Install & config
Client config (built from the install command this repo gives)
{
"mcpServers": {
"shahriar-ahmed-seam-lexcompiler": {
"command": "npx",
"args": ["tsx"]
}
}
}Parsed from the README we fetched on 2026-10-28; we have not executed it.
command/args come from the install command the repository states. When it is ambiguous, the project README wins.
VS Code (.vscode/mcp.json - the key is servers)
{
"servers": {
"shahriar-ahmed-seam-lexcompiler": {
"command": "npx",
"args": ["tsx"]
}
}
}Same server, but VS Code keeps it under <code>servers</code>.
Claude Code (command line)
claude mcp add --transport stdio shahriar-ahmed-seam-lexcompiler -- npx tsx
Claude Code does not read a config file; add the server with this command.

Neuro-Symbolic Law-to-AST Compiler, SMT/Z3 Formal Verifier, and Autonomous Pull Request Enforcer
Domain: JusticeSphere AI / ComplianceOS / GovernanceIQ | Engine: Microsoft Z3 v4.13.4 + OPA Rego + Polyglot AST | Protocol: MCP JSON-RPC 2.0 (2025-03-26)
## Abstract
Enterprise software compliance suffers from a structural impedance mismatch: regulatory statutes and enterprise Data Processing Agreements (DPAs) are authored in natural language, whereas production systems execute as deterministic code and relational schemas. Legal teams interpret regulatory updates in static documents while engineering teams ship hundreds of commits per week across API routes, caching workers, and database schemas.
LexCompiler eliminates the manual translation layer between statutory text and source code. It ingests live regulatory feeds (GDPR, HIPAA, EU AI Act, CCPA/CPRA, EUR-Lex, U.S. Federal Register) and custom enterprise contracts, compiles normative clauses into modal deontic logic predicates, synthesizes machine-verifiable SMT-LIB2 assertions and Open Policy Agent (OPA / Rego) rules, and evaluates them against a repository's live Abstract Syntax Tree (AST) and SQL DDL schemas.
When a statutory clause is amended or a code commit introduces a compliance regression, LexCompiler:
1. Proves the mathematical contradiction (UNSAT) using the Microsoft Z3 Theorem Prover and extracts the minimal Unsat Core and Counterexample Witness Model.
2. Pinpoints the exact offending AST nodes and line ranges across SQL, Python, and TypeScript modules.
3. Synthesizes an AST-preserving code patch via Counterexample-Guided Inductive Synthesis (CEGIS), verifies in an isolated Z3 sandbox that the patched AST transitions from UNSAT to SAT, and commits the remediation branch with an RFC 8032 Ed25519 cryptographic conformity certificate and OASIS SARIF v2.1.0 report.
