Fact copy: MCP client and capability compatibility
Assessment of protocol versions, transports and optional client capabilities.
Canonical source: https://travel-mcp.com/en/knowledge/practical/client-compatibility/
Factual summary
Assessment of protocol versions, transports and optional client capabilities. The module separates protocol behaviour, travel-domain truth and editorial inference.
Decision question and scope
Assessment of protocol versions, transports and optional client capabilities.
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.
- Protokollversion
- stdio und Streamable HTTP
- Tools, Ressourcen und Prompts
- Sampling, Elicitation und Roots
- Autorisierung und Erweiterungen
Travel case
Ein Server darf Elicitation nicht voraussetzen, wenn der verwendete Travel-Client diese Capability nicht aushandelt; der Prozess benötigt dann einen alternativen Eingabekanal.
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 versionierte Prüfliste hilft, Architekturannahmen gegen konkrete Clients zu testen.
The result must state assumptions, unresolved risks and conditions under which MCP is not the appropriate integration choice.
