Glama MCP Gateway
Connect through Glama MCP Gateway for full control over tool access and complete visibility into every call.
Full call logging
Every tool call is logged with complete inputs and outputs, so you can debug issues and audit what your agents are doing.
Tool access control
Enable or disable individual tools per connector, so you decide what your agents can and cannot do.
Managed credentials
Glama handles OAuth flows, token storage, and automatic rotation, so credentials never expire on your clients.
Usage analytics
See which tools your agents call, how often, and when, so you can understand usage patterns and catch anomalies.
Tool Definition Quality
Average 4.3/5 across 3 of 3 tools scored.
Each tool has a clearly distinct purpose with no overlap: get_alerts retrieves alerts by state, get_alert_detail provides details for a specific alert ID, and get_forecast returns weather forecasts by location. The descriptions clearly differentiate their functions, eliminating any potential for misselection.
All tools follow a consistent verb_noun pattern with 'get_' prefix (get_alerts, get_alert_detail, get_forecast). This predictable naming convention makes the tool set easy to understand and navigate without any deviations in style.
Three tools is reasonable for a weather alerts server, covering core functions: listing alerts, getting alert details, and retrieving forecasts. It's slightly minimal but well-scoped; adding tools like historical data or radar might enhance it, but the current count is appropriate for basic operations.
The tool set covers essential weather alert workflows: fetching alerts, accessing details, and obtaining forecasts. Minor gaps exist, such as no tools for historical alerts or broader geographic queries beyond states, but agents can work around these with the provided tools for most common use cases.
