No score, grade or rank, and not in the rankings until the panel reviews it. How the index works: https://www.anchorterminal.com/indexed/ - Kind: MCP server, by llmlatency.dev (https://llmlatency.dev) - Category: Observability & incidents (https://www.anchorterminal.com/categories/observability.md) - Listed because: It's published in the registry under llmlatency.dev, a namespace the registry only gives to whoever proves they control that domain. - What the official MCP registry says: Measured latency, time to first token and uptime for ~45 AI inference APIs, by region. ## Facts - MCP registry: `dev.llmlatency/llm-latency-tracker` 1.1.0 - Endpoint: https://llmlatency.dev/mcp (streamable HTTP) - Source: https://github.com/mazamaka/llm-latency-tracker - Website: https://llmlatency.dev - GitHub stars: 2 - Registry entry updated: 2026-08-16 ## Tools - Tools it lists (2, about 188 tokens of context, `tools/list` without credentials, checked 2026-10-04 22:24 UTC): - `get_ai_api_latency`: Measured latency (TTFB p50/p95) and uptime rankings of AI inference API providers by region, from llmlatency.dev. - `get_model_deprecations`: AI model deprecation calendar: announced and shutdown dates, replacement models, and how many days of migration notice each provider actually gives… - How its tools read to an agent (0 errors, 2 warnings, 1 note, about 188 tokens; rules at https://www.anchorterminal.com/check.md; not part of the score): - warn TC16 get_ai_api_latency: no readOnlyHint or destructiveHint - warn TC16 get_model_deprecations: no readOnlyHint or destructiveHint - note TC24 server: 2 of 2 tools have no outputSchema - JSON: https://www.anchorterminal.com/api/v1/tools/llmlatency-llm-latency-tracker.json - Being indexed says nothing about quality, and nobody can pay for it.
