What mapping_identifiers does on OrigeneMCP
AI agents call mapping_identifiers 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 mapping_identifiers is rated Low
Without a description, confidence is reduced, but the tool name and server context strongly suggest this performs identifier mapping/translation (e.g., converting between gene IDs, accession numbers, or other biomedical identifiers). Such operations are typically read-only lookups with no side effects. The sibling tools are all read operations, supporting this classification.
From the tool's definition Tool name is 'mapping_identifiers' with empty description. The name suggests identifier lookup/translation operations. Context from sibling tools (clinvar_*, depmap_*) indicates this server primarily retrieves biomedical data without modifying it.
Attacks that exploit this kind of access
The rule that runs mapping_identifiers 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 mapping_identifiers, this is the rule to start with:
mapping_identifiers 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 mapping_identifiers call is checked against it from then on.
Questions about mapping_identifiers
mapping_identifiers is a read tool on the Origene MCP server. 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 mapping_identifiers: 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.
mapping_identifiers 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 mapping_identifiers 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 mapping_identifiers. 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.
mapping_identifiers 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.
