# MCP Clients Dataset |
|
|
|
|
|
This data contains clients logged by the MCP Server at `huggingface.co/mcp`. |
|
|
|
|
|
## Dataset Contents |
|
|
|
|
|
The dataset contains unique MCP client configurations with the following fields: |
|
|
|
|
|
### Raw Split (`raw`) |
|
|
- **name**: MCP client name (e.g., "Cursor", "Anthropic/ClaudeAI", "chat-ui-mcp") |
|
|
- **version**: Client version |
|
|
- **capabilities**: Client capabilities (JSON string) |
|
|
- **last_seen**: Most recent timestamp when this client was seen |
|
|
|
|
|
### Deduplicated Split (`deduplicated`) |
|
|
- **name**: MCP client name (normalized, mcp-remote suffix stripped) |
|
|
- **versions**: All versions seen for this client (comma-separated) |
|
|
- **capabilities**: Client capabilities (JSON string) |
|
|
- **last_seen**: Most recent timestamp when this client was seen |
|
|
|
|
|
## Notes about the Data |
|
|
|
|
|
- Some Clients only send capabilities that have been configured (for example, `fast-agent` only sends the `roots` capability if they have been configured) |
|
|
- There are a number of capabilities out of specification that are helpful to track (e.g. MCP-UI, Skybridge, Apps SDK). We encourage the use of `experimental` to advertise these capabilities for tracking. |
|
|
- The data is extracted from the `evalstate/hf-mcp-logs` dataset, filtering for `initialize` method calls and tracking the most recent `last_seen` timestamp for each unique client configuration. |
|
|
- The `deduplicated` split groups clients by (name, capabilities), concatenating all versions together. |
|
|
|
|
|
## Usage |
|
|
|
|
|
```python |
|
|
from datasets import load_dataset |
|
|
|
|
|
# Load raw clients |
|
|
raw_ds = load_dataset('evalstate/mcp-clients', 'raw') |
|
|
for client in raw_ds['raw']: |
|
|
print(f"{client['name']} v{client['version']}") |
|
|
|
|
|
# Load deduplicated clients |
|
|
dedup_ds = load_dataset('evalstate/mcp-clients', 'deduplicated') |
|
|
for client in dedup_ds['deduplicated']: |
|
|
print(f"{client['name']}: {client['versions']}") |
|
|
``` |
|
|
|
|
|
## Updating the Dataset |
|
|
|
|
|
The dataset is kept up-to-date via Hugging Face Jobs: |
|
|
|
|
|
1. **Extract step** (`raw` split): |
|
|
```bash |
|
|
uv run https://huggingface.co/datasets/evalstate/mcp-clients/resolve/main/extract_mcp_clients.py --push-to-hub --split raw |
|
|
``` |
|
|
|
|
|
2. **Deduplicate step** (`deduplicated` split): |
|
|
```bash |
|
|
uv run https://huggingface.co/datasets/evalstate/mcp-clients/resolve/main/deduplicate_clients.py --push-to-hub |
|
|
``` |
