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 | $0.02236 | $0.02236 |
| Opus 5 | $0.01118 | $0.01118 |
| Sonnet 5 | $0.00447 | $0.00447 |
| Haiku 4.5 | $0.00224 | $0.00224 |
Grade A, and why
notion-mcp AGENTS.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 6d 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.

2. Security & Execution Model
2.1 Sandboxing (FULL_ACCESS)
- When
FULL_ACCESS=false(Default Sandbox):- All file and directory paths are strictly jailed within
FILES_ROOT(e.g.,./workspaceor custom configured path). - Path traversal attempts (
../, symlink escapes, absolute paths pointing outsideFILES_ROOT) are immediately rejected with an error. - Working directories (
cwd) forterminal_executedefault toFILES_ROOT.
- All file and directory paths are strictly jailed within
- When
FULL_ACCESS=true(Unrestricted Mode):- The agent has full access to the host filesystem with permissions of the host user running the server.
2.2 Limits and Buffers
MAX_OUTPUT_BYTES(default: 1 MB): Terminal output exceeding this limit is capped withtruncated: true.MAX_FILE_BYTES(default: 10 MB): File read/write operations exceeding this limit require offset pagination or are rejected.COMMAND_TIMEOUT_MS(default: 120,000 ms, max: 900,000 ms): Long running processes are automatically killed with their full process tree.
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.

notion-mcp AGENTS.md is an instructions file published in the GitHub repository Glebsky/notion-mcp (0 stars, last pushed 6d ago), licensed MIT. It adds 2,236 tokens to every session, about $0.0112 per session on Opus 5. 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 2026-08-31.
