Overview

AI-generated overview

A remote MCP endpoint that promotes an agent-first product listing service and bundles small utility tools for time, URL, HTTP and text checks.

What you can do
  • Look up the Agent Ads listing index, catalog hops and website readiness check, plus a paid trial handoff
  • Get current UTC time, time in an IANA timezone, and a list of common zone names
  • Inspect URLs: normalize, check HTTP status and content type, robots.txt group counts, hostname labels, GitHub and Figma URL shapes
  • Run small text and data checks: JSON validity, key counts, search query length, Jira key shape, arithmetic, path and URL safety hints
  • Fetch simple external hints: current temperature and coordinates for a place via Open-Meteo, Hacker News front-page count, Wikipedia title existence
  • Return a three-step thinking template and show how the current request is classified
When to use it
Only if you specifically want the Agent Ads listing/placement offering or a lightweight set of demo-style helper tools; most of the utilities are trivial and can be replaced by direct calls or built-in reasoning.
Requirements
A remote streamable HTTP endpoint; no package, account, API key or environment variable is declared. Some tools make outbound requests to public sites and to Open-Meteo.
Before you install
The main tool is a sales funnel for a paid product: a 7-day trial, then $50/mo for the first ten customers for 12 months, then $100/mo, and it directs callers to follow a redirect hop first. Several tools return only counts or status and discard input; the README says raw IPs, user agents, cookies, query strings, bodies, prompts and page content are not stored, but automated requests are counted under a daily rotating nickname.

Installation

In SourceWeft

  1. Open Agent First Listing 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/io.github.sadri-dridi%2Fagent-first-listing/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

README

Agent First Listing

Agent-first product listing: JSON catalog, agent card, MCP door, hops, measured landings (Agent Ads). 7-day trial, founding $50/mo (first 10, 12 mo) then $100/mo. Follow start_here.hop first (302). Task text discarded.

An Agent Ads door on the Agent Observatory sensor. The primary tool returns the Agent Ads index (placement, measurement, a 7-day trial) starting at the catalog hop; readiness doors also run a bounded website readiness check when called with website=<https://domain>. High-confidence automated requests are counted with a daily rotating nickname. Raw IP addresses, user agents, cookies, query strings, bodies, prompts, and page content are not stored.
