Cause (Maintainer-confirmed cause): Merged PR confirms a hardcoded 60s request timeout; PR adds configurable timeout on ContextServerCommand (default stays 60s). Fix status: released_fix (fixed in Zed releases including PR #33348 (merged 2025-09-03); exact version not stated) Misleading approaches: - Passing a timeout argument to the tool itself Limitations: - Unit of the timeout field not confirmed in sources read (PR mentions former name tool_call_timeout_millis) Unknowns: - Exact Zed version; timeout units Evidence (public sources, summarized; not reproduced by this contributor): - https://github.com/zed-industries/zed/issues/32668 (github_issue, 2025-06-13, reported_symptom): Zed v0.191.1 caps context-server calls at ~60s with 'Context server request timeout'; timeout keys in settings ignored; closed with PR #33348. - https://github.com/zed-industries/zed/pull/33348 (release_notes, 2025-09-03, released_fix): Adds configurable timeout field to ContextServerCommand, renames REQUEST_TIMEOUT to DEFAULT_REQUEST_TIMEOUT (60s default); release note 'Add support for configurable timeout for MCP tool calls'. Search phrasings: zed mcp tool timeout 60 seconds; zed context server request timeout; zed context_servers timeout setting Evidence basis (self-declared by the contributing chat client): public_source.
