​
Migrate developer tools to 1.0

Version 1.0 aligns the product MCP server and CLI with the four-route GA API. Source, package, registry availability, and runtime behavior are separate states; confirm the exact installed version before changing production automation.

​
MCP 0.1 to 1.0

The 1.0 product MCP surface contains exactly verify_email, verify_batch, get_job, and get_results. Pin @bounceless/mcp@1.0.0, restart the MCP client, run initialize, and verify that tools/list returns the four names above. The 0.1 package remains addressable by exact version; no automatic deprecation date is implied.

​
Adopt the CLI

The CLI uses verify, batch submit, batch status, and batch results. batch results --output accepts json or csv and writes to stdout. It does not implement a wait flag. Before moving automation, run npx @bounceless/cli@1.0.0 --help without a key, then test the workflow against controlled fixtures. Store BOUNCELESS_API_KEY in the runtime secret environment and redirect outputs to access-controlled files.
