## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-06.

- **Supply Chain Security**: 0/100
  - No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.
  - Known CVEs could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).
  - Install-script risk not yet assessed.
  - Dependency health could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).
- **Provenance & Transparency**: 6/100
  - Repository check failed: no source repository is declared.
  - Provenance check failed: no build-provenance attestation is published.
  - License check failed: no license is declared.
  - Actively maintained (last published 1 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 65/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 2223 tokens (~202/item across 11 items; 11 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 82/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 45% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 11 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 12 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

**Unverified: 2 categories.** Categories scored 0 because we could not verify them: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## Install

### How do I install the SECONDED MCP server?

SECONDED ships as an MCPB bundle, a single file you download and open in an MCP host that supports MCPB bundles, such as Claude Desktop. The host reads the launch command from the bundle's own manifest, so there is no command to copy. Before opening it, check the file's SHA-256 matches the one the MCP registry declares for it, b356b76850d495ab7986c9281216a77a93715dfd39a59b4650e5c8400efec087; the commands to do that are on this page. If it does not match, do not open it.

### 2026-09-30 (score 28)

First indexed and scored.

## MCP tools (11)

### `seconded_get_limits` (~38 tokens)

Show current per-check, hourly, daily and outstanding USD limits and safety switches. null means no user limit. Does not expose wallet keys.

### `seconded_set_limits` (~489 tokens)

Change spending limits at the user's request, without a password. For 'set my daily limit to $20', pass {"daily_usd":20}. Chat can only tighten limits or freeze. Any increase, removal, safety-switch weakening or unfreeze requires the human terminal. These changes require the owner to run the terminal command returned on refusal. There is an absolute $25/day chat ceiling, even when the owner has authorized a higher daily limit in the terminal. Omitted fields stay unchanged. The hard $2.50 per-authorization cap always applies, even if per_check_usd is higher or none. Also changes value_gate, dedupe, loop_brake, alerts and frozen switches.

Input parameters:

- `alerts` (boolean)
- `daily_usd`: USD amount with up to six decimals; omit to leave unchanged. Chat may only lower an existing limit or add a limit. Raising or removing any limit requires owner-terminal confirmation. Chat may set dai…
- `dedupe` (boolean)
- `frozen` (boolean)

- `value_gate` (boolean)

### `seconded_products` (~30 tokens)

Full guide: when to use each check, required inputs, labels and next steps, prices and examples.

### `seconded_quote` (~34 tokens)

Preview the price for this input without signing a payment.

Input parameters:

- `input` (object, required)
- `product` (string, required)

### `seconded_receipt` (~137 tokens)

Recover a check or recent checks by fetching status only. With no check_id, lists the 20 newest checks and any older check still awaiting its receipt, newest first. A result's verification holds the receipt's signed findings and coverage. Never re-signs or re-sends a payment; may sign a read-only ownership proof. After any check error or timeout, call this before checking again. The answer wait can end while payment is pending: continue receipt-only recovery separately until final payment, certified nonpayment, or manual review. Certified nonpayment says not charged and permits retrying the check.

Input parameters:

- `check_id` (string)

### `seconded_wallet` (~126 tokens)

Show the dedicated check wallet address, balances per network and how to fund it, or freeze new authorizations. Wallet switching is terminal-only: seconded-mcp wallet --human --switch back (or newer). Both keys are preserved. Base funding normally becomes available after about a minute, when both readers agree on recent state; Robinhood also uses recent agreement. Final payment confirmation is separate. Pending amounts cannot fund checks yet. Unavailable balances are null, never assumed zero. Never returns a private key; export is a separate human-run CLI command.

Input parameters:

- `action` (string)

### `seconded_trade_check` (~249 tokens)

Use when: Before signing a trade, approval, transfer or permit.
Checks: approval/signature scope.
Send: transaction (unsigned tx) or typed_data (permit).

Cost: $0.25/$1.50 S/M.
Not for: The owner's words or rules; no launch check covers them. New setups: $2.50 max per check, $25 a day; chat only tightens or freezes.
