WHAT IT DOES

What bench_echo does on ChukMCPServer

AI agents call bench_echo as a supporting operation in ChukMCPServer workflows.

RISK

Why bench_echo is rated Low

The description is empty, lowering confidence significantly. The 'bench_' prefix seen in sibling tool 'bench_add' suggests a benchmarking variant, and 'echo' typically reflects input without side effects, suggesting a Read/Other classification. Since it likely just returns input for performance testing purposes, Other or Read is most appropriate, but with low confidence due to missing description.

From the tool's definition Tool name is 'bench_echo' and description is empty. Based on sibling tool 'echo' and the 'bench_' prefix (suggesting benchmarking), this likely reads/reflects input back.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs bench_echo safely

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

bench_echo Rate-limited

bench_echo gets a rate cap, and everything else on the server is denied unless you say otherwise.

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