description: >
  Creates and launches PostHog surveys through MCP, including NPS/CSAT popovers,
  hosted feedback forms, and headless surveys. Guides survey type selection,
  audience targeting, draft review, and launch readiness. Use when asked to
  create a survey or form, or before calling survey-create. For investigating
  an existing survey's delivery or responses, use debugging-surveys instead.

Creating surveys

Create a useful draft from the user's goal, then verify its audience and delivery before launch. The workflow can run through MCP without opening the survey editor.

Choose the delivery and questions

Infer the name, purpose, and questions from the request. Ask only for missing information that changes who receives the survey or how it is delivered.

| User's goal | Survey type | Delivery requirement | | --------------------------------------- | ----------------- | ---------------------------------------------------- | | Feedback inside an app | `popover` | A supported PostHog SDK with surveys enabled | | Always-available feedback button | `widget` | SDK support and a widget configuration | | A shareable hosted form | `external_survey` | A hosted survey link; no in-app targeting | | A custom form built in application code | `api` | The app renders questions and captures survey events |

Prefer one to three questions unless the user requests more. Use a rating plus an optional open question for NPS/CSAT, or choice questions with at least two choices. Inspect the current tool schema for question types, scales, branching, and translations instead of guessing their JSON shapes. Minimal starting points are in [examples](references/examples.md).

Survey names, questions, and appearance text are public content. Do not copy private customer details into them without making that visibility clear first.

Verify the audience and appearance

• Use `conditions` for URL, event, device, and linked-flag-variant conditions.

Resolve existing event and flag identifiers before using them. A URL condition does not define a person or cohort audience.

• Use `targeting_flag_filters.groups[].properties[]` for person, group, or cohort

targeting. Groups are alternative rules; properties within a group must all match. Preserve the intended audience when translating the request.

• Cohorts containing behavioral filters cannot be used directly for survey

targeting. Explain the restriction and offer a supported static snapshot or another equivalent audience definition. A snapshot does not update with the original cohort. Get agreement before making that tradeoff; never drop a rule or broaden the audience to make a failed request pass.

• Hosted forms (`external_survey`) do not use in-app display conditions or

targeting flags. Do not attach those fields to a hosted form.

• Omit `appearance` unless customization is needed. `whiteLabel: true` requires

the organization's white-labelling entitlement (Enterprise). Do not infer it from a request for custom colors. Verify entitlement before setting it. `surveyPopupDelaySeconds` must be non-negative.

• Leave optional fields unset when unused. Do not fill them with `null` as a

substitute for omission; question fields and nested objects have different nullability rules.

Create and review the draft

Call `posthog:survey-create` with the resolved configuration. Omit `start_date` for a draft. If the user already asked for immediate launch, continue through the readiness check and launch without asking for the same approval again.

Keep the returned survey `id`. Subsequent survey tools use `id`, not a question ID, feature flag ID, or survey name.

Read the saved survey with `posthog:survey-get`. Review the questions, type, audience, schedule, response limit, and branding with the user. Show the MCP survey app when the client supports it; otherwise give a concise text review. Always include the returned `_posthogUrl`. A saved configuration is not evidence that an in-app popup has rendered successfully.

For changes, call `posthog:survey-update` after fetching the saved survey. Questions, conditions, appearance, targeting, and translations may replace nested values. Preserve unchanged fields and existing question IDs, which link questions to collected responses. Omit IDs only for new questions.

Launch and verify delivery

Before `posthog:survey-launch`, confirm:

• The user authorized launch for the reviewed audience and configuration.
• The survey is not archived and has no `end_date` in the past. If reopening an

existing survey, unarchive it or clear/extend its end date only as authorized.

• For in-app delivery, surveys are enabled in the project and the app's SDK

supports the requested features. Event-triggered surveys need the actual triggering event in the app. Creating an event name in configuration does not instrument that event.

• For `api` surveys, the application implementation handles display and event

capture. Creating and launching the definition does not implement that code.

Use `posthog:survey-launch` with `id`, then verify the returned state. Report whether the survey is a draft, launched, or awaiting an SDK/setup step. For hosted forms, return a verified public form URL when available; `_posthogUrl` is the management page and is not a respondent link.

Use `posthog:survey-stats` or `posthog:surveys-responses-list` to check subsequent activity. Zero responses immediately after launch do not prove delivery failed. For a survey that should have been shown, follow `debugging-surveys`.

Recover from errors

Read the validation field and reason before retrying. For appearance failures, check branding entitlement and the supplied appearance fields. For targeting failures, verify cohort support and rule structu
