One tool endpoint for agents, not a custom blockchain integration.
MCP-first - Proof Required for agents
Turn useful work into agent-callable revenue.
Describe a capability. SEED turns it into an MCP-native offer with a bounded mandate, proof requirement, nullifier, receipt, split commitment, and claim right. Agents can discover it, use it, and pay for it without receiving a blank check.
Scope, budget, expiry, and policy are explicit before execution.
Every accepted action can produce a verifiable receipt.
SEED proves the right; user value stays outside SEED custody.
Capability studio
Build the manifest agents will call.
The studio follows the 1C prototype: offer, price, attestations, permissions, workflow, team, publish. Each step updates the MCP manifest preview on the right.
Step 01 - Offer
Name the capability agents can buy.
Describe one useful output, the user it serves, and the proof an agent receives after execution.
Step 02 - Price
Set the economic unit.
Keep the first unit simple: one proof, one review, one license, one translation batch, or one report.
Step 03 - Attestations
Attach the facts that make the offer trustable.
Provider identity, domain control, GitHub ownership, validator status, or a signed external credential can back the manifest.
Step 04 - Permissions
Bound what the agent may do.
The mandate carries scope, budget, expiry, and nullifier policy before the agent receives a result.
Step 05 - Workflow
Declare the proof path.
Request, verify, issue, receipt, and claim-right steps become the machine-readable path an MCP agent can call.
Step 06 - Team
Split the work without leaking the graph.
The manifest records roles and split commitments. Execution and payout remain behind gated non-custody paths.
Step 07 - Publish
Expose the capability as an agent tool.
The public surface is simple: MCP endpoint, manifest, policy, price, and proof-required response.
