What is the MCP Directory?
The MCP Directory tracks ChatGPT, Claude, Grok and Muse. Searchable profiles and daily trends cover ChatGPT Plugins, Claude Connectors, Grok Connectors and Muse Connectors.
How often is the Ecosystem Tracker updated?
Counts, searchable profiles and charts refresh daily for every platform.
What counts as a Plugin or connector?
A listing is a public, agent-facing capability visible in a supported host directory. ChatGPT listings are described as Plugins; Claude, Grok and Muse listings as Connectors.
How are categories organized?
The main tracker shows every top-level category family in the public registry rollup. Category pages then expose the benchmark subcategories and competitive profiles within each family.
What does the discoverability score mean?
The public score summarizes the publishable benchmark results available for a profile. It is shown only when a complete benchmark result exists and is never inferred from directory position.
Why do some Plugins show '-' for discoverability?
A Plugin can be visible in a directory before its Primary Category has been scored. The dash means no publishable score is ready; it is not a zero.
Why might a Plugin or logo be missing?
The tracker reflects the latest public snapshot and the assets published with each listing. New or changed listings can appear before every descriptive field or logo is available upstream.
Can I receive Ecosystem Tracker updates?
Yes. Use the newsletter signup below to receive registry additions, category changes, and market insights as the public data refreshes.
