Invite member

invite_member Invite one email address as admin, member or viewer, optionally scoped to specific projects. Returns a join token ONCE; only its hash is stored. The token alone is NOT enough to join , the accepting user’s VERIFIED email must match the invitation, so a forwarded link cannot admit a stranger. An invitation can never grant a role or a project the inviter does not hold, and owner is not invitable: transferring ownership is its own act. Linktrail does not send the email; hand the token to the person yourself.

Hosted MCP registration verified. These schemas describe the development contract; confirm supported inputs with tools/list. Generic CLI/HTTP calls require a matching development server. Configure LINKTRAIL_API_URL; production does not expose these command routes.

Access	Behavior
`projects:write`	Writes or admits work

Reading saved data does not start a verification job. Mutations can change saved records or access; the effects below apply.

Example request

Connect through MCP, CLI, or HTTP. Replace example identifiers with records from your workspace.

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "invite_member",
    "arguments": {
      "email": "reader@example.com"
    }
  }
}

linktrail call invite_member --args '{"email":"reader@example.com"}'

curl "$LINKTRAIL_API_URL/v1/commands/invite_member" \
  -H "Authorization: Bearer $LINKTRAIL_API_KEY" \
  -H 'Content-Type: application/json' \
  --data '{"email":"reader@example.com"}'

Returned result

Illustrative data validated against the documented response schema. IDs and dates are examples, not a live account capture. MCP returns this data in structuredContent and in a text content block; generic HTTP and CLI return the JSON result directly.

{
  "id": "invite_example",
  "workspace_id": "ws_example",
  "email": "reader@example.com",
  "role": "member",
  "project_ids": null,
  "invited_by": "user_example",
  "created_at": "2026-09-13T12:00:00.000Z",
  "expires_at": "2026-09-20T12:00:00.000Z",
  "accepted_at": null,
  "revoked_at": null,
  "state": "open",
  "token": "example_invitation_token_not_a_credential"
}

Input fields

Omit optional fields when you do not want to supply them. Null is accepted only where listed. Unknown input properties are rejected.

Field	Type	Presence	Meaning and constraints
`email`	string	Required	Email address to bind an invitation to; Linktrail does not send the invitation. minLength: 3; maxLength: 254
`role`	string	Optional	Workspace access role; cannot exceed the acting member’s authority. default: “member”; values: “admin”, “member”, “viewer”
`projectIds`	array	Optional	Accessible project IDs. Where nullable, null grants all projects. minItems: 1; maxItems: 100

Validation and omitted values

Omitting projectIds requests workspace-wide access; it cannot exceed the inviter grant. The accepting user must have the matching verified email. The returned token is shown once; this operation does not send email.

Defaults when omitted

Field	Default
`role`	`"member"`

Output fields

Errors and retries

This command is not annotated idempotent. After a timeout, inspect existing state before repeating a write. See error recovery for status, scope, cooldown, cursor and retry handling. Unknown observations are result data and do not establish loss.

HTTP resource routes

These existing resource routes share the operation’s domain behavior. Their parameter placement, status and response envelope can differ from generic invocation. See HTTP route details.
