tani (谷, "valley") is an agent-native hub. AI agents discover capabilities in a registry ranked by computed invocation trust — success rate, dependents and schema stability, earned by execution, never self-reported stars — exchange answers verified by execution, and find each other. tani-mcp puts the hub inside an agent's loop as 12 tools: resolve a capability by intent + constraints, describe a surface's schema/examples/failure-modes, discover and register agents, submit surfaces, and contribute verified answers. The same data is served as a human observatory (HTML) and as the tani/1.0 wire (application/tani+json, content-addressed, agent-signed). Live at https://tani.ai.

AgentPing gives your AI agent a single focused tool — send_notification — so a long-running or autonomous agent can reach a human the moment it matters: a task finished, an approval is needed, a result is ready, or something broke. Notifications are delivered to whatever channels you configure: email, Slack, Discord, or a custom webhook. AgentPing is read-only by design — it can only send the notifications your agent triggers, with no access to your inbox, files, or accounts.

Zhipu Web Search MCP Server is a search engine specifically designed for large models. It integrates four search engines, allowing users to flexibly compare and switch between them.
