Direct MCP access expands risk
MCP clients and agents can reach databases, ticketing systems, code repositories, SaaS apps, and internal workflows with fewer controls than normal enterprise apps.
AI agent governance
MCP Gateway for Enterprise AI Agents
Datawiza MCP Gateway sits between agents and MCP servers to validate identity, enforce server, tool, and action policies, protect credentials, and log every decision before tools run.
MCP security
What is an MCP gateway?
An MCP gateway is an inline control point between MCP clients, AI agents, and MCP servers. Instead of letting every agent connect directly to sensitive tools, an enterprise MCP gateway centralizes token validation, authorization, credential handling, approvals, and audit before tool calls run.
Tool permissions need policy
One MCP server may expose read, write, export, and admin-like tools. Access decisions need to happen at the server, tool, action, and user-group level.
Credentials need protection
API keys, OAuth tokens, and local config files are hard to govern once agent experiments spread across teams and desktops.
Built on Agent Gateway
What Datawiza MCP Gateway provides
Datawiza MCP Gateway is a focused solution built on Datawiza Agent Gateway for governing Model Context Protocol traffic. It adds identity-aware policy, credential brokering, approvals, and audit in front of MCP servers.
Centralized MCP control point
Route MCP access through one gateway instead of expecting every MCP server to implement enterprise-grade governance.
Identity-aware MCP access
Validate enterprise IdP tokens and evaluate the user, group, agent, target server, tool, action, and environment.
Tool- and action-level guardrails
Restrict which tools and actions agents can use, apply deny-by-default controls, and constrain high-risk parameters.
Automatic token brokering
Handle token exchange, OAuth token retrieval, and API key injection so agents do not hold downstream credentials.
Guardrails and approvals
Require stronger controls for high-risk MCP actions, strip sensitive data where appropriate, or route actions for human approval.
Audit and visibility
Every MCP access attempt records user identity, agent, server, tool, action, policy, and outcome for export to Sentinel, Splunk, or any SIEM.
Architecture
MCP Gateway Architecture
A secure MCP gateway architecture puts an enforcement layer between agents and MCP servers. Agents authenticate with your enterprise IdP, then send MCP traffic through Datawiza before tool calls reach internal or SaaS MCP servers.
Step 1
Agent or MCP client
Authenticates with Entra ID, Okta, or another IdP and receives a signed access token.
Step 2
Datawiza MCP Gateway
Validates issuer, audience, signature, expiry, scopes, and claims, then checks MCP server, tool, and action policy.
Step 3
MCP servers and tools
Receive only approved MCP requests. Denied, approved, and approval-routed decisions are logged.

Deployment options
Azure / AWS / Google CloudOn-premises / private networkDatawiza-hosted service
Token validation: trust the IdP token only after Datawiza verifies it.
Tool policy: allow or deny by agent, claim, MCP server, tool, action, and environment.
Audit: record who or what called the tool, which policy matched, and the outcome.
MCP Gateway vs API Gateway
MCP Gateway vs API Gateway
Traditional API gateways are useful for API routing, authentication, rate limits, and service protection. MCP gateways solve a different problem: agent-mediated tool access where policy must understand the user, agent, MCP server, tool, action, credential, and business context before a tool runs.
Tool-aware policy
API gateways usually enforce policy at the API endpoint or route level. MCP gateways enforce policy at the server, tool, action, resource, and environment level.
Agent and user context
Agents can chain steps, call tools repeatedly, and act on behalf of users. MCP Gateway evaluates who is asking, which agent is acting, and what the requested tool action can change.
Credential brokering
Instead of leaving OAuth tokens, API keys, and service credentials in agent clients or MCP server configs, Datawiza brokers credentials at the gateway.
Approval-ready actions
Sensitive writes, bulk exports, production changes, and high-risk workflows can be denied, constrained, or routed for approval before the MCP tool executes.
MCP-specific audit
Security teams get an audit record of the user, agent, MCP server, tool, action, policy decision, credential event, and outcome.
Internal MCP
Secure internal MCP servers without rebuilding them
This is the fastest path to value for many enterprises. Put MCP Gateway in front of internal servers to add centralized governance without changing the servers themselves.
Secure internal MCP servers
Keep the MCP server on the internal network behind the gateway and avoid code changes to the server.
Authenticate every request
Authenticate every MCP request with Entra ID, Okta, AWS, or another enterprise identity provider.
Apply policy and log activity
Apply tool-level and action-level access policies and log every request, policy decision, and outcome.
SaaS MCP
Govern SaaS-hosted MCP access without scattering credentials
MCP clients and desktop tools often connect directly to SaaS-hosted MCP servers using locally stored credentials or OAuth tokens. MCP Gateway centralizes how those credentials are handled.
Reduce local credential sprawl
Remove direct token handling from laptops and local config files.
Manage token lifecycle
Centralize token refresh, rotation, revocation, and downstream identity presentation.
Keep one audit trail
Apply policy before a SaaS MCP action is allowed and maintain one unified audit trail.
Evaluation guide
How to Choose an Enterprise MCP Gateway
The best MCP gateway for an enterprise should do more than proxy traffic. It should turn MCP access into an identity-aware, least-privilege, auditable control point that security, platform, and app teams can operate together.
Enterprise IdP integration
Use Entra ID, Okta, Ping, Google Identity, Amazon Cognito, or another OAuth/OIDC IdP as the identity source for MCP access decisions.
Granular authorization
Authorize by user, group, agent, app, MCP server, tool, action, resource, environment, tenant, and risk level.
Credential isolation
Keep downstream OAuth tokens, API keys, service accounts, and legacy credentials out of agent runtimes and local MCP client configuration.
Action guardrails
Apply allow, deny, constrain, approval, rate-limit, and audit controls before an agent can perform sensitive work.
Operational audit
Export MCP decisions, credential events, policy matches, and tool outcomes to the systems your security and compliance teams already use.
Requirements
Best MCP Gateway Requirements for Enterprise AI Agents
A best-fit MCP gateway should support the way enterprises actually adopt AI agents: internal MCP servers, SaaS-hosted MCP servers, developer tools, ERP workflows, data platforms, and custom agents operating across many teams.
Internal MCP server protection
Protect self-hosted MCP servers that expose databases, internal APIs, ERP workflows, code repositories, observability systems, and support tools.
SaaS MCP governance
Govern SaaS MCP access for tools like Salesforce, ServiceNow, Jira, GitHub, Slack, Databricks, Snowflake, and Google Workspace.
Agent and client coverage
Enforce different policies for Claude Desktop, Claude Code, Cursor, Copilot, custom copilots, workflow automations, and service agents.
Sensitive action control
Support read-only, write, export, admin, production, and PII-sensitive actions with different rules and approval requirements.
Room to expand
Extend the same governance model beyond MCP to REST APIs, SaaS connectors, internal services, and future agent-to-agent traffic.
Workflow
How MCP Gateway works
Route MCP traffic through the Datawiza gateway instead of letting agents connect directly to MCP servers.
- 1Route MCP traffic through DatawizaPoint the MCP client or agent workflow at the Datawiza gateway endpoint instead of the direct MCP server URL.
- 2Validate identity and contextValidate the enterprise IdP access token and evaluate the user, group, agent, target MCP server, requested tool, action, and environment.
- 3Enforce tool and action policyAllow, deny, constrain, or route for approval based on centralized policy. Deny by default and allow only what is explicitly permitted.
- 4Broker credentials and log decisionsForward approved MCP requests with the right downstream credential or scope, and record each approved, denied, or approval-routed decision.

FAQ
Frequently Asked Questions
What is an MCP gateway?
An MCP gateway is an inline control point between MCP clients or AI agents and MCP servers. It centralizes identity validation, authorization, credential handling, and audit before agents can invoke tools.
How is MCP Gateway different from direct MCP connectivity?
Direct MCP connectivity lets agents connect to MCP servers one by one, often with local tokens or server-specific permissions. Datawiza MCP Gateway puts one policy and audit layer in front of those connections.
Is MCP Gateway the same as an API gateway?
No. Traditional API gateways focus on API traffic, routes, services, authentication, and rate limits. MCP Gateway is designed for agent-mediated tool access, where policy needs to understand the user, group, agent, MCP server, tool, action, credential, approval requirement, and outcome.
What should enterprises look for in an MCP gateway?
An enterprise MCP gateway should validate identity, enforce least-privilege tool and action policy, broker credentials, support approvals for sensitive actions, and produce audit-ready logs across internal and SaaS-hosted MCP servers.
How does MCP Gateway secure internal MCP servers?
MCP Gateway can protect internal MCP servers by sitting in front of them as the enforcement point. Teams can keep MCP servers on private networks, route MCP traffic through Datawiza, and apply centralized identity, policy, credential, and audit controls without rebuilding every server.
Do we need to change our MCP servers?
No. In common deployments, you route MCP traffic through Datawiza by pointing the MCP client or agent to the gateway endpoint. Datawiza then enforces policy before forwarding approved requests.
How does Datawiza work with Entra ID or Okta for MCP?
Agents can authenticate with Microsoft Entra ID, Okta, Ping, AWS IAM, or another OAuth/OIDC IdP, then present signed access tokens to Datawiza for validation and policy enforcement.
Can Datawiza secure internal and SaaS-hosted MCP servers?
Yes. Datawiza MCP Gateway can sit in front of internal MCP servers that expose enterprise systems and SaaS-hosted MCP servers where credential governance, policy, and audit are important.
