Major Labs
Description
Open agentic-web datasets: Agent Trust Index, MCP stats, incident timeline. Read-only, CC-BY-4.0.
What our measurements say
Major Labs is a remote MCP server published at majorlabs.co. It has been probed 16 times since 9/12/2026. It answered in 16 of them (100.0%), a near-uninterrupted record. Median response time is 1,632 ms, a delay an agent will notice. It offers a narrow, focused set of 5 tools. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.
Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Tool names clearly indicate their purpose (e.g., 'get_trust_index' for trust scores).
- Distinct tool functions avoid overlap (e.g., 'list_incidents' vs. 'get_threshold_watch').
Weaknesses
- Descriptions focus on 'what' rather than 'when' to use tools (e.g., no guidance on incident filtering).
- No explicit error handling or constraint documentation in tool descriptions.
get_trust_index— Description lacks clarity on when to use the composite score vs. per-pillar metrics.get_threshold_watch— No mention of how to interpret framework change events or error scenarios.

Tools
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
get_trust_indexThe weekly Agent Trust Index: one composite score (0-100) for how safe the agentic web is to transact on, fused from code-safety, identity, and supply-chain pillars, with the per-pillar numbers and methodology version.
get_mcp_ecosystem_statsAggregate statistics from the Major Labs weekly sweep of the MCP server ecosystem: census size, activity, transport and language breakdowns, and security/identity aggregates. Firsthand, read-only measurement.
list_incidentsA dated, sourced record of frontier AI control incidents: containment escapes, unsanctioned live-system actions, evaluation incidents, and insider disclosures, with published inclusion criteria and sources for every claim.
get_agent_identity_trackerEvery announced framework, protocol, standard, and regulation for AI agent identity, delegation, and know-your-agent (KYA) verification, dated and traced to primary sources.
get_threshold_watchDated, hashed snapshots of the frontier labs' published safety frameworks, with diffs when a framework changes. A change event means a lab edited its safety commitments.
