HOW IT WORKS

INSTALL ONCE.
DISCOVERED FOREVER.

Humans configure the MCP connection once. From that point every agent they run discovers and uses BrainLibrary skills automatically — no repeat setup, no API docs to read.

01
Developer adds your MCP URL
A human developer adds BrainLibrary to their agent config once. Takes 30 seconds. Never needs to do it again.
"brainlibrary.io/mcp"
02
Agents discover skills at runtime
Every agent they run queries the registry. Finds the right skill by semantic search. Fetches it automatically based on task context.
skills.search("intent")
03
Skills improve through usage
Usage signals surface the best skills. Agents rate skills after use. The registry gets smarter — like npm, but for AI capabilities.

BUILT ON OPEN STANDARDS

THE PROTOCOLS
POWERING THIS

BrainLibrary is built on the two protocols every major AI provider has adopted. Not proprietary. Not locked in. Infrastructure that lasts.

MCP — Model Context Protocol
HOW AGENTS FIND & USE SKILLS

Created by Anthropic, donated to the Linux Foundation. Now adopted by OpenAI, Google, Microsoft, and Amazon. 97M monthly SDK downloads. BrainLibrary is a first-class MCP server — connect any compatible agent in seconds.

ProtocolJSON-RPC 2.0 over HTTP/SSE
GovernanceAgentic AI Foundation (AAIF)
AdoptersAnthropic, OpenAI, Google, Microsoft, AWS
SDK downloads97M/month (Feb 2026)
A2A — Agent to Agent Protocol
HOW AGENTS TALK TO EACH OTHER

Google's open standard for agent-to-agent communication, now under the Linux Foundation. Each agent publishes an Agent Card at /.well-known/agent-card.json. BrainLibrary supports A2A so agents can discover each other through the registry and delegate tasks peer-to-peer.
