generate_secret

[secrets] Generate a cryptographically random secret using Node's CSPRNG and optionally store it in the keyring in one step.

Instructions

[secrets] Generate a cryptographically random secret using Node's CSPRNG and optionally store it in the keyring in one step. Use to create new credentials that you control (signing keys, internal tokens, passwords); for issuer-issued credentials (Stripe/OpenAI etc.) use rotate_secret to ask the upstream provider for a fresh key, and use set_secret for values you already have in hand. If saveAs is provided this mutates the keyring (one 'write' event) and returns a summary like 'Generated and saved as "KEY" (FORMAT, ~N bits entropy)'. Without saveAs the call is read-only and returns JSON { ok, data: { value } } containing the freshly generated string.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
orgIdNoOrganization identifier for org-scoped secrets. Required only when scope='org'. Example: 'acme-corp'.
scopeNoWhere the secret lives. 'global' = user keyring (default if omitted on reads), 'project' = scoped to projectPath, 'team' = team-shared (needs teamId), 'org' = org-shared (needs orgId).global
formatNoOutput shape. 'hex' / 'base64' / 'alphanumeric' = raw random string of `length` characters; 'uuid' = RFC4122 v4; 'api-key' / 'token' = random alphanumeric with optional `prefix`; 'password' = mixed-case alphanumeric with symbols. Defaults to 'api-key'.api-key
lengthNoNumber of characters (or bytes for hex/base64) to generate. Ignored for 'uuid'. Defaults to a sensible per-format value (e.g. 32 for api-key).
prefixNoLiteral prefix prepended to the random portion. Only meaningful for 'api-key' and 'token'. Example: 'sk-' or 'svc_'.
saveAsNoIf provided, store the generated value at this key name in the keyring (one mutation). Omit to just return the value without persisting.
teamIdNoTeam identifier for team-scoped secrets. Required only when scope='team'. Example: 'acme-platform'.
projectPathNoAbsolute path to the project root for project-scoped secrets and policy resolution. Defaults to the MCP server's current working directory when omitted.

TDQS

A4.5/5.0
Behavior4/5

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

Despite no annotations, the description elaborates on cryptographic randomness, side effects (one write event when saveAs is provided), and return formats. However, it lacks details on error handling or security permissions needed.

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

Conciseness4/5

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

The description is a single dense paragraph that efficiently conveys purpose, usage, and behavioral details without waste. It could be slightly more structured but remains clear and compact.

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?

With 8 parameters, no output schema, and no annotations, the description covers generation, storage, format variations, and return values. It lacks error scenarios and rate limits but is otherwise thorough for agent decision-making.

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

Parameters4/5

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

Schema description coverage is 100%, so the baseline is 3. The description adds value by grouping parameters and explaining conditional behavior (e.g., scope requirements, saveAs effect), but does not introduce new parameter details beyond the schema.

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?

The description clearly states that the tool generates a cryptographically random secret using Node's CSPRNG and optionally stores it. It explicitly distinguishes from sibling tools rotate_secret and set_secret by specifying use cases.

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

Usage Guidelines5/5

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

The description provides explicit guidance on when to use this tool: 'Use to create new credentials that you control' versus 'rotate_secret' for issuer-issued credentials and 'set_secret' for existing values. It also clarifies the read-only vs mutating behavior based on whether saveAs is provided.

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