SpecStream for v0
SpecStream is the live web data engine for teams and agents. Add SpecStream to v0 as a custom MCP server, and v0 can ask for records from the live web while it builds your app, show the price first, and use the rows with their sources.
What you get
- Real data in the first draft
- Ask for yoga studios in Austin with website, address, and class types. v0 gets one record per studio, with the source on every value, and builds the page from them.
- Sign in with OAuth
- The MCP menu takes a custom server with OAuth, a bearer token, or custom headers.
- A price before the run
- The agent brings back the most the request can cost before anything runs, at 5¢, 15¢ or $1 a matching row. A run that finds nothing costs nothing.
Set it up
- In a v0 chat, open the + menu, choose MCPs, and add a custom server.
- Enter the name SpecStream and the URL https://api.specstream.ai/mcp, and choose OAuth.
- Keep the server enabled, then ask.

Live web data, in v0.
Ask in your own words for companies, places, people, filings or anything else the web lists. You see the price before anything runs and pay per match.
