Alpaca Trading API integration for Model Context Protocol (MCP)
Nothing to run from here
LogicNodes is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.

This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.

Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.

Validates an address for a chain and returns its canonical form. EVM: EIP-55 (a wrong checksum is refused, never corrected). Aptos: AIP-40 strict form. Says only what can be known offline; it never guesses what kind of account an address is.

[FREE: 25 calls/day, then $0.001 USDC per call via x402] Spot USD price of a crypto asset by ticker (BTC, ETH, SOL, USDC, APT, LINK, ...), read live from Coinbase and Kraken. A price is returned only when both answer and agree within 1%; the answer is their midpoint, with both readings and the deviation.

[FREE: 25 calls/day, then $0.005 USDC per call via x402] Before your agent signs an EVM transaction: simulates it on the current chain state and reports every token and native-coin movement in and out of the sender, decodes what it asks for (ERC-20 approve/permit, Permit2, setApprovalForAll, transfers), checks the counterparty (contract or wallet, sanctions lists) and, if you pass expectedTo, flag

Validates an address against the Aptos address standard (AIP-40) and returns its canonical form: special addresses (0x0-0xf) as short form, all others as 0x + 64 digits.

Add, subtract, multiply, divide, raise to an integer power, compare, or take a percentage, on decimal STRINGS with exact arithmetic (no floating point). The result is rounded only to the scale and rule you choose, and the response says whether rounding changed the value. JSON numbers are refused because they lose precision.

[FREE: 25 calls/day, then $0.001 USDC per call via x402] Monthly payment, total interest and total paid for a fixed-rate amortizing loan, in exact arithmetic. The payment is rounded once to the currency scale and the final payment absorbs the rounding so the balance ends at exactly zero.

[FREE: 25 calls/day, then $0.003 USDC per call via x402] Logs emitted by one contract in a block range of at most 2000 blocks, optionally filtered by topics. Refuses (rather than truncates) when more than 1000 logs match, so an answer is always complete.

[FREE: 25 calls/day, then $0.001 USDC per call via x402] Decodes transaction calldata against an ABI that YOU supply and returns the function, its signature and each argument. If the selector is not in your ABI it says so and lists the selectors it does have; it does not guess from a selector database. An ABI that does not belong to the target contract can decode to plausible nonsense.

[FREE: 25 calls/day, then $0.001 USDC per call via x402] Decodes one event log (its topics and data) against an ABI that YOU supply and returns the event name and arguments. If no event in your ABI matches topic0 it says so rather than guessing from a database of known events.

[FREE: 25 calls/day, then $0.002 USDC per call via x402] Given a transaction hash, lists the ERC-20 transfers in its receipt and, if you give expectations (payee, asset, amount, payer), says whether a successful transaction contains a matching transfer. Use it to check an x402 or other USDC payment. A match proves tokens moved; it does not prove what the payment was for.

Reads an agent from the ERC-8004 identity registry on Base: its owner address and the registration URI it points to, at one stated block. The URI is reported, not fetched (fetching arbitrary URLs for you is not this tool's job). An id that was never minted is NOT_FOUND.

Summarises the feedback posted about an agent in the ERC-8004 reputation registry on Base, at one block: number of distinct clients, number of feedback entries, the registry's own summary value, and each client's latest entry (value, tags, revoked). It is EVIDENCE, not a verdict: anyone can post feedback from any address, so many clients is not proof of many people, and tag text is free text writt

Step 1 (free) of the verified-operator badge. Returns one line to publish EITHER as the content of https://<domain>/.well-known/logicnodes-verify.txt OR as a DNS TXT record at _logicnodes.<domain>. Then call operator_verify_check. The badge proves control of the domain and is valid 365 days.

[PAID $10.00 USDC per call via x402] Step 2 of the verified-operator badge: reads https://<domain>/.well-known/logicnodes-verify.txt and the DNS TXT record _logicnodes.<domain>; if either holds the line from operator_verify_start, the badge is recorded for 365 days and shows in counterparty_check and at /v1/operators/<address>. A failed check is an error (and errors are never charged).

ATool-list grade · score 93 / 100
Release 1.0.0 · scanned 28 Oct 2026
Graded from the tools this server lists, not from its source code.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

| Term | Level | What it prices | Points |
|---|---|---|---|
| capability-exposure | moderate | capability blast radius (moderate) — client exposure if the model is manipulated | −3 |
| coverage-honesty | manifest | inspection depth (manifest) — how much of the target the scan could see | −4 |
score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish LogicNodes can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
