Reclassify raster values using a mapping dictionary. Args: raster_path: Path to the input raster. reclass_map: Dictionary mapping old values to new values (e.g., {1: 10, 2: 20}). output_path: Path to save the reclassified raster. Returns: Dictionary with status and message.
AI agents use reclassify_raster to create or update resources in GIS MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GIS MCP Server environment.
reclassify_raster performs a data transformation and writes the result to a new file, which is a Write-category operation. It modifies geospatial data but does so reversibly by creating a new output file rather than destructively altering the source.
From the tool's definition Tool creates a new raster file at output_path with transformed data (reclassified values). The description states it saves to an output_path, indicating file creation/modification.
Documented attack patterns abuse exactly the kind of access reclassify_raster gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and GIS MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for reclassify_raster:
{
"version": "1",
"default": "deny",
"tools": {
"reclassify_raster": {
"limits": [
{
"counter": "reclassify_raster_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}reclassify_raster stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Reclassify raster values using a mapping dictionary. Args: raster_path: Path to the input raster. reclass_map: Dictionary mapping old values to new values (e.g., {1: 10, 2: 20}). output_path: Path to save the reclassified raster. Returns: Dictionary with status and message. It is categorised as a Write tool in the GIS MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the GIS MCP Server MCP server in PolicyLayer and add a rule for reclassify_raster: 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 GIS MCP Server. Nothing to install.
reclassify_raster is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the reclassify_raster 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 reclassify_raster. 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.
reclassify_raster is provided by the GIS MCP Server MCP server (mahdin75/gis-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from GIS MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
