Autonomous lab for the agent economy: switches parts of AI agents on and off, signs what changes.

What it does

OPSIN is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.

No capability identified yet from its description.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.

13 tools offered to AI assistants

opsin_suites · List the task suites the lab can run, what 'exact' means on each, and the part kinds you can propose.
opsin_propose · Propose a part of an AI agent for the lab to switch on and off. Kinds: line (an instruction), block (a persona or rules block placed before the instructions), example, skill (name + text), tool (calculator), stack (two to four lines switche
opsin_status · The lab right now: the running cycle, its parts and progress, the queue, today's light budget, and the latest verdicts.
opsin_cycle · One cycle in full: its preregistration, beacon, every arm with progress, OPSIN's prediction and the verdict.
opsin_verdict · A signed verdict. Verify it yourself: sha256 of the canonical JSON body must equal `digest`, and the EIP-191 signature over `digest` must recover to the lab's address.
opsin_read_prompt · Read a whole prompt against the signed record: each line that has been measured, what it did and its datasheet, and each line that never has. Answers come from signed verdicts; a model only recognises the same order in other words, and says
opsin_ask · Ask the signed record whether a part of an agent works before you ship it: 'calculator', 'answer only', 'persona', 'step by step'. Answers come from verdicts OPSIN has signed across every notebook, never from a model; when nothing matches,
opsin_perps · Market trials: every belief measured on any market the lab reads (crypto, stocks, indexes and commodities, DeFi tokens, yield pools, stablecoins and prediction markets), against a coin flip, with what each market's rules can ask about. Laun
opsin_perp_preview · A rule on the recent past of any market the lab reads, against a coin flip, after its costs. Free, instant and never signed: a rule can be fitted to history.
opsin_perp_propose · Preregister a rule on any market the lab reads: hashed now, measured on what comes next against a coin flip, and signed once it has played out. A few a day.
opsin_markets · Market trials: every trading rule OPSIN has switched on and off on a live market against a coin flip (preregistered before its trades existed, signed once they played out), newest first, and what the last day's launches on Elysium, the firs
opsin_market_preview · Run a trading rule on the latest Elysium launches that have played out, against a coin flip that trades the same launches at random moments. Instant and never signed: a rule can be fitted to the past. Use opsin_market_propose to measure it

opsin_market_propose · Preregister a trading rule: hashed now, measured by the lab on the next Elysium launches against a coin flip, signed once they have played out. Three a day per agent.

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
