Octen

npm version npm downloads License: MIT CI

MCP server for Octen. Plug it into Claude, Cursor, VS Code, Windsurf, or any MCP client to give your agent live web search and URL extraction.

Core capabilities:

• search / news_search: search the live web with domain, text, and time filters.
• broad_search: decompose a query into multiple sub-queries, search them concurrently, and return results grouped per sub-query for broad coverage.
• extract: turn one or more URLs into clean, LLM-ready content.
• image_search (In Beta — contact us for beta access): search the web for images by text query, optionally with a reference image.
• video_search (In Beta — contact us for beta access): search the web for videos by text query.

What makes Octen useful for agents is that extract returns more than page text. Each successful result also includes:

• category: what the page is about
• page_structure: what kind of page it is
• highlights: ranked snippets when you pass a query

That lets an agent skip login walls, nav pages, and off-topic URLs before spending tokens on the full body.

Why Octen MCP

Fast

Web search averages 62ms. Fast enough for multi-step MCP workflows.

Accurate

Powered by SOTA text and VL embedding models. Better sources, fewer hallucinations.

Fresh

Live web data with minute-level updates. Useful for news, prices, and fast-moving pages.

Efficient

Clean highlights, optional full_content, and page labels keep model context relevant.

Quick start

You need an OCTEN_API_KEY from octen.ai.

Install in VS Code Install in VS Code Insiders

For most MCP clients, the config is:

{
  "mcpServers": {
    "octen": {
      "command": "npx",
      "args": ["-y", "octen-mcp"],
      "env": {
        "OCTEN_API_KEY": "your-key-here"
      }
    }
  }
}

Install command by client

Agent	One-line install
Claude Code	claude mcp add --scope user octen -e OCTEN_API_KEY=your-key-here -- npx -y octen-mcp
Codex	codex mcp add octen --env OCTEN_API_KEY=your-key-here -- npx -y octen-mcp
Gemini CLI	gemini mcp add octen -e OCTEN_API_KEY=your-key-here -- npx -y octen-mcp
VS Code	code --add-mcp '{"name":"octen","command":"npx","args":["-y","octen-mcp"],"env":{"OCTEN_API_KEY":"your-key-here"}}' (or click a badge above)
Cursor	Add to Cursor (then edit the key), or use the JSON above in ~/.cursor/mcp.json
Claude Desktop	No CLI — add the JSON above to the config file (see below)

Config file locations

For clients without a CLI installer, drop the JSON config above into:

• Claude Desktop: ~/Library/Application\ Support/Claude/claude_desktop_config.json
• Cursor: ~/.cursor/mcp.json
• VS Code workspace: .vscode/mcp.json (use servers instead of mcpServers)
• Windsurf / Cline / other clients: paste it into that client's MCP settings

Tools

Tool	What it does	Best for
search	Search the live web with domain, text, time, and content controls	a single focused web search
news_search	Same engine as search, fixed to news	current events and timely reporting
broad_search	Decompose a query into up to max_queries sub-queries, search concurrently, return grouped results	research-style, multi-angle coverage
extract	Fetch 1-20 URLs and return clean content, labels, and optional highlights	summarization, RAG, fact lookup
image_search	In Beta — contact us for beta access. Search the web for images by text query (optional reference image_url)	finding pictures, photos, visual references
video_search	In Beta — contact us for beta access. Search the web for videos by text query	finding videos, clips, footage

Why agents like this

Most extract tools stop at "here is the page body." Octen helps one step earlier:

• Skip bad pages early: page_structure.primary == "No Main Content" tells the agent it hit a login wall, empty shell, or similar non-content page.
• Filter by topic early: category helps a pipeline ignore pages outside the target vertical before embedding or summarizing.
• Use less context: query returns highlights when the user wants a specific fact instead of the full page.

For the full decision tree and integration patterns, see docs/best-practices.md.

Example prompts

• Fetch octen.ai and summarize the main product features.
• Search for recent MCP news from the last week.
• Fetch these URLs and only summarize the ones whose category is Finance.
• Search site:docs.anthropic.com prompt caching and return only the relevant highlights.

Environment variables
