"How to Query a Knowledge Graph Using an Ontology" matching MCP tools:
- Find how named entities like people, systems, or concepts connect in a channel's knowledge graph. Explore relationships between entities to understand their connections.Apache 2.0
- Match and retrieve knowledge graph nodes based on a text query against names, types, and observations.MIT
- Discover free query templates to learn what questions a knowledge graph can answer before spending credits on semantic queries.Apache 2.0
- Search BioPortal across an entire ontology to find standardized names and IRIs for terms, using a search string and ontology acronym.MIT
- Retrieve the hierarchical tree structure for an ontology class, showing its ancestor path and sibling nodes to understand its position in the ontology hierarchy.MIT
Matching MCP Servers
- AlicenseNot gradedqualityCmaintenanceA minimal MCP server with get_weather and create_ticket tools, used for testing MCP servers across protocol, unit, eval, transport, and auth layers.MIT
- AlicenseNot gradedqualityAmaintenanceEnables fast, targeted queries against an Obsidian vault knowledge graph using tools like search, neighbor traversal, and pathfinding, without needing to load the full graph into LLM context.2MIT
Matching MCP Connectors
Architecture-grounded query for AI agents. Governance constraints, evidence-linked answers.
The MCP for the beauty, cosmetics and personal care sector
- Explore a memory knowledge graph to find connected memories, hub nodes, or paths between memories. Query neighbors, hubs, or paths filtered by domain and relationship.-
- Search a paper's private knowledge graph assets to find figures or tables whose captions match a Lucene query, ranked by relevance.MIT
- Answer factual questions from a shared knowledge graph, grounded in evidence with citations. Abstains when the graph lacks knowledge.MIT
- List entities in the knowledge graph, optionally filtered by type, to obtain an overview or entity names for graph queries. Supports D3-compatible JSON output.MIT
- Generate an openCypher query from natural language descriptions for TigerGraph graphs. Specify graph name to get Cypher syntax wrapped in INTERPRET OPENCYPHER QUERY format.Apache 2.0
- Search persistent memory using semantic similarity to retrieve relevant memories and related knowledge graph facts.MIT
- Retrieve an overview of a knowledge graph volume, showing all entities and their relationships.MIT
- Query the knowledge graph to find entities connected to a given entity, revealing relationships and dependencies within specified depth.MIT
- Search the CodeLogic knowledge graph to retrieve code and data architecture dependencies. Use a text query or identity prefix, with optional scan space and view filters.Mozilla Public 2.0
- Add new observations to existing entities in a knowledge graph to enrich structured data with additional details.MIT
- Query project knowledge-graph context with tier filtering. Specify budget and pattern to get relevant evidence-anchored facts.MIT
- Explore how concepts in your notes connect by querying a knowledge graph of memories and wiki pages. Retrieve an entity's relations with source citations, or list top hub entities for orientation.MIT
- Explore the knowledge graph hierarchy from a starting node, viewing three levels of children to understand knowledge organization before searching or saving.MIT
- Persist entities and relations into a typed knowledge graph with ontology validation, provenance, and contradiction detection. Add source text and summary to support lexical recall.Apache 2.0
- Rank knowledge-graph nodes by importance using PageRank, optionally personalized by query, to surface top concepts for condensation, search ranking, and documentation sourcing.Apache 2.0
