Which integrations are available for this server?

Provides cryptographic certification for GitHub webhook events, creating a tamper-evident record of received payloads and timestamps. Allows LangChain developers to generate independent, verifiable proofs for all external API calls within their AI agent workflows. Certifies actions within n8n automation workflows by routing HTTP calls through a proxy that signs and timestamps the transaction. Generates independent cryptographic proofs for Stripe webhook events to verify the exact payload and timing of incoming notifications. Enables the certification of HTTP actions in Zapier workflows, producing publicly auditable logs of automated transactions.

ArkForge Trust Layer — MCP Server

Third-party certifying proxy — get an independent cryptographic proof for any HTTP call.

Works with AI agents, webhooks, microservices, or any HTTP client. The proof is signed by ArkForge (independent third party) — not by the caller.

Why this matters

When a system makes an HTTP call, there is no independent record of what was sent, what was received, or when it happened. Either party could deny or alter the transaction.

ArkForge fixes this by acting as a certifying proxy: the caller routes its request through ArkForge, which signs the full request+response bundle with an Ed25519 key, timestamps it via RFC 3161, and anchors it in Sigstore Rekor — an immutable, publicly auditable log.

The resulting proof is permanently verifiable at a public URL, by anyone, without contacting ArkForge.

This is the difference between a self-signed certificate and a CA-issued one. Other tools produce proofs signed by the caller itself. ArkForge produces proofs signed by an independent third party.

Use cases

AI agents — audit trail for every external API call (Claude, GPT, Mistral, LangChain, AutoGen)
Webhooks — prove a Stripe or GitHub event was received with this exact payload
Microservices — tamper-evident log between internal services (compliance, fintech)
Data providers — prove an external API returned this value at this timestamp
Automations — certify an action in an n8n or Zapier workflow

Tools

`certify_call`

Route an HTTP call through ArkForge and get a cryptographic proof of the transaction.

target          URL of the upstream API to call
payload         JSON body (optional)
method          "POST" or "GET" (default: "POST")
description     Human-readable description included in the proof
agent_identity  Identifier for the calling system (optional)

Returns proof_id, verification_url, upstream_response, chain_hash, timestamp, and Ed25519 signature.

Use this instead of calling the API directly when you need an auditable record.

Example response:

{
  "proof_id": "prf_20260310_143022_a1b2c3",
  "verification_url": "https://trust.arkforge.tech/v1/proof/prf_20260310_143022_a1b2c3",
  "upstream_response": { "status": "ok" },
  "chain_hash": "e3b0c44298fc1c149afb...",
  "timestamp": "2026-03-10T14:30:22.481Z",
  "timestamp_authority": "verified",
  "rekor_log_id": "https://rekor.sigstore.dev/api/v1/log/entries/...",
  "seller": "api.example.com",
  "signature": "MCowBQYDK2VwAyEA..."
}

`get_proof`

Retrieve the full proof bundle for a given proof_id.

`verify_proof`

Get a human-readable summary of what a proof certifies — useful for explaining to a user or auditor what was independently verified.

`get_usage`

REST API

The MCP server is one integration path. The same API works from any language or framework:

curl -X POST https://trust.arkforge.tech/v1/proxy \
  -H "X-Api-Key: your_key" \
  -H "Content-Type: application/json" \
  -d '{"target": "https://api.example.com/action", "payload": {"data": "value"}}'
