## Which one, for what

### Bitwarden Secrets Manager (C)

Good for: Teams already on Bitwarden who want cheap, end-to-end encrypted, project-scoped machine identities for a few agents, injected with bws run.

Ahead on:
- Payments & pricing, 25 against 20

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No release since 22 May 2026, and the npm SDK is still 1.0.0 from September 2024

### Keeper Secrets Manager (B)

Good for: Companies already on Keeper's business vault that want per-device machine identities with client-side decryption and an official MCP server.

Ahead on:
- Reliability, 76 against 71
- Schema & documentation, 71 against 53
- Agent ergonomics, 63 against 52
- Security & auth, 86 against 76
- Maintenance & community, 92 against 36

## Verdicts

**Bitwarden Secrets Manager.** End-to-end encrypted, decrypted only on the client that holds the token. No release since 22 May 2026, and the npm SDK is still 1.0.0 from September 2024.

**Keeper Secrets Manager.** Each client device signs requests with its own key, is locked to an IP address by default and can be revoked alone, and secrets decrypt only on the client. The add-on has no public price, no request limits were found in the reviewed documentation, and a person must create the application and device in the vault.

## Before you call either

### Bitwarden Secrets Manager

1. Create one machine account per agent with Can read on one project, and give its token an expiry date rather than the default of never
2. Run the agent under `bws run -- <cmd>` so secrets arrive as environment variables and aren't written to disk or into the context
3. Fetch with `bws secret list <project-id> --output json` once per run; `bws secret get` needs the secret's UUID, not its name
4. Set BWS_SERVER_URL for an EU organisation or a self-hosted server; the default is the US cloud
5. Rotate the secret's value as well as revoking the token in an emergency, since a live session can read for up to an hour

### Keeper Secrets Manager

1. Ask the vault owner for a new device on an application that holds only the folders the task needs. Use the Base64 configuration, not the first one-time token
2. Run commands under `ksm exec` so secrets arrive as environment variables and stay out of the model's context
3. Expect HTTP 403 with `{"error":"throttled"}` under load. The Python SDK retries five times from 11 seconds, so allow for long waits
4. A device is locked to the IP address it first connects from unless it was created with `--unlock-ip`. Check this before running from a dynamic address
5. Leave `--auto-approve` off on the MCP server. It removes confirmation for deletes and for unmasking values
