Runtime Fault Taxonomy for Model Context Protocol Servers

Joshua OWOTOGBE's replication package for a taxonomy of runtime faults in Model Context Protocol servers, published on figshare in June 2026. It contains artifacts from analyzing 837 confirmed fault threads from 473 GitHub repositories and validating the taxonomy via a survey of 55 MCP developers.

Use Cases

• Validate taxonomy of runtime faults based on manual coding records and survey responses.
• Analyze patterns in software faults based on mined GitHub issue and pull-request data.
• Replicate data-processing pipeline for empirical software engineering studies using the provided Python notebook.
• Study developer perceptions of faults based on practitioner survey data.

Strengths

• Dataset is derived from 837 confirmed fault threads, providing a substantial empirical basis.
• Validation includes survey responses from 55 MCP server developers.
• Package includes a detailed README.md describing structure, contents, and pipeline stages.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal and source bias inherent to GitHub repositories mined in 2026.
