Get a secret
One secret’s metadata: delivery mode, host binding, sharing, and when it was last handed to a run. Never its value. A secret from another project — and another member’s personal secret — both read as 404.
Authorizations
MCPJam API key (sk_…). Create one at Settings → API keys. Guest sessions cannot use the API, and API keys cannot manage other API keys.
Path Parameters
ID of the hosted project that contains the server.
Secret ID, as returned by the project's secret list.
Response
The secret, as metadata.
A project credential — METADATA ONLY, always. There is no value field on this schema and no route that returns one: a secret is written and delivered into a run, never read back.
The environment-variable name (^[A-Z_][A-Z0-9_]*$). This IS the secret's identity: what a materialized delivery exports, what a workflow references, and what stays stable across a rotation. Immutable.
brokered — the sandbox's egress proxy injects the value as a request header OUTSIDE the VM, so the box never holds it. Prevents EXTRACTION, not USE: any process in the box can call the bound host while the policy is live, and it works for HTTPS APIs only (domain rules bind on ports 80/443). materialized — a real environment variable inside the box, which is the only thing a CLI can read; EXTRACTABLE BY DESIGN.
brokered, materialized project — admin-managed, delivered to every member's sessions. user — personal, delivered ONLY in sessions its owner starts and silently absent from anyone else's run of the same environment. Immutable.
user, project When this secret was last HANDED TO a run — not when it was last used. Brokered use is unobservable by construction (the proxy injects the header; the request is never seen here), so used would be a number nobody can honestly produce. null means nothing has been recorded, which is not the same as never delivered.
Brokered only: the exact hostnames the header is injected on.
Brokered only: the header name.
Brokered only: the header value, with {} where the secret goes.
Personal secrets only. Project-shared rows have no owner.
