Give your AI agent web search across 6 engines through one MCP search tool. Hosted. Routed. Cached.

Why GroundRoute

One tool, six engines. Serper, Brave, Exa, Tavily, Firecrawl, Perplexity, behind a single search call. Stop wiring up six APIs, six SDKs, six billing portals.
Never more than going direct. Gain-share pricing: you keep ~half of every cache saving, GroundRoute keeps ~half. On a miss, you just pay the engine. BYOK supported.
Routing, caching, failover, on by default. Each query goes to the cheapest engine that clears a quality bar. Repeats serve from cache. If an engine degrades, we fall back automatically. No agent code changes.

A call to the search tool:

json

{
  "name": "search",
  "arguments": { "query": "what is RAGflow", "max_results": 3 }
}

The response (trimmed):

json

{
  "results": [
    {
      "url": "https://ragflow.io/docs/",
      "title": "Quickstart - RAGFlow",
      "snippet": "RAGFlow is an open-source RAG engine based on deep document understanding...",
      "source_engine": "serper"
    },
    {
      "url": "https://github.com/infiniflow/ragflow",
      "title": "RAGFlow is a leading open-source Retrieval-Augmented Generation engine",
      "snippet": "RAGFlow is a leading open-source Retrieval-Augmented Generation (RAG) engine...",
      "source_engine": "serper"
    }
  ],
  "meta": {
    "request_id": "req_abc123",
    "cache_tier": "miss",
    "degraded": false,
    "cost_usd": 0.0021
  }
}

source_engine tells you which engine answered. meta exposes the cache tier and billed cost per call.

Benchmarked, not just shipped

We ran 170 real agent queries across all 6 engines, judged by an LLM, to map cost vs. quality per query class. Full methodology and per-engine results: State of AI Search.

Install

The hosted endpoint is https://api.groundroute.ai/mcp (streamable-HTTP). Get an API key at groundroute.ai/keys.

Claude Desktop / Claude Code, add to your MCP config:

json

{
  "mcpServers": {
    "groundroute": {
      "type": "http",
      "url": "https://api.groundroute.ai/mcp",
      "headers": { "Authorization": "Bearer gr_YOUR_KEY" }
    }
  }
}

Cursor, ~/.cursor/mcp.json:

json

{ "mcpServers": { "groundroute": { "url": "https://api.groundroute.ai/mcp",
  "headers": { "Authorization": "Bearer gr_YOUR_KEY" } } } }

VS Code (native MCP / Continue), .vscode/mcp.json:

json

{ "servers": { "groundroute": { "type": "http", "url": "https://api.groundroute.ai/mcp",
  "headers": { "Authorization": "Bearer gr_YOUR_KEY" } } } }

Local / stdio-only clients, bridge stdio to HTTP with mcp-remote:

json

{ "mcpServers": { "groundroute": {
  "command": "npx",
  "args": ["-y", "mcp-remote", "https://api.groundroute.ai/mcp", "--header", "Authorization:Bearer gr_YOUR_KEY"]
} } }

Run this repo's stdio server (optional)

This repo also ships a small native stdio MCP server (server.py) that forwards to the hosted API, useful for stdio-only clients or containerized runs.

bash

pip install -r requirements.txt
GROUNDROUTE_API_KEY=gr_YOUR_KEY python server.py

Or with Docker:

bash

docker build -t groundroute-mcp .
docker run -i -e GROUNDROUTE_API_KEY=gr_YOUR_KEY groundroute-mcp

Introspection (tool discovery) works with no key; running a search requires GROUNDROUTE_API_KEY (get one at https://groundroute.ai/keys).

The `search` tool

Param	Type	Notes
`query`	string	required
`mode`	enum	`auto` (default), `web`, `news`, `academic`, `answer`, `page`
`max_results`	integer	default 10, max 50
`freshness`	enum	`fresh`, `semi`, `static`; omit to auto-detect
`domains`	string[]	include-only domain filter, e.g. `["arxiv.org"]`
`lang`	string	ISO 639-1 language code, e.g. `en`
`country`	string	ISO 3166-1 alpha-2 country code, e.g. `us`

Returns a structured result: ranked results (url / title / snippet / content / source_engine / published_at), an optional synthesized answer with citations (answer mode), and meta (request_id / cache_tier / degraded / cost_usd). Routed, cached, and reliable.

How it works

One endpoint in front of many search engines, with price-led routing, caching, failover, and usage governance. See the docs and the State of AI Search benchmark (170 real agent queries across all 6 engines).
