The Problem: The Agent Risk Gap

Enterprises are rushing to deploy Autonomous AI Agents, but they're hitting a wall of risk. According to Gartner, 74% of enterprises see AI agents as a new attack vector, and over 40% of agentic AI projects will be canceled due to inadequate risk controls.

The current landscape leaves teams with a choice:

  1. Restrict agents to simple, low-value read-only tasks.
  2. Accept the risk of autonomous agents taking destructive, unmonitored actions.

Without a dedicated governance layer, you're flying blind:

  • No visibility: You don't know what your agents are doing until after they do it.
  • No safety rails: There's no way to intercept dangerous operations before they execute.
  • No human-in-the-loop: Sensitive actions happen without manual oversight.
  • No audit trail: When things go wrong, you can't reconstruct the chain of thought.

The Solution: Cordum Agent Control Plane

Cordum is an Agent Control Plane that provides a deterministic governance layer for probabilistic AI minds. It allows you to define, enforce, and audit the behavior of your Autonomous AI Agents across any framework or model.

    subgraph CP [AGENT CONTROL PLANE]
        direction LR
        G[API Gateway] --- S[Scheduler] --- SK[Safety Kernel]
        S --- WE[Workflow Engine]
    end

        A3[Customer Service]
    end
    
    CP -->|Governed Jobs| AGENTS
    AGENTS -->|Audit Trail| CP

Governance Across the Lifecycle

Cordum's Before/During/Across framework provides exhaustive control over your agent operations:

graph LR
    subgraph BEFORE [1. BEFORE - Governance]
        P[Policy Evaluation] --> S[Safety Gating]
        S --> H[Human Approval]
    end
    subgraph DURING [2. DURING - Safety]
        M[Real-time Monitoring] --> C[Circuit Breakers]
        C --> A[Live Approvals]
    end
    subgraph ACROSS [3. ACROSS - Observability]
        F[Fleet Health] --> T[Audit Trail]
        T --> O[Optimization]
    end
    BEFORE --> DURING
    DURING --> ACROSS
  • BEFORE (Governance): Define declarative policies that evaluate job requests before an agent executes. Trigger safety kernel checks, throttle risky actions, or flag operations for human approval.
  • DURING (Safety): Real-time visibility into active agent runs. Monitor progress, handle step-level approvals, and enforce timeouts or circuit breakers on the fly.
  • ACROSS (Observability): Manage your entire fleet from a single control plane. Aggregate audit trails, track capability-based routing, and observe agent pool health in real-time.

Quickstart

First Time?

| Goal | Path | |------|------| | Just want to try it? | ./tools/scripts/quickstart.sh (below) | | Manual step-by-step? | docs/quickstart.md | | Developing Cordum? | CONTRIBUTING.md |

Prerequisites

  • Docker Desktop v4+ or Docker CLI v20.10+ with Compose v2 (4GB+ RAM allocated)
  • jq (recommended, for parsing API responses)
  • Go 1.24+ (optional, only needed for cordumctl or cert generation)
git clone https://github.com/cordum-io/cordum.git
cd cordum
./tools/scripts/quickstart.sh

That's it. The script auto-creates .env, generates API keys and Redis password, builds all services, and runs health checks. No manual configuration needed.

Dashboard: http://localhost:8082 Login: admin / admin123 (change in .envCORDUM_ADMIN_PASSWORD)

cp .env.example .env
# Edit .env: set CORDUM_API_KEY (or generate: openssl rand -hex 32)
export CORDUM_API_KEY="your-key-here"
go run ./cmd/cordumctl up
open http://localhost:8082

Deploy to Kubernetes

helm install cordum oci://ghcr.io/cordum-io/cordum/charts/cordum \
  --namespace cordum --create-namespace \
  --set secrets.apiKey=$(openssl rand -hex 32) \
  --set redis.auth.password=$(openssl rand -hex 32) \
  --set ingress.enabled=true \
  --set ingress.className=nginx \
  --set ingress.api.host=api.cordum.example.com \
  --set ingress.dashboard.host=cordum.example.com

See cordum-helm/ for the full Helm chart reference. Chart also available on Artifact Hub.

Ports

| Port | Service | |------|---------| | 8082 | Dashboard | | 8081 | API Gateway (HTTPS) | | 9080 | gRPC Gateway | | 4222 | NATS | | 6379 | Redis | | 9092 | Gateway Metrics | | 9093 | Workflow Engine Health | | 50051 | Safety Kernel (gRPC) | | 50400 | Context Engine (gRPC) |

Port conflicts? If any port is already in use, either stop the conflicting service or override ports in your .env file before starting the stack.

After Setup

# Submit a test job
curl -sS --cacert ./certs/ca/ca.crt \
  -X POST https://localhost:8081/api/v1/jobs \
  -H "X-API-Key: $CORDUM_API_KEY" -H "X-Tenant-ID: default" \
  -H "Content-Type: application/json" \
  -d '{"topic":"job.default","context":{"prompt":"hello"}}'

# Stop the stack
docker compose down

# View logs
docker compose logs -f api-gateway

Troubleshooting

| Issue | Fix | |-------|-----| | Port already in use | docker compose down then retry, or check lsof -i :8082 | | Docker out of memory | Allocate at least 4 GB RAM to Docker Desktop | | Can't login to dashboard | Default credentials: admin / admin123 | | TLS/SSL cert errors | Remove ./certs/ and re-run — certs auto-regenerate | | openssl not found | Not needed — quickstart.sh auto-generates keys without it | | Go build fails | Requires Go 1.24+ — check with go version | | Stale config after changes | redis-cli DEL cfg:system:default then restart |

Key Features

| Governance Feature | Why It Matters for Enterprise | |--------------------|--------------------------------| | Safety Gating | Prevents agents from executing destructive or unauthorized actions before they occur. | | Output Quarantine | Automatically blocks PII leaks, secrets, or hallucinated results from reaching the client. | | Human-in-the-Loop | Mandates human oversight for high-risk operations (e.g., financial transfers, prod access). | | Pool Segmentation | Ensures sensitive data only reaches agents in trusted environments. | | Deterministic Audit | Prove exactly why a decision was made with a full chain-of-thought audit trail. | | Governance Policies | Declarative YAML-based rules that map enterprise risk to agent behavior. | | Policy Simulator | Test your governance rules against historical data before rolling them out to production. |

Protocol: CAP — The Open Standard for Agent Governance

Cordum implements CAP (Cordum Agent Protocol), an open protocol specifically designed for distributed AI agent governance. CAP provides a unified interface for defining agent capabilities, submitting jobs, and enforcing safety policies across heterogeneous agent pools.

CAP vs. MCP: Why You Need Both

While both are essential, they solve different parts of the agent stack:

| Protocol | Focus | Level | Responsibility | |----------|-------|-------|----------------| | MCP (Model Context Protocol) | Tool Calling | Local | How a model interacts with a tool. | | CAP (Cordum Agent Protocol) | Governance | Network | How an agent is governed within an enterprise. |

  • MCP is for within the agent — it defines how a model calls local tools.
  • CAP is for above the agent — it defines the governance control plane for the entire agent fleet.

Use CAP for high-level orchestration and safety gating, and MCP inside your agents for fine-grained tool integration.

Read the full deep dive: MCP vs CAP: Why Your AI Agents Need Both Protocols

MCP Server

Cordum includes an MCP server framework with:

  • Standalone stdio mode via cmd/cordum-mcp (for Claude Desktop/Code local integration)
  • Gateway HTTP/SSE mode via /mcp/message and /mcp/sse (when mcp.enabled=true)

See docs/mcp-server.md for setup, auth headers, and client configuration examples.

SDK

The Go SDK makes it easy to build CAP-compatible workers:

import (
    "log"

    "github.com/cordum/cordum/sdk/runtime"
)

type Input struct {
    Prompt string `json:"prompt"`
}

type Output struct {
    Summary string `json:"summary"`
}

func main() {
    agent := &runtime.Agent{Retries: 2}

    runtime.Register(agent, "job.summarize", func(ctx runtime.Context, input Input) (Output, error) {
        // Your agent logic here
        return Output{Summary: input.Prompt}, nil
    })

    if err := agent.Start(); err != nil {
        log.Fatal(err)
    }
    select {}
}

SDKs: Go (stable) | Python | Node
