What it offers — 7 tools · Developer Tools

health_check

Returns server health, uptime, version, and call stats

store_secret

Store an encrypted secret with optional rotation policy. Value is encrypted at rest with AES-256-GCM.

get_agent_token

Issue a short-lived, scoped token for an agent to use a secret. The agent receives an opaque token ID — never the raw secret. Use inject_secret_to_req

rotate_secrets

Rotate all secrets for a given service. Old values are overwritten, and all outstanding tokens for those secrets are invalidated.

audit_secret_access

View an audit trail of who accessed which secrets over a time range.

scan_config_for_leaks

Scan a config text for exposed secrets — API keys, tokens, passwords, private keys. Uses 12 regex patterns covering AWS, GitHub, OpenAI, Anthropic, Sl

inject_secret_to_request

Return a request object with the secret injected. Pass a token_id obtained from get_agent_token and a request template with a {{SECRET}} placeholder.

INFO Static analysis of npm package secure-vault-mcp@0.1.1 (stdio server — no remote endpoint). Reliability/behavioral signals require running it; not measured.

Agents: check this before connecting

Add the wmcp.sh trust oracle as an MCP server and call grade_mcp_server / check_mcp_drift in your agent's pre-connection gate:

How this grade is computed. An open, independent rubric — Spec conformance (20%), Security mapped to the OWASP MCP Top 10 (30%), Reliability (20%), Tool hygiene (15%), Transparency (15%) — run by connecting to the server and inspecting its real MCP surface. The grade is free and identical whether or not the operator pays. v1 uses static + spec signals from a single connection; continuous uptime, real latency, and annotation-truthing (declared readOnly vs observed behavior) layer on via the wmcp.sh proxy.
