Token-efficient MCP server for multi-language project analysis (Java, TypeScript, JavaScript, Markdown, Python) with plugins, semantic search, and static analysis.
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.
fast-xml-parser has an entity encoding bypass via regex injection in DOCTYPE entity names
simple-git has blockUnsafeOperationsPlugin bypass via case-insensitive protocol.allow config key enables RCE
When Vitest UI server is listening, arbitrary file can be read and executed
Vitest allows Remote Code Execution when accessing a malicious website while Vitest API server is listening
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
CODEWEAVER_VERBOSETool 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
22/22 tools missing one or more hints — project.meta (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); file.read (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); file.readRange (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +19 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 test coverage
Only 1/22 tools referenced in tests (5%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
32 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
2 critical, 6 high severity in production deps — fast-xml-parser@4.5.0 (critical), simple-git@3.27.0 (critical)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
2 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Dependency freshness
4/17 production deps abandoned (no release in 2+ years): remark-parse@2023-11-20 (2.6y), @xenova/transformers@2024-05-29 (2.1y), cli-table3@2024-05-12 (2.1y)
