Linkwarden MCP
This MCP server connects to a Linkwarden instance, enabling semantic search, filtering, and management of bookmarks through natural language.
README
Linkwarden MCP
An MCP server that exposes a Linkwarden bookmark collection as a tool set, running as a stateful agent on Cloudflare Workers. Point an MCP client (Claude, etc.) at the deployed endpoint and it can browse, search, filter, create, and archive links directly against your own Linkwarden instance.
How it works
Every tool call goes straight to the Linkwarden REST API on your live instance — there's no index, cache, or background sync involved.
MCP client ──HTTP/SSE──► Worker (/mcp) ──► LinkwardenMCP (Durable Object)
│
LINKWARDEN_URL + LINKWARDEN_TOKEN → Linkwarden API
LinkwardenMCP is a McpAgent hosted on a Durable Object.

Setup
npm install
wrangler secret put LINKWARDEN_URL # base URL of your Linkwarden instance
wrangler secret put LINKWARDEN_TOKEN # Linkwarden API token
See CLAUDE.md for the full architecture and binding reference.
Development
npm run dev # wrangler dev — local development with hot reload
npm run test # vitest run
npm run typecheck # tsc --noEmit
Deploy
npm run deploy
Or connect this repository to a Cloudflare Worker for git-based deploys. Either way,
LINKWARDEN_TOKEN must be set as a Wrangler secret in the target environment — it is never stored
in the repo.
