The second ai-mcp-proxy binding (added to fix the GET/SSE 502 loop) created a second runtime plugin instance with the same tool config, which ai-mcp-proxy's own duplicate-name detection caught: all three tools (list-customers/get-customer/create-customer) fell back to auto-generated names across both instances. Confirmed via dataplane pod logs right after applying the previous fix. Real fix: one KongRoute for all three MCP HTTP methods (GET/POST/ DELETE) instead of two, one ai-mcp-proxy binding instead of two. ai-mcp-proxy already tolerates multi-method routes (same "skips method selection" notice the existing POST+DELETE route already produces) — extending to GET is the same class of thing, not new risk, and there is now exactly one plugin instance so no duplicate tool names.

# Single route for all three MCP HTTP methods (GET opens the SSE stream,
|
|
# POST carries JSON-RPC, DELETE terminates the session) — deliberately NOT
|
|
# split into two KongRoutes the way catalog-mcp does. ai-mcp-proxy is bound
|
|
# once, to this one route (mcp/pluginbindings.yaml); a second route with
|
|
# its own binding of the *same* KongPlugin creates a second runtime plugin
|
|
# instance with the same tool names, and ai-mcp-proxy's cross-instance
|
|
# duplicate-name detection then falls back to auto-generated tool names
|
|
# for all of them ("Tool custom name 'list-customers' already exists in
|
|
# both plugin X and Y") — found and reverted 2026-08-23, see STATUS.md.
