0.1.0-alpha.10 (2026-02-19)

Full Changelog: v0.1.0-alpha.9...v0.1.0-alpha.10

⚠ BREAKING CHANGES

mcp: remove deprecated tool schemes
mcp: Migration: To migrate, simply modify the command used to invoke the MCP server. Currently, the only supported tool scheme is code mode. Now, starting the server with just node /path/to/mcp/server or npx package-name will invoke code tools: changing your command to one of these is likely all you will need to do.

Remote fetch on every HTTP request degrades performance

Medium Severity

newMcpServer() calls getInstructions() which makes a remote HTTP fetch to api.stainless.com on every invocation. In HTTP transport mode, newMcpServer() is called from newServer() on every single POST request. The old newMcpServer was synchronous and cheap. Now every MCP tool invocation in HTTP mode incurs an additional round-trip to a remote API for instructions that are essentially static, adding unnecessary latency to every request.

-    res.status(400).json({
-      jsonrpc: '2.0',
-      error: {


HTTP query options are no longer applied

Medium Severity

newServer now passes the default mcpOptions directly into initMcpServer and no longer parses request query params. Per-request URL options are silently ignored, so HTTP clients cannot override tool settings and invalid query options are never validated.

-    });
-    await server.connect(transport);
+    const transport = new StreamableHTTPServerTransport();
+    await server.connect(transport as any);


HTTP transport session handling regressed

Medium Severity

StreamableHTTPServerTransport is now created without sessionIdGenerator: undefined, but GET/DELETE endpoints still return 405. This can switch the server from stateless behavior to session-based behavior while lacking session lifecycle routes, causing client reconnection/session flows to fail.

+  );


Network error in instruction fetch crashes entire server

High Severity

fetchLatestInstructions gracefully handles HTTP error responses (!response.ok) with a fallback, but if fetch() itself throws (network error, DNS failure, timeout), the exception propagates unhandled. Since getInstructions is called inside newMcpServer during server construction — which in HTTP mode sits outside the try-catch in newServer — a network blip to the Stainless instructions API makes the entire MCP server unable to handle any requests. The old newMcpServer was synchronous and never made network calls, so this is a newly introduced failure path.

Bugbot Autofix prepared fixes for 1 of the 1 bugs found in the latest run.

✅ Fixed: Network error in instruction fetch crashes entire server
- Wrapped the fetch() call in a try-catch block to catch network errors and fall back to default instructions, matching the existing behavior for HTTP-level errors.
