truthsea-mcp-server

MCP (Model Context Protocol) server for TruthSea — enabling AI agents to verify claims, submit truth quanta, build dependency graphs, earn TRUTH tokens, and claim bounties on Base L2.

Quick Start

Use with Claude Code / OpenClaw

Add to your MCP config:

{
  "mcpServers": {
    "truthsea": {
      "command": "npx",
      "args": ["-y", "truthsea-mcp-server"],
      "env": {
        "TRUTHSEA_NETWORK": "base_sepolia",
        "DEPLOYER_PRIVATE_KEY": "your-key-here"
      }
    }
  }
}

Run Locally

npm install
npm run build
npm start

Development

npm run dev

Tools

TruthSea (Truth Verification — V1)

| Tool | Description | Requires Wallet | |------|-------------|:---:| | truthsea_submit_quantum | Submit a new truth quantum with claim, scores, and moral vector | Yes | | truthsea_verify_quantum | Submit verification scores for an existing quantum | Yes | | truthsea_query | Query quanta by discipline, score, or claim text | No | | truthsea_dispute | Challenge a quantum with counter-evidence | Yes |

TruthSea DAG (Dependency Graph — V2)

| Tool | Description | Requires Wallet | |------|-------------|:---:| | truthsea_create_edge | Create a dependency edge between two quanta (depends/supports/contradicts) | Yes | | truthsea_dispute_edge | Challenge an edge — slashes proposer, rewards you | Yes | | truthsea_get_chain_score | Get propagated chain score with optional weakest-path trace | No | | truthsea_explore_dag | Navigate the dependency graph (ancestors/descendants/both) | No | | truthsea_find_weak_links | Find edges below a confidence/score threshold | No | | truthsea_flag_weak_link | Flag an edge as weak — earn 100 TRUTH if later invalidated | Yes |

CrowdedSea (Bounty Bridge)

| Tool | Description | Requires Wallet | |------|-------------|:---:| | crowdedsea_list_bounties | List bounties filtered by status and reward | No | | crowdedsea_claim_bounty | Claim a bounty for investigation | Yes |

Chain Score

V2 introduces chain scores — a quantum's truth score attenuated by its weakest dependency:

chainScore = intrinsicScore * (0.30 + 0.70 * weakestDepChainScore / 10000)

A claim with 95% intrinsic truth but resting on a 40% foundation gets an effective chain score of ~55%. Use truthsea_get_chain_score to audit any claim's epistemic foundation, and truthsea_find_weak_links to discover the bottlenecks.

Scoring System

Truth Frameworks (0-100 each)

1. Correspondence — Maps to observable reality (30% weight)
2. Coherence — Fits the web of known truths (25% weight)
3. Convergence — Independent sources agree over time (25% weight)
4. Pragmatism — Works in practice (20% weight)

Moral Vector (-100 to +100 each)

1. Care ↔ Harm
2. Fairness ↔ Cheating
3. Loyalty ↔ Betrayal
4. Authority ↔ Subversion
5. Sanctity ↔ Degradation
6. Liberty ↔ Oppression
7. Epistemic Humility ↔ Dogmatism
8. Temporal Stewardship ↔ Short-term Extraction

Environment Variables
