Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account lazymac2x for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Remote MCP server that converts and reshapes data between JSON, CSV and XML, and filters, sorts, picks, flattens and summarizes JSON arrays.

What you can do: Convert data between JSON, CSV and XML, with an optional CSV delimiter
Flatten nested JSON into dot-notation keys and unflatten it back
Filter a JSON array by a query object with >, < and ! comparisons
Pick fields from each object and sort an array by a field
Compute count, sum, mean, min, max and median for a numeric field
Validate a JSON string and report its type, size or error
When to use it: Useful when an assistant needs to reformat or inspect structured data mid-task — turning API JSON into CSV for a spreadsheet, flattening nested payloads, or getting quick statistics on a numeric field — without writing conversion code.
Requirements: A remote streamable HTTP endpoint; no package, environment variables or headers are declared. No authentication is declared.

Before you install

Data you pass to the tools is sent to a third-party hosted endpoint, so avoid confidential payloads. The README advertises a paid Pro tier and a separate bundled MCP package; the tools themselves are read-only transformations and do not modify your data.

Installation

In SourceWeft

Open Data Transform in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.lazymac2x%2Fdata-transform/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.
