Official

create_user_request

Creates a verification request that asks another user to share verified assets like email, phone, or domain, with optional channels, expiry, and callback updates.

Instructions

Create a new verification request to ask another user to share verified assets. Each asset is an object naming its type, e.g. { "type": "email" }.

ACCESS: needs a Proof account. Set PROOF_API_KEY and restart this server, or sign in with start_login — a session opens this tool — then call this tool again.

Input Schema

NameRequiredDescriptionDefault
assetsYesAssets to request, e.g. [{ "type": "email" }, { "type": "phone", "required": false }]
partial_okNoWhether partial asset sharing is acceptable (default: false)
action_typeNoPurpose of the request (default: verification); custom and confirmation also need an action_context title
callback_urlNoHTTPS webhook URL for request status updates
redirect_urlNoHTTPS URL to redirect the subject after completing the request
reference_idNoExternal reference ID for tracking
action_contextNoWhat the recipient is shown about why the assets are needed, e.g. { "title": "Confirm your contact details" }
expires_in_hoursNoHours until request expires (default: 168, i.e. 7 days)
public_profile_idNoPublic profile ID for branding
validity_requirementNoHow recently an existing proof must have been verified for the recipient to reuse it: a number and a unit, h hours, d days, w weeks or m months (30 days), e.g. "24h", "7d", "1m"

Output Schema

NameRequiredDescriptionDefault
idNoMongoDB ObjectId
assetsNo
statusNoStatus of a verification request
progressNo
created_atNo
expires_atNo
partial_okNo
updated_atNo
action_typeNoType of action for verification request or authorization
callback_urlNoThe webhook URL set on the request, if any
completed_atNo
redirect_urlNo
reference_idNo
action_contextNoThe action the person is asked to authorize; null when the request carries none
computed_stateNoAdditive machine-readable effective state: re-derives expiry from expires_at (never trusts the stored status). BOTH `is_expiring_soon` and `next_action` are role-aware — `next_action.role` says which side this envelope was computed for, and the two fields are consistent within it. Present only on authenticated owner/requester and recipient responses; absent on public/third-party surfaces.
verification_urlNoURL for the verification flow
validity_requirementNoRequired proof freshness as set on the request (e.g. "7d"); null when none was set

  3. First observedv1.1.0

TDQS

A3.9/5.0
Behavior4/5

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

Beyond readOnlyHint=false and destructiveHint=false, it discloses account and authentication requirements, the server-restart requirement, session-based access, and the need to call the tool again after signing in. It adds less about the resulting request's lifecycle or what happens after creation.

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 purpose is front-loaded, and the separate ACCESS paragraph makes setup and recovery steps easy to scan. The asset sentence is somewhat redundant with the richly documented schema, but the description remains compact and focused.

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?

Together with the complete input schema, output schema, and safety annotations, the description provides enough purpose and access context for successful invocation. Its main remaining gap is selection context among near-duplicate creation siblings, particularly create_verification_request.

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%, so the schema already documents the assets structure, allowed types, defaults, and constraints in detail. The minimal email-asset example is helpful but substantially repeats the schema's own description and example rather than adding new semantics.

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

Purpose4/5

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

The opening sentence gives a specific verb, resource, and audience: creating a verification request that asks another user to share verified assets. It does not distinguish this tool from the especially close sibling create_verification_request or other creation tools.

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?

The description supplies concrete prerequisites and two actionable authentication paths: configure PROOF_API_KEY and restart, or use start_login and retry. It clearly establishes the sharing-request use case, but gives no guidance on when to prefer this tool over create_verification_request or related alternatives.

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