Why start free on SpecStream
One line in Claude Code, and no key in a file
Run this in Claude Code and sign in to SpecStream when the browser opens. The client holds the sign in, so no key sits in a config file:
claude mcp add --transport http specstream https://api.specstream.ai/mcpYour agent finds search_web, read_pages and the Deep Search tools with tools/list. Cursor, VS Code, ChatGPT and the other clients take the same address, and the MCP client guides show where each one keeps it.
$10 of credit, and the same search a paying account gets
A new account starts with $10 of credit and no card. That covers 10,000 fast searches of up to 10 results at $1 per 1,000, or 2,000 searches that also return the answer at $5 per 1,000. A search that returns nothing costs nothing, and each API key carries the spending limit you give it.
search_web runs SpecStream's Search API. It scores 97.9 F-score on all 1,000 official SimpleQA Verified questions (978 correct), and 64.0 item F1 and 43.4 row F1 on all 200 official WideSearch tasks. The Extract API behind read_pages scores 0.908 F1 on WCXB. The scores and the method are on the benchmarks page.
Your credit, not a daily allowance
Keyless servers stop at a rate limit, and of the five hosted ones only You.com prints its number. A DuckDuckGo server stops when DuckDuckGo answers its client with an empty page. A SpecStream search runs on SpecStream's servers across several search engines and is paid from your credit, so the limit is the one you set on the key.
Pages and rows from the same server
read_pages reads up to 20 URLs a call, PDF, Word and Excel files included, at $0.80 per 1,000 pages, and a page with no text is not charged. When the job is a list, the same connection runs Deep Search: compile reads the request into conditions and facts, quote_capacity_work prices it, and authorize_capacity_work runs it under the maximum you approve. Rows cost 5¢, 15¢ or $1 each, with the source URL and read time on every value.
Other free web search MCP servers
Brave Search MCP
Brave's official server runs on your machine from @brave/brave-search-mcp-server and needs a BRAVE_API_KEY. The Search API costs $5 per 1,000 requests and includes $5 in free credits every month, about 1,000 searches. SpecStream's $10 of credit covers 10,000 fast searches, with page reading on the same server.
SearXNG MCP
mcp-searxng gives your agent searxng_web_search against the SearXNG instance you name in SEARXNG_URL. The instance must answer in JSON: SearXNG's docs say an unset format returns 403 Forbidden and that many public instances have it turned off. SpecStream answers SearXNG's own address too, so a tool built for SearXNG works with no server to run. See moving off SearXNG.
The paid servers
Web search MCP servers in 2026 puts SpecStream, Exa, Tavily, Brave, Firecrawl, Parallel and Perplexity side by side by endpoint, tools and price per 1,000 searches.

How to start free
1. Sign up at specstream.ai. The account starts with $10 of credit, no card.
2. In Claude Code, add the server and sign in when the browser opens:
claude mcp add --transport http specstream https://api.specstream.ai/mcp3. In Cursor, create a key under Agents & API in the workspace, give it a spending limit, put it in SPECSTREAM_API_KEY, and add this to mcp.json:
{
"mcpServers": {
"specstream": {
"url": "https://api.specstream.ai/mcp",
"headers": { "Authorization": "Bearer ${env:SPECSTREAM_API_KEY}" }
}
}
}4. Ask your agent a question that needs the live web. It calls search_web, and reads the pages it needs with read_pages.
