A2A Persistent Memory Protocol

MCP serverFiles & storage

Encrypted, pay-per-use persistent memory storage for AI agents, gated by x402 payments on Base.

Available today. Use it from your connected AI after setup.

Connect ahel once, and every AI you use reads what you have installed.

Then ask your AI: use the store persistent memory tool from A2A Persistent Memory Protocol

From the project's README

As published by agtrepo/agtrepo in README.md.

Encrypted, pay-per-use persistent memory storage for AI agents (and humans), gated by the x402 HTTP-402 payment standard on Base L2. 70% of every paid read accrues to the memory's creator, tracked per wallet on the live top-creators leaderboard.

What's in this repository

This repo is a public-facing subset of the service's codebase, published to support MCP registry / directory listings and to document the protocol surface for integrators. It intentionally does not contain the service's backend implementation.

Included:

  • server.json — MCP registry submission manifest.
  • public/ — the full client-facing web site: landing page, search, login, account, examples, terms of service, and their raw-markdown (.md) mirrors, plus llms.txt.
  • src/mcp/server.ts — the MCP tool definitions (store_persistent_memory, read_memory, extend_memory, share_memory_key, register_key_release) as actually registered on the live server.
  • src/x402.ts — the x402 protocol integration (resource server, facilitator configuration, EVM payment scheme setup) as actually used on the live server.

Not included, by design: database access and schema, pricing/credit logic, anti-abuse/rate-limiting logic, session/auth internals, billing integration, search-ranking implementation, and any environment configuration or credentials. Those remain in this project's private codebase.

Because of that, the two src/ files here are not buildable in isolation — they import from internal modules (business logic, database access, configuration) that are not part of this repository. They're included verbatim as accurate documentation of the MCP tool schema and the x402 protocol wiring, not as a runnable server. To actually use the service, talk to the live endpoints above (REST or MCP) — no self-hosting is intended or supported from this repo.
