- AlicenseNot gradedqualityBmaintenanceEnables AI agents to query Backstage catalog data as a typed graph over MCP, answering blast-radius, ownership and escalation, dependency, path, change-risk, and catalog-drift questions through bounded read-only tools.Apache 2.0
- AlicenseAqualityBmaintenanceOfficial SQAI MCP server: governed structured data access powered by Mojo kernels. 3 stdio tools: listSources (discovery), queryData (deterministic read-only queries + compute with provenance), explainQuery (dry-run validation). Introspection needs no credentials; execution requires a one-time free sqai login. npm: @thyn-ai/sqai-mcp. Source: packages/mcp. Registry: io.github.thyn-ai/sqai.4Apache 2.0
- FlicenseNot gradedqualityAmaintenanceEnables agents to gather bounded, reproducible runtime evidence by coordinating local profilers, benchmark tools, and trace processors against explicit artifacts or captured commands. It exposes typed analysis and capture operations over MCP that return provenance-tracked results inline, with optional durable preservation and replay of prior evidence.-
- AlicenseNot gradedqualityDmaintenanceExposes code graphs across multi-program repositories via MCP, enabling humans and agents to query the fleet with evidence.MIT
- AlicenseAqualityCmaintenanceExposes a materialized service dependency graph as an MCP toolset for persistent, queryable root-cause analysis via Cypher queries.51Apache 2.0
- AlicenseNot gradedqualityDmaintenanceProvides full lineage graph analysis for Power BI .pbix files, enabling source-to-visual-field traversal. Exposes REST and MCP endpoints for building, searching, and exporting lineage graphs.23 PyPIMIT

Scored across 6 tools
Most tools are clearly distinct: list_undeclared_sources and list_phantom_edges target different finding types, and get_incident_report and explain_verdict_semantics are self-contained. However, can_i_trust and get_integrity_score both address lineage trust at different granularities (asset verdict vs job score), which could cause an agent to misselect without careful reading.
Five of six tools follow a consistent snake_case verb_noun pattern (get_integrity_score, list_*, get_incident_report, explain_verdict_semantics). can_i_trust is also snake_case but is a question phrase rather than verb_noun, a minor deviation.
Six tools are well-scoped for a specialized lineage integrity server: they cover the core questions without redundancy. No unnecessary bloat or missing essential operation.
The surface covers the main analysis workflow: trust verdict, integrity score with components, undeclared sources, phantom edges, incident reports, and verdict semantics. Minor gaps remain (e.g., retrieving raw declared/observed edges for manual comparison), but agents can work around them via existing tools.
