--- title: Tunnels url: https://platform.claude.com/docs/en/api/java/beta/tunnels --- # Tunnels ## Create Tunnel `BetaTunnel beta().tunnels().create(params = TunnelCreateParams.none(), requestOptions = RequestOptions.none())` **POST** `/v1/tunnels` The Tunnels API is in research preview. It requires the `anthropic-beta: mcp-tunnels-2026-06-22` header and may change without a deprecation period. It supersedes the Admin API endpoints at `/v1/organizations/tunnels`, which remain available during a migration window. Creates a tunnel. Creation allocates a fresh hostname and provisions the tunnel; it is not idempotent. The new tunnel rejects MCP traffic until at least one CA certificate is added. ### Parameters - `TunnelCreateParams params` - `Optional> betas` (header parameter) This endpoint is in beta: requests must send `mcp-tunnels-2026-06-22` in this header. - `MESSAGE_BATCHES_2024_09_24("message-batches-2024-09-24")` - `PROMPT_CACHING_2024_07_31("prompt-caching-2024-07-31")` - `COMPUTER_USE_2024_10_22("computer-use-2024-10-22")` - `COMPUTER_USE_2025_01_24("computer-use-2025-01-24")` - `PDFS_2024_09_25("pdfs-2024-09-25")` - `TOKEN_COUNTING_2024_11_01("token-counting-2024-11-01")` - `TOKEN_EFFICIENT_TOOLS_2025_02_19("token-efficient-tools-2025-02-19")` - `OUTPUT_128K_2025_02_19("output-128k-2025-02-19")` - `FILES_API_2025_04_14("files-api-2025-04-14")` - `MCP_CLIENT_2025_04_04("mcp-client-2025-04-04")` - `MCP_CLIENT_2025_11_20("mcp-client-2025-11-20")` - `DEV_FULL_THINKING_2025_05_14("dev-full-thinking-2025-05-14")` - `INTERLEAVED_THINKING_2025_05_14("interleaved-thinking-2025-05-14")` - `CODE_EXECUTION_2025_05_22("code-execution-2025-05-22")` - `EXTENDED_CACHE_TTL_2025_04_11("extended-cache-ttl-2025-04-11")` - `CONTEXT_1M_2025_08_07("context-1m-2025-08-07")` - `CONTEXT_MANAGEMENT_2025_06_27("context-management-2025-06-27")` - `MODEL_CONTEXT_WINDOW_EXCEEDED_2025_08_26("model-context-window-exceeded-2025-08-26")` - `SKILLS_2025_10_02("skills-2025-10-02")` - `FAST_MODE_2026_02_01("fast-mode-2026-02-01")` - `OUTPUT_300K_2026_03_24("output-300k-2026-03-24")` - `USER_PROFILES_2026_03_24("user-profiles-2026-03-24")` - `USER_PROFILES_2026_08_18("user-profiles-2026-08-18")` - `USER_PROFILES_2026_09_04("user-profiles-2026-09-04")` - `ADVISOR_TOOL_2026_03_01("advisor-tool-2026-03-01")` - `MANAGED_AGENTS_2026_04_01("managed-agents-2026-04-01")` - `CACHE_DIAGNOSIS_2026_04_07("cache-diagnosis-2026-04-07")` - `DREAMING_2026_04_21("dreaming-2026-04-21")` - `THINKING_TOKEN_COUNT_2026_05_13("thinking-token-count-2026-05-13")` - `SERVER_SIDE_FALLBACK_2026_06_01("server-side-fallback-2026-06-01")` - `SERVER_SIDE_FALLBACK_2026_07_01("server-side-fallback-2026-07-01")` - `FALLBACK_CREDIT_2026_06_01("fallback-credit-2026-06-01")` - `FALLBACK_CREDIT_2026_07_01("fallback-credit-2026-07-01")` - `AGENT_MEMORY_2026_07_22("agent-memory-2026-07-22")` - `MID_CONVERSATION_TOOL_CHANGES_2026_07_01("mid-conversation-tool-changes-2026-07-01")` - `COMPACT_2026_01_12("compact-2026-01-12")` - `COMPUTER_USE_2025_11_24("computer-use-2025-11-24")` - `MCP_TUNNELS_2026_06_22("mcp-tunnels-2026-06-22")` - `STRUCTURED_OUTPUTS_2025_11_13("structured-outputs-2025-11-13")` - `TASK_BUDGETS_2026_03_13("task-budgets-2026-03-13")` - `THINKING_DISPLAY_UPDATES_2026_08_18("thinking-display-updates-2026-08-18")` - `CE_USER_MANAGEMENT_2026_07_13("ce-user-management-2026-07-13")` - `MID_CONVERSATION_OUTPUT_CONFIG_2026_07_01("mid-conversation-output-config-2026-07-01")` - `THINKING_BINDING_CONTROLS_2026_08_01("thinking-binding-controls-2026-08-01")` - `MID_CONVERSATION_SYSTEM_CLEAR_AT_2026_08_21("mid-conversation-system-clear-at-2026-08-21")` - `COMPACT_2026_09_04("compact-2026-09-04")` - `INLINE_TOOLS_2026_09_15("inline-tools-2026-09-15")` - `MCP_CLIENT_2026_09_15("mcp-client-2026-09-15")` - `CE_PLUGINS_2026_09_01("ce-plugins-2026-09-01")` - `SPEND_LIMIT_READS_2026_09_26("spend-limit-reads-2026-09-26")` - `TELEMETRY_DESTINATIONS_2026_08_11("telemetry-destinations-2026-08-11")` - `Optional workspaceId` (header parameter) Optional header to select the Workspace for this request.

Archiving the last non-archived certificate is permitted; the tunnel rejects MCP traffic until a new certificate is added. #### Parameters - `CertificateArchiveParams params` - `String tunnelId` (path parameter) ID of the tunnel (`tnl_...`). - `Optional certificateId` (path parameter) ID of the certificate to archive (`tcrt_...`). - `Optional> betas` (header parameter) This endpoint is in beta: requests must send `mcp-tunnels-2026-06-22` in this header. - `MESSAGE_BATCHES_2024_09_24("message-batches-2024-09-24")` - `PROMPT_CACHING_2024_07_31("prompt-caching-2024-07-31")` - `COMPUTER_USE_2024_10_22("computer-use-2024-10-22")` - `COMPUTER_USE_2025_01_24("computer-use-2025-01-24")` - `PDFS_2024_09_25("pdfs-2024-09-25")` - `TOKEN_COUNTING_2024_11_01("token-counting-2024-11-01")` - `TOKEN_EFFICIENT_TOOLS_2025_02_19("token-efficient-tools-2025-02-19")` - `OUTPUT_128K_2025_02_19("output-128k-2025-02-19")` - `FILES_API_2025_04_14("files-api-2025-04-14")` - `MCP_CLIENT_2025_04_04("mcp-client-2025-04-04")` - `MCP_CLIENT_2025_11_20("mcp-client-2025-11-20")` - `DEV_FULL_THINKING_2025_05_14("dev-full-thinking-2025-05-14")` - `INTERLEAVED_THINKING_2025_05_14("interleaved-thinking-2025-05-14")` - `CODE_EXECUTION_2025_05_22("code-execution-2025-05-22")` - `EXTENDED_CACHE_TTL_2025_04_11("extended-cache-ttl-2025-04-11")` - `CONTEXT_1M_2025_08_07("context-1m-2025-08-07")` - `CONTEXT_MANAGEMENT_2025_06_27("context-management-2025-06-27")` - `MODEL_CONTEXT_WINDOW_EXCEEDED_2025_08_26("model-context-window-exceeded-2025-08-26")` - `SKILLS_2025_10_02("skills-2025-10-02")` - `FAST_MODE_2026_02_01("fast-mode-2026-02-01")` - `OUTPUT_300K_2026_03_24("output-300k-2026-03-24")` - `USER_PROFILES_2026_03_24("user-profiles-2026-03-24")` - `USER_PROFILES_2026_08_18("user-profiles-2026-08-18")` - `USER_PROFILES_2026_09_04("user-profiles-2026-09-04")` - `ADVISOR_TOOL_2026_03_01("advisor-tool-2026-03-01")` - `MANAGED_AGENTS_2026_04_01("managed-agents-2026-04-01")` - `CACHE_DIAGNOSIS_2026_04_07("cache-diagnosis-2026-04-07")` - `DREAMING_2026_04_21("dreaming-2026-04-21")` - `THINKING_TOKEN_COUNT_2026_05_13("thinking-token-count-2026-05-13")` - `SERVER_SIDE_FALLBACK_2026_06_01("server-side-fallback-2026-06-01")` - `SERVER_SIDE_FALLBACK_2026_07_01("server-side-fallback-2026-07-01")` - `FALLBACK_CREDIT_2026_06_01("fallback-credit-2026-06-01")` - `FALLBACK_CREDIT_2026_07_01("fallback-credit-2026-07-01")` - `AGENT_MEMORY_2026_07_22("agent-memory-2026-07-22")` - `MID_CONVERSATION_TOOL_CHANGES_2026_07_01("mid-conversation-tool-changes-2026-07-01")` - `COMPACT_2026_01_12("compact-2026-01-12")` - `COMPUTER_USE_2025_11_24("computer-use-2025-11-24")` - `MCP_TUNNELS_2026_06_22("mcp-tunnels-2026-06-22")` - `STRUCTURED_OUTPUTS_2025_11_13("structured-outputs-2025-11-13")` - `TASK_BUDGETS_2026_03_13("task-budgets-2026-03-13")` - `THINKING_DISPLAY_UPDATES_2026_08_18("thinking-display-updates-2026-08-18")` - `CE_USER_MANAGEMENT_2026_07_13("ce-user-management-2026-07-13")` - `MID_CONVERSATION_OUTPUT_CONFIG_2026_07_01("mid-conversation-output-config-2026-07-01")` - `THINKING_BINDING_CONTROLS_2026_08_01("thinking-binding-controls-2026-08-01")` - `MID_CONVERSATION_SYSTEM_CLEAR_AT_2026_08_21("mid-conversation-system-clear-at-2026-08-21")` - `COMPACT_2026_09_04("compact-2026-09-04")` - `INLINE_TOOLS_2026_09_15("inline-tools-2026-09-15")` - `MCP_CLIENT_2026_09_15("mcp-client-2026-09-15")` - `CE_PLUGINS_2026_09_01("ce-plugins-2026-09-01")` - `SPEND_LIMIT_READS_2026_09_26("spend-limit-reads-2026-09-26")` - `TELEMETRY_DESTINATIONS_2026_08_11("telemetry-destinations-2026-08-11")` - `Optional workspaceId` (header parameter) Optional header to select the Workspace for this request.
