Fidacy action firewall for AI agents. Mandate-gated payment authorization as an MCP server.
Nothing to run from here
Skavio USDC Paid Micro-APIs is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
Skavio LLC hosts 18 discoverable MCP tools. Two discovery/status tools are free. Paid x402 v2 MCP operations inspect native Circle USDC transfers (0.02 USDC), match exact recipient/amount (0.03), produce blockchain evidence PDFs (0.05) and check public DNS/TLS (0.05). MCP settlement accepts native USDC on Base or Solana using a compatible wallet with explicit spending approval. Separate HTTP x402 verify/match/evidence routes are Base-only. Company-authenticated Agent Tools use separate credentials and credits. Skavio never needs your wallet seed. Evidence PDFs are not tax invoices. Docs: https://getskavio.com/x402/docs/ . Support: support@getskavio.com.
Quickstart
Install it the way its author documents:
1. Hosted Streamable HTTP MCP: https://getskavio.com/mcp. No local install. Discovery is free; paid USDC tools need an x402 v2-capable client, your own wallet and explicit spend approval on Base or Solana. See docs for per-tool prices.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.

Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Free production availability status, including explicitly disabled processing functions. No execution or charge. Returns activation and owner-funded historical payment journal evidence separately from approved pricing and unverified realized profitability.

Release 1.1.4 · scanned 28 Oct 2026
Graded from the tools this server lists, not from its source code.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

| Term | Level | What it prices | Points |

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish Skavio USDC Paid Micro-APIs can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
