Use Afterwren MCP with VS Code (GitHub Copilot)

Retired-API replacements: Clearbit-style company autocomplete, logos, profiles; geocoding; books.

Remote MCP server (Streamable HTTP), nothing to install. Free: 100 free calls/day · Paid: $5 pack; $19/mo; x402 $0.002/call

Set it up

Create .vscode/mcp.json in your workspace (or run MCP: Add Server from the Command Palette).
Paste the configuration and save; a Start button appears above the server entry.
Start the server, then open Copilot Chat in Agent mode and check the tools list.
Ask a question the tools can answer and approve the tool call.

Add to .vscode/mcp.json:

{
  "servers": {
    "afterwren": {
      "type": "http",
      "url": "https://afterwren.cybermaxtools.com/mcp?via=use-with-vs-code"
    }
  }
}

With a paid key:

{
  "inputs": [
    {
      "type": "promptString",
      "id": "cybermax-key",
      "description": "CyberMax API key",
      "password": true
    }
  ],
  "servers": {
    "afterwren": {
      "type": "http",
      "url": "https://afterwren.cybermaxtools.com/mcp?via=use-with-vs-code",
      "headers": {
        "x-api-key": "${input:cybermax-key}"
      }
    }
  }
}

VS Code asks for the key the first time the server starts and stores it securely; it never sits in the file.

Where it goes:

.vscode/mcp.json in your workspace (VS Code format, top-level "servers")
or the portable .mcp.json at the workspace root (top-level "mcpServers")

Tools you get

Endpoint checked 2026-10-09: https://afterwren.cybermaxtools.com/mcp answered an MCP initialize (protocol 2025-06-18) and tools/list with 7 tools, all marked read-only. No key was used and no tool was called.

Tool	What it does	Required inputs
`company_suggest`	Company name or prefix to a list of {name, domain, logo, description}, best-known first (Clearbit Autocomplete replacement).	`query`
`company_logo`	The best logo/icon URL for a domain from the company's own site, with alternatives (Clearbit Logo replacement).	`domain`
`company_profile`	Name, description, logo, social links, email provider (MX/SPF) and Wikidata facts (founded, HQ, industry, employees, ticker) for a domain.	`domain`
`geocode`	Address or place to lat/lng with city, state, postal, country; US results include county, tract and block FIPS.	`q`
`reverse_geocode`	Coordinates to the nearest address and, in the US, county/tract/block FIPS.	`lat`, `lng`
`book_search`	Books by title/author or ISBN: authors, year, ISBNs, pages, rating, cover (Goodreads API replacement, Open Library data).	none
`encyclopedia_search`	Wikipedia full-text search: titles, URLs and snippets (for grounding after the Bing Search API retirement).	`q`

Test the endpoint from a terminal

This lists the tools without a key and without calling any of them:

curl -s https://afterwren.cybermaxtools.com/mcp \
  -H 'content-type: application/json' \
  -H 'accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

If it does not work

In .vscode/mcp.json the key is "servers" and "type": "http" is required.
The docs note the Add Server flow now recommends the portable .mcp.json, which uses "mcpServers" instead; both formats are documented.
The free tier has a daily limit (see the pricing line above); a paid key raises it.
