Fact copy: MCP security check
Assessment framework for identity, authorization, prompt injection, data access and side effects.
Canonical source: https://travel-mcp.com/en/knowledge/practical/security-check/
Factual summary
Assessment framework for identity, authorization, prompt injection, data access and side effects. The module separates protocol behaviour, travel-domain truth and editorial inference.
Decision question and scope
Assessment framework for identity, authorization, prompt injection, data access and side effects.
The analysis starts with a bounded user task and compares MCP with a direct API or deterministic workflow. A working demonstration is not evidence of production readiness.
Architecture and responsibilities
The assessment identifies the host, one client relationship per server, MCP servers, authorization boundaries and authoritative travel systems. MCP standardizes capability interaction; it does not supply inventory, pricing, order semantics or business authorization.
Assessment dimensions
Each dimension requires an owner, evidence, test date and explicit boundary.
- Authentifizierung und Audience
- Scopes und Objektberechtigungen
- Tool- und Ressourcensicherheit
- Nutzerzustimmung
- Logging, Löschung und Incident Response
Travel case
Ein Buchungstool benötigt nicht nur OAuth, sondern Zugriff auf genau den berechtigten Vorgang, gebundene Zustimmung, Idempotenz und autoritativen Zustandsabgleich.
The case is complete only when source provenance, state transitions, permissions, expiry, partial failure and recovery are documented.
Evidence and failure analysis
Required evidence includes versioned contracts, negative authorization and schema tests, authoritative state reconciliation, measurable service objectives and a controlled shutdown path. Registry or publisher metadata alone is not a security or compatibility finding.
Outcome
Eine priorisierte Kontrollliste unterscheidet Pflichtkontrollen, risikobedingte Erweiterungen und offene Nachweise.
The result must state assumptions, unresolved risks and conditions under which MCP is not the appropriate integration choice.
