MCP tool
approve_plan
Approve a draft media plan. This locks the plan and creates a campaign with one channel-campaign per plan line, all in status "pending". Returns the new campaign including its id — use launch_campaign to activate it. Fails with 409 if the plan is already approved.
Input
Pass fields from this schema as the tool arguments. Runtime ownership, product scope and readiness checks still apply.

}REST mapping and authority
The tool wraps this REST endpoint. The mapping identifies path/query/body transformations and approval or idempotency headers.
{
"method": "POST",
"path": "/api/v1/plans/{planId}/approve",
"pathFields": [
"planId"
],
"pathSchema": {
"type": "object",
"properties": {
"planId": {
"type": "string",
"description": "draft plan id to approve"
}
},
"additionalProperties": false,
"required": [
"planId"
]
},
"pathEncoding": "encodeURIComponent for each path field",
"governedAction": "plan.approve",
"headers": {
"x-chorus-agent-step-id": "agentStepId",
"x-chorus-agent-action-digest": "expectedActionDigest"
},
"body": null,
"responseMapping": "REST JSON is returned as MCP structuredContent and a compatibility text block; privacy-sensitive tools validate their output schema."
}Output
This is the registered MCP output envelope. Nested fields are only modeled where the schema explicitly defines them.

"type": "object",
"properties": {
"campaign": {
"type": "object",
"propertyNames": {
"type": "string"
},
"additionalProperties": {}

},

"campaign"
],
"additionalProperties": {}
}Safety annotations
{
"readOnlyHint": false,
"destructiveHint": true,
"idempotentHint": true,
"openWorldHint": false
}Annotations help a client present the tool. The API independently enforces authorization and exact action approvals. Error and retry guidance →
