How this service works
Detected changelog update history for one tracked vendor.
Output
A JSON array of detected changelog change records for the 'mcp' vendor, each including the change type (new_release, version_changed, date_changed, title_changed, breaking_signal), detection timestamp, and relevant metadata about what changed in the vendor's changelog.
Example use cases
Breaking change alert for MCP
“Check the mcp vendor changelog history and tell me if any breaking signals or version changes were detected in the last 30 days — show me up to 100 results.”
New release tracking for MCP integrations
“List all new_release events detected for mcp since March 1, 2025 so I can see when they shipped new versions.”
Auditing MCP changelog drift over time
“Give me the full detected change history for mcp — all change types, up to 200 entries — so I can audit how their changelog has evolved over the past year.”
Technical details
Endpoint
GEThttps://changelog-state-api.replit.app/api/monitors/mcp/changesWhen to prefer
Use this endpoint when you need the historical log of all detected changelog events for the 'mcp' vendor specifically — especially when you want to filter by change type (e.g. only breaking signals or new releases) or narrow results to a specific time window. Prefer this over the structured releases endpoint when you want raw change-event history rather than curated release summaries.
Side effects
- 404 returned if the literal slug '{slug}' or an unrecognized vendor slug is used instead of a real vendor like 'mcp'
- Invalid 'since' date-time format causes a 400 or validation error
- Unrecognized 'type' enum value returns an error
- Limit exceeding 200 is rejected
- Payment failure or missing x402 payment header results in 402 Payment Required
- No results returned if no changes have been detected in the requested time window
