tavern-tanuki (fannnnnnn5822/tavern-tanuki) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: we have no way to read this server ourselves. No publisher has claimed this listing.
MCP server for managing and playing a running SillyTavern instance, enabling AI coding assistants to read/write character cards, worldbooks, and chats, and to interact as a player via the full generation pipeline.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

Install from
M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
SMOKE_CHARST_BRIDGE_PORT环境变量： 可改陪玩桥端口（默认 6700，只监听 127.0.0.1）。ST_PASSWORD"": "basic auth密码"ST_URL"": "http://127.0.0.1:8000",ST_USER"": "basic auth用户名（酒馆没开验证就删掉）",Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
21/21 tools missing one or more hints — st_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_characters (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_character (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +18 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
18/21 tool handlers declare input schemas (86%)
Declare an inputSchema with zod/joi/yup on every tool definition.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
No eval / new Function
1 eval() or new Function() call — dynamic code execution
Replace eval / Function with explicit parsing or safer alternatives.
Shell command execution
2 child_process/subprocess calls in production code — runs shell commands (发版.mjs:12, 发版.mjs:15)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.0 (high), @modelcontextprotocol/sdk@1.12.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
