Correctover MCP Server

Correctover - MCP Runtime Security & Agent Fault Diagnosis

We are the runtime security layer for the MCP ecosystem.

Correctover is the first MCP server purpose-built for agent fault diagnosis & self-healing. It monitors tool calls across your LLM providers, detects failures in real-time, and auto-repairs them using a knowledge base of 215 fault patterns and 19 CVEs — all at 22μs P50 latency.

What It Does

Pricing

Free forever for individual developers. Scale when you need to.

Pay-per-use: $0.05/call after free tier. No commit, cancel anytime.

Quick Start

Cursor / Claude Desktop / Windsurf

Add to your MCP config:

{
  "mcpServers": {
    "correctover": {
      "command": "npx",
      "args": ["-y", "correctover-mcp-server"],
      "env": {
        "ANTHROPIC_API_KEY": "your-key-here"
      }
    }
  }
}

MCP Tools

Once connected, you get 3 tools:

• diagnose_error — Paste an error, get root cause + fix suggestion in seconds
• get_fault_pattern — Look up a specific fault pattern by ID or keyword
• get_repair_suggestion — Get step-by-step repair instructions for a detected fault

Why Correctover?

The Problem

MCP agents fail constantly. Tool call timeouts, auth errors, schema mismatches, provider outages, rate limits — the list goes on. Developers waste hours debugging errors that have known solutions.

Our Solution

We've built the largest empirical MCP fault database: 150,000+ real-world failure cases across 32 MCP frameworks, categorized into 215 distinct fault patterns with 97.4% automatic self-heal rate.

When your agent hits an error, Correctover:

1. Detects the fault pattern in 22μs (P50)
2. Classifies it against our 215-pattern knowledge base
3. Repairs it automatically (or suggests a fix)
4. Fails over to a healthy provider if needed

The Numbers

• 215 fault patterns cataloged
• 19 CVEs documented
• 150K+ empirical data points
• 97.4% automatic self-heal rate
• 22μs P50 detection latency
• 32 frameworks analyzed
• 5,100+ monthly downloads (PyPI + npm)

CCS: The Open Standard

Correctover is the reference implementation of CCS (Runtime Security Conformance Standard for MCP) — a vendor-neutral open standard for MCP runtime security.

• Standard: Open for community contribution
• Goal: Make MCP safe by default, across all frameworks

Framework Integration

We actively contribute security research to the MCP ecosystem:

Security Research

Our fault database powers active security research:

• GHSAs: 4 published (1 Accepted, 3 draft)
• Fault Taxonomy: 215 patterns + 19 CVEs across 32 frameworks
• Bug Bounty: Active submissions to huntr, HackerOne, MSRC
