## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

- **Schema Quality & AI Usability**: 77/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 3160 tokens (~126/item across 25 items; 25 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-09-19 (score 66, +1)

No change was recorded against any check on this day. Stability & Change Management went from 30 to 33. That category is still filling its 30-day observation window: 9 days of observed history at the previous scan, 10 at this one. The score rises as the window fills, whether or not the server changes.

Optionally send your OWN policy (minSmri, denyMintAuthority, maxConcentrationPct…) for an ALLOW/DENY financial firewall, fail-closed.

- `mint` (string, required): Base58 SPL token mint to score.

### `solmachina_simulate` (~107 tokens)

Buy & return: Pre-flight a serialized Solana transaction (simulateTransaction): willSucceed, computeUnits, program logs, err. NEVER signs or sends — a dry-run, not a guarantee. ($0.01 per call, paid over x402 in USDC on Solana mainnet). Requires a funded client wallet (X402_CLIENT_KEY_FILE); otherwise returns an open-gate explainer.

## Common questions

### What is the io.github.imnotamob/solmachina-x402 MCP server?

io.github.imnotamob/solmachina-x402 is an MCP server listed in the public MCP registry as io.github.imnotamob/solmachina-x402. Solana & Base DeFi intelligence for AI agents over x402: decisions, risk, signed receipts. This page covers its npm package (solmachina-x402-mcp).

### Is the io.github.imnotamob/solmachina-x402 MCP server safe to use?

io.github.imnotamob/solmachina-x402 scores 66 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the io.github.imnotamob/solmachina-x402 MCP server expose?

io.github.imnotamob/solmachina-x402 exposes 25 tools: solmachina_catalog, solmachina_status, solmachina_how_to_pay, solmachina_sample, solmachina_verify_receipt, and 20 more. Their descriptions and schemas cost roughly 3,160 tokens of context every time the server is loaded.

### Is the io.github.imnotamob/solmachina-x402 MCP server still maintained?

io.github.imnotamob/solmachina-x402 is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the io.github.imnotamob/solmachina-x402 MCP server under?

io.github.imnotamob/solmachina-x402 declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
