Validates the MCP-client loop end-to-end against one real MCP server before the full v1.15 port. New services/mcp-client.ts wraps @modelcontextprotocol/sdk v1.29.0 with Streamable HTTP transport. On startup (when MCP_CONTEXT7_URL is set), connects to Context7, discovers tools via tools/list, wraps each as a ToolDef prefixed context7_<name>, and appends to ALL_TOOLS via appendMcpTools. Read-only invariant guard rejects any tool with readOnlyHint: false. Tool dispatch is transparent — executeToolCall routes MCP calls through the ToolDef execute wrapper, which strips the prefix before calling the MCP server. Result size capped at 5MB with truncation. Graceful degradation: server down at startup → zero tools; server down mid-session → error result, model self-corrects. Adversarial review caught that a Zod .default() on the URL config made MCP always-on instead of opt-in — fixed by removing the default. MCP_CONTEXT7_URL must be explicitly set to enable. ALL_TOOLS changed from ReadonlyArray to mutable to support late-registration. appendMcpTools re-sorts and rebuilds TOOLS_BY_NAME after append. 348/348 server tests passing (16 new mcp-client tests). No schema changes, no frontend changes.
