Overview

AI-generated overview

Lets an assistant search nine platforms to find existing products similar to a user's idea.

What you can do
Prexist is a local MCP server that gives an assistant a way to search across nine platforms for existing products that resemble a given idea. The registry description states its purpose as searching those platforms to find similar products. No individual tools are listed in the manifest, so the exact tool names and parameters are not documented here.
When to use it
Useful when someone wants a quick check of whether an idea already exists as a product before building or launching it. It fits early research and competitive discovery rather than ongoing product management.
Requirements
Runs as a local process on the user's machine, installed from the npm package prexist over stdio, so Node.js is needed. Desktop only; no web executable. An optional environment variable PREXIST_API_URL can override the API base URL, and an optional secret SKILLS_DIRECTORY_API_KEY is used for skillsdirectory.com; if it is not set, that source is skipped.
Before you install
The server sends the user's idea text to external platforms to perform searches, so avoid submitting confidential or unreleased concepts. It can read the secret SKILLS_DIRECTORY_API_KEY from the environment; treat that key as sensitive. Setting PREXIST_API_URL points the server at a non-default endpoint, which changes where requests go.

Installation

In SourceWeft

  1. Open Prexist in the dashboard and add it to a workspace.
  2. 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.

Other MCP clients

Follow the launch instructions in the repository.

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.

  • Reached in the last 30 days25 pts

    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.
