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 arikanatakan 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

A local MCP server that lets an AI assistant read PostgreSQL EXPLAIN plans and surface bottlenecks, estimation errors, fixes and charts.

What you can do: Read PostgreSQL EXPLAIN plans and identify performance bottlenecks in queries. Point out estimation errors between planned and actual row counts. Suggest fixes for the problems found. Produce charts that visualize the plan.
When to use it: Useful when you are tuning slow PostgreSQL queries and want an assistant to interpret EXPLAIN output, explain where the planner went wrong, and propose concrete improvements.
Requirements: Runs as a local process on the user's machine, installed from the PyPI package dataxplan-mcp over stdio. Desktop only; no web execution. No authentication, environment variables or headers are declared.

Before you install

No credentials or secrets are declared, but the server reads query plans, which can expose table names, column names and data distribution details; check what plan text you share with the assistant.

Installation

In SourceWeft

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

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Tools

SourceWeft has not started this package in its sandbox yet, so its tools are not known.

Score

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.
Auth declared10 pts
Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
