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
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:
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:
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.

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.
