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, its rationale or its measurement. 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, 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_entities and get_entity.

Input

Argument	Type	Required	Description
`base_revision`	integer	yes	The revision you last read via campaign_plan_get. Guards against writing over a change somebody else made since.
`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.
`measurement`	string or null	no
`name`	string	no
`rationale`	string or null	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 its Line Items in full.
`campaignPlan.allocation`	object	yes	The money of the Campaign Plan. AdCrunch calculates it on each read and does not store it.

`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.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.lineItems`	array of object	yes	Each Line Item of the Campaign Plan, in full.

`campaignPlan.lineItems[].channel`	one of `meta`, `tiktok`, `snapchat`, `google_search`, `google_pmax`, `google_display`, `youtube`, `programmatic_display`, `linkedin`, `x`	yes	What the Line Item buys, in planning words. A channel is not a provider.

`campaignPlan.lineItems[].createdAt`	number	yes	Milliseconds since the Unix epoch, UTC.
`campaignPlan.lineItems[].createdBy`	string	yes	The user who added the Line Item, `usr_…`.
`campaignPlan.lineItems[].effectiveEndDate`	string or null	yes	The end that applies: the end date of the Line Item, else the end date of the Campaign Plan. `null` when neither has one.
`campaignPlan.lineItems[].effectiveStartDate`	string or null	yes	The start that applies: the start date of the Line Item, else the start date of the Campaign Plan. `null` when neither has one.
`campaignPlan.lineItems[].endDate`	string or null	yes	The end date of the Line Item itself, or `null` when the Line Item uses the end date of the Campaign Plan.
`campaignPlan.lineItems[].executable`	boolean	yes	`true` when AdCrunch can create objects for this channel today. It is not a promise that a create succeeds.
`campaignPlan.lineItems[].executions`	array of object	yes	The provider objects that the Line Item created, as `line_item_record_execution` recorded them. The list does not tell whether the Line Item is complete.

`campaignPlan.lineItems[].executions[].id`	string	yes	The id of the record, `exe_…`.
`campaignPlan.lineItems[].executions[].mutationWorkflowId`	string or null	yes	The `workflowId` of the change that created the object, or `null` when the record names none.
`campaignPlan.lineItems[].executions[].provider`	one of `meta`, `gads`, `tiktok`, `x`, `openai`, `snapchat`, `dv360`	yes	The provider of the object.
`campaignPlan.lineItems[].gender`	one of `all`, `men`, `women` or null	yes	The gender of the audience, or `null` when it is not decided. `null` executes as `all`.

`campaignPlan.lineItems[].personaId`	string or null	yes	The Persona that explains the audience, `psn_…`, or `null`. The countries, the ages and the gender are what execute.
`campaignPlan.lineItems[].provider`	one of `meta`, `gads`, `tiktok`, `x`, `openai`, `snapchat`, `dv360` or null	yes	The provider that sells the channel, or `null` when AdCrunch has no integration for it.
`campaignPlan.lineItems[].revision`	number	yes	The revision of the Line Item. It increments when the Line Item changes. Send it as `base_revision` to `line_item_update`, `line_item_delete` or `line_item_validate`.

`campaignPlan.lineItems[].status`	one of `draft`, `validated`	yes	`validated` when a person cleared the Line Item to run, by `line_item_validate` or by the approval of the Campaign Plan. A real change to the Line Item returns it to `draft`.
`campaignPlan.lineItems[].unit`	one of `total`, `daily`	yes	How to read `budget`. `total` when the Line Item has an effective end date: the budget is for the whole period. `daily` when it has none: the budget is for each day.

`campaignPlan.measurement`	string or null	yes	How the result is judged, or `null`.

`campaignPlan.rationale`	string or null	yes	The argument for the split of the money, or `null`. A reviewer approves it.

`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. 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.

Failure codes

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

not_found
invalid_slug
invalid_currency
invalid_amount
invalid_window
persona_not_in_brand
currency_frozen
revision_mismatch
slug_conflict
forbidden
invalid_request
internal_error

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.
