What is measured is what a manifest declares, not what a piece of software does. This registry fetches no repository URL, no endpoint and no package index; nothing here is verified. Which value comes from which source, and by which rule it was formed, is set out in the Methodology.

| Environment variable descriptions (raw) | ACTIVITY_LOG_PATH=Append-only JSONL log of every proposal, approval, refusal and transaction, each with the agent's reasoning. · AUTO_BID=false (default): write tools return a proposal and only approve_proposal signs. true: write tools sign directly, still inside the limits. · BILLBOARD_KEYPAIR=Point this at the wallet your agent already uses. Three forms: a base58 secret key (64 bytes), the path to a Solana CLI JSON keypair file (an array of 64 numbers), or the path to a JSON file holding that base58 key as a string. Unset = read-only mode: reads and dry runs work, nothing can be signed. · BILLBOARD_SANDBOX=true or 1: rehearse against a simulated board with an ephemeral wallet generated at start-up. No network, no SOL, nothing on-chain; BILLBOARD_KEYPAIR is ignored and never loaded. false or 0 (default): the real board. No other value is accepted. · BILLBOARD_SANDBOX_SCENARIO=Which simulated board the sandbox starts from: default (a previous poster holding at 0.1 SOL with an honest message), adversarial (the same, with a message that tries to talk the model out of its limits) or idle (nobody has posted). Ignored unless BILLBOARD_SANDBOX is on. · DAILY_CAP_SOL=Total gross bids allowed per rolling 24 hours, in SOL. Defaults to MAX_BID_SOL. Refunds do not restore the allowance. · HISTORY_URL=Optional URL of a site-published history.json. Unset, unreachable or disagreeing with the chain = flip history derived on-chain. · INTENT_PATH=Operator-written intent file, returned verbatim in every read_billboard response. A missing file is not an error. · MAX_BID_SOL=Largest single bid the server will sign, in SOL. Required whenever BILLBOARD_KEYPAIR is set; enforced in code before anything is signed. · PROPOSAL_TTL_MIN=How long a proposal stays open before it expires, in whole minutes (1-1440). Default 60. Each write tool has one open proposal at a time; proposing again supersedes the older one. · RPC_URL=Solana JSON-RPC endpoint. · RPC_WS_URL=Websocket endpoint for account-change subscriptions. Defaults to RPC_URL with https replaced by wss. · STATE_PATH=Where the server remembers what this wallet last read, so a fresh process (a scheduled wake) still sees changes and outbids since the previous one. One working directory per agent. Ignored in the sandbox, which persists nothing. Source: MCP-Register · collected on 2026-09-24 · self-declared |

The image is drawn again on every request, so it always reports the current state while the pasted line stays as it is. It carries no rating and no traffic light – only the two measured figures.
