Akeyless (SecretlessAI and MCP server) vs Infisical

Akeyless (SecretlessAI and MCP server)

Gateway-brokered SecretlessAI and a runtime-authority MCP server with 4 tools that return results, not credentials. No published prices above the free plan; clients and transactions are metered with overage billed at the end of a 12-month contract.

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.

Akeyless (SecretlessAI and MCP server)

1. Run akeyless mcp-runtime-authority, not akeyless mcp, for an agent that acts on systems; the first returns results, the second has get_secret and get_password
2. Authenticate with a cloud identity, Kubernetes or Universal Identity rather than an access key, which the docs reserve for proofs of concept
3. Use CLI 1.130.0 or later for either MCP server, and point the client at your Gateway URL
4. Count identities and calls before scaling. The free plan allows 5 clients, and calls over a tier's cap (200 a minute on Silver) are billed as extra clients, not refused
5. Pass the token in the JSON body of each POST, and page /list-items with pagination-token

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
