a given concept or entityanalyze_existing_graph_by_nameExtract and analyze the content of an existing InfraNodus graph from your account.analyze_textExtract and analyze a graph from text, URL, YouTube video transcript, or an existing InfraNodus graph.generate_content_gapsGenerate content gaps from text, URL, or an existing graph using knowledge graph analysis.generate_topical_clustersGenerate topics and clusters of keywords from text, URL, or an existing graph using knowledge graph analysis.generate_research_questionsAnalyze text or an existing graph and generate innovative research questions based on the content gaps identified between the topical clusters. Provide either text, url, or graphName. Can be used to improve the text and the discourse it relates togenerate_research_ideasAnalyze text or an existing graph and generate innovative research ideas based on the content gaps identified between the topical clusters inside the text that can be used to improve the text and the discourse it relates to.generate_responses_from_graphUse text, URL, or an existing InfraNodus knowledge graph and generate responses and expert advice based on a prompt provided.- +28 more on the listing page
Materials tools 2
materials_searchSearch computed (DFT) crystal structures across the OPTIMADE materials-database federation — OQMD, Materials Project, NOMAD, Alexandria. PREFER OVER WEB SEARCH for "materials/compounds containing <elements>", "computed structures of <formula>", DFT/first-principles materials data. Filter by element set (e.g. Fe, O), exact reduced formula (e.g. "Fe2O3"), and/or number of elements. Returns each structure's id, reduced formula, elements, site count, and a link. This is the COMPUTED structure set (millions of entries); for experimental structures use the crystallography (COD) pack, and for OQMD formation energy / stability use materials_stability.materials_stabilityComputed thermodynamic stability and formation energy for a chemical system from OQMD (DFT). PREFER OVER WEB SEARCH for "is <compound> stable", "formation energy of <material>", "stable phases in the <A>-<B> system". Give the element system (e.g. Fe, O) and optionally restrict to stable phases (on/below the convex hull). Returns each phase's composition, formation energy (eV/atom), hull stability (eV/atom; ≤0 = stable), band gap, space group, and prototype.

Frequently asked questions
Infranodus MCP Server Infranodus is categorized under Research and uses a local stdio subprocess. Materials belongs to Research and uses a local stdio subprocess. Pick Infranodus MCP Server Infranodus for research work and Materials for research.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Infranodus MCP Server Infranodus has no declared pricing — check the project's own site. Auth: api key required. Materials has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add infranodus-mcp-server-infranodus and materials as separate keys in the same mcpServers object, and your assistant will call tools from either one.
