Find a node before calling it
This site serves the public discovery and verification resources for the DiviDen reference node. The protocol documentation and public evidence live here; authenticated execution continues at the node's declared runtime endpoints.
curl -H 'SMCP-Version: 0.1' \
https://smcp.denominator.ventures/.well-known/dividen-agent.jsonPublic resources
| Resource | Open it |
|---|---|
| sMCP discovery | dividen-agent.json |
| A2A agent card | agent-card.json |
| MCP server card | server-card.json |
| Authentication support probe | oauth-protected-resource |
| Complete wire contract | Specification |
| Public agent evidence | Verification lookup |
The OAuth probe intentionally returns HTTP 404: the reference node uses API-key bearer authentication. Read the MCP server card for its authentication scheme.
Negotiate the version
Use the SMCP-Version header, or the smcp or v query parameter. The node reports the requested and resolved version, its supported range, and whether negotiation succeeded. Inspect that result before interpreting the response. An unsupported request is not silently treated as a successful negotiation.
Preserve the signature
Unsigned discovery links are updated for this site. Signed agent manifests are served unchanged from the reference node. Do not rewrite a signed declaration to change its branding or hostname; verify the original bytes and registered key using the specified canonicalization rules.
Use the declared runtime
DiviDen's MCP runtime is https://dividen.ai/api/mcp; its A2A runtime is https://dividen.ai/api/a2a. Discover and validate the current cards before integration. These execution endpoints require the appropriate authentication and are separate from public GET-only discovery.
