Inspect rank movement

Read how source ranks move between a reference and checkpoint run. MCP tool: get_rank_displacement. Operation: read. Uses the authorized connection; no project or content changes are made by this tool.

Parameters

Name	Type	Required	Default	Meaning and accepted values
`project_id`	string	Yes	`Required`	Project ID from list_projects. Select the project in the intended workspace and environment.
`run_id`	string	Yes	`Required`	Run ID from list_runs for this project. Use the exact returned value and check readiness before reading measurements.
`reference`	string or object or null	No	`null`	Choose the comparison run: previous_run, first_run, or specific_run. For specific_run, include run_id. The request’s run_id is the checkpoint.
`aggregation_level`	string	No	`'domain'`	domain requests source-domain results; url requests individual-page results. Keep the same reporting unit when comparing measurements.
`n_boot`	integer	No	`Omit for standard use`	Optional advanced analysis control. Omit for standard reporting; use the advertised runtime schema if an integration requires it.
`group_by`	string[] or null	No	`null`	Split results into rows by the requested dimensions. Check both filters_applied.group_by and each row’s group_by_values before labeling the groups.
`filters`	object[] or null	No	`null`	Select measured answers with objects containing dimension and values. Use labels from list_dimension_options; inspect returned warnings for filters that were not applied.
`subject`	string or object or null	No	`null`	Choose sources with kind: leaderboard, all, owned, or specified. For specified, provide domains containing exact source keys for the requested reporting unit.

Example call

Replace ID placeholders and example selections with values from your account. This is the params object for MCP tools/call.

    "project_id": "PROJECT_ID",

Read the response

Read data.domain_details for rank movement, data.tier_events for entries and exits across the reported evidence boundary, and data.n_changed_domains for the combined changed-domain count. Retain available intervals and correction metadata.

Fields to use

These selected fields explain the example and the result to preserve. Field presence depends on the response; this is not a complete response schema.

Field	Meaning and use
`data.domain_details[].domain_or_url`	Source whose rank movement is reported.
`data.domain_details[].rank_baseline`	Rank in the reference measurement.
`data.domain_details[].rank_checkpoint`	Rank in the checkpoint measurement.
`data.domain_details[].rank_displacement`	Rank comparison with difference, uncertainty, and comparability. A positive rank-number change means a lower position.
`data.domain_details[].entered`	Whether the source entered the comparison’s reported evidence boundary.
`data.domain_details[].exited`	Whether the source exited that boundary; this does not mean it vanished from the internet.

Response example

Selected fields from an observed IQRush Dev response. Lists are shortened and project/run IDs are placeholders. Omitted fields remain available in the actual response.

Important behavior

Rank displacement and citation-share change are not interchangeable. A selected subject can return only part of the landscape. Check tool and payload errors before using the result. Response handling explains estimates and empty results; errors and recovery covers invalid requests and temporary failures. HTTP equivalent: Inspect rank movement. HTTP parameters and defaults can differ.
