"textContent": "\n\nWe’re in the process of submitting our MCP to the app directory, and get the error “Tool scan failed: Internal service error”.\n\nTroubleshooting:\n\n 1. The OAuth flow successfully ran.\n 2. Using ngrok we confirmed our service was called & returned a valid 200 response for the tool/list.\n 3. Our full MCP is ~54k tokens, resulting in the 500 error.\n 4. We truncated the tool/list, and found that the tool scan worked when the MCP definition was below ~32k tokens. This worked with any arrangement of tools; the max-size seemed to be the only limitation.\n\n\n\nI’ve submitted a support request to support with specific identifiers. Given the response status is 500, is this a bug?",
