MCP Paper Finder
MCP server for searching, downloading, and reading academic papers from multiple sources such as arXiv, Google Scholar, and Elsevier.
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.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
xmldom allows multiple root nodes in a DOM
@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
xmldom: Uncontrolled recursion in XML serialization leads to DoS

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
15/15 tools missing one or more hints — arxiv_search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); download_arxiv_paper (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); read_arxiv_paper (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +12 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 handlers catch errors
Only 0/15 tool handlers wrap calls in try/catch (0%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
Only 0/15 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
1 critical, 8 high severity in production deps — xmldom@0.6.0 (critical), @modelcontextprotocol/sdk@1.18.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
