IP Address MCP Tools for AI Agents

"Is 192.168.1.256 a valid IP?" An LLM might say yes — after all, it looks like an IP address. But 256 exceeds the valid octet range. IP validation and subnet math require precise rules, not pattern matching. These tools get it right.

All IP Address Tools (16)

Your agent gets access to 16 ip address tools via the /mcp/ip/ endpoint. Here's the complete list:

Tool	Description
`ip/validate`	Validate Ip
`ip/info`	Ip Info
`ip/to-integer`	Ip To Integer
`ip/from-integer`	Integer To Ip
`ip/network`	Network Info
`ip/in-network`	Ip In Network
`ip/subnet`	Subnet Calculator
`ip/supernet`	Supernet Calculator
`ip/range-to-cidr`	Range To Cidr
`ip/expand-cidr`	Expand Cidr
`ip/is-private`	Is Private Ip
`ip/ipv4-to-ipv6`	Ipv4 To Ipv6
`ip/ipv6-to-ipv4`	Ipv6 To Ipv4
`ip/binary`	Ip To Binary
`ip/netmask-to-cidr`	Netmask To Cidr
`ip/cidr-to-netmask`	Cidr To Netmask

Agent Scenarios

Here's how real agents use these tools:

1. Firewall management agent

A security agent validates IP addresses before adding them to allow/deny lists. ip/validate ensures only valid IPs are configured.

Tool Call: ip/validate

{ "ip": "192.168.1.100" }

2. Network planning agent

An infrastructure agent calculates available hosts in a subnet. ip/subnet-info returns network details.

Tool Call: ip/subnet-info

{ "cidr": "10.0.0.0/24" }

3. Access control agent

A security agent checks if a client IP falls within an allowed CIDR range.

Tool Call: ip/in-subnet

{ "ip": "10.0.0.50", "cidr": "10.0.0.0/24" }

MCP Setup

Add ip address tools to your agent in under 2 minutes. Choose your client:

Claude Desktop / Claude Code

Add this to your MCP config:

{
  "mcpServers": {
    "tinyfn-ip": {
      "url": "https://api.tinyfn.io/mcp/ip/",
      "headers": {
        "X-API-Key": "your-api-key"
      }
    }
  }
}

Cursor

Go to Settings > MCP and add a new server:

Type: SSE
URL: https://api.tinyfn.io/mcp/ip/sse
Headers: X-API-Key: your-api-key

Tip: Use the category-specific endpoint (/mcp/ip/) for the best experience. The all-in-one endpoint (/mcp/all/) works too but has 500+ tools which some clients handle less efficiently.

When to Use These Tools

Use ip address MCP tools when your agent needs to:

Guarantee correctness — when wrong answers have real consequences
Process user data — when you're operating on actual user input, not hypothetical examples
Maintain consistency — when the same input must always produce the same output

You don't need these tools for casual conversation or rough estimates. Use them when precision matters.

Frequently Asked Questions

Can LLMs validate IP addresses correctly?

LLMs often fail on edge cases like octet range validation (0-255), IPv6 format rules, and CIDR notation. They rely on pattern matching rather than actual validation logic.

Does TinyFn support IPv6?

Yes. TinyFn validates and processes both IPv4 and IPv6 addresses, including compressed IPv6 notation and IPv4-mapped IPv6 addresses.

What subnet calculations are available?

TinyFn provides subnet info (network address, broadcast, host range, host count), subnet membership checking, and CIDR calculations.
