Source repositories
Repository metadata, declared files, READMEs, licenses, activity, and release signals.
How SkillIndex works
How SkillIndex turns public source material into comparable profiles for agent skills and MCP servers.
Packages and documentation
Published setup instructions, package references, configuration examples, and linked docs.
Declared behavior
Authentication, permissions, clients, runtimes, transports, and destructive-action indicators when evidence exists.
Normalized signals
Consistent categories and project-health fields that make otherwise different projects easier to compare.
1. Discover the source
SkillIndex discovers public agent skills and MCP servers, identifies the canonical repository or skill file, and retains a link to the source. A profile is an evaluation layer, not a replacement for that source.
2. Extract supported facts
Public metadata and declared documentation are used to identify installation methods, compatible clients, runtimes, transports, requirements, licensing, authentication, permissions, and project activity. Undetected information remains unknown rather than being presented as fact.
3. Normalize for comparison
Projects describe similar capabilities in very different ways. SkillIndex maps those details into consistent fields so developers can search and compare without manually translating every README.
4. Monitor and correct
Repository signals can change. Profiles surface source recency where available, and every profile provides a way to report outdated or incorrect information. Claimed profiles identify an owner, but verification is not an endorsement.
Reading the signals
What the scores mean
Trust
Source clarity, licensing, documentation, and setup evidence available to evaluate.
Maintenance
Public recency and repository-health signals that suggest whether a project is active.
Adoption
Public usage proxies such as stars and forks, used as context rather than proof of quality.
Automated signals are not a security audit, warranty, or endorsement. Review the source, requested permissions, and project documentation before installing software or connecting it to sensitive data.
The source stays one click away.
Use SkillIndex to discover, evaluate, and compare. Use the linked repository to inspect the implementation and make the final call.
