WHAT IT DOES

What gribstream_resolve_shared_parameter does on GribStream MCP

AI agents call gribstream_resolve_shared_parameter to retrieve information from GribStream MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`alias`	string	—	Optional output alias for the resolved request.
`dataset`	string	—	Optional dataset code to resolve the shared parameter against.
`parameter`	string	Yes	Shared parameter code, for example temperature_2m, wind_speed_10m, mean_sea_level_pressure, or wind_speed_500hpa.

Parameters from the server's own tool schema.

RISK

Why gribstream_resolve_shared_parameter is rated Low

The tool purely resolves and returns metadata about a shared parameter preset (variables and expressions). It performs no writes, executions, or data retrieval of actual weather values. Explicitly described as read-only with no side effects.

From the tool's definition NO AUTH / PUBLIC / READ-ONLY. Resolves one shared parameter preset for a dataset, returning native variables and expressions... This tool does not execute the request, query weather values, or return forecast data.

RECOMMENDED RULE

The rule that runs gribstream_resolve_shared_parameter safely

PolicyLayer is an MCP gateway: it sits between your AI agents and GribStream MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For gribstream_resolve_shared_parameter, this is the rule to start with:

gribstream_resolve_shared_parameter Allowed

gribstream_resolve_shared_parameter is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect GribStream MCP, apply this rule, and every gribstream_resolve_shared_parameter call is checked against it from then on.

Questions about gribstream_resolve_shared_parameter

What does the gribstream_resolve_shared_parameter tool do? +

NO AUTH / PUBLIC / READ-ONLY. Resolves one shared parameter preset for a dataset, returning native variables and expressions to use in /timeseries or /runs request bodies. This tool does not execute the request, query weather values, or return forecast data. It is categorised as a Read tool in the GribStream MCP MCP Server, which means it retrieves data without modifying state.

What parameters does gribstream_resolve_shared_parameter accept? +

gribstream_resolve_shared_parameter accepts 3 parameters: alias, dataset, parameter. Required: parameter. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on gribstream_resolve_shared_parameter? +

Register the GribStream MCP server in PolicyLayer and add a rule for gribstream_resolve_shared_parameter: 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 GribStream MCP. Nothing to install.

What risk level is gribstream_resolve_shared_parameter? +

gribstream_resolve_shared_parameter is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit gribstream_resolve_shared_parameter? +

How do I block gribstream_resolve_shared_parameter completely? +

Set action: deny in the PolicyLayer policy for gribstream_resolve_shared_parameter. 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.

What MCP server provides gribstream_resolve_shared_parameter? +

gribstream_resolve_shared_parameter is provided by the GribStream MCP server (https://gribstream.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
