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.

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 — visual explorer aggregating content from the growing network of humanMCP servers

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

SEO:

• robots.txt, sitemap.xml, humans.txt

Limits

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

Run locally

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

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.
