## Which one, for what

### Infisical (A)

Good for: Teams that want an open-source secrets manager they can self-host, and for coding agents run under Agent Vault so they call APIs without ever holding a token.

Ahead on:
- Reliability, 100 against 76
- Schema & documentation, 87 against 71
- Agent ergonomics, 91 against 63
- Security & auth, 91 against 86
- Payments & pricing, 30 against 20
- Transparency & trust, 83 against 78

Also in its favour:
- Agent-ready, a grade of BB or better
- A hosted endpoint, with nothing to install
- Open source

Watch for: Free has no audit logs, Pro keeps them 30 days, and dynamic secrets need Advanced at $40 an identity a month

### 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.

## Verdicts

**Infisical.** Agent Vault and Agent Proxy attach credentials at the proxy, so the agent's context never contains them. Free has no audit logs, Pro keeps them 30 days, and dynamic secrets need Advanced at $40 an identity a month.

**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

### Infisical

1. Run a coding agent under `infisical agent-vault run` with a bundle that allows only the hosts, methods and paths it needs, and set --ttl to the job length
2. Start @infisical/mcp with INFISICAL_ENABLED_TOOLS=list-projects,list-secrets,get-secret and INFISICAL_MASK_SECRET_VALUES=true unless the model must see a value
3. Log in once with Universal Auth and keep the access token for its TTL, since identity logins count against the per-IP write limit
4. Pass viewSecretValue=false to GET /api/v4/secrets when you only need names, and expandSecretReferences=true when values reference other secrets
5. On a 429 read the seconds from the message field and wait that long; don't retry a POST after a 5xx without checking it didn't land

### 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
