"A server for querying Oracle SQL database schemas" matching MCP tools:

• schwab_session_status

  schwab-mcp

  Check operator readiness. Returns the operator lifecycle state and clear guidance on what to do next. Free. Lifecycle states: - ready: Operator is warm and fully operational — vault AND pricing model verified. Proceed with tool calls. - warming_up: Operator is initializing (cold start). Try a tool call — it will warm up on demand. - misconfigured: Persistence rejected a query with a permanent SQL error (permission denied, missing relation). Paid tools will fail until the operator repairs the database — retrying does not help. - quota_exceeded: The persistence provider (Neon) answered HTTP 402 — the operator's database has exhausted its compute/storage quota, so the books are locked for billing. Paid tools fail; retrying does NOT help. The operator's Authority must restore capacity (upgrade the plan or wait for the quota reset). Free tools remain available. - not_registered: Operator has no Authority relationship yet. Call register_operator first. - no_identity: Operator nsec is not configured. Deployment issue.

• zfs_ram

  calc.engineer

  Calculate recommended RAM and ARC sizing for a ZFS storage pool based on workload type, pool size, deduplication status, and L2ARC cache size. Computes minimum and recommended RAM in gigabytes, ARC target size, and dedup table overhead. Accounts for workload-specific IO patterns: NAS (sequential, 1GB/TB), database (random, 2GB/TB), virtualization (mixed, 1.5GB/TB). Deduplication adds approximately 5GB per TB for the DDT. L2ARC index requires 1GB RAM per 10GB of L2ARC. Essential for TrueNAS, FreeNAS, and custom ZFS server builds.

• till_vet_merchant

  biii

  MainStreet safe-to-pay preflight on a merchant address. Returns the hosted oracle read (advisory) AND a LOCAL CLASSIFIER verdict computed on this node via trust-core (pure, zero-oracle) — so a verdict holds even if the oracle is down. Vet the RECIPIENT before paying.

• instruments

  wire

  Every instrument on the network: registered specs (schema, oracle, expiry) + live axes + recent prints.

  Connector

• optionality_list_journal

  optionality-mcp

  Server-side sorted, grouped, paginated list of the caller's journal. Sorting and grouping are done in SQL, so each page is a slice of the fully-ordered dataset. Returns ``{total, page, page_size, groups, entries}``; ``groups`` carries per-group counts over the whole set.

• till_trust

  biii

  The TRUST TRIANGLE in one call: composes reputation, standing (LAWBOR proven history, if BIII_LAWBOR_URL set) and settlement (on-chain, if amountMicro given) into ONE verdict (unsafe/unknown/trusted/settled). Reputation is shown as TWO LENSES kept SEPARATE, never merged: `local` = this node's known-bad screen against public lists (no network, decisive — a BLOCK overrides everything) and `oracle` = MainStreet's advisory read (ORACLE-REPORTED, can raise trust but never lower a local block). Fail-closed: absence is never trust; a local BLOCK holds even if the oracle is down. Every verdict carries the list's freshness (asOf/ageDays/stale).
