## Support semantics
This is a **candidate / unverified** Solution from the KFA Solution Factory Tier-2 gate. It is source-grounded research material, not an Outcome, and does **not** claim independent reproduction or confirmed field success.
## Cause
Zed context_server client used a hardcoded DEFAULT_REQUEST_TIMEOUT of 60 seconds for MCP requests; PR #33348 wires ContextServerCommand.tool_call_timeout_millis into the client request_timeout.
## Steps
1. Confirm the error occurs near 60s regardless of tool-specific timeout parameters.
2. Update Zed to a version containing merged PR #33348.
3. Add tool_call_timeout_millis to the context server command configuration in settings.
4. Retry the long-running tool; if still timing out, verify the MCP server itself is not imposing a shorter limit.
## Expected result
Context server client uses the configured request timeout instead of the hardcoded 60s default for MCP JSON-RPC requests.
## Misleading approaches
- Passing a timeout only to the MCP tool invocation without configuring Zed context server command timeout.
- Expecting pre-33348 builds to honor settings-only timeout changes.
## Limitations
- Exact first Zed release version number containing the fix not stated in PR metadata alone.
- Unit of tool_call_timeout_millis assumed milliseconds from field name and Cline reference in PR; not independently verified in settings docs here.
## Unknowns
- Minimum Zed release tag shipping PR #33348.
- Whether all transport paths share the same timeout configuration.
## Evidence claims
- (documented_platform_behavior) Zed context server MCP client defaults to a 60-second request timeout. — https://raw.githubusercontent.com/zed-industries/zed/main/crates/context_server/src/client.rs
- (released_fix) PR #33348 adds configurable tool_call_timeout_millis and uses it instead of a fixed REQUEST_TIMEOUT. — https://github.com/zed-industries/zed/pull/33348
Proposed approach
- Problem id
- edda8719-49da-45e7-bbef-f0a8193f7acb
- Proposed action
- Upgrade Zed to a release that includes PR #33348 (merged 2025-09-03). In context server settings, set tool_call_timeout_millis on the ContextServerCommand to exceed 60000 when long-running MCP tools are expected. Default remains 60 seconds if unset.
