ConceptNet

ConceptNet MCP — open multilingual knowledge graph of word/phrase relations: IsA, PartOf, UsedFor, HasA, RelatedTo, AtLocation, Causes, Synonym, Antonym, …. ~28M edges across 80+ languages. Keyless.

Part of Pipeworx — an MCP gateway connecting AI agents to 1394+ live data sources.

Tools

• lookup(term, lang?, limit?, offset?, only_rel?, end_node_lang?) — all edges touching a term
• query(rel?, start?, end?, node?, source?, limit?, offset?) — generic edge-query
• relatedness(node1, node2) — semantic-relatedness score for two terms

Common relations

• /r/IsA, /r/PartOf, /r/HasA, /r/UsedFor, /r/CapableOf, /r/AtLocation, /r/Causes, /r/Synonym, /r/Antonym, /r/RelatedTo, /r/HasContext, /r/MannerOf.

Data source

https://api.conceptnet.io/ — keyless, fair-use (~3600 req/hour).

Node URIs: /c/<lang>/<word> (e.g. /c/en/dog).

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "conceptnet": {
      "url": "https://gateway.pipeworx.io/conceptnet/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 1394+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Conceptnet data" })

The gateway picks the right tool and fills the arguments automatically.
