[Bug]: Embedded resources on MCP tool responses are discarded

[berabulut]

What happened?

I’m using the GitHub MCP server in LibreChat. get_file_contents tool returns a success message and an embedded resource with a URI (no inline text/blob about the content of the file in the tool result). The reason for this is explained in this comment:
github/github-mcp-server#1383 (comment)

As a result agent can't actually use the file contents from that call.

Version Information

v0.8.8

Steps to Reproduce

1. Connect the GitHub MCP server in LibreChat.
2. Ask an agent to call get_file_contents to read contents of a file in a Github repository.
3. Observe the tool result.

What browsers are you seeing the problem on?

Chrome Version 157

Relevant log output

Ran github_mcp-get_file_contents

· Tool call 2.6sTool call took 2.6 seconds

thanks for the report. LibreChat does pass embedded resource text to the model. GitHub's get_file_contents response includes the file in resource.text, and LibreChat keeps it.

the [Embedded Resource Response: resource] placeholder comes from Bifrost's MCP adapter, which drops the resource body. Updating Bifrost or connecting LibreChat to the GitHub MCP server directly should fix it. can you confirm whether your MCP calls go through Bifrost?

I'm using Bifrost indeed. I will check our MCP config. Thanks!

hey @berabulut, just updating here that Bifrost now supports resources in its 2.4.0 version released around a week ago. it should clear up the above issue and work directly.
