Elucora Evidence MCP Server

Capture a public web source and return a portable, cryptographically signed evidence receipt.

Elucora is a hosted MCP server. There is nothing to install: point your client at https://elucora.com/mcp. Two of the four tools need no API key at all, so a client can verify and read receipts before anyone signs up for anything.

An agent can seal the exact page, PDF, or JSON field behind a claim, hand the receipt to someone else, and have them verify it without trusting Elucora's dashboard or its API.

Tools

ToolKey requiredWhat it does
elucora_verifyNoChecks whether a receipt is genuine and unaltered, and what source bytes it covers.
elucora_get_receiptNoReads a receipt: source, sealed passage, signature status, Bitcoin anchor state.
elucora_captureYesFetches a public HTTP(S) source, preserves the original bytes, optionally pins an exact quote or JSON Pointer, and returns a signed receipt. Consumes quota and contacts the source.
elucora_attestYesSeals a SHA-256 hash the caller already holds, for content with no URL. Proves the content existed then and has not changed since — not where it came from. Consumes quota.

The free tier is 500 receipts a month with no card.

Connecting

elucora_verify and elucora_get_receipt work with no credentials. For the two tools that contact a source or spend quota, create an API key at elucora.com/dashboard/keys, then:

{
  "mcpServers": {
    "elucora": {
      "url": "https://elucora.com/mcp",
      "headers": { "Authorization": "Bearer elu_live_..." }
    }
  }
}

The server implements stateless Streamable HTTP, protocol version 2025-11-25.

Hosts should keep a human approval step before elucora_capture: it makes a request to an external URL and consumes the account's monthly quota.

What a receipt proves

  • The captured bytes and the selected evidence match their recorded SHA-256 hashes
  • Elucora issued the receipt and it has not been altered since, by ES256 signature over RFC 8785 canonical JSON
  • The entry is in a public hash-linked log, published as signed checkpoints outside Elucora
  • When a timestamp authority is configured, an RFC 3161 token binds the entry to an independently signed time, and entry digests are submitted to OpenTimestamps for Bitcoin anchoring

A valid receipt proves integrity, issuer, and time. It does not prove that the source was telling the truth.

Limits, stated before you find them

  • Captures are HTTP, not a browser. A page that renders its content with JavaScript is captured as the shell the server sent. Filings, feeds, APIs and article pages are exactly right; single page applications and social posts are not.
  • Elucora is trusted at the moment of capture. The receipt proves what Elucora was served. Everything after that instant is verifiable without trusting Elucora at all.
  • No affidavit. Nothing here is offered as court-admissible; that is a matter for a court and its rules, not for a vendor.
  • One operator, and a young log. Both are publicly countable at elucora.com/transparency.

Verifying without Elucora

Every receipt carries jwks_url, and verification keys are published at /.well-known/jwks.json. Any ES256 implementation can check a receipt offline. The public verifier for a receipt lives at /verify/{id}.
