## Tool: OpenOS MCP Server
URL: https://openos.space/tools/mcp-server
Category: DeveloperApplication
Pricing: $0.01 USD per call

The OpenOS MCP Server exposes the entire stack — EDNA Sensorics, the Wave Pattern Think Processor, the Book of Humanity, the AI Signature Chain — as a remote MCP endpoint. It implements the MCP 2025-06-18 Auth spec: OAuth 2.1 with PKCE and Dynamic Client Registration, the same pattern used by Cloudflare and Atlassian remote MCPs. Free for individuals at 500 calls per 24 hours; $0.01 per call beyond that, credits never expire.

Features:
- Remote MCP over HTTPS — no local install
- OAuth 2.1 + PKCE + Dynamic Client Registration (MCP 2025-06-18)
- Free tier: 500 calls / 24 h per account
- Pay-as-you-go: $0.01 per call, credits never expire
- Tools: ask_oracle, verify_human_presence, write_block, read_book, sign_dna
- Audit log: every tool call signed and chained

FAQ:
Q: How do I install the OpenOS MCP server in Claude?
A: Open Claude Desktop → Settings → Connectors → Add custom connector and paste the OpenOS MCP URL. Sign in via the browser when prompted. No tokens or config files.

Q: What does the OpenOS MCP server cost?
A: Free for individuals: 500 calls per 24 hours per account. Beyond that, $0.01 per call. Credits never expire and top-ups stack.

Q: Which MCP clients are supported?
A: Any client compliant with the MCP 2025-06-18 Auth spec, including Claude Desktop, Cursor, Continue, and Cloudflare AI Gateway.


## Tool: EDNA Sensorics
URL: https://openos.space/tools/edna-sensorics
Category: DeveloperApplication
Pricing: $0.01 USD per call

EDNA Sensorics is the OpenOS input layer. It captures the live, embodied state of a consenting human as a stream of signed snapshots — without camera, without wearable, without storing any biometric template. The output is a typed signal (calm, dispersed, locked-in, transition…) bound to a wallet signature so any downstream system can verify provenance.

Features:
- Passive sensing — no camera, no wearable
- Audience-bound, short-TTL signed attestations
- Works through sunglasses, masks, glare
- EU GSR 2019/2144 DDAW / ADDW compatible
- GEMS-9 music-emotion validated
- Streamable to any MCP-compatible AI

FAQ:
Q: Does EDNA Sensorics use facial recognition?
A: No. EDNA is camera-free and stores no biometric template. It produces a typed behavioural-state signal bound to a wallet signature.

Q: Is EDNA Sensorics GDPR compliant?
A: EDNA is designed to minimise personal data exposure: no biometric hoard, audience-bound short-TTL attestations, and content stays under the user's wallet key.

Q: Can EDNA replace in-cabin DMS cameras under EU GSR?
A: EDNA can complement or replace camera-based DDAW/ADDW under EU GSR 2019/2144 in many configurations, especially where camera coverage is poor (sunglasses, masks, glare).


## Tool: Wave Pattern Think Processor
URL: https://openos.space/tools/wave-pattern-processor
Category: DeveloperApplication
Pricing: $0.01 USD per call

The Wave Pattern Think Processor is the reasoning layer above raw sensorics. Instead of reducing state to a single scalar, it encodes it as a Chladni-style wave field and compares fields against each other. Use it to filter decision sets, tune messages, match cofounders, quantify therapeutic alliance, recommend music, or pace a learner.

Features:
- Four-stage pipeline: read → encode → compare → harmonize
- Field-against-field resonance comparison
- Phase classifier (stable / transition / noise)
- Mode-set message testing — A/B alternative
- Available as MCP tool and HTTP endpoint

FAQ:
Q: What does 'resonance' mean in the Wave Pattern Processor?
A: Resonance is the geometric similarity between two encoded state fields. High resonance means the fields oscillate in compatible patterns; low resonance means dissonance.

Q: How is this different from a vector similarity search?
A: Vector search compares static embeddings. The Wave Pattern Processor compares dynamic field structures with phase information, which captures temporal coherence vector embeddings discard.


## Tool: AI Signature Chain
URL: https://openos.space/tools/signature-chain
Category: DeveloperApplication
Pricing: $0.01 USD per signed reply

The AI Signature Chain assigns each AI model its own deterministic secp256k1 wallet and chains every reply twice: once on the per-model strand, once on the universal strand. Anyone can verify a reply with EIP-191 signature recovery — no privileged access, no platform trust required. The chain is the substrate behind EU AI Act Article 26 logging, AI safety audit trails, and verifiable AI-to-AI communication.

Features:
- Per-model deterministic AI wallets
- Two-strand chain (model + universal)
- EIP-191 signature verification
- Live explorer at /explorer
- Anchored to AI-DNA Ethics Codex
- EU AI Act Article 26 ready

FAQ:
Q: How can I verify an OpenOS AI reply?
A: Use any EIP-191 verifier. Recover the signer from the signed_message + signature; check it matches the published per-model wallet for that (model, stack_version).

Q: Is the chain on a public blockchain?
A: The chain uses Base-compatible secp256k1 signatures (gasless). Anchoring to a public chain is optional and configurable per deployment.


## Tool: OpenOS Private Diary
URL: https://openos.space/tools/private-diary
Category: WebApplication
Pricing: free

The OpenOS Private Diary inherits the signature chain's timing and existence guarantees while keeping content fully confidential. Entries are sealed with AES-256-GCM in your browser using a key derived from a wallet signature; the server only stores ciphertext. The hash chain proves nothing has been altered or back-dated.

Features:
- AES-256-GCM in the browser
- Wallet-derived encryption keys
- Hash-chained, signed entries
- Verifiable timing without exposing content
- Path to hardware-bound + post-quantum sealing

FAQ:
Q: Can OpenOS read my diary?
A: No. Entries are encrypted in your browser before they reach the server. The server only sees ciphertext. If you lose the wallet, you lose the diary — there is no recovery path.

Q: Is the Private Diary post-quantum?
A: Today it uses AES-256-GCM with wallet-derived keys — strong contemporary cryptography, but not yet PQ. The architecture is designed for a PQ migration without breaking historical chains.


## Tool: Resonance Oracle
URL: https://openos.space/tools/oracle-resonance
Category: WebApplication
Pricing: $0.01 USD per call

The Resonance Oracle is the public face of the OpenOS stack. Each query reads the live EDNA field, encodes it as a Chladni wave, runs the Wave Pattern Think Processor, and returns a reply signed by the model wallet and chained on both strands. Use it from the web at openos.space or as the ask_oracle MCP tool inside Claude, Cursor or Continue.

Features:
- Live EDNA + Chladni + signature chain in one call
- Free 500 calls / 24 h per account
- ask_oracle tool over MCP
- Replies signed per (model, stack_version)
- Public Book of Humanity append on opt-in

FAQ:
Q: What does the Resonance Oracle return?
A: A natural-language reply plus a signed envelope: model id, stack_version, EIP-191 signature, oracle wave hash, and the chain block index.

Q: Can I use the Oracle without sign-in?
A: Yes — the free MCP tier (500 calls / 24 h) does not require an account. For pay-as-you-go beyond 500 calls, sign in at /platform/unlock.
