Model Context Protocol (MCP) server for freee API integration
Nothing to run from here
ChainChoice published rankings 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
Read-only ChainChoice rankings: sourced, dated comparisons of crypto services, with evidence.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http chainchoice-published-rankings-mcp https://chainchoice.io/mcp
# 2 — ask your agent for something these tools do
# list_categories, get_ranking, get_ranking_for_country and 4 more
ChainChoice published rankings 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 mcp add --scope user --transport http chainchoice-published-rankings-mcp https://chainchoice.io/mcpReconnect, 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.
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
7 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Every category ChainChoice ranks, with how many products it ranks, how many it assessed and left out with a reason, its leader, and its page.
No parameter schema on file.
The published order of one category: rank, product id, name and ChainChoice Score, with the methodology version, the dimension weights and what was assessed. The same order the category page and rankings.json publish.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| category | string | yes | A category id from list_categories, e.g. "exchange" or "hardware_wallet". |
| limit | integer | no | How many rows, from the top (default 10). |
The category's products as a reader in one country sees them: those available there, in order, with each one's published score and rank beside it. When nothing passes the country's availability filter, resultMode is "fallback" and the rows are the published order, none confirmed for that country.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| category | string | yes | A category id from list_categories, e.g. "exchange" or "hardware_wallet". |
| country | string | yes | ISO 3166-1 alpha-2, e.g. "DE". |
| limit | integer | no | How many rows, from the top (default 10). |
For one category (and optionally one product id): each criterion, its weight, and per product the score with the quoted passage, its source URL and the day it was read.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| category | string | yes | A category id from list_categories, e.g. "exchange" or "hardware_wallet". |
| product | string | no | A product id from get_ranking (optional). |
Checks a signed receipt (as ChainChoice serves it, or an issuer envelope) against the keys ChainChoice publishes: whether its content hash matches and its signature is valid. The same verifier as POST /api/v1/verify.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| receipt | object | yes | The receipt JSON, with its signature. |
Reads a query exactly as ChainChoice's search bars do (the same resolver as the homepage, the navigation field and the command palette) and returns that reading: the page it opens (a category's ranked list with the country, monthly volume, sort and filters read from the words, a product's verdict, a two-product compare, a guide), or the question it asks with at most three options, each with the pa
| Parameter | Type | Required | Notes |
|---|---|---|---|
| query | string | yes | The words a reader would type, e.g. "kraken or coinbase" or "best exchange for a German user". |
| country | string | no | ISO 3166-1 alpha-2, e.g. "DE" (optional). |
Once the reader has agreed to go to a provider (consent: true), returns what to hand over: the provider's own address as ChainChoice's catalog records it (never a referral or affiliate link; ChainChoice earns nothing from it), the product's published rank and ChainChoice Score, the reader's country and monthly volume, the ranked list's page with that setup, whether the provider serves that country
| Parameter | Type | Required | Notes |
|---|---|---|---|
| category | string | yes | A category id from list_categories, e.g. "exchange" or "hardware_wallet". |
| product | string | yes | A product id from get_ranking or a search answer. |
| consent | boolean | yes | true only once the reader has agreed to be sent to this provider. |
| country | string | no | The reader's country, ISO 3166-1 alpha-2, e.g. "DE" (optional). |
| vol | integer | no | The reader's monthly amount (optional). |
| query | string | no | The reader's words, if the hand-off follows a search (optional, kept in the receipt). |

ATool-list grade · score 96 / 100
Release 1.5.0 · scanned 5 Nov 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.

This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.

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 ChainChoice published rankings 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.
