Correctover - MCP Runtime Security & Agent Fault Diagnosis

Name: mcp server
Author: correctover

We are the runtime security layer for the MCP ecosystem. Featured in awesome-mcp-servers — the definitive MCP server directory.

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

Capability	Description
🔍 Fault Diagnosis	Instantly diagnose why your agent's tool call failed — timeout, auth, schema, rate limit, provider down
🔧 Auto Self-Healing	97.4% of detected faults are automatically repaired with zero human intervention
🔄 Multi-Provider Failover	Seamlessly failover across 9+ LLM providers when one goes down
📊 Fault Pattern Matching	Match errors against 215 known fault patterns from 150K+ empirical data points
🔒 Runtime Security	Intercept RCE, SSRF, and cloud credential hijacking attempts at the MCP layer
🔑 BYOK	Bring Your Own Key — works with Anthropic, OpenAI, Mistral, Google, Cohere and more

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:

Detects the fault pattern in 22μs (P50)
Classifies it against our 215-pattern knowledge base
Repairs it automatically (or suggests a fix)
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.
