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 | $0.00000 | $0.00181 |
| Opus 5 | $0.00000 | $0.00090 |
| Sonnet 5 | $0.00000 | $0.00036 |
| Haiku 4.5 | $0.00000 | $0.00018 |
Grade A, and why
mcp-session-checkpoint 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.
What it actually says
MCP Session Checkpoint
Create a named checkpoint in the current session for later restoration.
Instructions
- Parse the user's input for a checkpoint name
- Create the checkpoint using
mcp__openrouter-agents__checkpointwith:name: The checkpoint name (use a descriptive name if user doesn't provide one)sessionId: "default" (unless user specifies)
- Confirm the checkpoint was created
- Show current session state using
mcp__openrouter-agents__session_state
Use Cases
- Before making major changes: "before-refactor"
- After successful completion: "working-v1"
- At investigation milestones: "found-root-cause"
Example Usage
/mcp-session-checkpoint before-refactor /mcp-session-checkpoint "working state v2"

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.

mcp-session-checkpoint is a command published in the GitHub repository wheattoast11/openrouter-deep-research-mcp (55 stars, last pushed 10d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 181 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
