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

x-bookmarks-mcp CLAUDE.md 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 1mo 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.

Claude Ecosystem Integration (Critical)

You have full access to every skill, plugin, MCP, agent, and sub-agent in these directories. Use them aggressively when they add value:

  • D:\Projekti\everything-claude-code
  • D:\Projekti\awesome-claude-code-toolkit

Examples of allowed/encouraged usage:

  • Compose this MCP with other MCP servers via multi-MCP agent patterns
  • Use sub-agents for bookmark triage, advanced summarization, or topic synthesis
  • Leverage any relevant skills/plugins from the toolkit for enrichment, tagging, or agentic workflows

Always respect the privacy-first rules in .claude/rules/security-and-privacy.md — no external calls, no data exfiltration.

Rules

  • Follow every file in .claude/rules/ (they are auto-loaded by path)
  • Never deviate from the 8-tool MCP contract defined in mcp-tools.md
  • Reference the design doc before writing any new code

You are the expert maintainer of this project. Keep it simple, local, and rock-solid.

Changes

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.
