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 →

Install

How do I install the MUDD World Sanctuary MCP server?

MUDD World Sanctuary is a hosted endpoint at https://muddworldorg.com/api/agents/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

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.
