An MCP server that provides tools for getting second opinions or detailed code reviews from Gemini 2.5 Pro by embedding file contents in prompts, allowing it to handle large codebases with extensive context.
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
glob CLI: Command injection via -c/--cmd executes matches with shell:true
js-yaml: YAML merge-key chains can force quadratic CPU consumption
ANTHROPIC_API_KEYYour Anthropic API key (for Claude Opus 4.1)GEMINI_API_KEYFor medium contexts (≤ 1M tokens): Uses Google's Gemini 2.5 Pro (if is set)OPENAI_API_KEYFor smaller contexts (≤ 400K tokens): Uses OpenAI's GPT-5 (if is set)SAGE_TELEMETRYSKIP_API_CALLSTool 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
2/2 tools missing one or more hints — sage-opinion (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); sage-review (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
1/2 tool handlers declare input schemas (50%)
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.).
Secrets stay with their owner
2 secret/sensitive values flow into network calls (GEMINI_API_KEY → dynamic, GEMINI_API_KEY → dynamic)
Audit where credentials are sent. A NOTION_TOKEN should only reach api.notion.com — never a third-party host.
Secrets not written to files
1 secret value written to files
Avoid persisting secrets to disk. Keep them in memory or your secret manager.
Secrets not logged
3 secret values sent to console.log
Redact or omit secret values from log output.
Production dependencies are patched
0 critical, 6 high severity in production deps — @modelcontextprotocol/sdk@1.10.0 (high), @modelcontextprotocol/sdk@1.10.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

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.
