Agent Network Protocol (ANP) vs Model Context Protocol (MCP)
The map lists them as complementary: sites and agents commonly implement both. They answer different questions: Agent Network Protocol is a step 6 (Coordinate) standard, Model Context Protocol step 5 (Act), so they are not substitutes.
| Agent Network Protocol ANP | Model Context Protocol MCP | |
|---|---|---|
| Lifecycle step | 6 Coordinate: Talk to another agent | 5 Act: Do something for me |
| Answers | How can decentralized agents from different platforms authenticate, discover, and message each other without a central registry? | How does an AI application call tools and pull structured context, prompts, and data from an external server? |

When to use which
- Choose Agent Network Protocol when your question is “How can decentralized agents from different platforms authenticate, discover, and message each other without a central registry?” and you accept its maturity: status "Released v1.2 (core suite); meta-protocol (ANP-06) remains draft/unreleased", implementation shipping.
- Choose Model Context Protocol when your question is “How does an AI application call tools and pull structured context, prompts, and data from an external server?” and you accept its maturity: status "Active open specification, current dated release 2026-07-28", implementation multi-implementation (Three independent registry censuses, kept separate and not averaged.
