The rule that runs phonetic_search safely
PolicyLayer is an MCP gateway: it sits between your AI agents and GleanMark Trademark Search, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For phonetic_search, this is the rule to start with:
phonetic_search is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect GleanMark Trademark Search, apply this rule, and every phonetic_search call is checked against it from then on.
Questions about phonetic_search
Find trademarks whose WHOLE mark sounds similar to the given mark (Metaphone + trigram, whole-mark similarity threshold). LIMITS: it compares entire marks, so multi-word marks that merely CONTAIN a sound-alike word are invisible to it — "KWIK REWARDS" will NOT surface for a QUICK query even though KWIK sounds like QUICK. Thin or empty results are NEVER evidence that no sound-alike marks exist and NEVER support an availability/clearance conclusion: cross-check with list_marks_containing_term on the likely variant spellings (e.g. KWIK, QUIK, QWIK for QUICK — it enumerates ALL containing marks, including compounds), and answer availability questions with run_knockout_search, the actual clearance engine. It is categorised as a Read tool in the GleanMark Trademark Search MCP Server, which means it retrieves data without modifying state.
phonetic_search accepts 5 parameters: limit, mark_text, include_dead, nice_classes, similarity_threshold. Required: mark_text. The full parameter table on this page comes from the server's own tool schema.
