This introduces a new command /mcp which you can manage MCPs on session level, makes it possible to have MCPs disabled by default and only enabling it when you want, for example my default i have github disabled and playwright enabled

Pull Request Overview

This PR introduces an MCP (Model Context Protocol) management UI accessible via the /mcp command, allowing users to enable/disable MCP servers on a session level rather than having all configured MCPs enabled by default.

Adds new API endpoints for connecting and disconnecting MCP servers dynamically
Implements a new TUI dialog component for managing MCP server states
Updates the MCP status logic to distinguish between disabled, connected, and failed states

This is beautiful, really needed.

Another thing, sometimes the agent is not familiar with the mcp servers it has available, I created a list-mcp tool for it to get rid of this issue, maybe something that should be there by default,

This is awesome! I was actually planning to request this feature too. It will really help to manage MCPs from the UI for each session. Nice to see someone already raised a PR for it. I’m interested in this feature and hope it gets merged soon.

@rekram1-node is this feature going to be added in the next release?

rekram1-node · 2025-11-24T05:08:29Z

Yeah this one looked pretty good, can we resolve the conflicts please?

dbpolito · 2025-11-24T12:49:54Z

@rekram1-node fixed 👍

modelnova-ai · 2025-11-26T10:57:19Z

@rekram1-node fixed 👍

Looks like there are conflicts again. Can you please resolve them when you get a chance?

dbpolito · 2025-11-26T11:51:35Z

conflicts fixed

Thanks, One question the toggle works on Space right now. Would it be better to use Enter to enable or disable an MCP instead of Space?

Space is mostly considered as an operation to "toggle" things.

IMO, space is better.

modelnova-ai · 2025-11-26T17:05:23Z

@rekram1-node Would really appreciate getting this merged! Managing multiple MCPs gets messy, and this toggle feature would be super helpful for reducing context bloat and improve startup time. Would be great to have this in the next release. Thanks! 🙏

rekram1-node · 2025-11-26T17:10:46Z

yeah we will merge dw

ocombe · 2025-12-04T09:25:13Z

That's awesome, I was just looking for this.
I have MCPs that I only use for some tasks (ex: notion MCP that I want to enable when I'm working on docs), but I don't want them to bloat the context all the time. This feature would fix that problem.

rekram1-node · 2025-12-08T04:15:07Z

Alright @dbpolito can you resolve the conflicts and then ill merge?

rekram1-node · 2025-12-08T04:15:29Z

I can't believe I commented two weeks ago, I thought I did that just a few days ago oof

- Merged upstream/dev into mcp_tui branch - Resolved conflicts in: - packages/opencode/src/cli/cmd/tui/app.tsx: Combined useConnected import with DialogMcp - packages/opencode/src/server/server.ts: Kept both MCP connect/disconnect endpoints and new OAuth auth endpoints - packages/sdk/js/src/gen/sdk.gen.ts: Added all MCP SDK methods (connect, disconnect, and OAuth auth) - packages/sdk/js/src/gen/types.gen.ts: Added all MCP TypeScript type definitions - All merge conflicts resolved successfully

dbpolito · 2025-12-08T14:34:18Z

@rekram1-node hey, updated the PR... it seems format and sdk actions are conflicting with each other... i ran their scripts locally but or one or another fails...

rekram1-node · 2025-12-08T17:22:53Z

Don't worry about them they suck, Dax will fix it
