Why Cerul

Web pages are easy for AI agents to search. Video is not.

Most video search today is limited to transcripts — what was said. Cerul goes further by indexing what is shown: slides, charts, product demos, code walkthroughs, whiteboards, and other visual evidence.

[!NOTE] Cerul is in active development. The API is live at cerul.ai — sign up to get a free API key.

Quickstart

Claude Code plugin

Install the official Cerul plugin in Claude Code:

/plugin marketplace add cerul-ai/cerul-plugin-cc
/plugin install cerul@cerul-plugin

Source: cerul-ai/cerul-plugin-cc.

Use with your AI agent

Copy this and send it to your agent (Claude Code, Codex, Cursor, etc.):

Install the Cerul video search skill: mkdir -p ~/.claude/skills/cerul && curl -fsSL https://raw.githubusercontent.com/cerul-ai/cerul/main/skills/cerul/SKILL.md -o ~/.claude/skills/cerul/SKILL.md && cat ~/.claude/skills/cerul/SKILL.md

Your agent will install the CLI, set up credentials, and start searching videos as a tool.

Or install via the skills CLI:

npx skills add cerul-ai/cerul

# Claude Code
mkdir -p ~/.claude/skills/cerul && curl -fsSL https://raw.githubusercontent.com/cerul-ai/cerul/main/skills/cerul/SKILL.md -o ~/.claude/skills/cerul/SKILL.md

# Windsurf
mkdir -p ~/.codeium/windsurf/skills/cerul && curl -fsSL https://raw.githubusercontent.com/cerul-ai/cerul/main/skills/cerul/SKILL.md -o ~/.codeium/windsurf/skills/cerul/SKILL.md

# OpenCode
mkdir -p ~/.config/opencode/skills/cerul && curl -fsSL https://raw.githubusercontent.com/cerul-ai/cerul/main/skills/cerul/SKILL.md -o ~/.config/opencode/skills/cerul/SKILL.md

# Cline / Cursor
mkdir -p .claude/skills/cerul && curl -fsSL https://raw.githubusercontent.com/cerul-ai/cerul/main/skills/cerul/SKILL.md -o .claude/skills/cerul/SKILL.md

CLI

curl -fsSL https://cli.cerul.ai/install.sh | bash
cerul search "Sam Altman on AI video generation tools"

Inline video frame previews are supported in iTerm2, WezTerm, and Kitty. Enable with cerul config and toggle Images on. Other terminals show text-only results.

MCP (Model Context Protocol)

Connect any MCP-compatible client to the hosted endpoint (replace with your API key):

# Claude Code
claude mcp add --transport streamable-http "https://api.cerul.ai/mcp?apiKey=YOUR_API_KEY" cerul

# Codex
codex mcp add --url "https://api.cerul.ai/mcp?apiKey=YOUR_API_KEY" cerul

Also works with Claude Desktop, Cursor, Windsurf, and other MCP clients.

Python

pip install cerul

from cerul import Cerul

client = Cerul(api_key="YOUR_API_KEY")
results = client.search(query="Sam Altman on AGI timeline", max_results=5)

for r in results:
    print(r.title, r.url)

JavaScript

npm install cerul

import { cerul } from "cerul";

const client = cerul({ apiKey: "YOUR_API_KEY" });
const result = await client.search({ query: "Sam Altman on AGI timeline", max_results: 5 });

for (const r of result.results) {
  console.log(r.title, r.url);
}

cURL

curl "https://api.cerul.ai/v1/search" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "Sam Altman on AGI timeline", "max_results": 5}'
