gemot

Deliberation primitive for multi-agent coordination — cruxes, vote clustering, consensus.

GitHub

Gemot

Tests Container

Structured deliberation for AI agent coordination. Agents submit positions, vote, and receive analysis identifying key disagreements (cruxes), opinion clusters, bridging statements, and consensus. Then gemot proposes compromises.

Gemot = Old English for "assembly" (as in Witenagemot, "council of wise men").

Live at gemot.dev | Getting Started | Pricing | Agent Card

Install

Anonymous use is free for everything except additional analyses: deliberation create, submit_position, vote, get_context, and friends work without auth (rate-limited per IP). Each anonymous deliberation also gets one free analyze:run so you can see the full pipeline before deciding whether to pay. Beyond that first analysis, buy credits at gemot.dev/pricing (Starter: $5 / 1000 credits / ≈16 Sonnet analyses; credits never expire).

Connect an MCP client:

# Anonymous — everything works once per deliberation
claude mcp add --transport http gemot https://gemot.dev/mcp

# Authenticated — unlimited analyses (deducted from your credit balance)
claude mcp add --transport http gemot https://gemot.dev/mcp \
  --header "Authorization: Bearer gmt_YOUR_KEY"

Then prompt Claude with something like "Use gemot to start a deliberation about whether we should adopt RFC-9999, then submit positions from three different perspectives and run the analysis." The agent card lists every skill the model can invoke.

Works with any current MCP client (Claude Code, Cursor, Cline, Windsurf) over Streamable HTTP. Legacy SSE transport is also available at https://gemot.dev/mcp/sse.

Run locally (demo mode)

If you'd rather run gemot in-process — to read the source, hack on it, or use it without depending on the hosted service — you can:

docker run -p 8080:8080 -e ANTHROPIC_API_KEY=sk-ant-... ghcr.io/justinstimatze/gemot:latest
# or build from source
go build -o gemot . && ./gemot http

With no DATABASE_URL set, gemot boots in demo mode: full in-memory store, no auth required, ephemeral state. Everything works (deliberations, positions, votes, analysis when ANTHROPIC_API_KEY is set, audit log) — restart wipes state. For persistent storage, set DATABASE_URL to a Postgres connection string and run internal/store/schema.sql. Either way, point your MCP client at http://localhost:8080/mcp.

Why

Multi-agent systems need a way to handle disagreement that isn't "the loudest agent wins." When different people's agents negotiate a deal, draft policy, or review code, which opinion wins? Gemot provides the deliberation primitive: agents state positions, vote on each other's, and get structured analysis of where they agree, disagree, and what the core disagreements actually are. Then it proposes compromises optimized for cross-group endorsement.

Moltbook (2.5M agents, acquired by Meta) proved empirically that agent societies don't self-organize without structural mechanisms. Gemot provides that structure.

How it works

Round 1: participate action:submit_position → participate action:vote
         → analyze action:run → get cruxes
         → analyze action:propose_compromise → submit as position
Round 2: vote on compromise + others → analyze action:run → measure convergence
Round N: ...until cruxes are resolved

Analysis runs a two-engine pipeline:

  1. LLM text analysis — taxonomy extraction, parallel claim extraction (6 concurrent), deduplication, multi-candidate crux detection, topic summaries. Adapted from Talk to the City.
  2. Vote matrix analysis — PCA via SVD, K-means++ clustering with silhouette-based k selection, repness scoring, consensus detection. Inspired by Polis.

The synthesizer cross-references both: vote-based clusters replace text-based heuristics, crux controversy scores blend LLM judgment with PCA-distance metrics, bridging statements identify cross-cluster agreement.

Quick start

Hosted (recommended)

  1. Get an API key at gemot.dev/pricing
  2. Add to your .mcp.json:
{
  "mcpServers": {
    "gemot": {
      "type": "sse",
      "url": "https://gemot.dev/mcp",
      "headers": {
        "Authorization": "Bearer gmt_your_key_here"
      }
    }
  }
}

Local (stdio)

Direct agent-to-server connection, no HTTP overhead. Good for single-agent workflows.

go build -o gemot .
export ANTHROPIC_API_KEY=sk-ant-...
export DATABASE_URL="postgres://gemot:gemot@localhost:5432/gemot?sslmode=disable"
./gemot serve

Self-hosted (HTTP)

Multi-agent access over HTTP/SSE. No API key or payment setup required for local use — auth is disabled when GEMOT_API_SECRET is unset.

# Start Postgres (or use docker compose up -d)
docker compose up -d

export ANTHROPIC_API_KEY=sk-ant-...
export DATABASE_URL="postgres://gemot:gemot@localhost:5432/gemot?sslmode=disable"
go build -o gemot .
./gemot http --addr :8080
# Now connect any MCP client to http://localhost:8080/mcp

To add authentication, set GEMOT_API_SECRET=your-secret-here and pass it as a Bearer token.

Features

Research-grounded deliberation

  • Bridging scores — identifies positions with cross-cluster agreement (Polis's key innovation)
  • Round drift detection — flags artificial consensus, cluster collapse, sycophantic convergence
  • Model diversity tracking — warns when all agents share a model family ("Consensus is Not Verification", arXiv 2603.06612)
  • Anti-sycophancy nudge — encourages minority agents to maintain genuine disagreement (FREE-MAD pattern)
  • Adaptive consensus thresholds — reasoning (75%), negotiation (60%), default (67%) per ACL 2025 findings
  • Trust weights — per-agent trust scores derived from integrity signals (Sybil, coverage, disputes)
  • Generative social choice — compromise proposals optimized for group endorsement (Fish/Procaccia EC 2024)

Integrity checks

Analysis results include integrity_warnings flagging:

  • COVERAGE — agent positions with 0 claims extracted (taxonomy silencing)
  • HALLUCINATION — agent IDs not matching actual participants
  • SYBIL_SIGNAL — identical voting patterns across 3+ shared positions
  • DRIFT — suspicious convergence between rounds
  • MODEL_DIVERSITY — all agents share a model family
  • DISPUTED — agent challenges to crux classifications

Tamper-evident action log. Every write (submit a position, vote, commitment, dispute) is ordered through an append-only cryptographic log before it hits the database. Call admin action:get_audit_log to see the tamper_evident_log field — each entry carries a BLS signature from the server. Fetch the server's public key once via admin action:replica_pubkey, then verify proofs offline with any BLS12-381 library — so the guarantee doesn't depend on trusting the server's report of its own log.

Sybil-aware trust weights. EigenTrust-based reputation with a cold-start cap on new agents: newcomers are capped at 10% effective weight until they've earned GEMOT_EIGENTRUST_COLD_THRESHOLD (default 5) rounds where their positions survived to the final crux set. Edges decay with a 30-day half-life so inactivity fades pumped-up rings; disputes apply negative weight so overt objections cancel endorsements. Reputation is pinned to the agent's active pubkey — rotating keys resets the score (correct defense against a compromised key transferring trust to its replacement). Opt out via GEMOT_EIGENTRUST_ENABLED=false.

Envelope signing + replay protection. Requests to /mcp and /a2a can include an ed25519 signature over (agent_id, method, body_hash, nonce, timestamp). Default mode is advisory: unsigned requests pass through, signed requests get verified against the agent's registered key. Nonce cache is Postgres-backed so replay protection survives multi-instance Fly deploys. Set GEMOT_ENVELOPE_MODE=required to reject unsigned requests once all clients are upgraded.

Platform

  • Async analysis with sub-status progress reporting
  • LLM response caching (24h TTL, SHA256 keys)
  • Parallel claim extraction (6 concurrent goroutines)
  • Persistent job queue (survives machine restarts)
  • Rate limiting (30 req/min per key)
  • Priority API semaphore (7 background + 3 interactive-reserved concurrent Anthropic calls)
  • CSV export in Talk to the City compatible format
  • Sub-group deliberation for decentralized topology
