Dechonet MCP

My IP Info

ip_info

Read-onlyIdempotent

Report the MCP server's egress public IP (IPv4/IPv6), ISP, ASN, geolocation, and proxy/VPN signals to identify outbound connectivity.

Instructions

Report information about the caller's own public IP as seen by the server: IPv4/IPv6 address, ISP, ASN, approximate geolocation, and proxy/VPN heuristics. Takes no input — it reflects the egress IP of THIS MCP server's network, which is usually NOT the end user's IP. Use this to discover the server's outbound IP or test connectivity. To inspect a specific, known IP instead, use asn_lookup or reverse_dns. Read-only; requires no API key; rate-limited.

Name	Required	Description
`kpis`	No	Key metrics as label/value pairs
`grade`	No	Letter grade (A+ to F) when the tool grades the target
`score`	No	0-100 score when the tool scores the target

`actions`	No	Recommended next actions, most important first
`summary`	No	One-paragraph interpretation of the result
`receipts`	No	Signed observation receipts behind this result, one per lookup: when, from where and under which rules version DechoNet observed it. Each url shows the record and checks its Ed25519 signature.

TDQS

A4.9/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already cover read-only, idempotent, open-world, and non-destructive behavior, while the description adds operational context beyond them: no input, no API key, rate limiting, and the important caveat that this reflects the MCP server's network egress IP. This extra context helps an agent interpret the result correctly.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loads the purpose and field list, then adds the no-input clarification, usage guidance, alternatives, and operational traits. The sentences are short and earn their place, with only minor redundancy in restating read-only.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple no-parameter read tool with rich annotations and an output schema, the description is complete: it explains result type, the server-egress nuance, alternatives, and operational constraints. Return-value details are appropriately left to the output schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters, and the description confirms this by saying it takes no input. With no parameter semantics to clarify, the baseline for a zero-parameter tool is 4.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource: reports the caller's own public IP as seen by the server, enumerating fields such as IPv4/IPv6, ISP, ASN, geolocation, and proxy/VPN heuristics. It explicitly distinguishes itself from asn_lookup and reverse_dns, which inspect a specific known IP instead.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides clear when-to-use: discover the server's outbound IP or test connectivity. It also gives the alternative when a specific known IP must be inspected, naming asn_lookup and reverse_dns, and warns that the result is the server's egress IP rather than the end user's IP.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
