What is the IP Address Parser MCP Server?
A security agent receives the IP 10.0.14.7 and needs to know: is this a private address? Can it reach the internet? What CIDR block does it belong to? Ask an AI and you'll get a confident but often wrong answer.
This MCP uses ipaddr.js (30M+ weekly downloads) — the exact same library that Express.js, Koa, and Fastify use to parse IP addresses in production. Every classification follows RFC 5735 and RFC 4291.
The Superpowers
- Range Classification: Instantly know if an IP is unicast, private, loopback, multicast, linkLocal, or unspecified — no RFC memorization needed.
- CIDR Parsing: Pass
10.0.0.0/8and get the network address, prefix length, and address kind. - Dual Stack: Full IPv4 and IPv6 support with automatic format detection.
- IPv4↔IPv6 Conversion: Convert
192.168.1.1to its IPv4-mapped IPv6 representation::ffff:192.168.1.1and back.
Built-in capabilities (1)
The engine uses ipaddr.js (30M+ downloads) which is the standard IP parsing library used by Express.js and Koa. Validates and parses IPv4/IPv6 addresses. Supports CIDR notation, range detection, and IPv4↔IPv6 conversion
Why Cursor?
Cursor's Agent mode turns IP Address Parser into an in-editor superpower. Ask Cursor to generate code using live data from IP Address Parser and it fetches, processes, and writes. all in a single agentic loop. 1 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.
- —
Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context
- —
Cursor's Composer feature can generate entire files using real-time data fetched through MCP. no copy-pasting from external dashboards
- —
MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment
- —
VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools

Frequently asked questions
How does it know if an IP is private or public?
It follows the IANA reserved ranges defined in RFC 5735 (IPv4) and RFC 4291 (IPv6). 10.x.x.x, 172.16-31.x.x, and 192.168.x.x are classified as 'private'. 127.x.x.x as 'loopback'. Everything else as 'unicast' (public).
Can I check if an IP belongs to a specific CIDR range?
Yes. Pass the CIDR notation like '10.0.0.0/8' and the engine returns the network address, prefix length, and address kind. Parse both the IP and the CIDR to compare.
Does it work with IPv6 addresses?
Yes. Full IPv6 support including compressed notation (::1), IPv4-mapped (::ffff:192.168.1.1), and all RFC 4291 scoped addresses.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
