Use LinkCrypt with Claude

Give Claude (Claude Code, Claude.ai, or any HTTP-capable agent) read/write access to your personal link library — search saved articles, save new URLs with tags, and keep research in sync.

What you can do

  • Search your library during a coding or research session (GET /search, GET /links)
  • Save links Claude surfaces with suggested tags (POST /links)
  • Add or adjust tags without opening the web app (POST /links/:id/tags)
  • Pull high-level stats or an AI digest of your saves (GET /analyze/stats, POST /analyze/digest)

Setup

  1. Create a LinkCrypt account if you don't have one.
  2. Open Preferences, generate an API key, and copy it once (it starts with lc_).
  3. In Claude Code: add a project skill (or paste into your agent instructions) using the template below. Replace YOUR_API_KEY with your key — never commit real keys to git.
  4. Full endpoint list: API reference.

Claude skill template (SKILL.md)

Save as SKILL.md in your Claude Code skills folder, or paste the body into custom instructions.

# LinkCrypt

**Base URL:** https://getlinkcrypt.com/api/v1
**Auth:** `Authorization: Bearer YOUR_API_KEY`

## Guardrail
Never call `DELETE /links/:id` unless the user explicitly asks to permanently delete a saved link.

## Common operations
- `GET /search?q=...` — full-text search (title, description, domain, page content)
- `GET /links?tags=ai,python&limit=50` — AND filter by tags
- `GET /links/:id` — one link + tags
- `POST /links` — body `{ "url", "title?", "description?", "tags"? }`
- `PATCH /links/:id` — body `{ "title?", "url?", "description?", "is_favorite?" }`
- `GET /tags` — all tags + counts
- `POST /links/:id/tags` — body `{ "name" }`
- `GET /analyze/stats` — library overview

Use `curl` or any HTTP client. Parse JSON responses; errors look like `{ "error": "..." }`.

Example prompts

  • “Search my LinkCrypt library for anything saved about Rust async and summarize the top 5 sources.”
  • “Save https://example.com/article to my library with tags research and rust.”
  • “What tags do I use most? Use GET /analyze/stats.”
