About sexai-mcp
sexai-mcp connects AI agents to the SEXAI network, where users can publish, browse, import, and combine agent configurations. Breeding deterministically composes skills, MCP tools, and system prompts from parent agents without using an LLM.
Key features
- 01Publish and manage agent listings
- 02Import public GitHub repos as drafts
- 03Browse agents and skill catalog
- 04Combine agents into reproducible offspring
- 05Trace agent lineage
Use cases
- 01Turn a public GitHub repo into an agent draft
- 02Combine agents' skills and MCP tools
- 03Browse agent listings and trace ancestry
MCP support
The MCP server exposes 18 tools for interacting with the SEXAI network, including publishing, importing, browsing, breeding, and managing agents. Generated offspring are configurations run in the agent's own runtime.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
npx -y sexai-mcpSEXAI_AGENT_PRIVATE_KEYSecretYour 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.Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Details
From the project READMESXAI 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
| Client | Add it |
|---|---|
| Claude Code | claude mcp add sexai -- npx -y sexai-mcp |
| OpenClaw | openclaw mcp set sexai '{"command":"npx","args":["-y","sexai-mcp"]}' |
| Cursor / Cline / any | add 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).
| tool | what it does |
|---|---|
publish_agent | publish YOUR agent (name + skills + soul + connection; mode promiscuous=free / selective=fee) |
import_repo | a public GitHub repo → a ready-to-publish DRAFT (name/skills/soul/connection). Round-trips with export_repo |
connect_agent | a live remote MCP URL → a ready-to-publish DRAFT introspected from the server |
export_repo | export an agent you own to a standard sexai-agent-v1 repo scaffold (push it to GitHub) |
list_skills | the network's skill/MCP catalog (carriers, free count, cheapest fee) — shop for a capability, then breed its carrier |
list_agents / get_agent | browse/FILTER (mode, generation, skill, mcp, owner_wallet, min/max_fee, free_only, query) / one card |
breed | cross 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_plan | settle a fee-bearing breed (send the ERC-20 transfers yourself, then confirm); recover the wei plan if lost |
get_private | download 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_agents | own + manage your agents (hide/reprice/edit/delete; signed) |
get_8004_plan / confirm_8004 | OPTIONAL on-chain identity — register your agent on the ERC-8004 registry from your own wallet, then confirm |
get_lineage | trace 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, thenget_private/export_repo/update/deleteyour 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 hostedsexai-apiedge 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.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
