Formal Logic
Formal Logic MCP is a Model Context Protocol server that provides deterministic reasoning capabilities without any LLM dependencies. It offers: * **Propositional Logic**: SAT solving, CNF conversion, consistency checking, and entailment. * **First-Order Logic**: Theorem proving using the Z3 SMT solver. * **Temporal Logic**: Trace-based LTL model checking. * **100% Deterministic**: Identical input always produces identical output — fully cacheable and auditable. * **High Performance**: Fast execution taking under 5 seconds for typical queries. Ideal for API contract verification, state machine validation, detecting contradictions in business rules, and system requirements analysis.

The Claude Discoverability Score will be the percentage of contested conversations where Formal Logic appears in the connector picker or Claude invokes it directly. Found and Positioned will be shown as diagnostics, not score inputs.
Community connectors appear on this scale after Claude verifies them and they become eligible for organic discovery.
FoundDiagnostic
Whether Claude found your Connector in connector search. It must be Found before it can reach the picker, but the score counts picker appearances—not search results.
PickedMain score
How often your Connector appeared in the picker, or Claude invoked it directly, across contested conversations. This percentage is the Discoverability Score; the headline number is rounded.
PositionedDiagnostic
What position your Connector appeared in when it was shown in the picker. This shows prominence, but it does not affect the score.
