OPSIN MCP

An autonomous lab for the agent economy that measures the impact of AI agent parts by switching them on and off, publishing signed verdicts (EXCITES, INERT, INHIBITS, UNRESOLVED) with statistical intervals and costs. It supports agent evaluation, market trials, and preregistered scientific testing of AI components.

opsin_suites

Advertised by the server during the last successful anonymous check.

List the task suites the lab can run, what 'exact' means on each, and the part kinds you can propose.

opsin_propose

Advertised by the server during the last successful anonymous check.

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 switched on together), setting (thinking on/off, effort low/medium/high), route (claude-sonnet-5-5 or claude-opus-5-5). Returns the proposal id; the verdict arrives when its cycle publishes.

The lab right now: the running cycle, its parts and progress, the queue, today's light budget, and the latest verdicts.

{
  "type": "object",

opsin_cycle

Advertised by the server during the last successful anonymous check.

One cycle in full: its preregistration, beacon, every arm with progress, OPSIN's prediction and the verdict.

}

opsin_verdict

Advertised by the server during the last successful anonymous check.

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

Advertised by the server during the last successful anonymous check.

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 so on the match. Nothing pasted is stored.

  }
}

opsin_built_agents

Advertised by the server during the last successful anonymous check.

The best agents OPSIN has built from parts that held up: on each setting, the parts in the exact words they run with, the exact request the lab measured (put your task in its user turn), the points it adds against the unchanged agent, and the signed verdict behind every step. Narrow it with suite and thinking.

    }
  }
}

opsin_ask

Advertised by the server during the last successful anonymous check.

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, it says so and offers opsin_propose.

  }
}

opsin_perps

Advertised by the server during the last successful anonymous check.

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. Launches on Elysium are in opsin_markets.

  "type": "object",

opsin_perp_preview

Advertised by the server during the last successful anonymous check.

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_markets

Advertised by the server during the last successful anonymous check.

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 first market the lab reads, did in their first hour.

opsin_market_preview

Advertised by the server during the last successful anonymous check.

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 on launches that do not exist yet.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http opsin-mcp https://opsinlab.io/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add opsin-mcp --url https://opsinlab.io/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable opsin-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "opsin-mcp": {
      "url": "https://opsinlab.io/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).

Cline configuration

{
  "mcpServers": {
    "opsin-mcp": {
      "type": "streamableHttp",
      "url": "https://opsinlab.io/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start opsin-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "opsin-mcp": {
      "type": "http",
      "url": "https://opsinlab.io/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http opsin-mcp https://opsinlab.io/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.

Claude Desktop configuration

https://opsinlab.io/mcp

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "opsin-mcp": {
      "serverUrl": "https://opsinlab.io/mcp"
    }
  }
}
