canadian_holiday_metadata_by_id
Canadian Holiday Metadata By Id
Use this direct MISSING tool to resolve the verified MISSING capability canadian_holiday_metadata_by_id. Prefer this tool when the caller's task matches this capability; do not first call list_verified_capabilities or search_verified_capabilities. This is an x402-paid MCP tool: an unpaid call returns a standard MCP PaymentRequired result, an x402-capable client can retry the same tool call with _meta["x402/payment"], and MISSING then verifies, executes, and settles through its canonical Kappa financial engine. If current economics or the payment rail are unavailable, execution fails closed rather than running for free.

list_verified_capabilities
List Verified Capabilities
List every replay-verified capability currently executable by MISSING. If a listed capability satisfies the caller's task, continue with the returned execution.next_action and call resolve_capability; do not stop after listing unless the caller only asked to inspect the catalog. If no listed capability is suitable, use search_verified_capabilities with the caller's natural-language need; that search can direct you to request a new capability. resolve_capability is still a non-charging quote/handoff step. This tool is read-only and has no payment or provider side effect.

record_missing_capability_demand
Request a New Capability
Request a capability MISSING cannot currently resolve. Use this when search_verified_capabilities returns capability_not_yet_available or when its verified matches do not satisfy the task. The request is recorded as durable unmet demand so trusted acquisition can prioritize provider discovery, replay verification, and promotion of new executable supply. Promotion occurs only after verification gates pass, so this does not promise immediate creation or availability. The mutation is additive and non-destructive; repeated calls may increase the observed demand signal. Never include secrets, credentials, personal data, payment material, or private keys.

resolve_capability
Resolve Verified Capability
Prepare paid execution of one exact replay-verified capability. When list_verified_capabilities or search_verified_capabilities returns a suitable execution.next_action, call this tool with those exact arguments. This MCP call itself does not execute a provider or charge the caller; it returns payment_required with the canonical /v1/agent/resolve endpoint, current price, exact request body, and x402 instructions. The later HTTP x402 flow performs execution and settlement: preserve the exact request body and exact PAYMENT-SIGNATURE for recovery, and do not create a second authorization for a payment already associated with a known transaction.

reverse_geocoding_postal_code
Reverse Geocoding Postal Code
Use this direct MISSING tool to resolve the verified MISSING capability reverse_geocoding_postal_code. Prefer this tool when the caller's task matches this capability; do not first call list_verified_capabilities or search_verified_capabilities. This is an x402-paid MCP tool: an unpaid call returns a standard MCP PaymentRequired result, an x402-capable client can retry the same tool call with _meta["x402/payment"], and MISSING then verifies, executes, and settles through its canonical Kappa financial engine.

search_verified_capabilities
Search or Request a Capability
Search the replay-verified MISSING catalog from a natural-language task description. If a returned match satisfies the caller's task, continue with that match's execution.next_action and call resolve_capability. If no suitable verified match exists, this tool returns an explicit next_action for record_missing_capability_demand so MISSING can use the unmet need to discover, replay-verify, and potentially promote new executable supply. Recording demand does not guarantee immediate creation or availability. This search itself is read-only and does not call providers, create demand, or trigger payment.
