None is a defect that matters on its own; together they are worth one pass.\n\n## 1. Losing the provider race now builds and discards a real Azure exporter\n\n`install_mcp_span_pipeline` was changed to build the exporter and processor before claiming the global provider, which was the right fix for the ordering bug.

It covers every protocol message, it is maintained upstream, and it keeps covering new message types as the protocol evolves without anyone here remembering to add a field. Hand-rolled telemetry is the opposite: every new thing worth measuring is a code chan\n\n[Read the thread](https://github.com/sdebruyn/fabric-dw-mcp-cli/issues/1049) · 2026-08-24 · closed · 0 comments\n\n### security(mcp): non-loopback binds lose Host and Origin validation under SDK v2\n\n## What changes\n\nUnder the MCP SDK v2 migration (#1043 / PR #1045), a server started with a non-loopback host loses Host and Origin validation entirely. The default loopback path is unaffected.\n\nThis is not a change anyone made deliberately. It falls out of where the two SDK versions compute the setting.\n\n**v1**: `FastMCP.__init__` derived `transport_security` from the *constructor's* `host` argument, which this project never passed, so it defaulted to `127.0.0.1` and froze a loopback-only allow\n\n[Read the thread](https://github.com/sdebruyn/fabric-dw-mcp-cli/issues/1046) · 2026-08-24 · closed · 0 comments\n\n### chore(deps)!: migrate to MCP Python SDK v2\n\n## Summary\n\nMigrate from MCP Python SDK 1.28.1 to 2.0.0. This is a real migration, not a version bump: the module tree `mcp.server.fastmcp` does not exist in v2. There is no alias, no shim and no deprecation period, so every module importing it fails at import time. That is why the dependabot PR #1039, which only widens the constraint to `<3`, fails Type check, Unit tests, Runtime smoke and Slow tests at once. #1039 is closed in favour of this.\n\n#1042 has landed (`cacc7b8`).
