# Allow MCP server to run without authentication
This PR enhances the MCP server to operate without requiring authentication, making it more flexible for environments where authentication isn't available or necessary. Key changes:
- Replaced `InitClient` with `TryInitClient` to allow the MCP server to start without credentials
- Added graceful handling when URL or authentication is missing
- Made authentication status visible in server logs
- Added logic to skip user-dependent tools when no authenticated user is present
- Made the `coder_report_task` tool available with just an agent token (no user token required)
- Added comprehensive tests to verify operation without authentication
These changes allow the MCP server to function in more environments while still using authentication when available, improving flexibility for CI/CD and other automated environments.
* Refactors toolsdk.Tools to remove opaque `map[string]any` argument in
favour of typed args structs.
* Refactors toolsdk.Tools to remove opaque passing of dependencies via
`context.Context` in favour of a tool dependencies struct.
* Adds panic recovery and clean context middleware to all tools.
* Adds `GenericTool` implementation to allow keeping `toolsdk.All` with
uniform type signature while maintaining type information in handlers.
* Adds stricter checks to `patchWorkspaceAgentAppStatus` handler.
https://github.com/coder/coder/pull/17163 introduced the
`workspace_app_statuses` table. Two of these fields
(`needs_user_attention`, `icon`) turned out to be surplus to
requirements.
- Removes columns `needs_user_attention` and `icon` from
`workspace_app_statuses`
- Marks the corresponding fields of `codersdk.WorkspaceAppStatus` as
deprecated.
Fixes two issues with the MCP server:
- Ensures we have a non-null schema, as the following schema was making
claude-code unhappy:
```
"inputSchema": { "type": "object", "properties": null },
```
- Skip adding the coder_report_task tool if an agent client is not
available. Otherwise the agent may try to report tasks and get confused.
- Refactors existing `mcp` package to use `kylecarbs/aisdk-go` and moves
to `codersdk/toolsdk` package.
- Updates existing MCP server implementation to use `codersdk/toolsdk`
