GitHub - brcrusoe72/agent-search: Self-hosted search API ...

🔍 AgentSearch

Self-hosted SearXNG-backed search API and MCP server for AI agents. Drop-in alternative to Tavily/Exa — without the per-query bill or the API key.

AgentSearch wraps SearXNG (an open-source meta-search engine) with a clean FastAPI layer that returns structured JSON. Built for LLM agents, RAG pipelines, and anyone tired of paying per-query for search APIs.

Why?

	AgentSearch	Brave API	Google CSE	SerpAPI
Cost	Free forever	$0.005/query	$5/1K queries	$50/mo
API Key	None	Required	Required	Required
Setup	`docker compose up`	Sign up + wait	Console + billing	Sign up + pay
Engines	6+ (configurable)	Brave only	Google only	Google only
Self-hosted	✅	❌	❌	❌
Rate limits	You control	1 req/sec free	100/day free	100/mo free
Deduplication	Built-in	❌	❌	❌

Integration Examples

Python (requests)

import requests

resp = requests.get("http://localhost:3939/search", params={"q": "latest AI news", "count": 5})
results = resp.json()["results"]
for r in results:
    print(f"{r['title']}: {r['url']}")

LangChain Tool

from langchain.tools import tool
import requests

@tool
def web_search(query: str) -> str:
    """Search the web using AgentSearch."""
    resp = requests.get("http://localhost:3939/search", params={"q": query, "count": 5})
    results = resp.json()["results"]
    return "\n".join(f"- {r['title']}: {r['url']}\n  {r['snippet']}" for r in results)

Python SDK

pip install agentsearch-client

from agentsearch import AgentSearch

client = AgentSearch()  # defaults to localhost:3939
results = client.search("manufacturing OEE best practices")
for r in results:
    print(f"{r.title} — {r.url}")

MCP Server

Use AgentSearch as an MCP tool server — gives any MCP-compatible client (Claude Desktop, Cursor, etc.) access to all 6 tools over stdio.

pip install mcp httpx
python mcp-server/server.py

Add to Claude Desktop config:

{
  "mcpServers": {
    "agent-search": {
      "command": "python",
      "args": ["/path/to/mcp-server/server.py"]
    }
  }
}

See mcp-server/README.md for full setup.
