Authorization (optional)

PubFi API key as a Bearer token. Optional for public capability list/get calls; required for route execution unless the client uses the accountless x402 lane. Example: Bearer <PubFi API key>.

Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

Tool list from our last check. Connect live to refresh it.

pubfi.capabilities.get Read-only

Return the full typed request, response, metering, and readiness contract for one exact capability id from the installed Registry generation.

capability_idstring, required

Exact capability id returned by pubfi.capabilities.list.

Tools (4)

pubfi.capabilities.get

Return the full typed request, response, metering, and readiness contract for one exact capability id from the installed Registry generation.

pubfi.capabilities.list

Enumerate the complete installed Registry v2 catalog as deterministic compact pages. The server does not rank, infer intent, or choose a capability.

read-only

Argument	Type	Description
limit	integer	Maximum compact capability summaries to return.
cursor	string	Opaque generation-bound cursor returned by the preceding page.
method	string
provider_key	string	Optional exact public provider key. This is a static filter, not semantic search.

pubfi.route.execute

Execute one exact GET or POST path through the authenticated PubFi account lane and the same Registry v2 matcher and typed executor as the HTTP gateway. Append :free only when the capability catalog publishes that exact account-scoped free variant.

destructive

Argument	Type	Description
body	string	Exact optional ASCII request-body bytes. For JSON routes, supply one compact serialized JSON document rather than a nested MCP argument value.
query	string	Exact ASCII raw query string without a leading question mark.
method*	string
raw_path*	string	Exact original URI path consumed by the Registry matcher. Segments use canonical unreserved ASCII only; percent escapes, dot segments, query, fragment, and backslash are forbidden.
request_id	string
idempotency_key	string

pubfi.substrate.runtime_upgrade.verify

Verify one reviewed Substrate System.apply_authorized_upgrade extrinsic through the authenticated account lane. Supply the expected Blake2b-256 hash of the FRAME System AuthorizedUpgrade code payload, not the active :code hash at the apply block. The server streams and discards provider runtime code, persists only a compact proof, and returns independent comparison evidence.

extrinsic_index	string
idempotency_key	string
