 # MCP Clients Dataset
 
-This data contains clients logged by the MCP Server at `huggingface.co/mcp`.
+This data contains MCP Client identity and capability information logged by the MCP Server at `huggingface.co/mcp`. 
+
+The data is updated daily (~4AM UTC).
 
 ## Dataset Contents
 
-The dataset contains unique MCP client configurations with the following fields:
+The dataset contains two configurations, `raw` and `deduplicated`. 
+
+Raw contains distinct (name,version,capabilities) and a timestamp of the latest that distinct configuration was seen.
+
+Deduplicated removes `mcp-remote` suffixes, and concatenates the version numbers to contain distinct (name,capabilities) and a timestamp. Note that further post-processing may be added to handle specific clients such as `postman`.
 
 ### 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
+- **last_seen**: Most recent timestamp when this distinct client configuration 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
+- **last_seen**: Most recent timestamp when this distinct client configuration 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)
+- Some Clients only send capabilities that have been configured (for example, `fast-agent` only sends the `roots` capability if roots are 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.
+- The Protocol Version not currently captured - future datasets may include this
