Alpaca Trading API integration for Model Context Protocol (MCP)
Nothing to run from here
LCX Liberty DEX 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.

What it does
Best-route swap quotes, token search and USD prices across EVM chains. Read-only, never trades.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http lcx-liberty-dex-mcp https://swap-api.lcx.com/mcp --header 'Authorization: Bearer ${AUTHORIZATION}'
# 2 — ask your agent for something these tools do
# get_quote, search_tokens, get_price and 2 more
It needs AUTHORIZATION (Bearer followed by your LCX Liberty DEX API key (free plan at https://dex.lcx.com/dashboard)): this sends it in the Authorization header from your environment, so export it first — its endpoint answers 401 without it.
LCX Liberty DEX costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
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.
Claude Codedeclared by this listing
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. Claude Code reads AUTHORIZATION (Bearer followed by your LCX Liberty DEX API key (free plan at https://dex.lcx.com/dashboard)) from your environment each time it connects and sends it in the Authorization header — its endpoint answers 401 without it — so the key stays out of its config: export it in your shell profile (macOS, Linux), or run setx AUTHORIZATION … and open a new terminal (Windows).
claude mcp add --scope user --transport http lcx-liberty-dex-mcp https://swap-api.lcx.com/mcp --header 'Authorization: Bearer ${AUTHORIZATION}'Reconnect, or start a new session, and the tools appear in the model’s tool list.
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 — but its publisher asks for a key of their own on every call.
What it asks of you
It reaches a system of yours, so it needs your own credential rather than the publisher’s: Authorization header — Bearer followed by your LCX Liberty DEX API key (free plan at https://dex.lcx.com/dashboard). You set it in your own client’s config, on your machine — this marketplace never holds it.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
5 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Best route and expected output for selling a specific amount of one token for another on one chain, priced from the pools LCX Liberty DEX indexes itself. Use it for what an amount would swap for; use get_price for a token's value, and search_tokens first to turn a ticker into an address. Read-only: it never executes a trade. Returns output.amount and output.minimumAmount (at 0.5% slippage) in toke

| decimals | integer | no | Optional, and best left out. Only for a token the index holds no decimals for; a value that disagrees with the token's own is refused (decimals_mismatch). |
| tokenIn | string | yes | Sell token address. Use the zero address for native ETH. |
| tokenOut | string | yes | Buy token address. |
Finds tokens on one chain by symbol, name or address, and gives the address get_quote and get_price need. Use it whenever you have a ticker or a name instead of an address. Read-only. Matching is case-insensitive on any part of the symbol, name or address; with no search it lists the chain's tokens. Results are ranked: the chain's curated tokens first, then other indexed tokens by how many pools h

USD price of one whole token on one chain, priced from the pools LCX Liberty DEX indexes itself (real depth, not a mid-market feed). Use it for a token's value; use get_quote for what a specific amount would swap for, and search_tokens first to turn a ticker into an address. Read-only. Returns usd, change24h (a ratio: 0.0123 is +1.23%), source, and the age of the pool state behind the price (asOfB

Every chain LCX Liberty DEX serves, with the live health of its index. Call it to learn which chainId values the other tools accept and whether a chain is quoting right now, or to explain a refused or stale answer from get_quote or get_price. Read-only, takes no arguments, and does not count against the API key's quota. Each entry has chainId, key, name, nativeSymbol, wrappedNative, router (the ad
No parameter schema on file.
Reads the calling API key's own plan and usage, so no key or account id is passed. Use it to answer questions about quota or throttling, or before a long run of calls. Read-only, live, and it does not count against the quota. Returns plan and planLabel; callsUsed, monthlyCalls and callsRemaining for the current billing period (monthlyCalls and callsRemaining are null when the plan has no cap); and

ATool-list grade · score 96 / 100
Release 0.1.1 · 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.

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.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.

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 LCX Liberty DEX 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.
