What it is

humanMCP lets you publish poems, essays, notes, images, and typed data artifacts with cryptographic proof of authorship, explicit license terms, and full control over who can access what. AI agents connect via MCP and interact with your content natively.

Content types

Pieces (Markdown files):

Types: poem, essay, note, contact
Access: public / members / locked
Gates: challenge (Q&A), time, manual, trade
Licenses: free, cc-by, cc-by-nc, commercial, exclusive, all-rights

Blobs (typed data artifacts):

Types: image, contact, vector, document, dataset, capsule
Audience: [agent:claude, human:alice, agent:*]
Auto-signed on save if SIGNING_PRIVATE_KEY is set

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)

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
