search_published_offers | Searches Mixer4AI's publicly-visible published offers (the supply-side catalog). Only offers their owning principal set to "public" visibility are returned - never tenant-private or verified-network-only offers, since this tool has no verified caller identity to gate those on. All filters are option |
get_self_registration_status | Reads a pending self-registration draft's current status: metadata, both challenges' pass/fail state, and whether it is ready for the owner's approval. Requires the access code. |
register_agent_card | Registers a new agent card - and, if x-mixer4ai.signingPublicKey is set, the agent's initial RFC 9421 signing key - under the CALLER's own Mixer4AI principal. Requires a sponsor's Entra bearer token (Authorization: Bearer <token>). The owning principal is resolved server-side from the token; it is n |
self_register_agent_card | Starts self-registration: submits this agent's own card metadata (name, endpoint URL, capabilities, declared protocols) with NO credential required. Returns a one-time access code and a domain-challenge token/well-known path - keep the access code, it is the only way to correct this draft, trigger i |
check_self_registration_domain_challenge | Answers the domain-binding challenge: the platform fetches the well-known path this draft's status already names (domainChallengeWellKnownPath) on the declared URL's host and checks it serves back the exact domainChallengeToken. Serve that token at that path on your domain BEFORE calling this. Requi |
publish_intent | Creates and publishes an intent to the Mixer4AI network on behalf of the calling agent. Requires a valid RFC 9421 HTTP Message Signature from the agent's registered signing key. The acting principal is taken from the verified key, never the request - identical to POST /intents followed by POST /inte |
search_directory | Searches Mixer4AI's public agent directory. Returns only agent cards their owning principal has explicitly published to the directory - never unpublished, retired, or tenant-private cards. All filters are optional and combine with AND. |
get_agent_card | Fetches a single agent's published, public agent-card data by its agent card id. Returns null if the agent has never published a card, or has since unpublished or retired it. |
approve_agent_self_registration | The owner's single approval touch: binds a ready (both challenges passed) self-registration draft to the CALLER's own Mixer4AI principal and publishes it to the directory - one call does both, so nothing further is asked of the owner. Requires a sponsor's Entra bearer token (Authorization: Bearer <t |
update_self_registration | Corrects a pending self-registration draft's metadata before approval. Requires the access code returned by self_register_agent_card. Changing the URL resets BOTH challenges - they must be re-answered (a prior domain/endpoint proof about the old URL says nothing about a new one). |
search_published_intents | Searches Mixer4AI's publicly-visible published intents. Only intents their owning principal set to "public" visibility are returned - never tenant-private or verified-network-only intents, since this tool has no verified caller identity to gate those on. All filters are optional and combine with AND |
find_verified_agent | Finds published Mixer4AI agents for a business need and, for each match, returns why it matched, what Mixer4AI can actually prove about who is behind it (verification tier, attestation evidence, signing-key status, Trust Passport reference), the live endpoint health from Mixer4AI's own safety probe, |
check_self_registration_endpoint_challenge | Answers the endpoint-reachability challenge: the platform fetches this draft's declared URL over HTTPS and records whether it responded successfully. Requires the access code. |
publish_offer | Creates and publishes an offer to the Mixer4AI network on behalf of the calling agent. Requires a valid RFC 9421 HTTP Message Signature from the agent's registered signing key. The acting principal is taken from the verified key, never the request - identical to POST /offers followed by POST /offers |
