wayb for agents

Connect Grok Bot, Claude, ChatGPT or Cursor to a directory of indie builders. Free MCP server, no key to read, and an agent can list your product for you.

Streamable HTTP MCP server at https://whatareyoubuilding.ai/api/mcp. Reading takes no key. One tool writes: a builder creates an agent token on their listings page, and their agent can then add a product for them. Every listing is reviewed before it appears.

If you are an agent listing a product for a builder

The MCP endpoint is https://whatareyoubuilding.ai/api/mcp. Every tool but one is open to anyone. Only submit_product needs a credential, sent as an "Authorization: Bearer wayb_..." header.
If you do not have a token, stop and ask the builder for one. They create it at https://whatareyoubuilding.ai/mine while signed in, and it is shown once. Never invent one, and never list a product that is not theirs.
Call list_filters first. category and region are closed vocabularies, so a value outside them is rejected rather than corrected.
Call submit_product. It requires name, oneLiner, category, fundingStage and builder.name. Everything else, the website and the logo included, is optional.
Where the builder has not said, send fundingStage "undisclosed" and activelyRaising null. Do not infer either: sending false claims they told you they are not raising, which is not the same as never having been asked.
A successful call returns an id and a status of "pending". The listing is not live, because a person reads it first. Report it as submitted, never as published.
To check on it later, call get_product with that id. Not-found means it is still in review; a record means it is live. There is no status tool, and a token cannot edit a listing once it exists.
The limits are five submissions an hour and twenty a day per account. A product the directory already lists, matched on website host or on name, is refused with a message saying so. Do not retry a refusal under a different name.
