Lengthy mcp.tool.result.content causes Sentry to drop critical MCP fields during serialization #105528
Description
Environment
SaaS (https://sentry.io/)
Steps to Reproduce
When tool results are large (>5k chars), Sentry appears to drop essential MCP fields needed for the MCP Insights dashboard, preventing tools from appearing in the "Most Used Tools" graph.
Expected Result
Tools dashboard is populated without truncating fields. If this is a payload size limit, this should be documented.
Actual Result
Tools dashboard is not populated in MCP. However, truncating mcp.tool.result.content leads to expected result.
