campaign_plan_update

Edit a Campaign Plan. A real change returns an approved Campaign Plan to draft.

Ask the agent to change the fields of a Campaign Plan: its name, its brand, its envelope, its dates or its body. The body is one markdown document: why this split, and how the result will be judged. The agent sends only what changes.

“Move the end of the spring sale Campaign Plan to 30 June, and raise the envelope to €7,500.”

The agent reads the Campaign Plan, then calls campaign_plan_update with the revision of the Campaign Plan that it read. You see the Campaign Plan as it is now. When the Campaign Plan was approved, a real change returns it to draft. When another change came first, AdCrunch refuses the write, and the agent reads the Campaign Plan again. The currency cannot change after a Line Item has a budget. To change a Line Item, the agent calls line_item_update.

Plan a campaign walks the whole job.

Reference

Update a Campaign Plan. Omit a field to leave it alone; send null to clear it. Pass base_revision from campaign_plan_get. Any real change returns an approved plan to draft — an approval refers to particular content and cannot outlive it; a write that changes nothing leaves the approval standing. The currency is refused once any Line Item carries a budget or a cost target (cpa, cpc or cpm), because re-denominating a costed plan would silently reinterpret every number in it. A Campaign Plan is AdCrunch’s own planning document — it is not a campaign on Meta or Google. For those, use list_campaigns and get_campaign.

Input

Argument	Type	Required	Description
`base_revision`	integer	yes	The revision of the Campaign Plan, as you last read it via campaign_plan_get. Guards against writing over a change somebody else made since.
`body`	string, 1 to 50000 characters or null	no	The whole new body, in markdown: it replaces the old one. Pass null to clear it. A change reverts an approved plan to draft.
`brand_name`	string or null	no	Re-point the plan at another brand by slug; null unlinks it. Refused while a Line Item still names a persona of the current brand.
`campaign_plan_name`	string	yes	The Campaign Plan slug — its stable per-organization handle.
`currency`	string, 3 characters	no	ISO 4217. Refused once any Line Item carries a budget — nothing is ever converted.
`description`	string	no
`end_date`	string or null	no	null makes the plan always-on, which also flips every inheriting line from a total to a daily rate.
`name`	string	no
`slug`	string	no	A new slug handle — a deliberate rename.
`start_date`	string or null	no
`total_budget`	number, at least 0 or null	no	null means “no declared constraint”, not zero.

Output

A successful call returns this object in structuredContent.

Field	Type	Always present	Description
`campaignPlan`	object	yes	The Campaign Plan as it is now, with the number of its Line Items. `line_item_list` gives the Line Items.
`campaignPlan.allocation`	object	yes	The money of the Campaign Plan. AdCrunch calculates it on each read and does not store it.
`campaignPlan.allocation.allocated`	number or null	yes	The sum of the Line Item budgets, in whole units of the currency. `null` when the Line Items with a budget do not share a unit.
`campaignPlan.allocation.comparable`	boolean	yes	`false` when the Line Items with a budget mix totals and daily rates. Then no sum exists: say “not comparable”, and do not add the budgets.
`campaignPlan.allocation.unallocated`	number or null	yes	The envelope less the allocated sum. It can be negative. `null` when the envelope is not set, when the Line Items do not share a unit, or when the unit is `daily`.
`campaignPlan.allocation.unit`	one of `total`, `daily` or null	yes	The unit that the Line Items with a budget share. `null` when no Line Item has a budget, or when the Line Items do not share a unit.
`campaignPlan.assignees`	array of object	yes	The current members who are accountable for the record, oldest first, at most 10. An Assignee grants no access.
`campaignPlan.assignees[].id`	string	yes	The `usr_…` id of the member.
`campaignPlan.assignees[].name`	string	yes	The name of the member.
`campaignPlan.body`	string or null	yes	The long markdown document of the Campaign Plan: the argument for the split, how the result is judged, and anything else a reviewer reads. `null` when nobody wrote it.
`campaignPlan.brand`	object or null	yes	The Brand that the Campaign Plan is for, or `null` when it has no Brand or its Brand was deleted.
`campaignPlan.brand.name`	string	yes	The display name of the Brand.
`campaignPlan.brand.slug`	string	yes	The slug of the Brand. Each tool takes it as `brand_name`.
`campaignPlan.brandId`	string or null	yes	The Brand that the Campaign Plan is for, `brd_…`, or `null`.
`campaignPlan.commentCount`	number	yes	The number of live Comments on the Campaign Plan, replies included. List them with `campaign_plan_comment_list`.
`campaignPlan.createdAt`	number	yes	Milliseconds since the Unix epoch, UTC.
`campaignPlan.createdBy`	string	yes	The user who created the Campaign Plan, `usr_…`.
`campaignPlan.currency`	string	yes	ISO 4217. Each amount of the Campaign Plan and of its Line Items is in whole units of this currency. It cannot change after a Line Item has a budget.
`campaignPlan.description`	string	yes	One sentence that tells the Campaign Plan apart in a list.
`campaignPlan.endDate`	string or null	yes	The last day of the Campaign Plan, or `null`. With no end date, the Campaign Plan is always on, and the budget of a Line Item with no end date of its own is a daily rate.
`campaignPlan.id`	string	yes	The id of the Campaign Plan, `cpl_…`.
`campaignPlan.lineItemCount`	number	yes	The number of live Line Items of the Campaign Plan. List them with `line_item_list`.
`campaignPlan.name`	string	yes	The display name.
`campaignPlan.revision`	number	yes	The revision of the Campaign Plan. It increments when the Campaign Plan changes. Send it as `base_revision` to `campaign_plan_update` or `campaign_plan_delete`. A Line Item has a revision of its own.
`campaignPlan.slug`	string	yes	The slug of the Campaign Plan. Each tool takes it as `campaign_plan_name`.
`campaignPlan.startDate`	string or null	yes	The first day of the Campaign Plan, or `null`.
`campaignPlan.status`	one of `draft`, `approved`	yes	`approved` when a person approved the content at this revision in the AdCrunch console. It is a record, not a gate: the provider write tools do not check it. A real change to the Campaign Plan, or a Line Item that is added or deleted, returns it to `draft`.
`campaignPlan.totalBudget`	number or null	yes	The envelope: the money that you have, in whole units of `currency`. `null` means no declared limit, not zero.
`campaignPlan.updatedAt`	number or null	yes	When the Campaign Plan last changed, or `null` when it never changed.

Failure codes

A failed call has isError set, and structuredContent.error holds one of these codes. Errors describes the shape of a failed call.

invalid_currency
invalid_amount
invalid_window
persona_not_in_brand

Scope

The token must hold campaign_plan:write. Auth & scopes lists each scope.

Annotations

A client reads these hints. A hint that the tool does not declare has the default value of the MCP specification.

Writes. The tool can change data.
Destructive. The tool can make a change that you cannot undo. A client can ask you to confirm before it calls the tool.
Not idempotent. A second call with the same arguments can change more.
Closed world. The tool reads and writes the data of AdCrunch only.
