Is X402 Bazaar safe and trustworthy?

tashan scores X402 Bazaar on public evidence — tashan score 50.0/100, it is currently active, note: a single primary maintainer (bus-factor risk), no known advisories against the current release. Audit scope: OSV advisories, install-time scripts, build provenance and declared permission surface. We do not review source code or execute the capability.

How do I install X402 Bazaar?

In Claude Code: run `claude mcp add x402-bazaar -- npx -y x402-bazaar-mcp`. In Cursor / Claude Desktop, add it to mcp.json / claude_desktop_config.json.

X402 Bazaar

npm

The Base token-safety toolkit for agents: the only B20 (Base-native token) freeze/seize/rug suite, pre-trade GO/HOLD/STOP gates, honeypot & sellability checks, wallet + approval audits, prices and AI reports — pay per call in USDC over x402, no API keys.

Works with: Claude Code, Cursor, Claude Desktop, Codex CLI, Gemini CLI, Cline, Windsurf, VS Code (installable)
installable: each client documents how to load an MCP server of this type — that is the client's promise, not a claim verified against this capability

Work: Agent development

Who it is for: AI engineer

Install (Claude Code):

claude mcp add x402-bazaar -- npx -y x402-bazaar-mcp

Security audit

Every finding is shown in full — which advisory, the version that fixes it, and the exact command run at install time. Nothing in this audit is behind a licence.

No known advisoriesclearchecked against OSV for 0.2.7 — this package, not its dependency tree

No access inferred from declared dependenciesnothing it depends on reaches files, shell or network. This reads declarations only — built-in APIs are invisible to it, so absence of a declaration is not absence of access

No build provenanceno attestation — the published artifact cannot be traced to its source
