Returns MyVariant.info build metadata: total indexed variant count, available annotation sources (dbSNP, ClinVar, CADD, dbNSFP, gnomAD), and their current release/build versions.
AI agents call metadata to retrieve information from Mcp Myvariant without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool purely retrieves read-only metadata about the MyVariant.info database, including statistics, source names, and version information. No data is created, modified, deleted, or executed. Blast radius if misused is negligible.

Attacks that exploit this kind of access
Returns MyVariant.info build metadata: total indexed variant count, available annotation sources (dbSNP, ClinVar, CADD, dbNSFP, gnomAD), and their current release/build versions. It is categorised as a Read tool in the Mcp Myvariant MCP Server, which means it retrieves data without modifying state.
Register the Mcp Myvariant MCP server in PolicyLayer and add a rule for metadata: 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 Mcp Myvariant. Nothing to install.
metadata 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 metadata 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 metadata. 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.
metadata is provided by the Mcp Myvariant MCP server (https://gateway.pipeworx.io/myvariant/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Every MCP server has a record like this.
