Bump.sh
What Bump.sh is
Bump.sh is a paid platform for publishing API documentation and providing MCP servers that update with API releases. It supports OpenAPI, AsyncAPI, and Arazzo, with interactive references, code samples, API versioning, and custom domains. Pull-request previews show documentation changes and detect breaking API changes before publication. Bump.sh generates managed MCP servers from workflow definitions, which can run hosted or on-premise. Integrations include its CLI and API, GitHub Actions, Slack notifications, and custom webhooks. The GitHub Action runs in the customer’s environment and has read-only access to explicitly selected repositories and files. The cloud-only service hosts customer data in Europe, and every plan includes human support. Basic costs $50/month with 10 API docs, 5 MCP tools, 3 internal users, and 20 external users. Pro costs $120/month with 30 API docs, 50 MCP tools, 5 internal users, and 40 external users. Custom pricing includes custom API docs and MCP tools and unlimited users. Bump.sh states it lacks SOC 2, ISO 27001, and similar certifications.
