Context Cost

~1,426Tokens (tool definitions)
~1.1 KBTypical response size
Moderate attention impact (1.11% of 128k context)

This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢 Read-only🟡 Write🔴 Delete⚪ Unknown
⚪import_registration(chain_id, token_id, agent_uri, owner, metadata)

Import an ERC-8004 Identity Registry record (chain_id + ERC-721 token_id + agentURI + owner). Idempotent: re-import updates in place. Returns the canonical record with its deterministic bridge DID (did:viridis:erc8004:<chain>:<token>).
