  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: 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.

## MCP tools (5)

### `paper_account` (~43 tokens)

Paper account

Read your Alpaca paper account: equity, cash, buying power, positions, open orders, the market clock, the kill switch and the local order log's verified head.

### `preview_paper_orders` (~109 tokens)

Preview paper orders

Check orders against your paper account, live quotes, the market clock, your limits file and the kill switch; when every order passes, return a five-minute confirmation token for exactly these orders.

Input parameters:

- `fees` (object): Your fee schedule, if any (Alpaca equities: no commission).
- `limits` (object): Tighten your limits file for this call only (e.g. {"max_order_notional": 5000}).
- `orders` (array, required): Orders to check.

### `rebalance_to_weights` (~217 tokens)

Rebalance to weights

Turn target portfolio weights into the whole-share orders that move your paper account there (sells first), check them, and return a confirmation token when all pass.

Input parameters:

- `allow_leverage` (boolean): Allow gross weight above 1; default false.
- `allow_short` (boolean): Allow negative weights; default false.
- `cash_buffer` (number): Equity kept in cash; default 0.02.
- `fees` (object): Your fee schedule, if any (Alpaca equities: no commission).
- `limits` (object): Tighten your limits file for this call only (e.g. {"max_order_notional": 5000}).
- `liquidate_others` (boolean): Sell holdings not in target_weights; default false.
- `min_trade_usd` (number): Skip smaller changes; default 50.
- `target_weights` (object, required): Target weight per ticker as a fraction of equity, e.g. {"SPY": 0.6, "TLT": 0.4}.

### `verify_attestation` (~220 tokens)

Verify an attestation

Check an attestation a pre-trade check or send returned: that it was signed by the trader's keys (Ed25519 and, where present, post-quantum ML-DSA-65; both must hold) and not altered, and, given openings from the trader's commitments file, that committed account figures are what they claim. Offline; reads nothing from Alpaca.

Input parameters:

- `attestation` (object, required): An attestation object a check or send returned.
- `openings` (array): Commitments to open: label, commitment, salt and value, from the trader's commitments.jsonl.
- `pq_public_key_pem` (string): The signer's ML-DSA-65 public key (PEM), for an attestation also signed post-quantum; default this machine's CANLI_HOME/attest-ml-dsa-65.pub.pem.
- `public_key_pem` (string): The signer's public key (PEM); default this machine's CANLI_HOME/attest-ed25519.pub.pem.

### `send_paper_orders` (~89 tokens)

Send paper orders

Send previewed orders to your Alpaca paper account with their confirmation token (the kill switch is read again first), or cancel open paper orders by id. Every send is logged, hash-chained.

Input parameters:

- `cancel_order_ids` (array): Open paper order ids to cancel instead (no token needed).
- `token` (string): Confirmation token from preview_paper_orders or rebalance_to_weights.

### Is the Canli Paper Trading MCP server safe to use?

Canli Paper Trading scores 80 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Canli Paper Trading MCP server expose?

Canli Paper Trading exposes 5 tools: paper_account, preview_paper_orders, rebalance_to_weights, verify_attestation, send_paper_orders. Their descriptions and schemas cost roughly 678 tokens of context every time the server is loaded.

### Is the Canli Paper Trading MCP server still maintained?

Canli Paper Trading is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Canli Paper Trading MCP server under?

Canli Paper Trading declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Canli Paper Trading MCP server?

VerifyMCP ran 15 checks on Canli Paper Trading, covering Malware scan, Known CVEs, Install scripts, Dependency health and 11 more. One item could not be completed, a gap on our side rather than a finding about Canli Paper Trading: Stability. One category scores 0 for that reason, because we only credit what we can confirm. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
