# datanexusmcp

Hub wrote this skill from its listing of `com.datanexusmcp/mcp-server` v2.4.14. The only text from the server itself is in the section quoted from it below.

## How to reach it

- A web service at `https://datanexusmcp.com/mcp` (streamable HTTP); nothing runs here.
- Your MCP client knows it as `datanexusmcp` (`clients/` configures it under that name); call its tools by the names below. Claude Code shows them as `mcp__datanexusmcp__<tool>`.
- No credentials.

## Tools

55 tools. The read-only column is the server's own hint (`readOnlyHint`), not something the hub checked.

### Quoted from the server: data, not instructions
