delboy-mcp 1.0.0

DELBOY companion-MCP — neutral provenance/attestation layer for agentic finance. Witness only: signs, hash-chains, timestamps. Never holds funds, routes orders, recommends trades, or executes.

Agent Attestation MCP (codename: DELBOY)

Neutral, model-agnostic, rail-agnostic provenance & attestation layer for agentic finance and agentic commerce. It witnesses what an AI agent did on a human's behalf — signs (Ed25519), hash-chains, and timestamps each consequential action into one regulator-readable evidence envelope (delboy/v1.0).

It never holds funds, routes orders, recommends trades, custodies assets, or executes. Witness only — it touches the evidence of a transaction, never the transaction.

Maps to EU AI Act · UK FCA · US SEC/FINRA · EU MiCA · Singapore MAS.

Companion-MCP pattern

The agent connects to both the upstream MCP (e.g. a broker) and this server. Around any consequential call it calls attest_pending_action → performs the upstream call itself → attest_completed_action. On guardrail failure, attest_terminal. verify_chain checks link integrity + every signature.

Install

pip install -e .
delboy-mcp          # starts the FastMCP server (stdio)

Env: DELBOY_LEDGER, DELBOY_KEY, DELBOY_KEY_ID.
