Growthbook MCP Tools (4)

growthbook_api_read

Make an authenticated GET request to the GrowthBook REST API. Use path (+ optional query string) exactly as shown in skill workflows that mention gb-call GET. Paths typically start with /api/v1/ or /api/v2/. Returns the raw response body on success. Queries the GrowthBook REST API — see https://docs.growthbook.io/api (OpenAPI: https://api.growthbook.io/api/v1/openapi.yaml).

growthbook_api_write

Make an authenticated mutating request (POST, PUT, PATCH, or DELETE) to the GrowthBook REST API. Use method + path (+ optional JSON body) exactly as shown in skill workflows that mention gb-call with those methods. Paths typically start with /api/v1/ or /api/v2/. Returns the raw response body on success. Mutates the GrowthBook REST API — see https://docs.growthbook.io/api (OpenAPI: https://api.growthbook.io/api/v1/openapi.yaml).

growthbook_list_skills

List available GrowthBook agent skills (name + description). Use growthbook_read_skill to load the full workflow for a skill before acting. Skills encode how to accomplish GrowthBook tasks well; use growthbook_api_read / growthbook_api_write to execute the REST calls they describe.
