Security Gateway for AI Tools
Works With Any AI Platform
SolonGate integrates with Claude Desktop, Cursor, Windsurf, VS Code, Cline, and any MCP-compatible client
How the MCP Security Proxy Works
Zero-trust security layer between AI agents and tools — every tool call is intercepted, validated, and logged
Every tool call is validated against policy rules defining granular scope permissions. Block filesystem access outside /logs, restrict database tables, and control API endpoints with declarative rules.
Security Architecture
Five-Step Protection Pipeline
Every AI tool call passes through five security layers before reaching the real server
Schema Validation
Strict JSON schema enforcement rejects malformed or extra fields
- Type checking & field validation
- Rejects unknown properties
- Enforces required fields
Policy Check
Action + scope permissions verified against declared policies
- Role-based access control
- Scope verification
- Permission enforcement
Input Guard
Path traversal, wildcards, and shell characters blocked
- Injection prevention
- Path traversal blocking
- Character sanitization
Tool Execution
Allowed request forwarded to tool server with audit logging
- Secure tool invocation
- Full audit trail
- Error handling
Output Guard
Secrets and PII redacted before returning to agent
- Secret detection & masking
- PII redaction
- Safe response delivery

What SolonGate Protects Against
10 built-in threat detectors covering the most common AI tool attack vectors
Prompt Injection
3-stage hybrid detection: 50 regex patterns, embedding similarity, and DeBERTa ML classifier. Blocks instruction overrides, role hijacking, delimiter injection, and jailbreaks.
Policy Enforcement
Fine-grained allow/deny/condition rules per tool. 12+ condition operators ($contains, $regex, $gt, $in). Version history with instant rollback.
AI Judge
LLM-based secondary review for ambiguous decisions. When rules are uncertain, an AI evaluates the tool call and returns ALLOW or DENY with reasoning.
Path Traversal & SSRF
Blocks ../ traversal, encoded variants, sensitive file access, internal IP targeting, IPv6 bypass, decimal IP obfuscation, and cloud metadata endpoints.
Shell & SQL Injection
Detects command chaining (;, |, &&), subshell wrappers (bash -c), encoded newlines, UNION SELECT, time-based injection, and file operation attacks.
Data Exfiltration
Catches base64 payloads in URLs, DNS exfiltration via long subdomains, webhook service targeting, and curl/wget data piping patterns.
