Connect AI agents to real enterprise systems without turning every tool into an uncontrolled security boundary. Agent-to-tool interactions are part of your enterprise security architecture.
MCP clients, servers, and gateways need more than connectivity. Design token validation, audience restrictions, least-privilege scopes, tool inventories, secrets handling, and risk-based approval requirements together.
Bind tool requests to verified user and workload identities. Carry the correct user context and validate identity at each trust boundary.
Development Agentverifiedrepository.searchread-onlyfictional-repositorylowdecision recordedVerified identity and read-only permissions match the requested repository. Access is permitted and the audit event is recorded.
All operations use fictional data. No enterprise systems are connected, no credentials are collected, and no tool commands or deployments are executed.
Fictional boundary examples illustrate risks and practical safeguards. No single control eliminates every prompt injection or agent security risk.
Untrusted content attempts to influence an agent’s instructions or behavior.
A retrieved document introduces instructions across a data-to-agent boundary.
Separate data from instructions, constrain tool access, and require review for sensitive actions.
Observe unexpected tool requests and changes in workflow intent.
An untrusted or modified tool description misrepresents its capabilities or behavior.
A changed description crosses the server-to-tool-inventory boundary.
Review tool provenance, allowlist servers, and monitor metadata changes.
Record tool inventory revisions and flag unexpected capability changes.
An agent or tool receives broader access than its task requires.
A read-only task receives a token with write permissions.
Scope permissions to specific operations and resources. Use short-lived, audience-restricted tokens.
Compare requested operations with approved scopes and actual usage.
A trusted component uses its privileges on behalf of an unauthorized party.
An agent request crosses into a privileged gateway without caller context.
Validate the caller and resource authorization; preserve user context across boundaries.
Trace requester identity, token audience, and delegated action decisions.
Secrets or access tokens are mishandled across system boundaries.
A tool response includes a credential in an agent-visible output.
Isolate secrets, redact sensitive outputs, and avoid embedding credentials in prompts.
Monitor secret-handling paths and audit token use without logging token values.
Sensitive information leaves an approved trust boundary.
A restricted retrieval result is directed toward an unapproved external destination.
Classify data, enforce retrieval access and egress policies, and review sensitive transfers.
Correlate resource access, destinations, and anomalous transfer patterns.
Cooperating agents introduce additional authorization and accountability challenges.
One agent forwards a task to a second agent with different privileges.
Authenticate each agent, define delegation limits, and keep independent authorization checks.
Maintain correlated traces across agent identities and delegation events.
A tool performs a high-impact action without appropriate approval.
An infrastructure request reaches deployment without a human checkpoint.
Sandbox execution, constrain resource use, and require approvals for high-risk operations.
Record approval state and correlate tool execution with policy decisions.
Structure security outcomes, governance, and risk management.
