Fetch specific span recordings by their IDs. Use this tool when you have span IDs from a previous query and need the full details including payloads. This is useful for: - Getting full details for spans found via query_spans - Examining specific requests in detail - Comparing multiple specific spans
AI agents call get_spans_by_ids to retrieve information from Tusk Drift MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and reads span data (HTTP requests, database queries, traces, metrics) from captured application traffic. It has no side effects—it only fetches and displays existing observability information. The tool cannot modify, delete, create, execute commands, or move money.
From the tool's definition 'Fetch specific span recordings by their IDs' and 'Getting full details for spans found via query_spans' and 'Examining specific requests in detail' - all indicate retrieval of previously captured observability data without modification or deletion.
Documented attack patterns abuse exactly the kind of access get_spans_by_ids gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Tusk Drift MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_spans_by_ids:
{
"version": "1",
"default": "deny",
"tools": {
"get_spans_by_ids": {}
}
}get_spans_by_ids is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Fetch specific span recordings by their IDs. Use this tool when you have span IDs from a previous query and need the full details including payloads. This is useful for: - Getting full details for spans found via query_spans - Examining specific requests in detail - Comparing multiple specific spans. It is categorised as a Read tool in the Tusk Drift MCP MCP Server, which means it retrieves data without modifying state.
Register the Tusk Drift MCP server in PolicyLayer and add a rule for get_spans_by_ids: 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 Tusk Drift MCP. Nothing to install.
get_spans_by_ids 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_spans_by_ids 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_spans_by_ids. 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_spans_by_ids is provided by the Tusk Drift MCP server (use-tusk/drift-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Tusk Drift MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
