Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

linkwarden-bookmarks scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Linkwarden bookmarks

Pairs with the linkwarden-mcp MCP server.

Discovery first

  1. Call list_resources.
  2. Trust its read_only, write_scopes, delete_scopes, effective_write_scopes, and boundary.
  3. Prefer workflow tools (smart_save_link, triage_links, get_sorting_dashboard) over raw field edits when sorting or filing.

Boundary

  • Empty scopes → read-only tool set (18 tools including list_resources).
  • Mutations need LINKWARDEN_MCP_WRITE_SCOPES (create/update) and/or LINKWARDEN_MCP_DELETE_SCOPES (delete). Delete is never implied by write.
  • Recommended write scopes: links,collections (not all domains).
  • Valid domains: links, collections, tags, plus raw escape hatch.
  • raw expands effective write scopes to all domain scopes.
  • Never attempt tokens, session, auth, users (except GET /api/v1/users/me), migration, or whole-instance preservation endpoints.

Config

  • LINKWARDEN_API_URL — instance base URL (no /api/v1 suffix)
  • LINKWARDEN_API_KEY — Bearer access token; never echo
  • Scope CSVs must match between local .env and the MCP host env block
  • If a tool says Linkwarden is not reachable: tell the user to check URL/key and that the instance is up. Do not treat it as an MCP server crash.

Precondition responses

When a tool returns setup guidance or a structured failure the user must fix:

  1. Relay each item's how_to_create (or equivalent guidance) text to the user verbatim.
  2. Stop. Do not invent a workaround or skip setup steps.

Also stop and relay verbatim for:

  • Unknown / ambiguous collection or tag names (UnknownNameError / AmbiguousNameError) — list collections/tags first, or use an id.
  • BulkCapExceeded — shrink the batch or raise LINKWARDEN_MAX_BULK.
  • Dry-run payloads (dry_run: true) — do not apply until the user confirms dry_run=false.
  • delete_collection with needs_user_input: true — relay question and options verbatim, ask the user how to dispose of links (delete / move / cancel), then re-call with on_links (and move_to when moving). Do not invent a default disposition.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
