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 | $0.00498 | $0.00498 |
| Opus 5 | $0.00249 | $0.00249 |
| Sonnet 5 | $0.00100 | $0.00100 |
| Haiku 4.5 | $0.00050 | $0.00050 |
Grade C, and why
marketplaces-mcp-ru AGENTS.md scanned grade C with 2 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 10d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
- `cabinets.json` — the local credential store (`~/.marketplace-mcp/`, chmod 600) Reads MCP configurationmediumAgent snooping
mcp.json carries server URLs and auth tokens; reading it lets a mod discover and abuse other integrations.
`.mcp.json` IS tracked on purpose — it is the secret-free plugin distribution Copies of this mod

Forbidden without explicit user confirmation
git push(confirm the diff first)- making a repo/issue/PR public with private context
- printing secrets:
cat .env,env,printenv,cat ~/.marketplace-mcp/cabinets.json - adding or changing MCP servers
- weakening the safety gate, auth, or input validation just to make code work
- installing packages suggested only from model memory (see below)
Dependency policy (trusted packages)
- Verify the package exists and is maintained before adding it.
- Prefer the standard library or already-present deps (
mcp,httpx,pyyaml). - CI runs
pip-auditand OSV scanning; do not introduce HIGH-severity advisories. - Never install hallucinated / typo-squat packages.
If a secret is exposed
Stop. Rotate/revoke it in the marketplace cabinet FIRST, then clean Git history. Marketplace keys are scoped and rotatable — rotation is the primary mitigation.
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.
