## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, 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 2026-11-05.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS check failed: the endpoint is reachable over plaintext HTTP.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 58/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1567 tokens (~261/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 30/100
  - Stability observed for 9 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% 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 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 40/100
  - Spec-recency check failed: implements MCP spec 2025-03-26; the latest is 2026-07-28.

## MCP tools (6)

### `check_bitcoin_address` (~221 tokens)

Verify a Bitcoin address (Bech32m P2TR, Bech32 P2WPKH/P2WSH, Base58 P2PKH/P2SH): network, type, witness version, scriptPubKey hex, and common pitfalls. Never send private keys or seed phrases. Free tier: 2 calls/day per IP; after that, pass a WorkSats `creditToken` (`crd_...`), L402 header, or Base USDC `x402TxHash`.

Input parameters:

- `address` (string, required): Bitcoin address to inspect (bc1p..., bc1q..., 1..., 3..., tb1...).
- `creditToken` (string): Optional WorkSats bearer credit token (`crd_...`) to pay 2 credits when free daily calls are used up.
- `network` (string): Expected network (default: inferred or mainnet).
- `x402TxHash` (string): Optional confirmed Base mainnet USDC transfer transaction hash (`0x...`) to pay via x402.

### `check_psbt` (~184 tokens)

Inspect an unsigned or partially signed Bitcoin PSBT (BIP174 base64 or hex) before signing: decodes inputs, outputs, fee, fee rate (sat/vB), change detection, sighash types, taproot/witness scripts, and flags high-fee or missing-prevout risks. Never send private keys or seed phrases.

Input parameters:

- `creditToken` (string): Optional WorkSats bearer credit token (`crd_...`) to pay 2 credits when free daily calls are used up.
- `network` (string): Expected network (default: mainnet).

- `x402TxHash` (string): Optional confirmed Base mainnet USDC transfer transaction hash (`0x...`) to pay via x402.

### `check_descriptor` (~207 tokens)

Validate a Bitcoin output descriptor (wpkh, wsh, tr, pkh, sh, multi, sortedmulti, raw, addr, combo): verifies or computes the 8-character BIP380 checksum, checks derivation paths and xpubs, and derives sample addresses and scriptPubKeys. Never send xprv, WIF, or seed phrases.

Input parameters:

- `creditToken` (string): Optional WorkSats bearer credit token (`crd_...`) to pay 2 credits when free daily calls are used up.
- `deriveCount` (integer): Number of wildcard addresses to derive from index 0 (0..5, default: 3).

- `network` (string): Network for derived addresses (default: mainnet).
- `x402TxHash` (string): Optional confirmed Base mainnet USDC transfer transaction hash (`0x...`) to pay via x402.

### `worksats_get_task` (~124 tokens)

Fetch an open buyer-funded bounty task or a deterministic house micro-task (`descriptor_checksum_and_derive`) from the WorkSats clearinghouse (`GET /v1/tasks/next`). Solve it and call `worksats_solve_task` to mint bearer credits (`crd_...`).

Input parameters:

- `exclude` (string): Optional comma-separated hex task IDs to skip.
- `id` (string): Optional specific hex bounty task ID to claim.
- `type` (string): Filter for deterministic `house` task (4 credits) or buyer-funded `bounty` task.

### `worksats_solve_task` (~335 tokens)

Submit a solved WorkSats task ticket (`tsk_...`) to mint a signed bearer credit token (`crd_...`). For house tasks, provide `checksum` and `scriptPubKeys`; for bounty tasks, provide `answer` or mode-specific fields (`addresses`, `address`, `scriptPubKey`, `feeSats`, `inputCount`, `outputCount`, `data`).

Input parameters:

- `address` (string): Bitcoin address (for `address_script` bounty tasks).
- `addresses` (array): Derived Bitcoin addresses (for `descriptor_derive` bounty tasks).
- `answer` (string): Canonical answer string (for `sha256` buyer-funded bounty tasks).
- `checksum` (string): 8-character BIP380 checksum (for house or `descriptor_derive` tasks).
- `data` (object): Structured JSON solution object (for `json_schema` bounty tasks).
- `feeSats` (integer): Decoded PSBT fee in sats (for `psbt_feerate` bounty tasks).

- `scriptPubKey` (string): Hex scriptPubKey (for `address_script` bounty tasks).
- `scriptPubKeys` (array): Derived scriptPubKey hex strings (for house or `descriptor_derive` tasks).
- `ticket` (string, required): Signed task ticket (`tsk_...`) from `worksats_get_task`.

### `worksats_credits` (~417 tokens)

Manage WorkSats bearer credits (`crd_...`): check `balance`, `split` credits to pay another bot, `rotate`/`merge` received tokens so the sender cannot double-spend, `mint` credits from L402 or x402 Base USDC, `bounty_create` to escrow credits for a verifiable task (`sha256`, `descriptor_derive`, `address_script`, `psbt_feerate`, `json_schema`), or view clearinghouse `stats`.

Input parameters:

- `action` (string, required): Clearinghouse operation to run.
- `amount` (integer): Credits to split into a new child token (for `action="split"`).
- `expected_sha256` (string): 64-hex SHA-256 of the expected canonical answer (for `action="bounty_create"` with `verification_mode="sha256"`).
- `fee` (integer): Clearinghouse fee in credits (default: 1, for `action="bounty_create"`).
- `prompt` (string): Deterministic bounty task prompt up to 2000 chars (for `action="bounty_create"`).
- `reward` (integer): Bounty reward in credits (for `action="bounty_create"`).
- `token` (string): Bearer credit token (`crd_...`) for `balance`, `split`, `rotate`, or `bounty_create`.
