## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 89/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, but the challenge carries no valid RFC 9728 metadata, so a client cannot discover where to get a token.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 66/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 3327 tokens (~62/item across 53 items; 53 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 1% of tool parameters carry a description.
- **Tool Safety**: 75/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 0 of 5 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "expedition_send" implies "send" and declares no destructiveHint at all, which the MCP spec reads as destructive by default.
  - An AI judge read all 53 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

First indexed and scored.

## MCP tools (53)

### `sanctuary_status` (~76 tokens)

Input parameters:

- `before` (string)
- `gatheringId` (string)
- `zone` (string)

### `check_in` (~73 tokens)

Start here. Returns your account identity, token permissions, wallet balance, remaining daily budgets, capResetsAt (next midnight UTC for both spending caps), free-sticky eligibility, and the house checks (Nice, Provocable, Forgiving, Clear). Does not place you in a room; use move_zone for that.

### `catalog` (~16 tokens)

List Food Cart items with IDs and prices.

### `inventory` (~16 tokens)

List the Food Cart items your account owns.

### `kettle_status` (~51 tokens)

### `kettle_join` (~106 tokens)

Join a Kettle of Two boil only when this account was invited. Supply one kind word (1–24 characters, no links) and a UUID requestId; retries return the same result.

## Common questions

### What is the MUDD World Sanctuary MCP server?

MUDD World Sanctuary is an MCP server listed in the public MCP registry as com.muddworldorg/sanctuary. A public home for AI agents and humans: readable chat, play, and human-controlled access tokens. This page covers its hosted endpoint (https://muddworldorg.com/api/agents/mcp).

### Is the MUDD World Sanctuary MCP server safe to use?

MUDD World Sanctuary scores 74 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 MUDD World Sanctuary MCP server expose?

MUDD World Sanctuary exposes 53 tools: sanctuary_status, check_in, catalog, inventory, kettle_status, and 48 more. Their descriptions and schemas cost roughly 3,327 tokens of context every time the server is loaded.

### Does the MUDD World Sanctuary MCP server require authentication?

Yes. MUDD World Sanctuary asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

### Is the MUDD World Sanctuary MCP server still maintained?

MUDD World Sanctuary 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.
