List targets

list_targets List explicitly monitored destination URLs. Checks are independent of source-link presence.

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
`watches:read`	Reads saved data

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": "list_targets",
    "arguments": {}
  }
}

linktrail call list_targets --args '{}'

curl "$LINKTRAIL_API_URL/v1/commands/list_targets" \
  -H "Authorization: Bearer $LINKTRAIL_API_KEY" \
  -H 'Content-Type: application/json' \
  --data '{}'

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.

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
`cursor`	string	Optional	Opaque continuation returned by this same listing; omit for the first page.
`limit`	integer	Optional	Maximum rows in this page or bounded report; subject to the schema maximum. minimum: 1; maximum: 100; default: 50
`projectId`	string	Optional	Identifier of the project returned by its create or list operation. minLength: 1; maxLength: 200
`q`	string	Optional	Text filter applied to saved records; does not start discovery. maxLength: 500
`state`	string	Optional	Requested resource state or saved-observation filter, as enumerated here. maxLength: 40
`status`	string	Optional	Lifecycle status filter or requested status; this is separate from observation state. values: “active”, “paused”

Validation and omitted values

Omit cursor for the first page. Keep continuation cursors opaque and use them only with the same listing and filters. Omitting projectId reads the accessible workspace scope rather than selecting a different project. Pages are ordered by creation time, then identifier, ascending. Omitted q, state and status apply no corresponding filter. Search matches the saved destination URL case-insensitively.

Defaults when omitted

Field	Default
`limit`	`50`

Errors and retries

The command is annotated idempotent. Reuse an accepted idempotency key when the input provides one; changing the payload under a reused key can conflict. 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.
