Mcp Z3 Prover
Give coding agents direct Z3 SMT solver calls to check constraints, invariants, and logic while you harden critical code paths.
Overview
io.github.daedalus/mcp-z3-prover is a MCP server for the Ship phase that exposes the Z3 SMT solver API to coding agents via stdio.
What is this MCP server?
- MCP wrapper around the Z3 theorem prover API
- PyPI package mcp-z3-prover v0.1.0 with stdio transport
- Lets agents formulate and solve SMT constraints from the IDE
- Useful for parsers, auth rules, scheduling, and config validators
- Server version 0.1.0
- PyPI identifier mcp-z3-prover
What problem does it solve?
Solo builders struggle to manually verify complex boolean and arithmetic constraints hidden in business rules and parsers.
Who is it for?
Developers shipping logic-heavy backends or agents who already think in predicates and want automated satisfiability checks.
Skip if: Builders who only need linting and unit tests without formal methods or SMT experience.
What do I get? / Deliverables
Your agent can invoke Z3 through MCP to prove or refute constraints while you review ship-ready code.
- Agent-accessible Z3 solver tools
- Runnable satisfiability checks on spec snippets
- Faster feedback on logic-heavy ship candidates
Recommended MCP Servers
Journey fit
Shelved under Ship because formal checks and constraint solving support verification before release, not initial feature coding. testing captures proof-oriented validation and property-style reasoning agents can run alongside unit tests.
How it compares
Formal verification MCP bridge, not a generic test runner or Playwright skill.
Common Questions / FAQ
Who is io.github.daedalus/mcp-z3-prover for?
Intermediate and advanced solo builders who use Z3 or SMT ideas and want their coding agent to run solver queries over MCP.
When should I use io.github.daedalus/mcp-z3-prover?
Use it in Ship/testing when validating invariants, authorization matrices, or algorithmic constraints before release.
How do I add io.github.daedalus/mcp-z3-prover to my agent?
Install mcp-z3-prover from PyPI, add the stdio MCP entry to your agent config, and ensure Z3 dependencies match the GitHub repo instructions.
