SMT-LIB 2.7 / AIGER / BTOR2 Formal Verification Orchestrator (CDCL + BMC + k-Induction + Craig Interpolation + IC3)

A complete in-browser formal-verification stack — no cvc5/Z3 binary needed: an SMT-LIB 2.7 script parser for the QF_BV + Bool core with Tseitin bit-blasting of the FixedSizeBitVectors operators (add/sub/mul/udiv/urem, shifts, comparators, concat/extract/extend, ite), an AIGER reader (ASCII aag and binary aig with delta decoding; outputs as bad properties), a BTOR2 reader with word-level bit-blasting, and a hand-written CDCL SAT engine (two-watched literals, VSIDS-style activities, 1-UIP learning, restarts) underneath. On sequential models it runs bounded model checking with counterexample-witness traces, k-induction with unique-state strengthening, McMillan-style Craig interpolation computed from the refutation and independently re-certified by SAT before being trusted, and an IC3/PDR-lite frame loop with predecessor-cube blocking.

MCP integration

Add this tool to your Model Context Protocol server so AI agents can list and call it.

Server configuration

Add this block to your MCP client configuration:

List available tools

After connecting to the SSE endpoint, list the exposed tools:

tools/list
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/list"
}

Call this tool

Invoke the tool by its id, passing arguments built from its parameters:

tools/call
{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "smt-smtlib-2-7-cvc5-z3-btor2-aiger-k-induction-cddr-dbg-invariant-synthesis-orchestrator",
    "arguments": {
  "source": "demo-smt-commutativity",
  "modelText": "(set-logic QF_BV) (assert ...) (check-sat)  |  aag M I L O A ...  |  1 sort bitvec 8 ...",
  "engine": "all",
  "depthK": 10
}
  }
}
Chain multiple tools in one session with a comma-separated toolId list, e.g. /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp (max 20).
