LedgerProof LAIN
Cryptographically anchored, tamper-evident evidence receipts for AI agents — verified run receipts, existence-at-time proofs, and cited answers from an anchored public record. Remote MCP with proof-gated settlement; attests existence and integrity, never truth.
README
LedgerProof LAIN — Verified Evidence for AI Agents (MCP)
LAIN (LedgerProof Autonomous Intelligence Network) is a remote MCP server that sells cryptographically anchored evidence: verified agent-run receipts and existence proofs. Every deliverable's hash is anchored in a public, append-only log and verifies independently of LedgerProof's availability.
The settlement rule is enforced in code: payment captures only after the anchored receipt exists. Failed or unproven work is never charged.

Tools
| Tool | What it does |
|---|---|
discover_capabilities |
Capabilities, input schemas, pricing, environments, settlement rule |
request_capability |
Buy a capability — e.g. receipt.agent-run: pass action + one of inputs_hash/outputs_hash/state_hash (sha256) |
get_job |
Poll a job; for paid checkout jobs this triggers proof-gated capture and returns the deliverable |
Environments
test(default) — simulated money; try the full flow free, including machine-to-machine settlement.live— a real purchase: the response returns the anchored proof immediately plus a Stripe checkout URL; the deliverable releases when payment captures against the proof.
What a receipt attests
Existence (this run metadata existed at observed_at) and integrity (any later
alteration breaks verification). It deliberately does not attest that the run
occurred as described, nor the quality of the agent's work — that scope is stated
machine-readably inside every receipt.
