About 0Latency
0Latency is a multi-tenant memory API for AI agents, with an MCP server package for connecting agents to persistent memory. It supports semantic recall, automatic deduplication, and knowledge graphs.
Key features
- 01Store memories across sessions
- 02Recall memories with semantic search
- 03Automatically deduplicate similar memories
- 04Support knowledge graphs
- 05Isolate storage by tenant
Use cases
- 01Keep agent context between sessions
- 02Recall relevant memories by meaning
- 03Reduce duplicate stored memories
MCP support
The @0latency/mcp-server package exposes 0Latency's memory API to MCP clients. It uses an API key supplied through the ZERO_LATENCY_API_KEY environment variable.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
