mcp-json

JSON tools MCP.

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

Tools

Tool	Description
`validate_json`	Validate a JSON string (keyless, offline). Returns whether it is valid and, if not, the error message and the character position.
`format_json`	Pretty-print or minify a JSON string. `indent` sets spaces (default 2); pass 0 to minify to a single line. Keyless, offline.
`query_json`	Extract a value from JSON at a path using dot/bracket notation, e.g. "user.addresses[0].city". Keyless, offline.

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

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

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

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

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

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

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