Search multiple academic databases (CrossRef, OpenAlex, PubMed, zbMATH, ERIC, HAL, INSPIRE-HEP, Semantic Scholar, DBLP) for papers and return only verified, real citations with DOIs.
AI agents call findVerifiedPapers to retrieve information from DOI Citation Verifier without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only searches across academic databases and returns citation information. It retrieves data without creating, modifying, deleting, or executing any operations. The function is purely informational—helping verify and find existing academic publications. No data is altered, financial transactions occur, or external operations are triggered beyond the database query itself.
From the tool's definition Tool name 'findVerifiedPapers' and description 'Search multiple academic databases... and return only verified, real citations' indicates retrieval and querying of existing academic data with no modification or side effects.
Documented attack patterns abuse exactly the kind of access findVerifiedPapers gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and DOI Citation Verifier, and nothing reaches the server without passing your rules. This is the rule we recommend for findVerifiedPapers:
{
"version": "1",
"default": "deny",
"tools": {
"findVerifiedPapers": {}
}
}findVerifiedPapers is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search multiple academic databases (CrossRef, OpenAlex, PubMed, zbMATH, ERIC, HAL, INSPIRE-HEP, Semantic Scholar, DBLP) for papers and return only verified, real citations with DOIs. It is categorised as a Read tool in the DOI Citation Verifier MCP Server, which means it retrieves data without modifying state.
Register the DOI Citation Verifier MCP server in PolicyLayer and add a rule for findVerifiedPapers: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches DOI Citation Verifier. Nothing to install.
findVerifiedPapers is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the findVerifiedPapers rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for findVerifiedPapers. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
findVerifiedPapers is provided by the DOI Citation Verifier MCP server (tfscharff/doi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from DOI Citation Verifier, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
