create_secret_reference

Create a Portkey reference to a secret stored in AWS Secrets Manager, Azure Key Vault, or HashiCorp Vault. Returns a UUID and slug without exposing the resolved external secret.

Instructions

Create a reference to a secret stored in AWS Secrets Manager, Azure Key Vault, or HashiCorp Vault. Authentication credentials are sent to Portkey and exposed to this MCP transcript; use short-lived or workload identity modes when possible. Returns the new UUID and slug, never the resolved external secret.

Input Schema

TableJSON Schema

Name	Required	Description
`name`	Yes	Human-readable name
`slug`	No	Optional stable slug containing only letters, numbers, underscores, or hyphens; Portkey generates one when omitted
`tags`	No	Optional string key-value tags for filtering and organization
`secret_key`	No	Optional key within a structured external secret; null uses the whole secret value
`auth_config`	Yes	Choose exactly one documented authentication shape matching manager_type. Credentials are sent to Portkey and visible in the MCP transcript; prefer workload identity or short-lived credentials when available.
`description`	No	Optional description; use null to leave it empty
`secret_path`	Yes	Path of the secret in the external secret manager
`manager_type`	Yes	External secret manager: aws_sm for AWS Secrets Manager, azure_kv for Azure Key Vault, or hashicorp_vault for HashiCorp Vault; must match the auth_config field family
`organisation_id`	No	Organisation UUID; required when the MCP server is not authenticated with a Portkey API key
`allowed_workspaces`	No	Workspace UUIDs or slugs allowed to use this reference; omit when allow_all_workspaces is true
`allow_all_workspaces`	No	Whether every workspace may use this reference; defaults to true and cannot be true with allowed_workspaces

Output Schema

TableJSON Schema

Name	Required	Description
`ok`	Yes	Whether the tool call succeeded and returned structured data
`data`	No	Structured success payload when ok is true
`error`	No	Structured error payload when ok is false

A4.2/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Goes beyond the annotations by disclosing a real behavioral trait: authentication credentials are transmitted to Portkey and exposed in the MCP transcript, and the response returns only the UUID and slug, never the resolved secret value. This credential-exposure warning is exactly the kind of context annotations (readOnlyHint=false, destructiveHint=false) cannot convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, tightly front-loaded with the action, then the security caveat, then the return contract. No filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists and annotations cover the mutation profile, so the description's job is to add what those miss — it does so with the credential-transcript warning and the 'never returns the resolved secret' guarantee. Minor gap: no idempotency/duplicate-slug behavior for a create operation the annotations mark non-idempotent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and the auth_config union is thoroughly documented in-schema, so the baseline is 3. The description adds only the high-level manager list, not syntax or format detail beyond what the schema already provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Create a reference to a secret') and enumerates the supported external managers, which cleanly separates it from get_secret_reference, update_secret_reference and delete_secret_reference in the sibling list.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives an actionable usage preference ('use short-lived or workload identity modes when possible'), which steers the agent toward the safer auth shapes. It does not, however, name the sibling alternatives (update/delete/get_secret_reference) or state when not to use this tool.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
