Z3 Theorem Prover MCP
x402
Z3 Theorem Prover MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.5/call, status unknown (last checked 2026-10-16).
Runs Z3 SMT solver theorem proving and satisfiability checking on logical formulas or constraints submitted as data

How this service works
The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.
Output
Returns a JSON object with a transaction hash (txHash) and a boolean success flag indicating whether the Z3 proving job was executed. The actual theorem proving result (satisfiable/unsatisfiable/proof output) is presumably embedded in the response payload alongside the settlement confirmation.
Example use cases
Verify software invariant correctness
“I have a set of constraints from my program: 'a >= 0, b >= 0, a + b <= 100, a - b > 50'. Can you use the Z3 theorem prover to check if these constraints are satisfiable and find a model?”
Check cryptographic protocol consistency
“I need to verify that this logical specification for a handshake protocol is consistent — run it through Z3: 'session_key != null IMPLIES (auth = true AND nonce_used = false)'”
Formal proof of arithmetic property
“Can you prove or disprove using Z3 that for all integers x and y, if x > 2 and y > 2 then x*y > x+y?”

Endpoint
POSThttps://api.m2mcent.com/z3-theorem-prover-mcp/api/process?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cloud-hosted Z3 SMT theorem proving accessible via a paid API call without managing your own Z3 installation. Prefer this for agents that need on-demand formal verification, constraint solving, or satisfiability checking integrated into automated workflows with gasless USDC micro-payments on Base L2.
Side effects
- Malformed or unparseable logical formula in data field returns error
- Overly complex formula may time out or exceed compute limits
- Invalid SMT-LIB syntax causes processing failure
- Payment settlement failure on Base L2 results in rejected request
- Empty or missing data field returns validation error
