These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.
AuthorizationValues marked secret are keys to your account. Never share them or paste them into a chat.

Which app do you use?
Pick your app above. We remember it, so next time the button says “Install in …”.
This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.
Run this in your terminal
claude mcp add --transport http specstream https://api.specstream.ai/mcp --header 'Authorization: Bearer {api_key}'Fill in the empty values before running it.
Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

"headers": {
"Authorization": "Bearer {api_key}"

}Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (1.3.2) reached the registry yesterday.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

The live web data engine for teams and agents.
Website · Docs · Pricing · MCP Registry
One platform to build, search, extract, enrich, map, and monitor data across the entire web.
Ask for any dataset in plain words, and SpecStream builds it from the entire live web: every match found, extracted and enriched into structured records, then monitored for change. It runs through the API and MCP, and inside Sheets, CRMs, Slack, n8n, Zapier and the other tools teams already use.
| Product | What it does | Price |
|---|---|---|
| Search API | GET /v1/web-search. The most accurate web search API in the world (scores and method). Answers a question from the live web in seconds. | $5 per 1,000 searches |
| Extract API | POST /v1/extract. The main text of up to 20 web pages, PDF, Word or Excel files a call. The MCP tool is read_pages. | $0.80 per 1,000 pages. A page with no text is not charged. |
| Deep Search | Ask in plain words. Get every match on the live web, in structured rows. It also enriches a list you have and monitors for change. | 5¢, 15¢ or $1 a row |
Search:
curl -G https://api.specstream.ai/v1/web-search \
-H "Authorization: Bearer $SPECSTREAM_API_KEY" \ --data-urlencode "q=What is the population of Japan?"
Extract:
curl https://api.specstream.ai/v1/extract \
-H "Authorization: Bearer $SPECSTREAM_API_KEY" \ -H "Content-Type: application/json" \ -d '{"urls": ["https://example.com"]}'
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.

The MCP server is https://api.specstream.ai/mcp (Streamable HTTP). Your agent works on your account: the same balance, permissions and spending limits you have.
export SPECSTREAM_API_KEY="ss_live_..."
Clients that support MCP sign-in can connect without a key. Each guide at specstream.ai/docs/mcp shows the current steps.
New accounts start with $10 of credit for 30 days, no card.
In Claude, go to Customize > Connectors, choose Add custom connector, name it SpecStream and paste https://api.specstream.ai/mcp. Steps for both sign-in and a key: docs/mcp/claude.
claude mcp add --transport http specstream https://api.specstream.ai/mcp \
--header "Authorization: Bearer $SPECSTREAM_API_KEY"
Or install the plugin, which adds the server and the six skills. It signs you in through your browser the first time, so no key is needed:
/plugin marketplace add specstream/specstream-tools
/plugin install specstream@specstream
Go to ChatGPT Plugins, choose the plus button, then Add custom MCP server. Paste https://api.specstream.ai/mcp under Connection and set Authentication to OAuth. Steps: docs/mcp/chatgpt.
Add to ~/.codex/config.toml:
[mcp_servers.specstream]
url = "https://api.specstream.ai/mcp" bearer_token_env_var = "SPECSTREAM_API_KEY"
Add to ~/.cursor/mcp.json, or .cursor/mcp.json in one project:
{
"mcpServers": { "specstream": { "url": "https://api.specstream.ai/mcp", "headers": { "Authorization": "Bearer ${env:SPECSTREAM_API_KEY}" } } } }
Add to .vscode/mcp.json. VS Code asks for the key once and keeps it out of the file.
{
"inputs": [ { "type": "promptString", "id": "specstream-key", "description": "SpecStream API key", "password": true } ], "servers": { "specstream": { "type": "http", "url": "https://api.specstream.ai/mcp", "headers": { "Authorization": "Bearer ${input:specstream-key}" } } } }
Add to ~/.codeium/windsurf/mcp_config.json:
{
"mcpServers": { "specstream": { "serverUrl": "https://api.specstream.ai/mcp", "headers": { "Authorization": "Bearer ${env:SPECSTREAM_API_KEY}" } } } }
Cline also connects to the hosted server directly with OAuth sign-in: cline mcp install specstream --transport http https://api.specstream.ai/mcp. Zed and Continue, and Cline if you prefer a key, use the stdio proxy. It forwards your key from the environment and nothing else.
pip install specstream-mcp-stdio
Zed, in settings.json:
{
"context_servers": { "specstream": { "command": "specstream-mcp-stdio", "args": [], "env": { "SPECSTREAM_MCP_URL": "https://api.specstream.ai/mcp" } } } }
Cline, in cline_mcp_settings.json:
{
"mcpServers": { "specstream": { "command": "specstream-mcp-stdio", "args": [], "env": { "SPECSTREAM_MCP_URL": "https://api.specstream.ai/mcp" } } } }
Continue, in .continue/mcpServers/specstream.yaml:
name: SpecStream
version: 1.0.0 schema: v1 mcpServers:
Start Zed and Cline from a shell where SPECSTREAM_API_KEY is set. Agents installing SpecStream for someone can follow llms-install.md.
Install the extension (the MCP server plus instructions to show the price and wait for a yes):
gemini extensions install https://github.com/specstream/specstream-tools
Or add only the server:
gemini mcp add --transport http specstream https://api.specstream.ai/mcp \
--header "Authorization: Bearer $SPECSTREAM_API_KEY"
Or in ~/.gemini/settings.json:
