MCP Security • Tool Call Monitoring • Permission Policies

Secure Your AI Agents
Build Safely, Deploy Confidently

The AI Security Layer for autonomous agents: Monitor every tool call, enforce granular permissions, detect prompt injection, and maintain complete audit trails. Part of our unified platform with API security, AI gateway, and verification engine.

AI Agent Threats We Prevent

Autonomous agents face unique security challenges. G8KEPR protects against all of them.

Prompt Injection

Attackers manipulate agent prompts to bypass restrictions and execute unauthorized actions. We detect injection patterns and block malicious prompts in real-time.

Prevention: Pattern detection, input sanitization, prompt validation

Unauthorized Tool Calls

Agents attempt to call tools or resources they shouldn't access. We enforce granular permission policies and block unauthorized calls before execution.

Prevention: Permission policies, role-based access, call-level authorization

Data Leakage

Sensitive data from tool responses gets exposed or logged inappropriately. We redact PII, enforce data classification, and maintain secure audit trails.

Prevention: PII redaction, data classification, secure logging

Four Platforms for AI Agent Security

API Security + MCP Security + AI Gateway + Verification Engine — unified protection for autonomous agents

MCP Security

Primary for AI Agents

Every MCP tool call passes through G8KEPR's security layer. Validate permissions, check arguments, detect anomalies, and log everything before execution.

  • Real-time permission validation
  • Argument type checking and sanitization
  • Anomaly detection (unusual patterns)
  • Complete audit trail for compliance

API Security

Agent Endpoints

Protect the APIs your agents call. Rate limiting, JWT auth, threat detection, and WAF protection for all external API interactions.

  • Agent-specific rate limiting
  • JWT auth per agent identity
  • 30+ threat detection patterns
  • Request/response validation

AI Gateway

LLM Routing

Route your agent's LLM calls through multiple providers. Automatic failover, cost tracking, and provider-agnostic integration.

  • Claude, GPT-4, Gemini routing
  • Automatic failover (99.9% uptime)
  • Per-agent cost tracking
  • Prompt caching & optimization

Verification

Agent Plugins

Access pre-built security plugins for common agent patterns. Prompt validators, tool whitelists, and compliance rules ready to deploy.

  • Prompt injection detectors
  • Tool whitelist templates
  • Compliance policy packs
  • Custom plugin development

Granular Permission Policies

Define exactly what each agent can and cannot do. Create policies per agent, per tool, or per environment. Enforce least-privilege access automatically.

  • Role-Based Access Control

    Assign roles to agents with predefined permission sets

  • Per-Tool Permissions

    Control exactly which tools each agent can access

  • Environment Isolation

    Different policies for dev, staging, and production

  • Policy Version Control

    Track changes, rollback policies, maintain audit history

Simple Integration

Add MCP security to your AI agents in minutes

Python
Works with all MCP servers
from g8kepr import G8KEPR
from mcp import MCPServer

# Wrap your MCP server with G8KEPR security
server = MCPServer(tools=[read_file, write_file, api_request])
secure_server = G8KEPR(
    server,
    api_key="your-api-key",
    policies="agents/research-assistant.json"
)

# All tool calls are now secured automatically
# - Permissions validated before execution
# - Arguments sanitized and type-checked
# - Full audit trail maintained
secure_server.start()

AI Agent Use Cases

Secure any type of autonomous agent

Code Assistants

Secure agents that read/write files, execute code, and interact with git. Prevent unauthorized file access and code execution.

Tools secured: read_file, write_file, execute, git

Research Agents

Protect agents that search the web, query databases, and aggregate data. Control which sources they can access.

Tools secured: web_search, sql_query, api_request

Customer Support Bots

Secure agents that access CRM, send emails, and process refunds. Prevent unauthorized customer data access.

Tools secured: crm_lookup, send_email, process_refund
