Agent Tools

Agent Tools

Agent-native utility API bundle. 9 endpoints exposed as both REST API and MCP server (streamable-http), with x402 micropayments. Live at tools.beethoven2024.com.

For AI agents (Claude, Cursor, custom): Add this MCP server to your config and use 9 utility tools instantly.

For developers: Standard REST API. Use any subdomain example below as a working sample.

Try it now

As MCP server (Claude, Cursor, agents)

{

"mcpServers": { "agent-tools": { "url": "https://tools.beethoven2024.com/mcp" } } }

As REST API

curl https://tools.beethoven2024.com/health

{"status":"ok","version":"0.1.0"}

curl "https://tools.beethoven2024.com/v1/dns/health?domain=example.com"

Full DNS + mail security audit (requires x402 payment)

What's in the bundle

Free: /health, /, /docs (OpenAPI), and MCP protocol methods initialize / tools/list / ping. All 9 tools require x402 payment via both MCP (tools/call) and REST (/v1/*).

Why these endpoints

Every endpoint solves a problem agents can't easily do locally:

• Network infrastructure (DNS, WHOIS, headers, URL health, IP) — needs internet probes, can't be done in-process
• Specialized parsing (QR, email validation with SMTP, tech detection) — domain-specific logic agents shouldn't reimplement
• Web extraction (text extraction) — clean text from messy HTML is hard

8 of 9 endpoints are fully self-hosted (zero upstream API cost). Only IP geolocation uses an external free-tier API.

Payment

x402 (machine-to-machine micropayments)

Every paid endpoint returns HTTP 402 Payment Required with the price spec when no payment is included. x402-capable agents handle this automatically:

1. Agent calls endpoint → receives 402 with payment_requirements (network, amount, recipient address)
2. Agent signs EIP-3009 transferWithAuthorization for USDC on Base
3. Agent retries with X-PAYMENT header
4. Service verifies payment via facilitator, executes, returns result

Settlement happens on-chain on Base. Sub-2-second confirmation.

Runs on Base mainnet by default. Set AGENT_TOOLS_TESTNET=true to use Base Sepolia with the public testnet facilitator.

Traditional billing

Coming soon: API key + Stripe usage billing for human developers and businesses.

Tech stack

• Python 3.12 + FastAPI
• MCP SDK (mcp v1.27) — streamable-http transport
• x402 SDK (x402[fastapi,evm] >=v2.11) — USDC micropayments on Base
• 8/9 endpoints self-hosted (no upstream API cost)
• Single-process deploy, ~62MB memory footprint
