Unified governance, robust security, optimized multi-model integration for Agentic AIReused

Centralized tool governance

Decide which agents, apps, and users can see or invoke each MCP tool and resource.

Secrets never leak to agents

ForgeCrux injects credentials at the gateway so models and agents never hold raw keys.

One virtual catalog

Compose dozens of MCP servers into a single governed endpoint with consistent identity and audit.

Key Capabilities

MCP server registry for internal, SaaS, and partner servers
Dynamic tool, resource, and prompt discovery
OAuth 2.0, OIDC, API keys, and mTLS for MCP clients
Tool-level RBAC and ABAC authorization
Credential vault with per-tool secret isolation
Virtual MCP servers that compose many backends into one
Tool policies: allow, deny, transform, rate-limit, and approve
Traffic management, retries, and circuit breakers for tools
Audit logging of every list/call/read/subscribe
MCP observability: latency, errors, and usage analytics
Sandboxed execution and egress controls
Stdio, SSE, Streamable HTTP, and remote MCP transports

Complete MCP Gateway capabilities

Everything required to publish, secure, mediate, observe, and operate mcp gateway workloads on ForgeCrux.

Registry, discovery, and virtual servers

Make every MCP server visible, versioned, and composable.

  • Central registry for internal, SaaS, and third-party MCP servers
  • Health checks, versions, and capability advertisements
  • Dynamic discovery of tools, resources, resource templates, and prompts
  • Namespacing and aliases so tools do not collide across servers
  • Virtual MCP servers that fan-in many backends to one client endpoint
  • Allow lists and deny lists of tools per virtual server
  • Schema validation for tool input and output JSON
  • Prompt templates and resource subscriptions through the gateway
  • Stdio, SSE, Streamable HTTP, and WebSocket transports
  • On-prem, VPC, and SaaS server connectivity

Identity, OAuth, and authorization

Authenticate clients and authorize every tool invocation.

  • OAuth 2.0 and OIDC for human and workload clients
  • API keys, mTLS, and SPIFFE/workload identity
  • SSO mapping from enterprise IdP to MCP sessions
  • RBAC and ABAC at server, tool, resource, and parameter level
  • Just-in-time and human-in-the-loop approval for sensitive tools
  • Session binding so a client cannot invoke another tenant’s tools
  • Scoped down tool arguments (path, project, account) by policy
  • Delegation and on-behalf-of tokens for agent chains

Credentials, secrets, and data protection

Keep backend credentials in the vault, not in prompts or agent memory.

  • Encrypted credential vault per server and per tool
  • Automatic token refresh and rotation
  • Secret injection at invocation time
  • Egress allow lists and DLP on tool payloads
  • PII redaction on tool arguments and results
  • Data residency and environment isolation
  • Bring-your-own KMS and HSM-backed keys
  • No raw secrets in traces or logs

Policies, traffic, and safety

Treat tool calls like production API traffic.

  • Allow, deny, transform, and mock policies
  • Rate limits, concurrency limits, and quotas per tool
  • Retries, timeouts, and circuit breakers
  • Argument rewriting and response filtering
  • Dry-run and shadow mode for new tools
  • Sandboxing and network egress control
  • Malicious tool-call and prompt-injection defenses
  • Change windows and break-glass procedures

Observability and analytics

See every list, read, subscribe, and call.

  • Audit log of discovery and invocation with actor and policy
  • Latency, error, and timeout metrics per tool and server
  • Usage analytics by agent, app, team, and tool
  • Distributed traces linking agent → MCP → backend
  • Cost attribution when tools trigger paid APIs
  • Anomaly detection on unusual tool sequences
  • OpenTelemetry export
  • Retention, legal hold, and export for compliance

Platform and developer experience

Ship MCP to production with enterprise operations.

  • MCP-compatible client endpoint for Cursor, Claude, and custom agents
  • SDKs, CLI, and REST APIs to register servers
  • Terraform and Kubernetes operators
  • Environments, revisions, and promotion pipelines
  • Catalog UI for operators and a filtered catalog for agents
  • Contract tests for tool schemas in CI
  • Multi-cloud, on-prem, and air-gapped runtimes
  • High availability and horizontal scale

How teams run MCP Gateway on ForgeCrux

Register servers

Add internal and SaaS MCP servers to the registry, attach credentials, and verify health and advertised tools.

Compose virtual catalogs

Build virtual MCP servers that expose only the tools each team or agent is allowed to see.

Authorize at tool level

Map IdP groups and agent identities to RBAC/ABAC rules down to arguments and resources.

Keep secrets in the vault

Remove keys from agent configs. ForgeCrux injects them on each governed invocation.

Turn on audit

Require traces and audit logs before production agents can call mutating tools.

Operate like APIs

Apply rate limits, SLOs, and promotion workflows so MCP is a production surface, not a side channel.

Related Products

Agent Gateway

ForgeCrux Agent Gateway gives every agent an identity, permissions, routing, memory controls, guardrails, tracing, evaluation, cost limits, and lifecycle—so multi-agent systems can reach models, APIs, MCP tools, and data without unmanaged autonomy.

AI Gateway

ForgeCrux AI Gateway is the single endpoint for multi-model access, intelligent routing, prompt control, guardrails, token and cost management, evaluation, and LLM observability—across OpenAI, Anthropic, Gemini, Bedrock, Azure OpenAI, and self-hosted models.

Control Plane

ForgeCrux One is the enterprise control plane for APIs, AI models, MCP tools, and agents. Platform, security, and SRE teams use it to install, configure, govern, and operate every gateway from one catalog, one policy engine, and one audit trail—across SaaS, hybrid, and air-gapped footprints.
