- Add migration to remove `source` tag because `ContextServerSettings`
is now untagged
- Fix typos in context server modal
- PR seems to have removed the `test_action_namespaces` test, which I
brought back in this PR
Release Notes:
- Fixed an issue where the `source` property of MCP settings would show
up as unrecognised
This PR adds back the footer with the "Configure" button in the model
selector but only when the seeing it from the Zed agent (or inline
assistant/text threads). I had removed it a while back because seeing
the "Configure" button, which takes you to the agent panel settings
view, when clicking from an external agent didn't make much sense, given
there's nothing model-wise you can configure from Zed (at least yet) for
an external agent.
This also makes the button in the footer a bit nicer by making it full
screen and displaying a keybinding, so that you can easily do the whole
"trigger model selector → go to settings view" all with the keyboard.

Release Notes:
- N/A
### What this solves
This PR adds support for HTTP and SSE (Server-Sent Events) transports to
Zed's context server implementation, enabling communication with remote
MCP servers. Currently, Zed only supports local MCP servers via stdio
transport. This limitation prevents users from:
- Connecting to cloud-hosted MCP servers
- Using MCP servers running in containers or on remote machines
- Leveraging MCP servers that are designed to work over HTTP/SSE
### Why it's important
The MCP (Model Context Protocol) specification includes HTTP/SSE as
standard transport options, and many MCP server implementations are
being built with these transports in mind. Without this support, Zed
users are limited to a subset of the MCP ecosystem. This is particularly
important for:
- Enterprise users who need to connect to centralized MCP services
- Developers working with MCP servers that require network isolation
- Users wanting to leverage cloud-based context providers (e.g.,
knowledge bases, API integrations)
### Implementation approach
The implementation follows Zed's existing architectural patterns:
- **Transports**: Added `HttpTransport` and `SseTransport` to the
`context_server` crate, built on top of the existing `http_client` crate
- **Async handling**: Uses `gpui::spawn` for network operations instead
of introducing a new Tokio runtime
- **Settings**: Extended `ContextServerSettings` enum with a `Remote`
variant to support URL-based configuration
- **UI**: Updated the agent configuration UI with an "Add Remote Server"
option and dedicated modal for remote server management
### Changes included
- [x] HTTP transport implementation with request/response handling
- [x] SSE transport for server-sent events streaming
- [x] `build_transport` function to construct appropriate transport
based on URL scheme
- [x] Settings system updates to support remote server configuration
- [x] UI updates for adding/editing remote servers
- [x] Unit tests using `FakeHttpClient` for both transports
- [x] Integration tests (WIP)
- [x] Documentation updates (WIP)
### Testing
- Unit tests for both `HttpTransport` and `SseTransport` using mocked
HTTP client
- Manual testing with example MCP servers over HTTP/SSE
- Settings validation and UI interaction testing
### Screenshots/Recordings
[TODO: Add screenshots of the new "Add Remote Server" UI and
configuration modal]
### Example configuration
Users can now configure remote MCP servers in their `settings.json`:
```json
{
"context_servers": {
"my-remote-server": {
"enabled": true,
"url": "http://localhost:3000/mcp"
}
}
}
```
### AI assistance disclosure
I used AI to help with:
- Understanding the MCP protocol specification and how HTTP/SSE
transports should work
- Reviewing Zed's existing patterns for async operations and suggesting
consistent approaches
- Generating boilerplate for test cases
- Debugging SSE streaming issues
All code has been manually reviewed, tested, and adapted to fit Zed's
architecture. The core logic, architectural decisions, and integration
with Zed's systems were done with human understanding of the codebase.
AI was primarily used as a reference tool and for getting unstuck on
specific technical issues.
Release notes:
* You can now configure MCP Servers that connect over HTTP in your
settings file. These are not yet available in the extensions API.

## Summary
Fixes#42342
When installing a dev extension with long installation instructions, the
configuration modal would overflow and users couldn't scroll to see the
full content or interact with buttons at the bottom.
## Solution
This PR adds a `ScrollHandle` to the `ConfigureContextServerModal` and
passes it to the `Modal` component, enabling the built-in modal
scrolling capability. This ensures all content remains accessible
regardless of length.
## Changes
- Added `ScrollHandle` import to the ui imports
- Added `scroll_handle: ScrollHandle` field to
`ConfigureContextServerModal` struct
- Initialize `scroll_handle` with `ScrollHandle::new()` when creating
the modal
- Pass the scroll handle to `Modal::new()` instead of `None`
## Testing
- Built the changes locally
- Tested with extensions that have long installation instructions
- Verified scrolling works and all content is accessible
- Confirmed no regression for extensions with short descriptions
Release Notes:
- Fixed scrolling issue in extension configuration modal when
installation instructions overflow the viewport

Closes#39172
This refactors when we resolve UI keybindings in an effort to reduce
flickering whilst painting these: Previously, we would always resolve
these upon creating the binding. This could lead to cases where the
corresponding context was not yet available and no binding could be
resolved, even if the binding was then available on the next presented
frame. Following that, on the next rerender of whatever requested this
keybinding, the keybind for that context would then be found, we would
render that and then also win a layout shift in that process, as we went
from nothing rendered to something rendered between these frames.
With these changes, this now happens less often, because we only look
for the keybinding once the context can actually be resolved in the
window.

Also reduced cloning in the keymap editor in this process, since that
requiered changing due to this anyway.
Release Notes:
- Fixed some cases where keybinds would appear with a slight delay,
causing a flicker in the process
In practice this just hides the web search tool when not using the Zed
provider
Release Notes:
- Fixed an issue where the web search tool would show up in the profile
selector even when not using a model via Zed Pro
In the process of adding pickers for the theme and icon themes fields in
the settings UI, I felt like there was an improvement opportunity in
regards to where some of these components are stored. The `ui_input`
crate originally was meant only for the text field-like component, which
couldn't be in the regular `ui` crate due to the dependency with
`editor`. Given we had also added the number field there—which is
similar in also having the same dependency—it made sense to think of
this crate more like a home for form-like components rather than for
only one component.
However, we were also storing some settings UI-specific stuff in that
crate, which didn't feel right. So I ended up creating a new directory
within the `settings_ui` for components and moved all the pickers and
the custom input field there. I think this makes it for a cleaner
structure.
Release Notes:
- settings_ui: Added the ability to search for theme and icon themes in
their respective fields.
Release Notes:
- Added Codestral edit predictions provider which can be enabled by adding an API key in the Mistral section of agent settings.
## Config
Get API key from https://console.mistral.ai/codestral and add it in the Mistral section of the agent settings.
```

"edit_prediction_provider": "codestral"
},
"edit_predictions": {

This PR makes sections in the AI settings UI more consistent with each
other and also just overall simpler. One of the main changes here is
adding the tools from a given MCP server in a modal (as opposed to in a
disclosure within the settings view). That's mostly an artifact of
wanting to make all of the items within sections look more of the same.
Then, in the process of doing so, also changed the logic that we were
using to display MCP servers; previously, in the case of extension-based
servers, we were only showing those that were _configured_, which felt
wrong because you should be able to see everything you have _installed_,
despite of its status (configured or not).
However, there's still a bit of a bug (to be solved in a follow-up PR),
which already existed but it was just not visible given we'd only
display configured servers: an MCP server installed through an extension
stays as a "custom server" until it is configured. If you don't
configure it, you can't also uninstall it from the settings view (though
it is possible to do so via the extensions UI).
Release Notes:
- agent: Improve settings view UI and solve issue where MCP servers
would get unsorted upon turning them on and off (they're all
alphabetically sorted now).
This removes the `gemini-and-native` and `claude-code` feature flags.
Also, I removed a bunch of unused agent1 code that we do not need
anymore.
Initially I wanted to remove much more of the `agent` code, but noticed
some things that we need to figure out first:
- The inline assistant + context strip use `Thread`/`ContextStore`
directly
- We need some replacement for `ToolWorkingSet`, so we can access
available tools (as well as context server tools) in other places, e.g.
the agent configuration and the configure profile modal
Release Notes:
- N/A
This PR fixes an issue where extension operations would never show in
the activity indicator despite this being implemented for ages. This
happened because we were always returning `None` whenever the app has a
global auto updater, which is always the case, so the code path for
showing extension updates in the indicator could never be hit despite
existing prior. Also slightly improves the messages shown for ongoing
extension operations, as these were previously context unaware.
While I was at this, I also quickly took a stab at cleaning up some
remotely related stuff, namely:
- The `AnimationExt` trait is now by default only implemented for
anything that also implements `IntoElement`. This prevents
`with_animation` from showing up for e.g. `u32` within the suggestions
(finally).
- Commonly used animations are now implemented in the
`CommonAnimationExt` trait within the `ui` crate so the needed code does
not always need to be copied and element IDs for the animations are
truly unique.
Relevant change here regarding the original issue is the change from the
`return match` to just a `match` within the activitiy indicator, which
solved the issue at hand.
If we find this to be too noisy at some point, we can easily revisit,
but I think this holds important enough information to be shown in the
activity indicator, especially whilst developing extensions.
Release Notes:
- Extension installation and updates will now be shown in the activity
indicator.
This removes around 900 unnecessary clones, ranging from cloning a few
ints all the way to large data structures and images.
A lot of these were fixed using `cargo clippy --fix --workspace
--all-targets`, however it often breaks other lints and needs to be run
again. This was then followed up with some manual fixing.
I understand this is a large diff, but all the changes are pretty
trivial. Rust is doing some heavy lifting here for us. Once I get it up
to speed with main, I'd appreciate this getting merged rather sooner
than later.
Release Notes:
- N/A
This PR refactors the callout component and improves how we display
errors and warnings in the agent panel, along with improvements for
specific cases (e.g., you have `zed.dev` as your LLM provider and is
signed out).
Still a work in progress, though, wrapping up some details.

### TL;DR
* Adds `capabilities` configuration for OpenAI-compatible models
* Relates to
https://github.com/zed-industries/zed/issues/36215#issuecomment-3193920491
### Summary
This PR introduces support for configuring model capabilities for
OpenAI-compatible language models. The implementation addresses the
issue that not all OpenAI-compatible APIs support the same features -
for example, Cerebras' API explicitly does not support
`parallel_tool_calls` as documented in their [OpenAI compatibility
guide](https://inference-docs.cerebras.ai/resources/openai#currently-unsupported-openai-features).
### Changes
1. **Model Capabilities Structure**:
- Added `ModelCapabilityToggles` struct for UI representation with
boolean toggle states
- Implemented proper parsing of capability toggles into
`ModelCapabilities`
2. **UI Updates**:
- Modified the "Add LLM Provider" modal to include checkboxes for each
capability
- Each OpenAI-compatible model can now be configured with its specific
capabilities through the UI
3. **Configuration File Structure**:
- Updated the settings schema to support a `capabilities` object for
each `openai_compatible` model
- Each capability (`tools`, `images`, `parallel_tool_calls`,
`prompt_cache_key`) can be individually specified per model
### Example Configuration
```json
{
"openai_compatible": {
"Cerebras": {
"api_url": "https://api.cerebras.ai/v1",
"available_models": [
{
"name": "gpt-oss-120b",
"max_tokens": 131000,
"capabilities": {
"tools": true,
"images": false,
"parallel_tool_calls": false,
"prompt_cache_key": false
}
}
]
}
}
}
```
### Tests Added
- Added tests to verify default capability values are correctly applied
- Added tests to verify that deselected toggles are properly parsed as
`false`
- Added tests to verify that mixed capability selections work correctly
Thanks to @osyvokon for the desired `capabilities` configuration
structure!
Release Notes:
- OpenAI-compatible models now have configurable capabilities (#36370;
thanks @calesennett)

This is really just a small beginning, as there are many other icons to
be revised and cleaned up. Our current set is a bit of a mess in terms
of dimension, spacing, stroke width, and terminology. I'm sure there are
more non-used icons I'm not covering here, too. We'll hopefully tackle
it all soon leading up to 1.0.

Closes#32354
The issue is that we render selections over the text in the agent panel,
but under the text in editor, so themes that have no alpha for the
selection background color (defaults to 0xff) will just occlude the
selected region. Making the selection render under the text in markdown
would be a significant (and complicated) refactor, as selections can
cross element boundaries (i.e. spanning code block and a header after
the code block).
The solution is to add a new highlight to themes
`element_selection_background` that defaults to the local players
selection background with an alpha of 0.25 (roughly equal to 0x3D which
is the alpha we use for selection backgrounds in default themes) if the
alpha of the local players selection is 1.0. The idea here is to give
theme authors more control over how the selections look outside of
editor, as in the agent panel specifically, the background color is
different, so while an alpha of 0.25 looks acceptable, a different color
would likely be better.

Clearly, the selection in the after doesn't look _that_ great, but it is
better than the before, and this PR makes the color of the selection
configurable by the theme so that this theme author could make it a
lighter color for better contrast.

This cleans up our settings to not include any `version` fields, as we
have an actual settings migrator now.
This PR removes `language_models > anthropic > version`,
`language_models > openai > version` and `agent > version`.
We had migration paths in the code for a long time, so in practice
almost everyone should be using the latest version of these settings.
Release Notes:
- Remove `version` fields in settings for `agent`, `language_models >
anthropic`, `language_models > openai`. Your settings will automatically
be migrated. If you're running into issues with this open an issue
[here](https://github.com/zed-industries/zed/issues)
This PR moves the UI-dependent logic in the `agent` crate into its own
crate, `agent_ui`. The remaining `agent` crate no longer depends on
`editor`, `picker`, `ui`, `workspace`, etc.
This has compile time benefits, but the main motivation is to isolate
our core agentic logic, so that we can make agents more
pluggable/configurable.
