AAAA-Nexus MCP sunucusu

aaaa-nexus — public entry point

This repo is the public front page for the AAAA-Nexus hosted MCP server: formally verified AI safety and compliance APIs, reachable over HTTP with no signup.

The server is live. The source is not public. That is the whole point of this repo: if you landed here from an MCP directory and every other Atomadic link was a dead end, this is the one that resolves.

Live endpoint

https://aaaa-nexus.atomadictech.workers.dev/mcp

Streamable HTTP. The server negotiates down to whatever revision the client asks for (a 2025-06-18 probe is answered with 2024-11-05). Verified live:

curl -s -X POST https://aaaa-nexus.atomadictech.workers.dev/mcp \
  -H 'content-type: application/json' \
  -H 'accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"probe","version":"1"}}}'

Then tools/list and tools/call. 44 tools are exposed. A sample:

rng_quantum, threat_score, hallucination_oracle, identity_verify, ratchet_register, authorize_action, spending_authorize, lineage_record.

The catalog also mirrors at https://aaaa-nexus.atomadictech.workers.dev/.well-known/mcp.json.

Want fewer tools? Use the starter door

https://mcp.atomadic.tech/mcp/public exposes a curated 50 of the 68 tools on the main endpoint. Same deterministic calls, same auth rules, smaller surface. GET it for a self-describing index. Start there if 68 is a lot to read.

The 30-second proof (no key, no account)

The full catalog lives at https://mcp.atomadic.tech (68 tools; a key unlocks your plan's set). Three tools need no key at all. Run this pair and you have seen the thing work:

# 1. orientation: install, connect, what you are entitled to
curl -s -X POST https://mcp.atomadic.tech \
  -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"murmuration","arguments":{}}}'

# 2. the proof: one function emitted into 12 languages from one source
curl -s -X POST https://mcp.atomadic.tech \
  -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"render_polyglot_all_pure","arguments":{"atom_name":"compute_sum_pure"}}}'

That second call returns ok: true with Python, JavaScript, TypeScript, Rust, Go, C#, Kotlin, Swift, Ruby, Lua, Elixir and Haskell, all from a single node IR.

The baked demo atoms are compute_sum_pure, keep_positive_pure, double_each_pure, count_words_pure. Call the polyglot tools with an empty argument and they answer, honestly, novel_input_not_baked — that is a boundary, not a bug: arbitrary input is what the SDK is for.

Keys are sold at https://atomadic.tech/store. A key is emailed after checkout, and X-API-Key or Authorization: Bearer ato_<key> is the whole auth story.

How calls get paid

tools/call returns an invocation contract: an HTTPS URL, a method, and a price in micro-USDC. Pay it with either

• x402 — complete payment per PAYMENT-REQUIRED on the 402 from the target route, or from /v1/payments/fee, sending an x402 PAYMENT-SIGNATURE header; or
• X-API-Key — if you already hold a key.

No account is required for x402. Pay per call.

Elsewhere

• https://atomadic.tech — main site, docs, pricing, proof page
• https://aaaa-nexus.atomadictech.workers.dev — the server itself

On missing links

Some older pages and package metadata point at GitHub repositories that are private. Those links 404 for anyone outside the account. Nothing was deleted; the repositories are closed. If you followed a broken link to get here, this README is the correction: use the live endpoint above rather than the dead source link.

Registry listing

Official MCP Registry entry: io.github.atomadictech/aaaa-nexus (latest 0.5.2, remote https://mcp.atomadic.tech/mcp/public), with repository pointing at this repo. The older io.github.atomadictech/atomadic-forge entries are marked deprecated: that endpoint returns 404 and its package is retired.
