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 opcastil11 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 assistant discover, evaluate and compare SaaS APIs using agent-verified scores and metrics.

What you can do: Discover SaaS APIs the assistant can look up and explore through the server's tools, which are not itemized in the listing. Evaluate APIs using agent-verified scores and metrics. Compare SaaS APIs side by side to support selection decisions. Discovery is described as free and does not require a key.
When to use it: Useful when you are choosing between SaaS APIs or vendors and want an assistant to surface and compare them with scored, agent-verified metrics rather than ad hoc opinions.
Requirements: Runs as a local process on the user's machine, installed from the npm package mcp-prowl over stdio, so Node.js is needed. An optional Prowl agent key is supplied through the PROWL_AGENT_KEY environment variable for authenticated requests; discovery works without it. Desktop only.

Before you install

The optional PROWL_AGENT_KEY is a secret credential; keep it out of shared configuration and logs. Scores and metrics come from the provider and should be treated as third-party claims rather than independent verification.

Installation

In SourceWeft

Open Mcp Prowl 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.
