01Record Cursor version and index status
Capture the installed version, account state, workspace path, and current indexing message.
What the result tells you: A version-specific or service-side issue should not be treated as project corruption.
ERR-756/Cursor · Codebase indexing stuck
Appears when: Codebase indexing stuck
Cursor codebase indexing is stuck or not working
Indexing can stall because the workspace is too broad, dominated by generated or binary files, unavailable through filesystem permissions, blocked by network or account state, or held by stale local index data. Preserve the project, narrow the workspace, inspect status, and rebuild the index only after excluding noise.
How do I fix cursor codebase indexing is stuck or not working?
01
# Back up workspace settingsRecord exclusions and project-specific configuration before resetting anything.02
# Exclude generated and irrelevant pathsKeep source, schemas, and important documentation; remove dependencies, outputs, caches, logs, and large artifacts from scope.03
# Restart with a clean, reachable workspaceResolve filesystem or network access and reopen the intended repository root.04
# Rebuild once and verify retrievalAfter the workspace is clean, rebuild the index and test known symbols and recently changed files.Preserve the current working revision, change one proven boundary, and verify the published path in a clean session.
What if the quick fix does not work?
02Inspect workspace size and noise
Identify generated builds, dependencies, caches, logs, large assets, and nested repositories.
What the result tells you: Indexing unnecessary files increases time and can hide the files that matter.
03Check file access and workspace boundaries
Confirm Cursor can read the relevant directories and the intended repository is opened at the correct root.
What the result tells you: Permission-denied or remote-filesystem issues prevent a complete index.
04Test a small representative workspace
Open a clean subset or small repository under the same account and network.
What the result tells you: If a small workspace indexes, project scope or files are more likely than the client installation.
| Likely cause | What proves it | First safe action |
|---|---|---|
| Workspace includes too much generated content | A version-specific or service-side issue should not be treated as project corruption. | Back up workspace settings |
| Filesystem access is incomplete | Indexing unnecessary files increases time and can hide the files that matter. | Exclude generated and irrelevant paths |
| Stale local index state | Permission-denied or remote-filesystem issues prevent a complete index. | Restart with a clean, reachable workspace |
| Client, account, or network issue | If a small workspace indexes, project scope or files are more likely than the client installation. | Rebuild once and verify retrieval |
Why do AI-built apps hit this problem?
Indexing can stall because the workspace is too broad, dominated by generated or binary files, unavailable through filesystem permissions, blocked by network or account state, or held by stale local index data. Preserve the project, narrow the workspace, inspect status, and rebuild the index only after excluding noise.
Workspace includes too much generated content
Dependencies, build output, caches, and binaries overwhelm useful indexing work.
Filesystem access is incomplete
The app cannot read part of the repository or a remote mount behaves inconsistently.
Stale local index state
The index no longer reflects the current workspace or was interrupted.
When the built-in AI fix makes it worse
Freeze generated changes, restore the last known working version, reproduce one request, collect the browser and platform logs, and change one layer at a time.
How do I stop this problem recurring?
- →Maintain index exclusions with the repository, not only on one developer machine.
- →Keep generated assets outside source directories where possible.
- →Keep production configuration in an explicit release checklist, not in chat history.
- →Test the published URL in a clean browser session before calling the release complete.
- →Keep a last-known-good deployment and a documented rollback step.
- →Log the critical request path with enough context to identify the failing layer.

Cursor codebase indexing is stuck or not working questions
Should node_modules and build output be indexed?+
Usually no. Excluding generated and dependency directories keeps the index focused on code your team owns.
Will reinstalling Cursor fix indexing?+
Only if the client installation is the cause. First test a small workspace and inspect permissions, scope, version, and status.
When should I rebuild the index?+
After correcting exclusions, workspace root, access, or a confirmed stale state. Repeated resets without changing the cause waste time.
