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 | $0.00286 |
| Opus 5 | $0.00000 | $0.00143 |
| Sonnet 5 | $0.00000 | $0.00057 |
| Haiku 4.5 | $0.00000 | $0.00029 |
Grade A, and why
vault-ipc 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
Vault IPC Socket
Unified Unix socket replacing the old two-socket model (x402-signer.sock + openmm-creds.sock).
Socket
- Path:
/tmp/openmm.sock(override viaOPENMM_SOCKETenv var) - Permissions: mode
0600(owner-only) - Started by:
openmm serveafter interactive vault unlock
Message Protocol
JSON messages over the socket, dispatched by type:
{ "type": "sign_payment", "payload": {} }
→ { "signature": "0x..." }
{ "type": "get_credentials", "exchange": "mexc" }
→ { "apiKey": "...", "secret": "..." }
{ "type": "ping" }
→ { "status": "ok", "wallet": "0x...", "exchanges": ["mexc", "gateio"] }
signAndWipe Pattern
Private key is decrypted inline, used once, and goes out of scope immediately. It is NEVER held in a long-lived variable.
Security Invariants
- Password typed once interactively in terminal — never passed as flag or env var
- Socket file = proof of authentication (exists → vault is unlocked)
- Stale socket cleaned up on startup, deleted on shutdown
- MCP server connects via socket — does NOT hold vault data in its own memory
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.

vault-ipc is a skill published in the GitHub repository QBT-Labs/openmm-mcp (3 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 286 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 2026-08-31.
