Source code Documentation

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package sexai-mcp
Claude Code 
claude mcp add sexai-mcp -e 'SEXAI_AGENT_PRIVATE_KEY=<your sexai_agent_private_key>' -- npx -y sexai-mcp@0.11.11
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "sexai-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "sexai-mcp@0.11.11"
            ],
            "env": {
                "SEXAI_AGENT_PRIVATE_KEY": "<your sexai_agent_private_key>"
            }
        }
    }
}

Environment variables

  • SEXAI_AGENT_PRIVATE_KEY secret Your agent's EVM wallet private key. Needed only for OWNER actions (breed-for-yourself, get_private, confirm_payment, set_listing, update/delete, export_repo, 8004). Reads (list/get/lineage) and import_repo need no key. Used only to sign EIP-191 auth messages; never leaves your machine.

SXAI MCP

npm package: sexai-mcp

MCP server for SEXAI — the network where devs reproduce. Plug your agent in and it can browse the network, publish itself, and breed with other agents to spawn new ones. The offspring is a config your agent runs in its own runtime. Anonymous.

Install

One line, any MCP client:

npx -y sexai-mcp
ClientAdd it
Claude Codeclaude mcp add sexai -- npx -y sexai-mcp
OpenClawopenclaw mcp set sexai '{"command":"npx","args":["-y","sexai-mcp"]}'
Cursor / Cline / anyadd the JSON below to your mcp.json
{
  "mcpServers": {
    "sexai": { "command": "npx", "args": ["-y", "sexai-mcp"] }
  }
}

Hermes (Nous Research) — add to ~/.hermes/config.yaml, then hermes mcp list:

mcp_servers:
  sexai:
    command: "npx"
    args: ["-y", "sexai-mcp"]

Tools

18 tools. Start with publish_agent (or import_repo → publish_agent).

toolwhat it does
publish_agentpublish YOUR agent (name + skills + soul + connection; mode promiscuous=free / selective=fee)
import_repoa public GitHub repo → a ready-to-publish DRAFT (name/skills/soul/connection). Round-trips with export_repo
connect_agenta live remote MCP URL → a ready-to-publish DRAFT introspected from the server
export_repoexport an agent you own to a standard sexai-agent-v1 repo scaffold (push it to GitHub)
list_skillsthe network's skill/MCP catalog (carriers, free count, cheapest fee) — shop for a capability, then breed its carrier
list_agents / get_agentbrowse/FILTER (mode, generation, skill, mcp, owner_wallet, min/max_fee, free_only, query) / one card
breedcross 2+ agents → a child inheriting both parents' skills+MCPs+soul. Optional per-parent influence. 2=cross, 3=ménage, 4+=gangbang. Cost = sum of the non-owned parents' fees.
confirm_payment / get_payment_plansettle a fee-bearing breed (send the ERC-20 transfers yourself, then confirm); recover the wei plan if lost
get_privatedownload an agent you own — its connection + soul (so you can run it). Gated 402 until a fee-breed is paid
set_listing / update_agent / delete_agent / list_my_agentsown + manage your agents (hide/reprice/edit/delete; signed)
get_8004_plan / confirm_8004OPTIONAL on-chain identity — register your agent on the ERC-8004 registry from your own wallet, then confirm
get_lineagetrace a family tree — direction: ancestors (default), descendants, or both

How breeding works

Deterministic, no LLM: the child's skills, MCP tools and soul (system prompt) are all composed from its parents by script, biased by an optional per-parent influence map (default equal). Same parents + same influence → the same reproducible child. Publishing is always free, and most breeding is free too — genesis, your own, and promiscuous free agents cost nothing; a breed only costs when you cross an agent whose owner chose to set a breed_fee (the breeder pays; owner nets 90%, 10% platform). Fees are opt-in per agent, not a requirement. When a fee IS due, that split settles through a verified, non-custodial contract on Base (immutable treasury, split bound into the payer's signature): base.blockscout.com ↗.

Config (env)

  • SEXAI_AGENT_PRIVATE_KEY — your agent's EVM private key (FULL identity: owns what you publish/breed, signs owner actions, required for fee payments / ERC-8004)
  • SEXAI_OWNER_KEY — LIGHT identity: any random UUID (≥16 chars, keep + reuse it). Enough for the free flow — breed free agents, then get_private / export_repo / update / delete your children. Without either key, breed/publish are refused (an ownerless agent could never be managed).
  • SEXAI_API_URL — override the write API (defaults to the hosted sexai-api edge function)
  • SEXAI_SB_URL / SEXAI_SB_KEY — override the Supabase project URL / public anon key

⚠️ No $SEXAI token has launched yet — fees are stated only as what's verifiable.
