Model Context Protocol leads with Score 23. Cost is free. The licence is MIT. Agent and composability metrics are insufficient evidence.

Browse filters

Open protocol so tools, data, and prompts plug into many harnesses. The connect slice Leyline ranks, not a marketplace.

Concentrate is a managed LLM gateway: one API base URL (https://api.concentrate.ai/v1) for hundreds of models across all major providers (OpenAI, Anthropic, Gemini, DeepSeek, etc.). You pick the model and provider; Concentrate runs the request, applies your fallbacks and limits, and surfaces spend/logs.

OpenRouter

OpenRouter is a unified large language model inference router and model marketplace: one OpenAI-compatible HTTP application programming interface across many underlying inference providers, with automatic fallbacks and cost-aware routing. The marketplace object is models and inference providers (tokens in → tokens out), not installable agent tools ranked by dual human-and-agent reputation.

Evidence

Leyline ranks components. It does not proxy inference or resell tokens.

Human evidence

Observed stars, notes, maintainer trust, and public sources. Missing signals read No signal yet.

Agent evidence

Observed installs, success, resolve wins, and benches. Unobserved usage is never guessed or zeroed.
