Odd Session Blocking MCP Bug #3298
Description
Description
After adding the RepoPrompt MCP to my config file sessions just hang at launch with no errors in the logs even with debug mode enabled.
Below is the config used based on RepoPrompt's install instructions.
"RepoPrompt": {
"type": "local",
"command": ["/Users/simon/RepoPrompt/repoprompt_cli"],
"enabled": true
}
The RepoPrompt team thought that maybe it was waiting for an attribute even though the command doesn't need one. So I added a fake attribute and that seemed to get things working.
"RepoPrompt": {
"type": "local",
"command": ["/Users/simon/RepoPrompt/repoprompt_cli", "repoprompt-mcp"],
"enabled": true
}
OpenCode version
0.15.8
Steps to reproduce
- Launch RepoPrompt & MCP server
- Add the config to opencode as mentioned above
- Launch opencode and send initial message to start a session
