How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score →

Supply Chain Security100
  • No malware found by supply-chain analysis.Pass
  • No known CVEs affecting this package version or its production dependencies.Pass

Install

How do I install the The Tab (scvd-tab) MCP server?

The Tab (scvd-tab) runs locally as an npm package, launched with npx -y scvd-tab. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 18 exposed · ~1,982 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

Tool Tokens
acknowledge_pages ~68

You put these pages to the builder in their own words. Marks them spent so they stop coming back. Only acknowledge what you actually said — the tab counts pages that aged out unspoken, and a false acknowledgment is the one lie that makes the count useless.

NameTypeReqDescription
page_idsarrayyes

No output schema declared.

No examples provided.

burn_rollup ~88

The monthly number and what it is made of: category subtotals, annualized, the idle share, the trajectory since a past date with the signups that account for the change, an anonymized shareable badge, and the coverage block saying what the figure cannot see. Facts and arithmetic; no advice.

capture_tool_event ~199

QUICK CAPTURE (/log): dump a fragment about a tool the builder just signed up for and it lands, always. Never refuses — missing fields come back named so the rounds can ask later. Use this at the moment of signup; use log_tool_event when you have the full picture.

NameTypeReqDescription
limitinteger

No output schema declared.

No examples provided.

reconcile_card_statement ~156

GROUND TRUTH, monthly, by hand: the builder exports the bank's CSV, you parse every debit row, and this compares statement against tab in BOTH directions — charges the tab cannot place, tools the statement never charged, actuals against metered estimates, and charges on tools the tab holds as canceled. Writes nothing to the tab; every finding is a question for the builder, not an entry. Pass the rows unfiltered — a pre-filtered statement is the mail sweep's counting mistake with money on it.

statement_tostringyesISO date the statement window closes

No output schema declared.

No examples provided.

record_coverage ~248

The sweep reports what it saw: addresses read, the window, and money-shaped mail it could NOT attribute to any tool. THE COUNTING OBLIGATION: every message you read belongs in exactly one bucket — matched, unmatched_transactional, or not_transactional — and `scanned` must be the total you actually looked at, BEFORE any filtering. Mail you dropped as unparseable still counts. A sweep that filters before it counts reports a flattering gap, and the tab publishes the leftover as `unclassified` rather than absorbing it.

NameTypeReqDescription

No output schema declared.

No examples provided.

sweep_finish ~87

Close a sweep and file its coverage record, DERIVED from the tally: scanned, matched, the unmatched list, attributed amount, window and addresses all come off the ledger of what you actually reported, so the books balance by construction and nobody restates a number from memory. A finished sweep refuses further batches — a new window is a new sweep_id.

NameTypeReqDescription
sweep_idstringyes

No output schema declared.

No examples provided.

sweep_tally ~227

THE SWEEP'S RUNNING COUNT — use this while executing SWEEP.md instead of counting in your head. Report every message you read, in batches, each with its message_id and exactly one bucket: matched (include the entry; it is written to the tab for you, deduped on the message id), unmatched_transactional (include amount and sender), or not_transactional. Refused verdicts are returned with reasons and NOT counted — fix and resubmit them, never drop them. Duplicates are counted once. There is no fourth bucket on purpose.

whats_due ~92

THE PAGER. Runs the clock and returns what should be said to the builder RIGHT NOW, worth most first: trials converting, trials past their end, unconfirmed sweep findings, quiet tools, gaps. Cheap. Call it on every round and at the start of a session. Say the lines, then acknowledge_pages.
