What get_source does on OrigeneMCP
AI agents call get_source to retrieve information from OrigeneMCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why get_source is rated Low
This tool retrieves or queries data (a source object list) from the biomedical database without side effects, reversible modifications, or irreversible actions. It is a standard Read operation typical of data retrieval in research databases. The low severity reflects minimal blast radius—misuse would only retrieve information without affecting data or systems.
From the tool's definition Tool name 'get_source' and description 'Retrieve source object list' indicate data retrieval with no modification, deletion, or execution of external operations.
Attacks that exploit this kind of access
The rule that runs get_source safely
PolicyLayer is an MCP gateway: it sits between your AI agents and OrigeneMCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_source, this is the rule to start with:
get_source is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect OrigeneMCP, apply this rule, and every get_source call is checked against it from then on.
Questions about get_source
Retrieve source object list. It is categorised as a Read tool in the OrigeneMCP MCP Server, which means it retrieves data without modifying state.
Register the Origene MCP server in PolicyLayer and add a rule for get_source: 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 OrigeneMCP. Nothing to install.
get_source 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_source 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_source. 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_source is provided by the Origene MCP server (gentel-lab/origenemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
