Single-target operation
Part of the SmartBear MCP MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call bugsnag_get_span_group to retrieve information from SmartBear MCP without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though bugsnag_get_span_group only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Get detailed performance metrics for a specific span group **Parameters:** - projectId (string): Unique identifier of the project. This is optional if a current project is set and is used to set the current project for BugSnag tools. - spanGroupId (string) *required*: ID of the span group - filters (record<string, array>): Apply filters to narrow down the span group list. Use the List Trace Fields tool to discover available filter fields. Time filters support extended ISO 8601 format (e.g. 2018-05-20T00:00:00Z) or relative format (e.g. 7d, 24h). (default: {"span.since":[{"type":"eq","value":"7d"}]}) **Use Cases:** 1. View detailed statistics (p50, p75, p90, p95, p99) for an operation 2. Check if performance targets are configured 3. Monitor span count to understand operation volume **Examples:** 1. Get details for an API endpoint span group ```json { "spanGroupId": "[HttpClient]GET-api.example.com" } ``` Expected Output: Statistics, category, and performance target info 2. Get span group details with device filtering ```json { "spanGroupId": "[HttpClient]GET-api.example.com", "filters": { "device.browser_name": [ { "type": "eq", "value": "Chrome" } ] } } ``` Expected Output: Statistics filtered for Chrome browser only **Hints:** 1. Use List Span Groups first to discover available span group IDs 2. IDs are automatically URL-encoded - provide the raw ID 3. Statistics include p50, p75, p90, p95, p99 percentiles. It is categorised as a Read tool in the SmartBear MCP MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for bugsnag_get_span_group. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the SmartBear MCP MCP server.
bugsnag_get_span_group 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 bugsnag_get_span_group rule in your Intercept 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 Intercept policy for bugsnag_get_span_group. 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.
bugsnag_get_span_group is provided by the SmartBear MCP MCP server (@smartbear/mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
