From 570b51d07bb0614838c991731caa954fc5c8dff7 Mon Sep 17 00:00:00 2001 From: stranger2904 Date: Wed, 14 Jan 2026 00:39:31 -0500 Subject: [PATCH 01/10] feat(skill-mcp): add HTTP transport support for remote MCP servers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add support for connecting to remote MCP servers via HTTP in addition to the existing stdio (local process) connections. This enables skills to use cloud-hosted MCP servers and aggregated MCP gateways. ## Changes - Extend SkillMcpManager to detect connection type from config: - Explicit `type: "http"` or `type: "sse"` → HTTP connection - Explicit `type: "stdio"` → stdio connection - Infer from `url` field → HTTP connection - Infer from `command` field → stdio connection - Add StreamableHTTPClientTransport from MCP SDK for HTTP connections - Supports custom headers for authentication (e.g., API keys) - Proper error handling with helpful hints - Maintain full backward compatibility with existing stdio configurations ## Usage ```yaml # HTTP connection (new) mcp: remote-server: url: https://mcp.example.com/mcp headers: Authorization: Bearer ${API_KEY} # stdio connection (existing, unchanged) mcp: local-server: command: npx args: [-y, @some/mcp-server] ``` ## Tests Added comprehensive tests for: - Connection type detection (explicit type vs inferred) - HTTP URL validation and error messages - Headers configuration - Backward compatibility with stdio configs --- .../skill-mcp-manager/manager.test.ts | 328 ++++++++++++++++-- src/features/skill-mcp-manager/manager.ts | 178 +++++++++- 2 files changed, 472 insertions(+), 34 deletions(-) diff --git a/src/features/skill-mcp-manager/manager.test.ts b/src/features/skill-mcp-manager/manager.test.ts index 2313e22ee5..4f43247a23 100644 --- a/src/features/skill-mcp-manager/manager.test.ts +++ b/src/features/skill-mcp-manager/manager.test.ts @@ -15,34 +15,272 @@ describe("SkillMcpManager", () => { }) describe("getOrCreateClient", () => { -

This addresses reviewer feedback about test reliability: - Tests are now faster (no network latency) - Tests are deterministic across environments - Test intent is clearer (unit testing error handling logic) The mock throws immediately with a controlled error message, allowing tests to validate error handling without network dependencies.
