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.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
uuid: Missing buffer bounds check in v3/v5/v6 when buf is provided

KAGI_DEFAULT_MODELDefault model to use (optional, uses first from list if not specified)KAGI_MODEL_LISTComma-separated list of available AI models (required for assistant)KAGI_SEARCH_COOKIEYour _kagi_search_ cookie valueKAGI_SESSION_TOKENYour Kagi session tokenKAGI_SUMMARIZER_ENGINESummarizer engine to use (optional, default: "default")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
3/3 tools missing one or more hints — kagi_search_fetch (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); kagi_summarizer (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); kagi_assistant (missing: readOnlyHint, destructiveHint, 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 0/3 tool handlers declare input schemas (0%)
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.
Production dependencies are patched
0 critical, 1 high severity in production deps — @modelcontextprotocol/sdk@1.0.0 (high), uuid@13.0.0 (low)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Domain consistency
npm scope @duange doesn't match GitHub owner z23cc
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
