fix(server,catalog): canonicalize tool names at ingress; enforce lowercase in catalog (POLICY-002) - #218
Merged
Conversation
…rcase in catalog (POLICY-002) Tool names are now lowercased in _handle_tool_call() before reaching the proxy, so Cedar policy, catalog, and request always use the same case. Catalog loading now rejects any entry whose tool_name is not already lowercase, preventing inconsistency that could allow a case-variant to bypass deny rules.

Summary
_handle_tool_call()before reaching the proxy, catalog lookup, and Cedar evaluator. This ensures Cedar policy, catalog entries, and client requests all use the same casing. Catalog loading now rejects entries with non-lowercasetool_namewith aConfigError, preventing future inconsistency.Test plan
