Bump vs Stoplight

Bump scores higher on the AgentReady, 52/100 against 48/100. They differ on 11 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Bump. Bump.sh is a platform for API documentation and MCP (Model Context Protocol) servers that automatically generates docs and production-ready MCP servers from OpenAPI, AsyncAPI, and Arazzo specifications.

Stoplight. Stoplight is a collaborative platform equipping teams with tooling across the API lifecycle to help them build quality APIs efficiently.

Where Bump is ahead

Bump passes clear product positioning and mcp discoverable, and Stoplight does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: authentication documented. Stoplight misses it.

And on adopt, copyable quickstart and mcp integration available. Stoplight misses those.

Finally, on operate, retry behavior documented. Stoplight misses it.

Where Stoplight is ahead

Stoplight passes pricing understandable, and Bump does not. That is understand, whether an agent can read the docs and work out how the API behaves before calling it.

It also holds adopt: self-service signup, agent-compatible signup flow and free trial or free allowance. Bump misses those.

And on operate, structured, predictable output. Bump misses it.

What neither does

Both fail clear canonical domain, llms.txt published, llms-full.txt / full agent docs, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, no mandatory sales call, programmatic credential creation, fast time to first request, machine-readable errors, idempotency support, rate-limit behavior predictable, agent compatibility verified. If your agent needs any of those, you will be building it yourself either way.

Score, pillar by pillar

The AgentReady splits into four pillars, scored separately, because a product can be easy to find and still impossible to adopt.

Discover is whether an agent can find the product at all without being told it exists. Bump leads 80 to 53. Bump misses clear canonical domain, llms.txt published, llms-full.txt / full agent docs; Stoplight misses clear canonical domain, clear product positioning, llms.txt published, llms-full.txt / full agent docs, mcp discoverable.

Understand. Both sit at 38/100 here. Bump misses openapi / spec quality, pricing understandable, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; Stoplight misses openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented.

Adopt. Stoplight leads 55 to 45. Bump misses self-service signup, no mandatory sales call, agent-compatible signup flow, programmatic credential creation, free trial or free allowance, fast time to first request; Stoplight misses no mandatory sales call, programmatic credential creation, fast time to first request, copyable quickstart, mcp integration available.

Operate. Stoplight leads 47 to 44. Bump misses structured, predictable output, machine-readable errors, idempotency support, rate-limit behavior predictable, agent compatibility verified; Stoplight misses machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified.

Pricing

Bump does not publish a machine-readable starting price. Stoplight starts at $44/mo and has a free tier.
