Bump.sh: cost, fit and limits
Bump.sh is an API documentation and MCP platform made by It Ducks, a French company, that publishes versioned docs from OpenAPI, AsyncAPI or Arazzo files and turns an API ecosystem into hosted MCP servers for AI agents.
What to know first
Bump.sh lists Basic at $50 a month, Pro at $120 a month and a custom-quoted tier. There is no free plan, but Pro has a 14 day trial and open source projects can get free Pro access. Basic caps the account at 10 API docs, 5 MCP tools and 3 internal users. The privacy policy names Heroku as a server provider without a region.

Who Bump.sh is best for
Teams with several API formats
OpenAPI, AsyncAPI and Arazzo are supported on Basic, so REST, event-driven and workflow descriptions can sit in one documentation hub.
Teams opening their API to agents
The platform hosts MCP servers with built-in authentication and observability, and shows an MCP preview on every pull request, so changes are seen before release.
Open source maintainers
The pricing page lists free Pro access for open source projects, which gives branch management and the API Explorer to a project that would not pay.

What Bump.sh does
- Managed MCP platform
- Turns an API ecosystem into hosted MCP servers with built-in authentication and observability, so agents call the API through a controlled endpoint. Pro raises the cap to 50 MCP tools and adds private MCP servers.
- MCP preview and live debug
- Shows an MCP preview on every pull request and an MCP live debug view, named on the product page, so reviewers can see how agents will use a change.
- Versioned docs and changelogs
- Publishes API docs from OpenAPI, AsyncAPI or Arazzo files with automated changelogs and versioning, and Pro adds release rollback. Basic already includes API docs and hubs, and a custom domain and logo are part of it.
- Git workflow
- Supports branches, pull requests and CI checks through a CLI and GitHub integration, and full CI integration is on Pro. The pages also list the GitHub integration on Basic, with full CI integration reserved for Pro.
- Deployment choice
- The MCP runtime can be hosted or on-premise, with private MCP servers and custom OAuth providers, and usage analytics and logs cover docs and MCP servers.
How Bump.sh handles your data
Bump.sh's privacy policy names It Ducks as the company and gives retention periods for contract data (the duration of the contract), contractual liability (five years after termination) and navigation data (no longer than six months). It does not give a period for customer API content. The policy says data may be transferred to servers outside France and names Heroku as a server provider without a region. It has no statement on AI training and names no certifications. The Security page was not opened.
Where Bump.sh falls short in practice
- Low caps on Basic. Basic allows 10 API docs, 5 MCP tools and 3 internal users, and Pro raises these to 30, 50 and 5, so a growing platform team meets the ceiling quickly.
- No free plan. Only a 14 day trial on Pro is listed, plus free Pro access for open source projects, so a private company has no free tier to keep after the trial.
- Enterprise features are quote only. SSO, reverse proxy and embed mode, and the on-premise MCP dataplane are listed under Custom only, so security teams must start a sales conversation. Pro lacks them as well.

Alternatives to Bump.sh
Bump.sh: common questions
Where is Bump.sh based?
The privacy policy names It Ducks as the company behind the Bump.sh brand and gives France as its country. The same policy says data may be transferred to servers outside France and names Heroku as a provider, without a region, so company address and hosting location differ.
Does Bump.sh have a free plan?
No free plan is listed. Pro has a 14 day free trial, and the pricing page offers free Pro access for open source projects. Paid access starts with Basic at $50 a month, billed monthly, with 10 API docs and 5 MCP tools.
What API formats does Bump.sh support?
Basic lists OpenAPI, AsyncAPI and Arazzo, with API docs and hubs, MCP servers, a CLI and a GitHub integration. Docs are published from those files with automated changelogs and versioning, so there is no separate editor for writing API descriptions.
What is the Bump.sh MCP platform?
Bump.sh describes a managed MCP platform that turns an API ecosystem into hosted MCP servers, with built-in authentication, observability and an MCP preview on every pull request. Basic includes 5 MCP tools, Pro 50 and private MCP servers. Private MCP servers are on Pro.
Can Bump.sh run on premise?
The Custom plan lists an on-premise MCP dataplane, together with SSO, reverse proxy and embed mode and a 99.99% SLA as written on the page. Basic and Pro are hosted, so a team that must keep everything on its own servers should ask sales what is covered.
