AI agents call get_sequence_info_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 is a data retrieval tool that provides metadata about plasmid sequences (URLs and availability). It has no side effects, cannot modify data, execute code, delete resources, or commit financial transactions. The read-only nature and limited scope (returns status information) result in low severity even if misused.
From the tool's definition Tool returns 'download URL and availability status' for a specified plasmid ID—it retrieves and queries data without modifying, deleting, or executing operations.
Documented attack patterns abuse exactly the kind of access get_sequence_info_tool gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Addgene, and nothing reaches the server without passing your rules. This is the rule we recommend for get_sequence_info_tool:
{
"version": "1",
"default": "deny",
"tools": {
"get_sequence_info_tool": {}
}
}get_sequence_info_tool is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get information about downloading a plasmid sequence file. Requires a valid Addgene plasmid ID. Returns download URL and availability status. Use EXACTLY format=. It is categorised as a Read tool in the Addgene MCP Server, which means it retrieves data without modifying state.
Register the Addgene MCP server in PolicyLayer and add a rule for get_sequence_info_tool: 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 Addgene. Nothing to install.
get_sequence_info_tool 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 get_sequence_info_tool 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 get_sequence_info_tool. 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.
get_sequence_info_tool is provided by the Addgene MCP server (longevity-genie/addgene-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Addgene, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
