THE RISK

Low Risk

Why acquire_documents needs a policy

This tool retrieves and queries scientific documents from standard biomedical databases using persistent identifiers. It performs no side effects, does not modify data, execute code, delete content, or transfer funds. The addition of 'provenance and content-level metadata' reinforces that it is a retrieval/analysis tool. No irreversible actions are possible.

From the tool's definition Tool description explicitly states it 'acquires' document text from scientific identifiers (DOI/PMID/PMCID/URL) with metadata. The verb 'acquire' combined with 'fetch' operations on read-only document sources indicates retrieval without modification.

POLICY

How to control acquire_documents

PolicyLayer is an MCP gateway — it sits between your AI agents and MedSci Agent, and nothing reaches the server without passing your rules. This is the rule we recommend for acquire_documents:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "acquire_documents": {}
  }
}

acquire_documents is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register MedSci Agent — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about acquire_documents

What does the acquire_documents tool do? +

Acquire policy-compliant scientific document text from DOI/PMID/PMCID/URL targets with provenance and content-level metadata. It is categorised as a Read tool in the MedSci Agent MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on acquire_documents? +

Register the MedSci Agent MCP server in PolicyLayer and add a rule for acquire_documents: 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 MedSci Agent. Nothing to install.

What risk level is acquire_documents? +

acquire_documents is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit acquire_documents? +

Yes. Add a rate_limit block to the acquire_documents 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.

How do I block acquire_documents completely? +

Set action: deny in the PolicyLayer policy for acquire_documents. 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.

What MCP server provides acquire_documents? +

acquire_documents is provided by the MedSci Agent MCP server (omar-a-hassan/medsci-agent). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every MedSci Agent tool call.

Start from MedSci Agent, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
