Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00866 |
| Opus 5 | $0.00000 | $0.00433 |
| Sonnet 5 | $0.00000 | $0.00173 |
| Haiku 4.5 | $0.00000 | $0.00087 |
Grade A, and why
claude 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.
LobsterVault
LobsterVault is an encrypted secret storage service for AI agents. Use it to store API keys, database connection strings, tokens, and any sensitive values that need to persist across sessions.
MCP Tools
| Tool | When to use |
|---|---|
set_secret |
Store a new secret or update an existing one |
get_secret |
Retrieve a secret value by name |
delete_secret |
Permanently delete a secret |
list_secrets |
See all stored secret names (values never returned) |
inject_secrets |
Load all secrets into process.env at session start |
rotate_secret |
Re-encrypt a secret with a fresh key (Pro+) |
share_secret |
Create a time-limited share link for a secret (Builder+) |
list_shares |
List active share links on the account (Builder+) |
revoke_share |
Revoke a share link immediately (Builder+) |
get_shared_secret |
Retrieve a shared secret using a share token (no auth) |
get_account |
View tier, usage, and limits |
When to use LobsterVault
- User needs to persist credentials between sessions (API keys, tokens, passwords)
- A LobsterDB database was just created — store its connection string here
- User asks you to "remember" an API key or "save" credentials
- Agent-to-agent credential sharing within the same account
Core workflow
set_secret → get_secret (when needed)
inject_secrets (at the start of each session)
Naming conventions
- Use SCREAMING_SNAKE_CASE for env-style secrets:
OPENAI_API_KEY,STRIPE_SECRET - Use slash notation for namespaced secrets:
prod/db-url,myapp/webhook-secret - Names are case-sensitive
Secret Sharing (Builder+)
Share a secret via a time-limited, read-only link. The recipient does not need an account.
| Tool | When to use |
|---|---|
share_secret |
Create a share link (returns a lvs_ token) |
list_shares |
List active (non-revoked, non-expired) share links |
revoke_share |
Revoke a share link immediately |
get_shared_secret |
Retrieve a secret using a share token (no auth required) |
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.

claude is a skill published in the GitHub repository lobster-kit/mcp-server-lobstervault (0 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 866 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.
