Bump.sh

Bump.sh is a hosted platform that turns an API description into public or private documentation and, optionally, an MCP server for AI agents. It is built to update both whenever the API changes.

You connect an OpenAPI or AsyncAPI description, and the platform builds a documentation site from it. Each change to the spec is compared with the previous version, so breaking changes are flagged before they reach developers. Changes can come through a Git workflow, so docs go through the same pull request review as code. The platform can also host an MCP server built from workflow definitions, which lets an AI agent call your API through a governed interface rather than through hand-written glue code.

• Build API docs from an OpenAPI or AsyncAPI spec
• Preview and diff API changes on every pull request
• Flag breaking changes before they go live
• Host an MCP server built from workflow definitions
• Use a custom domain and single sign-on for docs

API product teams and platform teams that publish APIs to outside developers will find it useful. Companies that also want their APIs to be callable by AI agents can use the MCP part of the platform.

Plans and pricing are set by the vendor, so check the current options directly before choosing a tier. The service is hosted, and an on-premise option is also mentioned. Access controls, usage analytics and logs are part of the platform, which can help a team see how developers and agents use the API.
