Linkly MCP Server

Linkly MCP Server

Official Model Context Protocol (MCP) server for Linkly — the URL shortener and link management platform.

This repository powers the hosted MCP server at https://mcp.linklyhq.com. That is the only supported way to connect an AI assistant to Linkly via MCP. See https://linklyhq.com/support/mcp-server for setup instructions.

⚠️ The linkly-mcp-server npm package is deprecated. The self-hosted / API-key flow is no longer maintained. All users should migrate to the hosted server — it uses OAuth 2.1 with PKCE, requires no API keys or local install, and always runs the latest tool set. The npm package will continue to exist on the registry for backwards compatibility but will not receive new tools or bug fixes, and may be unpublished in the future.

Publishing to the MCP Registry (maintainers)

The server.json at the repo root is the official MCP Registry manifest for the com.linklyhq/linkly server. It is remote-only: it points clients at the hosted server and intentionally ships no package (the deprecated npm distribution was dropped in v2.0.0).

Publishing requires DNS access to linklyhq.com — the com.linklyhq namespace is verified via a DNS TXT record on the domain apex:

# 1. Generate an Ed25519 key + TXT record (macOS: use openssl@3; system LibreSSL lacks Ed25519)
openssl genpkey -algorithm Ed25519 -out key.pem
PUBLIC_KEY="$(openssl pkey -in key.pem -pubout -outform DER | tail -c 32 | base64)"
echo "linklyhq.com. IN TXT \"v=MCPv1; k=ed25519; p=${PUBLIC_KEY}\""   # add at the APEX of linklyhq.com

# 2. Authenticate the namespace + publish
PRIVATE_KEY="$(openssl pkey -in key.pem -noout -text | grep -A3 'priv:' | tail -n +2 | tr -d ' :\n')"
mcp-publisher login dns --domain linklyhq.com --private-key "$PRIVATE_KEY"
mcp-publisher publish

See the registry authentication guide for details.

Updating the ChatGPT app (maintainers)

chatgpt-app-submission.json is the OpenAI Apps SDK submission import — it pre-fills the per-tool annotations and the three safety justifications (read-only / open-world / destructive) for all 25 tools, so they don't have to be typed by hand in the dashboard.

OpenAI freezes a metadata snapshot at publish time and does not auto-detect MCP changes, so after deploying server changes you publish a new version:

1. Deploy the worker (push to the connected branch / wrangler deploy).
2. Platform dashboard → the Linkly app → create a new draft version (keep the same MCP URL https://mcp.linklyhq.com).
3. In the MCP section, click Scan Tools to re-read the live tool list + annotations.
4. Drag chatgpt-app-submission.json onto the form (top of the page) to fill the justifications.
5. Review Testing, then Submit. The published version keeps running against the live server until the new one is approved.

Keep this file in sync with the worker whenever tools are added/removed or their readOnlyHint/destructiveHint change. The destructive flag is true only for the 5 genuinely destructive tools (delete_link, delete_domain, batchDeleteLinks, unsubscribe_webhook, unsubscribe_link_webhook); creates/updates/subscribes are additive (false).
