Features

• Multi-Engine Search: Google, Bing, Yahoo, DuckDuckGo, YouTube, eBay, and more
• Engine Resources: Per-engine parameter schemas available via MCP resources (see Search Tool)
• Real-time Weather Data: Location-based weather with forecasts via search queries
• Stock Market Data: Company financials and market data through search integration
• Dynamic Result Processing: Automatically detects and formats different result types
• Flexible Response Modes: Complete or compact JSON responses
• JSON Responses (default): Structured JSON output with complete or compact modes
• Markdown Responses: Cut token usage by 50% on average and by more than 90% for APIs with complex nested JSON.
• Interactive UI (MCP Apps): Opt-in search_table and search_dashboard tools that render results as an interactive UI in supporting hosts

Quick Start

SerpApi MCP Server is available as a hosted service at mcp.serpapi.com. In order to connect to it, you need to provide an API key. You can find your API key on your SerpApi dashboard.

You can configure Claude Desktop to use the hosted server:

{
  "mcpServers": {
    "serpapi": {
      "type": "http",
      "url": "https://mcp.serpapi.com/YOUR_SERPAPI_API_KEY/mcp"
    }
  }
}

You can also add the hosted server to these MCP clients:

OpenClaw

openclaw mcp add serpapi --url https://mcp.serpapi.com/YOUR_SERPAPI_API_KEY/mcp --transport streamable-http

Claude Code

claude mcp add --transport http serpapi https://mcp.serpapi.com/YOUR_SERPAPI_API_KEY/mcp

Hermes

hermes mcp add serpapi --url https://mcp.serpapi.com/YOUR_SERPAPI_API_KEY/mcp

Codex

codex mcp add serpapi --url https://mcp.serpapi.com/YOUR_SERPAPI_API_KEY/mcp

Self-Hosting

git clone https://github.com/serpapi/serpapi-mcp.git
cd serpapi-mcp
uv sync && uv run src/server.py

Configure Claude Desktop:

{
  "mcpServers": {
    "serpapi": {
      "type": "http",
      "url": "http://localhost:8000/YOUR_SERPAPI_API_KEY/mcp"
    }
  }
}

Get your API key: serpapi.com/manage-api-key

Authentication

Two methods are supported:

• Path-based: /YOUR_API_KEY/mcp (recommended)
• Header-based: Authorization: Bearer YOUR_API_KEY

Examples:

# Path-based
curl "https://mcp.serpapi.com/your_key/mcp" -d '...'

# Header-based  
curl "https://mcp.serpapi.com/mcp" -H "Authorization: Bearer your_key" -d '...'

Search Tool

The MCP server has one main Search Tool that supports all SerpApi engines and result types. You can find all available parameters on the SerpApi API reference. Engine parameter schemas are also exposed as MCP resources: serpapi://engines (index) and serpapi://engines/<engine>.

The parameters you can provide are specific for each API engine. Some sample parameters are provided below:

• params.q (required): Search query
• params.engine: Search engine (default: "google_light")
• params.location: Geographic filter
• params.output: Response format; omit for JSON (default), or set to "md" for Markdown
• mode: Response mode; "compact" removes metadata from JSON, while Markdown is returned unchanged
• ...see other parameters on the SerpApi API reference

Examples:

{"name": "search", "arguments": {"params": {"q": "coffee shops", "location": "Austin, TX"}}}
{"name": "search", "arguments": {"params": {"q": "weather in London"}}}
{"name": "search", "arguments": {"params": {"q": "AAPL stock"}}}
{"name": "search", "arguments": {"params": {"q": "news"}, "mode": "compact"}}
{"name": "search", "arguments": {"params": {"q": "detailed search"}, "mode": "complete"}}
{"name": "search", "arguments": {"params": {"q": "news", "output": "md"}}}
{"name": "search", "arguments": {"params": {"engine": "amazon", "k": "mechanical keyboards", "amazon_domain": "amazon.com", "output": "md"}}}
{"name": "search", "arguments": {"params": {"engine": "google_scholar", "q": "retrieval augmented generation"}}}
{"name": "search", "arguments": {"params": {"engine": "youtube", "search_query": "how to make espresso"}}}
{"name": "search", "arguments": {"params": {"engine": "apple_app_store", "term": "habit tracker"}}}
{"name": "search", "arguments": {"params": {"engine": "ebay", "_nkw": "vintage mechanical keyboard"}}}

Supported Engines: Google, Bing, Yahoo, DuckDuckGo, YouTube, eBay, and more (see serpapi://engines).

Result Types: Answer boxes, organic results, news, images, shopping - automatically detected and formatted.

Interactive UI (MCP Apps)

The default search tool returns JSON and is unchanged. For hosts that support the MCP Apps extension (SEP-1865), two opt-in tools render results as an interactive UI directly in the conversation, so the bulk SERP JSON never enters the model's context window:

• search_table: organic results as a sortable, searchable table.
• search_dashboard: summary metrics, a source-breakdown chart, and a results table with a click-to-expand detail panel.

Both accept the same params as search. Hosts that don't support MCP Apps simply ignore these tools.

Preview them locally without an MCP host:

uv run fastmcp dev apps src/server.py

Development

# Local development
uv sync && uv run src/server.py

# Docker
docker build -t serpapi-mcp . && docker run -p 8000:8000 serpapi-mcp

# Regenerate engine resources (Playground scrape)
python build-engines.py

# Testing with MCP Inspector
npx @modelcontextprotocol/inspector
# Configure: URL mcp.serpapi.com/YOUR_KEY/mcp, Transport "Streamable HTTP transport"

Troubleshooting

• "Missing API key": Include key in URL path /{YOUR_KEY}/mcp or header Bearer YOUR_KEY
• "Invalid key": Verify at serpapi.com/dashboard
• "Rate limit exceeded": Wait or upgrade your SerpApi plan
• "No results": Try different query or engine
