Get information about a C. elegans strain including genotype, available from, and associated phenotypes.
AI agents call get_strain to retrieve information from WormBase MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves data about C. elegans strains from the WormBase database. It performs a read-only operation with no side effects, no code execution, no data modification, and no destructive actions. The function retrieves information that already exists in the database for research purposes, consistent with other Read-category tools on this server (get_gene, get_protein, get_phenotype, etc.).
From the tool's definition Tool name 'get_strain' and description indicate retrieval of existing strain information (genotype, availability, phenotypes) with no modification or deletion capability.
Attacks that exploit this kind of access
Get information about a C. elegans strain including genotype, available from, and associated phenotypes. It is categorised as a Read tool in the WormBase MCP Server MCP Server, which means it retrieves data without modifying state.
Register the WormBase MCP Server MCP server in PolicyLayer and add a rule for get_strain: 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 WormBase MCP Server. Nothing to install.
get_strain 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_strain 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_strain. 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_strain is provided by the WormBase MCP Server MCP server (wormbase/wormbase-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
