MCP, MCP server
Mcp Tool Gateway
把 MCP Server 的"裸奔"工具调用变成可控流量。AI 客户端仍然用标准 MCP 协议（Streamable HTTP） 连接网关，但每个工具调用都会经过 API Key 认证 → 权限矩阵（URL 层 + 工具层 + 租户）→ 副作用分级 （READ 直通 / WRITE·DANGEROUS 人工确认）→ 限流 → 事务性审计多道闸门；审计经 Outbox 异步落库， 与业务同事务提交，保证不丢。
Compatibility: Not stated.
Grade B
Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.
Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.
NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV
Why this grade
- NETWORK_NO_FIXED_HOST Low
Makes a network call whose host is not written as a fixed address.
race.sh, line 3
S1=$(curl -s -D - -o /dev/null -X POST http://localhost:8080/mcp \ - NETWORK_UNNAMED_HOST Low
Calls a fixed host that the description does not name.
race.sh, line 3
S1=$(curl -s -D - -o /dev/null -X POST http://localhost:8080/mcp \ - SECRETS_PATH_DOTENV Low
Mentions a .env file.
.dockerignore, line 5
.env
Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.
Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
