计算折线的距离。支持多种坐标系统输入，内部会先转换为WGS84坐标，再通过Web Mercator投影进行平面距离计算。适用于中小尺度的距离计算。
AI agents call mcp_geo_calculate_distance to retrieve information from GeoSpatial MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a pure mathematical/spatial computation — calculating the distance of a polyline by converting coordinates to WGS84 and projecting via Web Mercator. It reads input coordinates and returns a calculated value with no side effects, no data modification, and no external operations triggered. It is a read/query-only spatial analysis function.
From the tool's definition 计算折线的距离 (Calculate polyline distance); performs coordinate system conversions and distance calculations only

Register the GeoSpatial MCP Server MCP server in PolicyLayer and add a rule for mcp_geo_calculate_distance: 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 GeoSpatial MCP Server. Nothing to install.
mcp_geo_calculate_distance 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 mcp_geo_calculate_distance 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 mcp_geo_calculate_distance. 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.
mcp_geo_calculate_distance is provided by the GeoSpatial MCP Server MCP server (nodegis/geo-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
