Orphograph MCP server

A single-file Model Context Protocol server that lets a Claude / Claude Code / Cursor / any-MCP-host instance anchor files to the Bitcoin chain via Orphograph without the file ever leaving the user's machine.

mcp-name: io.github.Orphograph/orphograph

License: MIT
Dependencies: Python ≥ 3.9 standard library only. Also on PyPI as orphograph-mcp 0.1.1.
Lines of code: ~310, single file.
Protocol: MCP 2024-11-05 over stdio.

Install

Save the script anywhere:

curl -sSL https://orphograph.com/mcp/orphograph_mcp.py -o ~/bin/orphograph_mcp.py

Then register it with your MCP host.

Claude Desktop (`~/Library/Application Support/Claude/claude_desktop_config.json`)

"mcpServers": { "orphograph": { "command": "python3", "args": ["/Users/YOU/bin/orphograph_mcp.py"], "env": { "ORPHO_API_KEY": "" } } } }

Claude Code

claude mcp add orphograph python3 /Users/YOU/bin/orphograph_mcp.py

Or edit ~/.claude/settings.json and add the same mcpServers block.

Cursor (`~/.cursor/mcp.json`)

"mcpServers": { "orphograph": { "command": "python3", "args": ["/Users/YOU/bin/orphograph_mcp.py"], "env": { "ORPHO_API_KEY": "" } } } }

Tools exposed

Tool	Purpose	Auth
`orphograph_anchor_file(path)`	Hash a local file and register the fingerprint on Bitcoin.	Optional API key
`orphograph_anchor_folder(path)`	Hash a whole folder into an RFC-6962 Merkle tree and anchor one root covering every file.	Optional API key
`orphograph_anchor_output(text, …)`	Hash generated output (an agent result, a transcript) in-process and anchor it. Accepts an optional `zk_proof`. The fingerprint is public on the receipt, so for short or guessable output pass `salt: true`: it anchors SHA-256(salt + text), returns `salt_hex` (never transmitted) and needs it to verify. Every anchor reply says `bitcoin_status`: `pending` until the calendars commit to a Bitcoin block (usually hours), then `confirmed`.	Optional API key
`orphograph_verify_receipt(receipt_id)`	Look up what the office recorded for a receipt. A lookup — it does NOT consult the chain; run `ots verify` for that.	None
`orphograph_verify_lineage(receipt_id)`	Walk an edit-lineage chain back through its committed parents.	None
`orphograph_list_vault(limit?)`	List the subscriber's receipts.	API key required
`orphograph_anchor_run(steps, label?)`	Anchor every step of an agent run under one receipt; each step provable alone.	None
`orphograph_verify_output(receipt_id, text \	sha256_hex, salt_hex?)`	Check whether a receipt covers an exact output, trusting only the anchored hash. Pass `salt_hex` for an output anchored with a salt.	None

Privacy contract

The file body never leaves the device.
The script computes SHA-256 + SHA-512 in-process and transmits only those fingerprints to https://orphograph.com/api/anchor.
The script makes no network call until a tool is explicitly invoked by the host.
File reads stream in 1 MB chunks; large files do not load into memory.

Configuration

Environment variable	Purpose
`ORPHO_API_KEY`	Optional. Issued from orphograph.com/account.html. Without it, the install is rate-limited to the free tier (3 anchors per 24 hours).
`ORPHO_BASE_URL`	Optional. Defaults to `https://orphograph.com`. Override for testing or self-hosted instances.
`ORPHO_X402_PAYER_KEY_FILE`	Optional (0.1.6). Path to a `chmod 600` file holding the hex private key of a dedicated Base wallet with USDC. With the daily cap below, anchors past the free tier are paid with x402. The key never leaves the machine.
`ORPHO_X402_DAILY_CAP_CENTS`	Optional (0.1.6). The most the server may pay in one UTC day, in cents. Paying stays off unless this and the key file are both set.
`ORPHO_X402_MAX_CENTS_PER_CALL`	Optional (0.1.6). The most one anchor may cost, in cents. Default 5.

With paying on, the server pins the USDC contract, its signing domain and the chain (Base); a 402 asking for anything else, or for more than either cap, is declined and nothing is signed. Spending is recorded in ~/.orphograph/x402_spend.json. A paid result carries x402_payment with the amount and the on-chain transaction.

Tiers and limits

Tier	Cap	Price
Free	3 anchors / 24h	$0
Writer Pack	25 anchors, never expires	$5 one-time
Pack of Two Hundred	200 anchors, never expires	$20 one-time
Standing Order	Unrestricted anchoring	$9 / month
Agents (x402)	Past the free tier, per anchor	1 cent in USDC on Base

Verification

The MCP server only issues calls. Every receipt it produces can be checked without this office, in two independent steps:

Structure — the open-source verifier at github.com/Orphograph/Orphograph re-derives the hashes and checks the receipt offline. It makes no network calls of its own.
Chain — the OpenTimestamps client (ots verify) confirms the commitment actually landed in a Bitcoin block. The bundled verifier will invoke it for you when passed --ots.

Only step 2 consults Bitcoin.
