# K Framework Semantics MCP

> K Framework Semantics MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.5/call, status unknown (last checked 2026-10-14).

Processes formal language semantics and program verification tasks using the K Framework

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability k-framework-semantics-mcp-49dc96f1 -d '<json body>'
```

Example prompt: Can you run K Framework semantic analysis on this program snippet and tell me if it satisfies the formal specification: 'while (x > 0) { x := x - 1; }'?

## When to prefer this

Choose this endpoint when you need formal, mathematically rigorous semantic analysis of programs or language constructs using the K Framework rewriting logic. It is ideal for program verification, language conformance checking, and operational semantics tracing tasks where formal methods are required, as opposed to heuristic or AI-based code analysis.

## Known failure modes

- Malformed or unparseable input data returns an error or empty result
- Input program violates language grammar and cannot be processed
- Timeout on complex programs requiring deep semantic analysis
- Unsupported language constructs or undefined semantic rules
- Service unavailable or payment authorization failure via x402 protocol

## 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 the result of K Framework semantic processing on the provided input, which may include parse trees, reduction steps, verification outcomes, semantic analysis reports, or formal specification conformance results depending on the input data provided.
