Get the most popular plasmids from Addgene (100+ requests each). This is a convenience method for finding widely-used, well-established plasmids. Returns up to 50 results.
AI agents call get_popular_plasmids_tool to retrieve information from Addgene without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries plasmid metadata from Addgene's repository without creating, modifying, deleting, or executing any code. It is a convenience read-only function that filters publicly available plasmid information. No side effects, no write operations, no code execution, and no financial impact. Severity is low because misuse would only result in retrieving existing public data.
From the tool's definition Tool description states it 'Get[s] the most popular plasmids' and 'Returns up to 50 results' — a data retrieval operation with no modification or deletion capability. The name includes 'get', a read-pattern verb.

{
"version": "1",
"default": "deny",
"tools": {
"get_popular_plasmids_tool": {}
}
}get_popular_plasmids_tool is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
