AI agents invoke execute_wcps_query to trigger actions in Rasdaman MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool executes arbitrary queries in WCPS (a declarative language for datacube processing). While the tool description is empty, the name combined with the server's stated purpose—enabling execution of 'complex queries on datacubes'—clearly indicates this performs computation and data retrieval with side effects dependent on the query content.
From the tool's definition Tool name 'execute_wcps_query' indicates execution of WCPS (Web Coverage Processing Service) queries against a rasdaman multidimensional database.
Documented attack patterns abuse exactly the kind of access execute_wcps_query gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Rasdaman MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for execute_wcps_query:
{
"version": "1",
"default": "deny",
"tools": {
"execute_wcps_query": {
"limits": [
{
"counter": "execute_wcps_query_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}execute_wcps_query stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

execute_wcps_query. It is categorised as a Execute tool in the Rasdaman MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Rasdaman MCP Server MCP server in PolicyLayer and add a rule for execute_wcps_query: 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 Rasdaman MCP Server. Nothing to install.
execute_wcps_query is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the execute_wcps_query 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 execute_wcps_query. 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.
execute_wcps_query is provided by the Rasdaman MCP Server MCP server (rasdaman/rasdaman-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Rasdaman MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
