What happened?a bizarre problem emerging, since rc4 update i think. Dont know where it comes form. Making some changes in mcp servers in the lubrechat are not take into account in the api. i tries addding some mcp servers this afternoon but cant see them on the webui. been wandering around for some hours unti i tested to comment all but one mcp servers ... going to the ui all commented are still available except the one i'm trying to add : see the librechat.yaml : ovverride is pointing to the good file : and going insifde the docker itself gives the good file : but when restarting docker it looks like its stalled on an earlier version of the librechat.yaml showing mcp servers disabled but not he one enabled : going to the ui confirm this : 
i suspect it was working nice until rc4 upgrade this morning made many tries even pruning all the containers but no change. i'm stuck never faced such au problem with docker Version Informationghcr.io/danny-avila/librechat-dev latest e32276aa7e86 5 hours ago 1.57GB Steps to Reproduce

Are you using Redis in your setup? You will need to flush the cache when making changes to Here's a quick script you can run: const redis = require('redis');
const dotenv = require('dotenv');
dotenv.config();
async function flushCache() {
const cacheConnection = redis.createClient({
url: process.env.REDIS_URI, // REPLACE WITH REDIS_URI OR USE MAKE ENVIRONMENT AVAILABLE
});
// Connect to Redis
await cacheConnection.connect();
console.log('\nFlushing cache...');
const result = await cacheConnection.flushAll();
console.log('Cache flush result: ' + result);
// Disconnect
cacheConnection.disconnect();
return 'Cache flushed';
}
flushCache()
.then((result) => console.log(result))
.catch(ex => console.log('Error flushing cache:', ex)); |

Actually you don't need to launch any script, your issue is that Redis is caching your old librechat.yaml config. If you intend to use Redis, you need to flush the cache whenever you make changes to your YAML file. Just run docker ps to find your redis container, then: docker exec -it your-redis-container-name redis-cli Do this after editing librechat.yaml but before restarting LibreChat and it should pick up your new MCP servers. |
