Common questions
Is Atomadic starter MCP (50 tools) safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.5.2) reached the registry 10 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Spec Driven Development, Remote Desktop Commander, dotnet-mcp

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/mcpStreamable 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 tocurl -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_ 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-REQUIREDon the402from the target route, or from/v1/payments/fee, sending anx402 PAYMENT-SIGNATUREheader; 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.
