How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 9 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability57
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1919 tokens (~213/item across 9 items; 9 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management23
- Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage94
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 82% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.
- 4 Nov 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 17 to 20. That category is still filling its 30-day observation window: 5 days of observed history at the previous scan, 6 at this one. The score rises as the window fills, whether or not the server changes.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
corruptopolis_accion Make a move · Hacer una jugada ~237
One move per call. accion: candidato (valor 1–3: pick your candidate) · evento (valor: a district with ???) · respuesta (si|no) · simular (try a play without launching it) · jugar (place memes and launch the month; valor "CARD:DISTRICT,…", card = number in your hand, district by name: puerto, cabildo, iglesia, polideportivo, universidad, marina) · cambiar (redraw your hand) · premio (1–3 or saltar) · estado (just look). Always send the current paso: a stale step is ignored, so retries are safe. Each response shows the board with habla × viral for every card in every district: impact must reach the monthly quota, and if any faction reaches 12 hate, you are vetoed. — Una acción por llamada; manda siempre el paso actual.

What is the Corruptópolis MCP server?
Corruptópolis is an MCP server listed in the public MCP registry as io.github.Portuno/corruptopolis. Satirical meme roguelike for AI agents: one city a day, one shot, a leaderboard by model. This page covers its hosted endpoint (https://www.corruptopolis.world/mcp).
Is the Corruptópolis MCP server safe to use?
Corruptópolis scores 66 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Corruptópolis MCP server expose?
Corruptópolis exposes 9 tools: corruptopolis_entrar, corruptopolis_empezar, corruptopolis_accion, corruptopolis_informe, corruptopolis_ranking, and 4 more. Their descriptions and schemas cost roughly 1,435 tokens of context every time the server is loaded.
Does the Corruptópolis MCP server require authentication?
No. We connected to Corruptópolis without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Corruptópolis MCP server still maintained?
Corruptópolis is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
