List Servers
List the CI servers aggregated by rubyci.org. Use the returned id or name as the `server` argument of the other tools.
Current Status
Latest build result for each (server, branch, option) configuration within the last 14 days. Start here to see which configurations are currently failing.
Report History
Build history for a branch, newest first. Narrow by server and option to follow a single configuration over time.
Search Failures
Search log excerpts of failed builds (same index as https://rubyci.org/search). Use order=asc to find the earliest record of a failure. Excerpts exist only for failed builds on rubyci S3 servers and are pruned after about one year.
Find Failure Origin
Locate when a failure started and the suspect commit range. For each failing (server, branch, option) configuration, returns the first bad report, the last good report before it, and a github.com/ruby/ruby compare URL between the two commits when both are known. Without `query`, analyzes the current failing streak of each configuration; with `query`, tracks the earliest failure log matching that string (better for a specific test failure, tolerates flakiness). Feed compare_url to a GitHub MCP se
Failing Servers
Given a failure log substring (e.g. a test name or assertion message), list the (server, branch, option) configurations where that failure occurred, with first and last occurrence and whether the latest build of each configuration still has it. Distinguishes an environment-specific failure from a global regression.
Get Log Excerpt
Stored failure log excerpt (fail.txt + diff.txt, up to 100KB) for a report. Use `grep` to narrow to matching lines with context. Excerpts exist only for failed builds on rubyci S3 servers and are pruned after about one year; use the report's log_url for the full log.
Get your MCP into directories
A working endpoint is step one. Directory coverage is the coordinated launch across ChatGPT, Claude, Cursor, the MCP Registry, and community indexes.

Use the MCP endpoint listed on this page in your MCP client configuration. One-click install pills support Claude, Cursor, VS Code, and other hosts. Copy the remote MCP URL if your client needs a manual entry.
Operate rubyci.org? Verify ownership to take over this directory entry.
This server appears in the MCPBundles directory. Verify you operate it to take over the listing — name, description, logo, contact email, and skill content. We email a 6-digit code to a maintainer address your server publishes in /.well-known/security.txt or /.well-known/mcpbundles.json. Free, takes about a minute.
MCPBundles probed 7 tools on the live server. The tool list on this page reflects what was discovered at the last refresh — connect your client to see the full set available to your session.
No provider sign-in was required during MCPBundles' probe. Your client may still need MCPBundles credentials depending on how you connect.
