Alternatives to X402 Notary Mcp

Dead code detection, security scanning, and code quality analysis for Python, TypeScript, and Go. 98% recall with fewer false positives than Vulture. Includes AI-powered remediation.

Real-time security framework for MCP servers that detects and blocks malicious AI agent behavior by analyzing tool call patterns and intent across multiple threat detection engines.

Emilia Protocol

Human sign-off + trust receipts for AI agents: requires a named human's approval before an irreversible action (payment release, record change, deploy), then mints an offline-verifiable Ed25519 Trust Receipt. Also exposes trust profiles, receipt verification, disputes, and delegation. Apache-2.0; policy engine formally verified. Install: npx -y @emilia-protocol/mcp-server.

Runtime governance for MCP tool calls. Blocks prompt injection and capability abuse before tool results reach your agent.

Taskbounty Check

Local-only GitHub Actions and CI maintenance scanner for AI-built apps. Exposes scanrepo, explainfinding, and generatefixplan to MCP clients; reads only allowlisted workflow and update configuration, modifies nothing, makes no outbound requests by default, and has zero runtime dependencies. Run with npx -y taskbounty-check@0.1.6 mcp.

URL intelligence for AI agents. 13 tools for security signals and data quality: redirect behaviour, brand impersonation detection, domain age, SSL validation, parked detection, URL structural analysis, DNS enrichment.

URL fetcher and HTML-to-markdown converter with three-layer prompt injection defense: pre-extraction sanitization of hidden/off-screen elements and non-printing Unicode, 15-pattern risk scanning (HIGH/MEDIUM/OK), and per-request session-salt content boundary wrapping.

MCP server for integrating Ghidra with AI assistants. This plugin enables binary analysis, providing tools for function inspection, decompilation, memory exploration, and import/export analysis via the Model Context Protocol.

Headless IDA Pro binary analysis via MCP. Multi-session concurrency with Go orchestration and Python workers. Supports Il2CppDumper and Blutter metadata import for Unity and Flutter reverse engineering.

Embeds Snyk's security engines into agentic workflows. Secures AI-generated code in real-time and accelerates the fixing vulnerability backlogs.

Proof-of-behavior enforcement for AI agents. Define behavioral covenant rules (permit/forbid/require), enforce at runtime before execution, get SHA-256 hash-chained tamper-evident audit logs, and verify compliance independently. Cross-agent verification handshake — no proof, no transaction. MIT licensed, 4,244 tests.

Access the OSV (Open Source Vulnerabilities) database for vulnerability information. Query vulnerabilities by package version or commit, batch query multiple packages, and get detailed vulnerability information by ID.
