Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|

| PORT | No | Listen port (HTTP transports only) | 8000 |
| API_KEY | No | When set, requires X-API-Key header on all HTTP requests | |
| LOG_LEVEL | No | Python log level for process and request logging | INFO |
| MCP_TRANSPORT | No | Transport mode: stdio, streamable-http, or sse | stdio |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| parse_cidrC | Parse a CIDR block and return key network properties. |
| ip_in_subnetC | Check whether an IPv4 address falls within a subnet. |
| subnets_overlapB | Check whether two IPv4 subnets overlap. |
| cidr_to_rangeC | Convert a CIDR block to its first and last IP address. |
| range_to_cidrsA | Convert an inclusive IP address range to the minimal list of covering CIDRs. |
| subtract_subnetC | Subtract one subnet from another and return the remaining address space as CIDRs. |
| find_gapsC | Find unallocated address space within a container block. |
| check_coverageC | Check whether a set of CIDRs fully covers a target block. |

Scored across 11 tools
Each tool has a clearly distinct purpose, from parsing CIDRs (parse_cidr) to checking coverage (check_coverage) and finding gaps (find_gaps). There is no ambiguity or overlap between tool functionalities.
All tool names follow a consistent verb_noun pattern in snake_case (e.g., classify_ip, summarize_cidrs, subtract_subnet), making the set predictable and easy to navigate.
With 11 tools, the server is well-scoped for IP address manipulation tasks. Each tool earns its place, covering essential operations without unnecessary bloat or missing coverage.
The tool set covers the full lifecycle of common IP networking tasks: parsing, conversion, classification, membership checking, coverage analysis, gap detection, overlap checking, subtraction, summarization, and range conversion. No obvious gaps for the domain.
