VerifiedStreamable HTTPWeb executableFinance

Overview

AI-generated overview

Lets an assistant check a small online-business listing against 33 published red-flag rules, returning payback, asking multiple and flags.

What you can do
It exposes two tools. check_listing applies FirstPass Memo's 33 published red-flag rules to listing text or key numbers the user supplies for a business for sale, returning payback, asking multiple, flags and suggested seller questions. list_rules returns the 33 rules with code, title, group, severity, trigger condition and explainer link. It is served as a remote endpoint, so nothing is installed locally.
When to use it
Use it when a user is evaluating a small online business for sale (SaaS, content site, ecommerce, Amazon FBA, newsletter, app; roughly $10k-$150k) and wants a quick read on payback, asking multiple and red flags, plus questions to put to the seller.
Requirements
Network access to the remote endpoint. No environment variables, headers or authentication are declared. The user must supply the listing text or key numbers.
Before you install
Listing content and financial figures the user provides are sent to the third-party service FirstPass Memo. Output is a rule-based check, not investment advice; verify independently before any transaction.

Installation

In SourceWeft

  1. Open FirstPass Memo listing check in the dashboard and add it to a workspace.
  2. 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/com.firstpassmemo%2Flisting-check/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.

check_listing

Check a business-for-sale listing for red flags

Runs FirstPass Memo's 33 published red-flag rules on a small online-business listing (SaaS, content site, ecommerce, Amazon FBA, newsletter, app; roughly $10k-$150k) from Flippa, Empire Flippers, Acquire.com or any broker. Pass the listing text the user provides and/or the key numbers. Returns payback in months, the asking multiple vs comparable listings, every flag that fired (severity, why it matters, link to the rule) and questions to ask the seller. Screening only: not advice, a valuation or verification. Does not fetch URLs.

72% 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.
