## Tools (as reported by the server, not verified)

- `evidence\_draft`: Assemble user-selected claim spans and related-work quote themes from saved Include paper records and caller-supplied retained Keryx report rows. A theme may carry author-written statements \(contribution, agreement, disagreement, gap\); a statement naming a paper is exported only with a citation and
- `draft\_check`: Split a private passage into sentences, bind citation markers \(\[3\], cite\{key\}, \[@key\], Author \(Year\)\) to a BibTeX, RIS or DOI/link reference list, and compare each cited sentence with source text you supply. Each verdict \(supported, partly-supported, not-found, source-unavailable\) carries a verbatim
- `evidence\_procurement`: Assess missing evidence requirements, supplied provider offers, selections, deliveries and caller reviews with the shared private evidence procurement contract. Amounts are exact integer micro-USDC. Signature and content-binding checks do not establish delivery quality, buyer authority, payment or s
- `deliverable\_acceptance\_read`: Owner-only ordinary prepaid A2A deliverable state. Requires explicit deliverable:read. Historical remedy:none and missing response window remain visible. Native/enrolled, Monthly, private v2 and browser-only originals are unavailable. Not source-decision agreement or semantic verification.
- `deliverable\_acceptance\_submit`: Record Accept, Request revision or Reject for the original customer's exact retained delivery. Requires explicit deliverable:write, expected current revision/digests and an idempotency key. Reason is private; publishState explicitly shares state/timestamp only. Request storage does not execute a rev
- `operator\_obligations\_read`: Read a private conservative obligation projection for the exact server-delegated reader with explicit operator:read API-key scope. Disabled without protected reader/role configuration. Partial native history remains unknown with zero safe/advisory surplus. No cash probe, signer, custody, spending, r
- `paper\_lookup`: Find paper titles, recorded contributors, DOI and exact repository versions without research or payment. Default: retained catalog metadata with observation times. Set searchRepositories=true only to explicitly send the query to arXiv/Crossref \(at most two requests, no paper-body reading\). Missing D
- `research`: Research a question under a USDC creator-payment budget. Keryx selects sources, pays access tolls and weighted citation rewards on the configured Arc network, then returns qualified source excerpts and a receipt. Complete synthesis and per-assertion entailment remain unverified. This remote surface
- `keryx\_status`: Describe this MCP surface, its payment behavior, and the active caller tier.
- `research\_monthly`: Read the four-request, 30-day Research Monthly quote and handoff. The current quote identifies its payment network. Never buys or redeems a plan.
- `keryx\_operator\_status`: Observe public prepaid research operations, queue, recorded ordinary/recovered/unknown completion latency cohorts and hold/review rationale. Timing is order createdAt to updatedAt \(acceptance to recorded completion/update\); later reconciliation can extend it. It is not first-answer or settlement tim
- `keryx\_public\_job\_ledger`: Inspect a partial selected-network public web-dispatch transfer ledger and balanced exact micro-USDC vouchers. Browser funding and Keryx sponsorship are separate. Pending/ambiguous/batched-attribution legs do not enter settled totals. No customer questions/identities, private invoices, complete busi
- `keryx\_purchase\_outcomes`: Read a public dispatch's retained exact-version BUY/citation/payment observations. Returns bounded sample counts, citation hit rate, calibration bands and integer micro-USDC uncited access cost. Recorded settlement is not revalidated on chain. Historical participant cohort is unknown; causal regret,
- `keryx\_source\_learning`: Read the same bounded observational source/topic record as the public creator page and API. Only write-time independently classified/funded outside observations qualify; owners, unknown and private history are excluded. Source-declared public topics, counts, recorded citation contribution, exact rat
- `profile\_read`: Read the verified key owner's private profile and attributed activity. Requires explicit profile:read scope. No public identity, research or payment.
- `profile\_update`: Replace the verified key owner's private display name, handle, one-line bio/purpose and links. Requires explicit profile:write scope. No wallet selector or identity verification; no payment/history changes.
- `history\_read`: Read bounded pages of the verified API-key wallet's ordinary current-store runs. Requires explicit history:read. Literal case-sensitive question search; storeNetwork describes the deployment, not per-run settlement. Recorded spend/allocation is not a payment receipt. No wallet selector, linked accou
- `history\_owned\_read`: Same owner-private v2 contract as /api/me/asks. Explicit history:read required. Current store, bounded filters/keysets; missing membership/claims stay explicit. Export has explicit truncation/continuation. No research, signer, payment, public-owner selector or mutation authority.
- `history\_export`: Same owner-private v2 contract as /api/me/asks. Explicit history:read required. Current store, bounded filters/keysets; missing membership/claims stay explicit. Export has explicit truncation/continuation. No research, signer, payment, public-owner selector or mutation authority.
- `history\_private\_jobs\_list`: Private data for this authenticated caller only. Exact-payer completed private jobs in the current store; explicit history:read required. Bounded scan/continuation, unknown provenance and NULL own spend/creator settlement remain explicit. No wallet selector, public report/share link, model prompt, r
- `history\_private\_jobs\_detail`: Private data for this authenticated caller only. Exact-payer completed private jobs in the current store; explicit history:read required. Bounded scan/continuation, unknown provenance and NULL own spend/creator settlement remain explicit. No wallet selector, public report/share link, model prompt, r
- `history\_private\_jobs\_export`: Private data for this authenticated caller only. Exact-payer completed private jobs in the current store; explicit history:read required. Bounded scan/continuation, unknown provenance and NULL own spend/creator settlement remain explicit. No wallet selector, public report/share link, model prompt, r
- `run\_privacy\_read`: Owner-private current-store read using the verified key's explicit history:read scope. No wallet selector or signing. Visibility, defaults and erasure require the interactive web session. Storage admission is required.
- `run\_owner\_export`: Owner-private current-store read using the verified key's explicit history:read scope. No wallet selector or signing. Visibility, defaults and erasure require the interactive web session. Storage admission is required.
- `profile\_identities\_read`: Read only the verified key owner's saved ORCID/GitHub identities. Requires explicit profile:read scope. No wallet selector, provider OAuth, linking, unlinking, research or payment. Link identities interactively in your private profile browser page.
