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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.03880 | $0.03880 |
| Opus 5 | $0.01940 | $0.01940 |
| Sonnet 5 | $0.00776 | $0.00776 |
| Haiku 4.5 | $0.00388 | $0.00388 |
Grade A, and why
jetbrains-debugger-mcp-plugin CLAUDE.md scanned grade A with 1 finding 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 8d 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.

Expected in a hook, worth knowing in a rule or an instructions file.
the blocklist is JVM-specific, so `os.system`, `require('child_process')` and similar pass How it starts

JetBrains Debugger MCP Plugin
This plugin exposes JetBrains IDE debugger capabilities through MCP (Model Context Protocol), enabling AI agents to programmatically debug applications.
Quick Start
IMPORTANT: When debugging, prefer using jetbrains-debugger MCP tools to interact with the IDE debugger.
Typical Debugging Workflow
- Discover configurations:
list_run_configurationsto see available run/debug configs - Start debugging:
start_debug_sessionwith a configuration that hascan_debug: true - Set breakpoints:
set_breakpointat locations of interest - Resume and wait:
resume_executionthenwait_for_pausewith a timeout to block until a breakpoint is hit - Inspect state:
wait_for_pausereturns variables, stack trace, and source context automatically. Useget_debug_session_statusif you need to re-inspect without waiting. - Evaluate expressions:
evaluate_expressionto test hypotheses - Step through code:
step_over,step_into,step_outas needed - Repeat steps 5-7 until the issue is found

Wait for session to pause (breakpoint, exception, manual). Returns full status. |
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.

jetbrains-debugger-mcp-plugin CLAUDE.md is an instructions file published in the GitHub repository hechtcarmel/jetbrains-debugger-mcp-plugin (104 stars, last pushed 6d ago), licensed MIT. It adds 3,880 tokens to every session, about $0.0194 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
