Upgrading
Versions before 0.1.3 had a bug where the bundled MCP server bin would exit silently when launched via the npm bin symlink, which is exactly how every MCP client invokes it. If you see no talonic_* tools despite correct config, you are hitting that bug.
The fix: point your args at @latest (or @0.1.3 explicitly) and fully restart the client:
"args": ["-y", "@talonic/mcp@latest"]
