mcp-auth-kit (bradburch/mcp-auth-kit) 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.
A production-minded MCP server kit that provides OAuth 2.1/PKCE authentication, rate limiting, scope-gated tools, and two-phase confirmation for building secure MCP servers with custom tools, identity, and storage.
Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. 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.

All four hints declared on every tool
1/1 tools missing one or more hints — confirm_request (missing: readOnlyHint, idempotentHint, openWorldHint). 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
Only 0/1 tool handlers declare input schemas (0%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Dev dependencies
7 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
