ArkForge MCP server

by ark-forge

Your AI can make web calls that come back with a signed, timestamped proof of what was sent and received.

Flow diagram: you ask your AI “Call our payments API and give me proof of it”, the ArkForge MCP server connects it to A web service, and you get back the reply plus a signed proof.

ArkForge is a helper that sits between your AI and the websites or services it calls. Every call it makes gets a signed receipt, so you can prove later what was sent, what came back, and exactly when. It is handy if you need a record of important calls, for example for audits, finance work, or anything where someone might later say "that never happened".

What is an MCP server? The 30-second version

On its own, your AI can only chat with you. An MCP server is a small helper program that gives your AI a new skill or a connection to another service. This one connects your AI to ArkForge, a service that makes web calls on your behalf and hands back a signed proof of each one. So when you ask your AI to call something, it goes through ArkForge, and you get both the answer and a receipt you can check later.

What this MCP server does

You ask your AI to call a web address, for example a payment service or a data provider. Your AI passes that request to this helper, which sends it through ArkForge. ArkForge makes the call, records exactly what went out and what came back, then signs the whole thing with its own key and stamps the time. You get the reply from the service plus a link where anyone can check the proof, without needing to ask ArkForge again.

What you can do with it

  • Make a web call and get a signed proof of it
  • Look up a proof you made earlier by its ID
  • Get a plain-language summary of what a proof actually certifies
  • Check how many proofs you have left this month
  • Keep an audit trail of calls your AI makes to outside services

Try asking your AI

  • “Call https://api.example.com/status and give me a proof of the response”
  • “Certify this call to our payments API and tell me the verification link”
  • “Show me the proof with ID prf_20260310_143022_a1b2c3”
  • “Explain in plain words what this proof certifies”
  • “How many proofs do I have left this month?”

What it gives back to you

You get back the reply from the service you called, plus a proof ID, a public link where the proof can be checked, a timestamp, and a signature. You can also ask for a plain-language summary of a proof, which is useful when you need to explain it to someone else. The proof itself lists the exact request and response, the domain that was called, and the log entry that anchors it.

Before you start

What you need

  • A free ArkForge API key from arkforge.tech (it gives you 500 proofs a month at no cost)
  • The uvx tool installed on your computer, which is how the helper is started
  • The Claude desktop app or another AI app that supports MCP servers

Good to know

Each call you certify uses up one of your monthly proofs, and the proof is permanent and publicly checkable, so do not send anything through it that should stay private.

Install it with your AI

Add ArkForge MCP server to your AI, no technical skills needed

You don't install anything by hand. You copy one prompt, paste it into an AI that can work on your computer, and it checks, installs and connects the server for you, asking you when it needs something.

Sign in to get the install prompt

Members get a ready-made prompt that lets the Claude desktop app check ArkForge MCP server, install it and connect it for them, step by step. You don't need any technical skills: you copy, paste and answer a few questions. Your connected AI can also find and install any of the 4,066 MCP servers here for you.

Who it's for

People who need a record of important web calls, such as auditors, finance and compliance staff, and anyone building automations where proof of what happened matters.
