Alpaca Trading API integration for Model Context Protocol (MCP)
Nothing to run from here
Chia 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
MCP server for the Chia blockchain. Read-only full-node access via Coinset hosted nodes, 36 tools.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user chia-mcp '--' npx -y chia-mcp
# 2 — ask your agent for something these tools do
# get_blockchain_state, get_block, get_block_record_by_height and 35 more
Chia 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. This one runs on your machine: your client starts Chia as a process under your own user, with your files and your network, so the tool surface below is what it can do to your computer rather than to a server somewhere else. Its scan result is on the Security tab — read the surface before you approve it.
Claude Codedeclared by this listing
This is a public server: you run it yourself and this marketplace is not in the path. You need Node.js — the current LTS (24) is the safe choice; npx comes with it. Claude Code registers it in one command; --scope user makes it available in every project. The '--' is in quotes so that PowerShell passes it on.
claude mcp add --scope user chia-mcp '--' npx -y chia-mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it runs from its publisher’s own package: 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 your client uses to start the process locally. A local server runs with your file system and your network, which is why it is priced without metering.
What you approve
38 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Get all items currently in the mempool with full details. WARNING: Can return very large responses (10+ MB on mainnet). Consider using get_all_mempool_tx_ids first to get transaction IDs, then fetch individual items with get_mempool_item_by_tx_id.
No parameter schema on file.
Estimate the fee required for a transaction to be included within target times. Provide target times in seconds (e.g., [60, 300, 600] for 1min, 5min, 10min). Returns the total estimated fee in mojos for the given cost at each target time. current_fee_rate is mojos per CLVM cost unit. If neither…

A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.

Live transportnot available
Tools were statically extracted from the published source (38 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, scan the running server: --command "npx -y <package>".
1 of the 38 recovered tools are registered only when process.env.CHIA_MCP_ENABLE_PUSH_TX === '1' || process.env.CHIA_MCP_ENABLE_PUSH_TX === 'true' holds (dist/tools.js:672) — typically when a key or option is configured. They are part of the server's surface and were analysed; a server started without that configuration exposes only the other 36.
1 of the 38 recovered tools are registered only when !rpc.getBaseUrl().includes('coinset.org') holds (dist/tools.js:706) — typically when a key or option is configured. They are part of the server's surface and were analysed; a server started without that configuration exposes only the other 36.

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 Chia 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.
