Get the environment metadata for a specific run (experiment).
AI agents call swanlab_get_run_metadata to retrieve information from Swanlab without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about an experiment run. It performs no modifications, deletions, code execution, or financial operations. The read-only nature of the SwanLab MCP server and the verb 'Get' in the tool name confirm this is purely a data retrieval operation with no side effects or blast radius if misused.
From the tool's definition Tool description states 'Get the environment metadata for a specific run', which is a retrieval operation with no side effects. The server description confirms 'Enables read-only access to SwanLab workspaces, projects, runs, and metrics'.
Documented attack patterns abuse exactly the kind of access swanlab_get_run_metadata gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Swanlab, and nothing reaches the server without passing your rules. This is the rule we recommend for swanlab_get_run_metadata:
{
"version": "1",
"default": "deny",
"tools": {
"swanlab_get_run_metadata": {}
}
}swanlab_get_run_metadata is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get the environment metadata for a specific run (experiment). It is categorised as a Read tool in the Swanlab MCP Server, which means it retrieves data without modifying state.
Register the Swanlab MCP server in PolicyLayer and add a rule for swanlab_get_run_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 Swanlab. Nothing to install.
swanlab_get_run_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 swanlab_get_run_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 swanlab_get_run_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.
swanlab_get_run_metadata is provided by the Swanlab MCP server (nexisato/swanlab-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Swanlab, 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.
