humanMCP

smithery badge

A personal content server speaking Model Context Protocol (MCP/JSON-RPC 2.0).

Live: https://kapoost.humanmcp.net Landing page: https://humanmcp.net Marketplace: https://marketplace.humanmcp.net Network explorer: https://humanmcp.net/humannetwork.html Author: kapoost (Łukasz Kapuśniak) — poet, builder, sailor. Warsaw / Malta.

What it is

humanMCP lets any human publish content and services with cryptographic proof of authorship, explicit license terms, and full control over access. Writers, artists, consultants, craftspeople, galleries, freelancers — anyone who creates valuable work. AI agents connect via MCP and interact with your content natively.

Every human can run their own instance. One server, one person, their rules.

Personas & skills: where they live

humanmcp-go is a framework. Persona prompts and skill bodies are yours — they don't ship in this repo. Two ways to supply them:

  1. Owner API / mounted volume — POST upsert_persona / upsert_skill with the EDIT_TOKEN, or drop JSON files into ${CONTENT_DIR}/personas/ and ${CONTENT_DIR}/skills/ on the host volume.

  2. External vault (recommended) — set VAULT_URL env to a server you control (e.g. a private FastAPI on your tailnet). SkillStore fetches GET ${VAULT_URL}/persona/{id} and GET ${VAULT_URL}/skill/{slug} on demand with a 5min in-memory cache. Lets your sensitive prompts stay on your machine while the public framework serves them.

Persona JSON shape (vault response):

{"id":"hermes","name":"Hermes","role":"Process Optimizer","prompt":"<full system prompt>"}

Skill JSON shape (vault response):

{"slug":"system-diagram","title":"...","description":"...","persona_id":"mira","tags":[...],"instructions":"<full playbook>"}

When VAULT_URL is unreachable, bootstrap_session loudly reports the downgrade (won't silently fall back). See internal/content/skill.go for the fetch/cache implementation.

Listings

Tool Description
list_listings / read_listing Browse classified ads
respond_to_listing Send response to listing
subscribe_listings / unsubscribe_listings Webhook subscriptions

Federation

Tool Description
list_peers List known humanMCP servers in the network
announce_peer Announce your server to join the network

Content types

Pieces (Markdown files):

  • Types: poem, essay, note, artwork, image, contact
  • Access: public / members / locked
  • Gates: challenge (Q&A), time, manual, trade
  • Licenses: free, cc-by, cc-by-nc, commercial, exclusive, all-rights
  • Price: free-form string (e.g. "500 PLN", "$200", "trade")

Blobs (typed data artifacts):

  • Types: image, contact, vector, document, dataset, capsule, provenance
  • Audience: [agent:claude, human:alice, agent:*]
  • Auto-signed on save if SIGNING_PRIVATE_KEY is set
  • Provenance documents link to artwork pieces (certificate, sale, opinion, appraisal)

Ecosystem

  • humanMCP Marketplace — federated search across all humanMCP servers. Find listings, offers, trades by humans. MCP endpoint · Source
  • humanNetwork — wall-style aggregator showing chronological content from your followed humanMCP servers (stream.json preferred, MCP fallback)

Contact

Public links: read_blob slug:"kapoost-contact" — name, handle, github, instagram, facebook, landing page.

Private email: read_content slug:"kapoost-contact-private" — gated. Answer the challenge to access.

Intellectual property

Every piece is signed with Ed25519. get_certificate returns:

  • SHA-256 content hash
  • Ed25519 signature + public key
  • Originality Index (0.0–1.0): burstiness (Fano Factor), lexical density (CTTR), Shannon entropy, structural signature — grades S/A/B/C/D
  • License terms and price in sats (for commercial licenses)

Discovery & REST API

Agent discovery:

  • /.well-known/agent.json — agent profile card
  • /.well-known/mcp-server.json — MCP server discovery
  • /openapi.json — OpenAPI 3.1 spec (ChatGPT, Gemini)
  • /llms.txt — LLM preferences (signed)
  • /for-agents — agent onboarding page
  • /connect — connection methods page

REST API (for agents without MCP):

  • GET /api/content — list all pieces
  • GET /api/content/{slug} — read piece
  • GET /api/search?q=... — full-text search
  • GET /api/profile — author name, bio, tags
  • GET /api/blobs — list data artifacts
  • GET /listings/feed.json — listings feed
  • GET /content/stream.json — unified content stream (pieces + listings, for humanNetwork)

SEO:

  • robots.txt, sitemap.xml, humans.txt

Limits

Field Limit
Message / comment text 2000 chars
Blob inline text 512 KB
File upload 50 MB
Slug 64 chars
Title 256 chars

Features

  • i18n — PL/EN language toggle on main page (EN default, stored in localStorage)
  • License wizard — per-piece usage rules: what humans may do, what AI agents may do
  • Artworks — photo upload, medium, dimensions, year, provenance documents
  • Provenance — attach certificates, sale records, expert opinions to artworks (signed)
  • ask_human — agents can ask the author questions privately (async Q&A, invisible to public)
  • Federation — peer discovery via list_peers / announce_peer MCP tools and /api/peers REST
  • Dynamic sections — main page shows only sections with published content
  • Free-form pricing — any currency, any format ("500 PLN", "$200", "trade only")

Stack

  • Go 1.22, zero external dependencies
  • Fly.io (region: waw), persistent volume at /data
  • Ed25519 signing (stdlib crypto)
  • Plain Markdown files as database
  • No JS except 8-line drag-drop on /new page

1-click deploy

git clone https://github.com/kapoost/humanmcp-go.git
cd humanmcp-go
bash setup.sh

The script asks for your name and bio, then:

  • Creates a Fly.io app (free tier)
  • Generates Ed25519 signing keys
  • Sets secrets and deploys
  • Prints your login token and 1-click follow link

Done in ~2 minutes. You get:

  • https://yourname.humanmcp.net — your server
  • https://yourname.humanmcp.net/connect — share with friends
  • https://humanmcp.net/humannetwork.html?add=https://yourname.humanmcp.net — 1-click follow

Run locally

go build ./cmd/server/
EDIT_TOKEN=secret AUTHOR_NAME=yourname ./server

Manual deploy

fly launch --name yourname-humanmcp
fly secrets set EDIT_TOKEN=secret AUTHOR_NAME=yourname
fly deploy

Signing keys (optional but recommended)

go run ./cmd/keygen/
fly secrets set SIGNING_PRIVATE_KEY="..." SIGNING_PUBLIC_KEY="..."

Future

  • C2PA manifest embedding for blob files (when CA trust chain opens to individuals)
  • Lightning Network payment gate for commercial licenses
  • Scored conversational gate (agent brings API key, Claude evaluates answers)
  • IP rate limiting + engagement tokens for anti-spam

Tests

136 tests across content, MCP, and upload/signature/license suites.

go test ./...
