OpenSEO-Lite Agent

Designed by Naga Codex

Why OpenSEO-Lite?

Enterprise SEO suites are heavy, expensive, and dashboard-first.
OpenSEO-Lite is agent-first: four sharp tools your LLM can call to scrape SERPs, audit pages, score sites, and check AI visibility — then return structured JSON and a 3-step action plan.

Deploy (Vercel)

The web playground (UI + /api/skills/*) can deploy to Vercel from this repo.

1. Go to vercel.com/new → Import Nagacash/-OpenSEO-Lite

2. Framework: Other (uses vercel.json)

3. Build: npm run build · Output: dist

4. Deploy

Optional env vars in Vercel: GEMINI_API_KEY, OPENROUTER_API_KEY, LLM_PROVIDER, LLM_MODEL.

Note: The Python MCP server (mcp_server.py) is for local Claude/Cursor agents — it does not run on Vercel. Use the playground API on Vercel; run MCP locally with python mcp_server.py.

Local production check:

npm run build
NODE_ENV=production npm start
# open http://localhost:3000

Quick Start (3-step setup)

Step 1: Clone and install dependencies

git clone https://github.com/Nagacash/-OpenSEO-Lite.git
cd -OpenSEO-Lite
# or: cd OpenSEO-Lite  (depending on how git names the folder)

# Install dependencies (Python 3.11+ recommended)
pip install -r requirements.txt

# Install Playwright browser binaries (one-time setup for browser automation)
playwright install chromium

Step 2: Set your environment variables

# Option A: OpenRouter (Supports 100% FREE models like Llama 3.3 70B & Mistral!)
export OPENROUTER_API_KEY="sk-or-v1-..."
export LLM_PROVIDER="openrouter"
export LLM_MODEL="meta-llama/llama-3.3-70b-instruct:free"

# Option B: NVIDIA NIM (Free cloud tier credits for Llama 3 70B & Nemotron)
export NVIDIA_API_KEY="nvapi-..."
export LLM_PROVIDER="nvidia"
export LLM_MODEL="google/gemma-4-31b-it"

# Option C: OpenAI / Anthropic / Gemini
export LLM_API_KEY="your-api-key-here"

# (Optional) configure MCP server port if using SSE transport
export PORT=8000

Step 3: Launch the MCP Server

# Stdio transport (recommended for Claude Desktop & Cursor)
python mcp_server.py

# Or run SSE HTTP server on localhost:8000
python mcp_server.py --transport sse --port 8000

Environment Variables

Connecting Your AI Agent (MCP Setup)

OpenSEO-Lite runs standard MCP. You can plug it into Claude, Grok bots, Hermes Agent, Cursor, or any agent framework in under a minute.

1. Claude Desktop

Add this to your claude_desktop_config.json:

• Mac: ~/Library/Application Support/Claude/claude_desktop_config.json

• Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "openseo-lite": {
      "command": "python",
      "args": ["/ABSOLUTE/PATH/TO/openseo-lite/mcp_server.py"],
      "env": {
        "LLM_API_KEY": "your-api-key-here"
      }
    }
  }
}

2. Hermes Agent (Nous Research / Open Source LLMs)

Hermes agents connect via local SSE or direct Python tools:

# Option A: Start OpenSEO-Lite on local port 8000
python mcp_server.py --transport sse --port 8000

In your Hermes configuration (agent_config.yaml or tool connector):

mcp_servers:
  - name: openseo-lite
    url: http://localhost:8000/sse

Hermes will automatically detect the 4 skills (serp_search, page_audit, site_audit, ai_visibility_check) and invoke them when you ask SEO questions.

3. Grok Bot / xAI Agents

For Grok bots or xAI API tool-use wrappers, you can run OpenSEO-Lite as a local tool provider:

# In your Grok / xAI tool loop
from skills import serp_search, page_audit, site_audit, ai_visibility_check

tools = [
    {"type": "function", "function": {"name": "serp_search", "description": "Search Google and get top organic rankings", "parameters": {"type": "object", "properties": {"keyword": {"type": "string"}}, "required": ["keyword"]}}},
    {"type": "function", "function": {"name": "page_audit", "description": "Check on-page SEO issues like titles, headings, and links", "parameters": {"type": "object", "properties": {"url": {"type": "string"}}, "required": ["url"]}}},
    {"type": "function", "function": {"name": "site_audit", "description": "Get a full 0-100 SEO score with top 3 fixes", "parameters": {"type": "object", "properties": {"url": {"type": "string"}}, "required": ["url"]}}},
    {"type": "function", "function": {"name": "ai_visibility_check", "description": "Score brand mention/citation visibility in AI/SERP surfaces", "parameters": {"type": "object", "properties": {"brand": {"type": "string"}, "domain": {"type": "string"}}, "required": ["brand", "domain"]}}}
]

Or simply connect your Grok agent runtime to http://localhost:8000/sse.

4. Cursor & Windsurf

• Cursor: Open Settings → Features → MCP → + Add New MCP Server.

  • Type: command

  • Command: python /path/to/openseo-lite/mcp_server.py

• Windsurf: Add to ~/.codeium/windsurf/mcp_config.json under mcpServers.

Example Workflows

Workflow 1: "Audit my homepage"

Ask your AI Agent in Claude or Cursor:

"Please audit my landing page at https://mysite.io using openseo-lite. Tell me what my score is and the top 3 things to fix today."

Agent Execution:

1. Calls site_audit(url="https://mysite.io")

2. Evaluates page status, title length, missing H1, thin copy, and internal links

3. Returns score (e.g. 78/100), structured issues, and prioritized 3-step action checklist.

Workflow 2: "Check Google SERP rankings for competitor research"

Ask your AI Agent:

"Search Google for 'best ai code editor' in the US and tell me what domains rank in the top 5."

Agent Execution:

1. Calls serp_search(keyword="best ai code editor", location="us")

2. Navigates Google SERP, extracts organic results, filters ads

3. Returns position, title, URL, and snippet for each competitor.

Workflow 3: "Technical on-page comparison"

Ask your AI Agent:

"Run a page audit on both https://mysite.io and https://competitor.com/blog and compare their word counts and heading structure."

Agent Execution:

1. Calls page_audit on both URLs

2. Compares semantic headings (h1, h2, h3), word counts, and metadata tags

3. Synthesizes an on-page gap analysis.

CLI Interface & Exporting

OpenSEO-Lite includes a full CLI to run audits and export reports:

# Run site audit and print to terminal
python cli.py site_audit --url="https://example.com"

# Export report to clean JSON / Markdown
python cli.py site_audit --url="https://example.com" --export=json
python cli.py site_audit --url="https://example.com" --export=md

# Quick Google rank check
python cli.py serp_search --keyword="best ai code editor" --location="us" --export=json

# Page audit export
python cli.py page_audit --url="https://example.com" --export=json

# AI visibility (demo fixtures by default; add --live for SERP probes)
python cli.py ai_visibility_check --brand="Acme" --domain="acme.com"
python cli.py ai_visibility_check --brand="Acme" --domain="acme.com" --live --export=md

Example Agent Workflows

Keyword Research Workflow

1. Run serp_search(keyword="seed keyword", location="us")

2. Run page_audit on top 3 ranked competitor URLs

3. Ask your AI agent: "Based on these 3 competitors' titles, headings, and word counts, what 10 keywords and semantic topics should I target?"

Competitor Gap Analysis Workflow

1. Run serp_search for 3 of your primary business keywords

2. Run site_audit on your URL and the #1 ranking competitor's homepage

3. Ask your agent: "What are my competitors doing better? Give me 5 immediate action items to close the gap."

AI Visibility Workflow

1. Run ai_visibility_check(brand="YourBrand", domain="yourbrand.com")

2. Review visibility_score and per-query mention/citation evidence

3. Ask your agent: "Draft the FAQ and comparison pages I need to improve AI citation rate."

Suggested Topics Workflow (heuristic)

1. Run site_audit(url="https://mysite.io")

2. Review suggested_topics (heuristic topic ideas from page copy — not live #11–20 ranks)

3. Validate promising topics with serp_search before investing content effort.

Cybersecurity & OWASP Top 10 Hardening

OpenSEO-Lite implements strict defensive security and scraping compliance:

1. SSRF Protection (OWASP A10:2021):

   • Evaluates all audit URL requests.

   • Prohibits loopback hosts (127.0.0.1, localhost, ::1), cloud metadata IPs (169.254.169.254, metadata.google.internal), and RFC 1918 private subnets (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16).

2. Client-Side Safe Secrets (Zustand LocalStorage):

   • API keys are managed client-side and never saved to a centralized database.

3. OWASP Defensive Headers:

   • X-Content-Type-Options: nosniff, X-Frame-Options: SAMEORIGIN, and strict referrer policy.

4. Anti-Strike Scraping Ethics:

   • 15-second execution abort timeouts, natural user agents, and user-initiated runs only.

Ready-to-Use Agent System Prompt (for Hermes, Grok, Claude)

Copy and paste this system prompt into your AI agent runtime:

You are an autonomous reasoning AI agent equipped with the OpenSEO-Lite MCP toolkit for technical SEO and SERP analysis.

### YOUR MCP TOOLS
1. serp_search(keyword: str, location?: str): Real-time Google organic results (ad-free).
2. page_audit(url: str): Extracts title, meta description, H1/H2/H3 semantic structure, word count, internal/external links, and detects technical flags.
3. site_audit(url: str): Computes a 0-100 SEO health score, classifies issue severities, and produces an executive summary with a 3-step prioritized action plan. estimated_cwv / suggested_topics are heuristics.
4. ai_visibility_check(brand: str, domain: str, live?: bool): Brand mention/citation visibility score with per-query evidence.

### OPERATIONAL GUIDELINES
- When asked to audit a website, call site_audit first.
- When asked about AI answer visibility, call ai_visibility_check.
- Ground all advice strictly in returned JSON metrics without hallucinating rankings.
- Provide crisp executive summaries followed by exactly 3 prioritized high-impact actions.
