Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Short links and trackable QR codes: editable after printing, device routing, scan stats.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Which app do you use?
Pick your app above. We remember it, so next time the button says “Install in …”.
This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.
Run this in your terminal
claude mcp add --transport http esyurl https://esyurl.fyi/mcp --header 'Authorization: your-value'Fill in the empty values before running it.
Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (0.2.0) reached the registry 30 days ago.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

Remote Desktop Commander: use files, terminal and processes on your own computers from any AI app.
Make sound with SuperCollider: synths, drums, chords, melodies and soundscapes over OSC.

A hosted MCP server that lets AI agents create and manage short links and QR codes with esyURL: shorten URLs, render styled QR codes, change where a printed or shared link points, route visitors by device or country, and read click and scan stats. The agent can sign itself up; no human account is needed.
https://esyurl.fyi/mcp (Streamable HTTP, stateless)Authorization: Bearer esy_...There is nothing to install or run: this repository describes the hosted server. The server itself is not open source.
An agent without a key can create its own account and get one, following esyurl.fyi/auth.md:
BASE=https://esyurl.fyi
REG=$(curl -s $BASE/agent/identity -H 'content-type: application/json' -d '{"type":"anonymous"}') KEY=$(curl -s $BASE/oauth2/token \ --data-urlencode grant_type=urn:ietf:params:oauth:grant-type:jwt-bearer \ --data-urlencode assertion=$(echo "$REG" | jq -r .identity_assertion) | jq -r .access_token) echo $KEY
Self-signed-up accounts get 100 links, 1000 once a human claims the account by email.
Claude Code:
claude mcp add --transport http esyurl https://esyurl.fyi/mcp \
--header "Authorization: Bearer esy_..."
Cursor, VS Code and other clients (.mcp.json style):
{
"mcpServers": { "esyurl": { "type": "http", "url": "https://esyurl.fyi/mcp", "headers": { "Authorization": "Bearer esy_..." } } } }
| Tool | What it does |
|---|---|
create_short_link | Shorten a URL, with an optional custom slug, QR style and redirect rules |
list_short_links | List your links, optionally by tag or group |
get_short_link | One link, with its groups and lifetime visit count |
update_short_link | Change where a link points, its QR style or rules, or pause it; the short URL and printed QR codes keep working |
delete_short_link | Delete a link |
test_redirect_rules | Check which destination a visitor would get (e.g. iPhone to the App Store, Android to Google Play) |
get_short_link_visits | Visits per day, split into QR scans, direct clicks and bots |
render_qr_code | A PNG QR code for a link (scans counted) or any text: module shapes, corner markers, colours, a logo or a photo |
create_group, list_groups, get_group, update_group, delete_group | Organise links into groups |
add_links_to_group, remove_link_from_group | Group membership |
get_group_visits | Combined visits for a group |
get_custom_domain, set_custom_domain, remove_custom_domain | Short links on your own domain |
Links, QR codes and stats are free. Self-signed-up accounts pay once per new custom domain, in USDC with x402; set_custom_domain returns the payment requirements first.
