What the publisher says

From the SpecStream repository's README, as published. We do not edit it. Read it on GitHub

The live web data engine for teams and agents.

Website  ·  Docs  ·  Pricing  ·  MCP Registry

Finished lists from the live web for your agent, every row with its source, priced before anything runs. Ask for the list you need in plain words and get all of it: only the matches, each with the page it came from, kept current and sent where you work. You pay only for the matches.

Your agent asks for "food banks in Texas, with their annual revenue" and gets rows it can cite, each with the page behind it. It sees the price first, and a search that finds nothing costs nothing.

This repository holds what you install around SpecStream: MCP client setup, agent plugins and skills, SDKs, the n8n node, a GitHub Action, and examples. The product itself runs at specstream.ai. Licensed MIT.

Connect an agent

The MCP server is https://api.specstream.ai/mcp (Streamable HTTP, 97 tools). Your agent works on your account: the same balance, permissions and spending limits you have.

  1. Open Agents & API in the workspace and create an API key. Give it only what the task needs: read, prepare, or execute, the projects it may use, an expiry, and a spending limit.
  2. Put it in an environment variable, so no file holds it:
export SPECSTREAM_API_KEY="ss_live_..."
  1. Add the server to your client, below.

Shortened. The full README is on GitHub.
