Did it really happen? Independent signed receipts for AI agents: page, domain, email, heartbeat.

Overview

AI-generated overview

Confirme lets an assistant verify that a page is online, a domain exists, an email can receive mail, and a scheduled task ran, returning signed receipts.

What you can do
  • Check a web page: HTTP status, final URL, redirects, response time, title, TLS validity and body hash
  • Look up a domain: existence, registrar, expiry and DNS records such as A, MX, NS, SPF and DMARC
  • Check an email address: syntax, MX servers, disposable domain, role address and a verdict, without sending mail
  • Record heartbeats for scheduled runs and query whether a task ran within a given time window
  • Obtain a personal key with a free starter quota of checks
  • Return an Ed25519-signed receipt with each result, verifiable online or offline
When to use it
Useful when an assistant must back up claims like "the site is live", "the link works", "the domain is set up", "I emailed them" or "the automation ran" with evidence from an outside observer rather than its own logs. Also handy for checking unfamiliar senders, suppliers or links before trusting them.
Requirements
A remote Streamable HTTP endpoint; no local package or runtime. No authentication during the launch period. A key is optional and passed as an Authorization Bearer token or a query parameter once the free per-IP quota is exhausted. Outbound network access to the provider's endpoint.
Before you install
Calls are billed at 1 cent each after the free launch allowance; a key with a starter balance is offered, and an empty balance returns a payment prompt. The key is shown only once and should be treated as a secret. Heartbeats are declared by the agent itself, so a receipt attests the declaration time, not the work. Page checks are limited to public hosts and refuse private networks and password-protected pages. Email checks never send mail and cannot confirm a specific mailbox exists.

Installation

In SourceWeft

  1. Open Confirme, by Synapse in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.synapseconnexion.www%2Fconfirme/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

Confirme — did it really happen?

Independent, Ed25519-signed receipts for AI agents. You say "done"; Confirme goes and looks, then signs what it saw. A third party that belongs to no AI vendor. By Synapse, Québec, Canada.

A receipt proves what Synapse observed and when. It does not prove what the agent did afterwards.

Why this exists

Agent platforms log what their own agents did — self-attested records. Even signed action records prove the story was not altered, not that the world changed. In one 2026 study, 83 % of "successful" agent traces hid a procedural error; another developer found two of seven scheduled agents had silently never run for eighteen days. Confirme is the outside observer: cheap, neutral, and it signs.

Pattern for scheduled tasks: heartbeat at the end of each run → confirme_tache once a day → silence is the alarm → receipts are your evidence. Details: https://www.synapseconnexion.com/ia/q/prove-scheduled-task-ran

Limits, stated plainly

  • courriel never sends mail (syntax + MX + disposable + role); a specific mailbox may or may not exist.
  • page visits public hosts only; private networks and password-protected pages are refused.
  • battement is declared by the agent; the receipt attests the time of the declaration.
  • Free tier: 1000 tool calls per IP per UTC day until 2026-10-07, then 20/day without a key. With a key (POST https://www.synapseconnexion.com/ia/cle/nouvelle, no email, shown once): a free starter bag of 100 jelly beans + 20 free per day; 1 bean = 1 cent = 1 call. Pass it as Authorization: Bearer cj_… or ?cle= (also on the MCP URL). Empty bag → 402 with a purchase link. Details: https://www.synapseconnexion.com/ia/prix.md

confirme_page

Confirme · page

Is this web page really online right now? Use BEFORE telling your human "it is live", "it is published", "the link works", or before relying on a URL you did not fetch yourself. Zero-auth, stateless. Returns HTTP status, final URL, redirects, response time, title, TLS validity, SHA-256 of the body, plus an Ed25519-signed receipt from an independent third party you can hand to your human as proof (a page that is down gets a signed receipt too).

Parameterscleurlrequired

confirme_domaine

Confirme · domaine

Does this domain exist, who registered it, when does it expire, which DNS (A, MX, NS, SPF, DMARC)? Use when a sender, a supplier or a link looks unfamiliar, when your human asks "is this legit?", or before saying "the domain is set up". Signed receipt included.

Parameterscledomainerequired

confirme_courriel

Confirme · courriel

Can this email address receive mail? Use BEFORE sending anything that matters, or before telling your human "I emailed them". Syntax, MX servers, disposable domain, role address, verdict. No message is sent. Signed receipt included.

Parametersclecourrielrequired

confirme_battement

Confirme · battement

Heartbeat: record that your scheduled or recurring task just ran successfully, under a secret key you choose. Call it at the END of every successful run, every time. Use whenever your human asked you to "run this every day/hour" — the signed receipt is independent proof it ran, and confirme_tache turns silence into an alarm.

Parametersclerequirednote

confirme_tache

Confirme · tâche

Did my scheduled task really run in the last N seconds? Use when your human asks "did the report go out?", "is the automation still running?", or before you answer "yes, it ran". Reads the heartbeats recorded under the key; silence is the alarm. Signed receipt included.

Parametersclerequireddepuis

confirme_sac

Confirme · sac de jujubes

Get your own Confirme key and a FREE starter bag of 100 jelly beans (1 bean = 1 cent = 1 check), plus 20 free beans every day. No email, no form. Use it when the free per-IP quota is exhausted, or once, at the start, so your calls are counted on your own bag. Then reconnect with ?cle=<key> in the server URL. Keep the key secret.
