Common questions

Is Attestify OS safe?

It passed 2 of 2 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?

You need to fill in: ATTESTIFY_API_KEY, TRUST_PRIVATE_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 2 months ago, and the latest version (0.2.1) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

attestify-mcp

MCP server exposing Attestify OS agents — and Attestify Trust's no-wallet agent identity + signed evidence — as callable tools for Claude Desktop, Cursor, Windsurf, and any MCP-compatible host.

Attestify OS is infrastructure for AI agents operating in financial, compliance, and regulated workflows. Every governed run delivers: routing → governance enforcement → budget check → SLA check → execution → output verification → immutable receipt → on-chain settlement evidence.

Live base URL: https://attestifyos.com

This package is a real Model Context Protocol stdio server — your MCP host spawns it as a subprocess and talks JSON-RPC to it directly. It is not a plain HTTP client library.

Quick start

Add to your MCP host's config (e.g. Claude Desktop's claude_desktop_config.json):

"mcpServers": { "attestify": { "command": "npx", "args": ["-y", "attestify-mcp"], "env": { "ATTESTIFY_BASE_URL": "https://attestifyos.com", "ATTESTIFY_API_KEY": " ", "TRUST_AGENT_ID": " ", "TRUST_PRIVATE_KEY": " " } } } }

ATTESTIFY_API_KEY is a tenant API key issued via POST /api/keys — it's sent as the X-API-Key header on every run. Without one, runs are unauthenticated and subject to the plan/x402 limits that apply to anonymous callers.

TRUST_AGENT_ID / TRUST_PRIVATE_KEY are optional and unlock two more tools — see Attestify Trust below.

Tools

`attestify_research`

Runs a deep research query through the Attestify Research Agent (researcher-v2) via POST /api/run. Returns a structured briefing with executive summary, key findings, and caveats. Each call is metered at $0.023 USDC and logged to the Attestify evidence ledger.

Arguments:

Field	Required	Description
`query`	Yes	The research question, topic, or subject to investigate.
`url`	No	Optional source URL to include as context for the research run.
`session_id`	No	Optional session ID for conversation continuity.

Returns: a JSON blob with summary, loop_id, run_id, input_hash, output_hash, price_usdc, agent_id, receipt_url, and created_at.

`attestify_trust_submit_evidence` / `attestify_trust_verify`

Available whenever TRUST_AGENT_ID and TRUST_PRIVATE_KEY are both set. A separate concern from attestify_research above — no x402, no lanes, no spend, no wallet at any point.

attestify_trust_submit_evidence signs (Ed25519, via Node's built-in node:crypto — no extra dependency) and submits evidence that the agent completed real work, returning a signed, timestamped, publicly verifiable receipt.

Field	Required	Description
`summary`	Yes	Plain-language description of the work done. Gets signed and permanently recorded.
`schema`	No	Evidence schema version. Default `work-completion/v1`.
`action_basis`	No	`explicit` (default) or `discretionary`.

attestify_trust_verify independently re-verifies any receipt by ID — public, no API key needed, works for receipts from any agent.

Field	Required	Description
`receipt_id`	Yes	The receipt ID to verify.

Getting `TRUST_AGENT_ID` / `TRUST_PRIVATE_KEY`: run this once, outside of any MCP session — never generate a fresh identity per session, it would both break the agent's own verified-active streak and add noise to Attestify's public census instead of a real, citable number:

npx attestify trust-init --name "My MCP Agent"

This registers a free Trust agent, generates its Ed25519 signing key locally, and prints the two values to set in your MCP host's config. The private key never leaves your machine except as a signature.

Enterprise self-serve

Issue a tenant key, set a budget, attach policies — every subsequent run through this server is auto-governed:

1. POST /api/keys      → issue tenant API key

POST /api/budgets → set USDC spend ceiling
POST /api/policies → attach governance rules
(this MCP server) → every run auto-enforced
