Cost limits of UEFN MCP reads: which calls return huge payloads and how to filter them. Use before any potentially large read.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# uefn-mcp-heavy-calls
## Measured costs
| Call | Payload | Rule |
|---|---|---|
| `find_assets` without filters | ~120 MB | NEVER |
| `find_assets` StaticMesh/NiagaraSystem without filters | ~1.7 MB | always `folder_path` + `asset_type` |
| recursive `list_folders` on the root | ~2 MB | non-recursive, narrow `root_path` |
| `GetLogEntries maxEntries 0` | ~2.4 MB | always `pattern` |
| `ObjectTools/list_properties` on a mesh component | ~55 KB | `get_properties` with one name |
| `GetLogCategories` | ~125 KB | avoid |
| `GetEmitterTopology` | ~56 KB | only if needed |
## Filters
Always `folder_path`, `name`, `asset_type`, `pattern`. Paths in GUID form `/<guid>/<project>/...`.
## Verified recipes
- `AssetTools/find_assets {"folder_path":"{lab_mount}/X","asset_type":{"refPath":"/Script/Engine.DataTable"},"recursive":true}`.
- `AssetTools/list_folders {"root_path":"{lab_mount}/X","recursive":false}`.
- `GetLogEntries#filter_noise`, `GetLogEntries#why_startsession_failed`.
- `execute_tool_script#batch_reads` to group small reads.

How to install
mdr add mimmo-the-root/uefn-dream-bot-team/uefn-mcp-heavy-calls@sha256:1d96819ed98ab47bThe line at the top of this page pins the label git:20261016.5b4e0c6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
