MCP websocket tools/list locks up

[browsified]

What happened?

When initializing an MCP via websocket and it gets to the tools/list portion, i can see where my service sends back a request like this (stringified)

"{"jsonrpc":"2.0","params":{"tools":[{"name":"confluence","description":"Search Confluence documents and pages","inputSchema":{"properties":{"query":{"description":"Search query string","type":"string"},"space":{"description":"Optional space key","type":"string"}},"required":["query"],"type":"object"}}]},"id":1}"

i then see these logs on librechat side

2025-04-27T23:51:55.202Z info: [MCP][everything] Capabilities: {"logging":{},"prompts":{},"resources":{},"tools":{}}
2025-04-27T23:51:55.762Z debug: [MCP][everything] Transport sending: {"method":"tools/list","jsonrpc":"2.0","id":1}

and then eventually i see this

2025-04-28T00:01:19.572Z info: [MCP] All servers initialized successfully

it locks up for about a min, long enough to timeout, and i cant seem to nail down where its happening. the transports SAYS it is connected
