Common questions

Is FirstKey safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 43 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

FirstKey MCP Server

An MCP (Model Context Protocol) server running as a canister on the Internet Computer. One integration point that every MCP-compatible agent framework consumes natively: LangChain/LangGraph, CrewAI, AutoGen, Vercel AI SDK, OpenAI Agents SDK, Google ADK, Claude Desktop, Cursor, and more.

Endpoint: POST https://mcp.firstkey.io/mcp (JSON-RPC 2.0, Streamable HTTP)

Plain JSON responses, stateless (no session ids). CORS enabled (*).

Tools

Tool	What it does
`create_wallet`	Generates a fresh Ed25519 wallet (principal + PKCS#8 PEM private key). The key is returned once and never stored.
`claim_faucet_grant`	Claims the one-time free 1T cycles grant from the FirstKey faucet for an agent principal.
`deploy_site`	Creates a site canister, installs the static host, uploads files, returns the live `https:// .icp.net` URL. The agent becomes a controller of its own site. One free deploy per agent.
`deploy_upload_chunk`	Chunked upload of large files to an already-deployed agent site.
`check_cycles`	Reads a principal's cycles balance on the cycles ledger.
`get_fuel_link`	Returns the FirstKey Fuel card-payment link to refuel an agent (`https://firstkey.io/fuel?for=` ).
`get_swap_quote`	Live read-only ICPSwap quote (on-chain factory→pool): pay token/amount → receive amount + implied price. Symbols or ledger principals; no tokens move.

Quick test

URL=https://mcp.firstkey.io/mcp

initialize

curl -s $URL -H 'Content-Type: application/json' -H 'Accept: application/json, text/event-stream' \ -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"curl","version":"0"}}}' | head -c 600

list tools

curl -s $URL -H 'Content-Type: application/json' \ -d '{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}' | python3 -c "import json,sys; [print(t['name']) for t in json.load(sys.stdin)'result']"

create a wallet

curl -s $URL -H 'Content-Type: application/json' \ -d '{"jsonrpc":"2.0","id":3,"method":"tools/call","params":{"name":"create_wallet","arguments":{}}}'

Architecture

http_request (query): serves initialize, tools/list, ping, CORS preflight, /.well-known/ic-domains, and a landing page.
tools/call upgrades to http_request_update (update context) because it makes inter-canister calls: raw_rand (wallet), the faucet's claim_for (grants), the cycles ledger (balances), and the management canister (create_canister_with_extra_cycles / install_code / update_settings for deploys).
The static-site host WASM (firstkey-static-host) is embedded via include_bytes! and installed into every deployed site canister.
Deploy pool: the canister's own cycles balance. One free deploy per agent principal (tracked in stable memory); when the pool can't cover a deploy the tool returns the Fuel link instead.

Build & deploy

export PATH="$HOME/.local/bin:$HOME/.cargo/bin:$PATH"

cd ~/workspace/firstkey-static-host && cargo build --target wasm32-unknown-unknown --release cd ~/workspace/firstkey-mcp && cargo build --target wasm32-unknown-unknown --release

create (needs ~5.5T cycles on the strider identity's cycles ledger)

icp canister create -n ic --detached --cycles "5.5t" \ --controller fhvid-ondyx-ziq2v-udsry-cfgki-okcur-gcryu-2wwai-b63ku-ptgkk-yqe \ --controller o5joj-543gr-ibdnq-q6f26-sbevy-iorvz-lqo2i-ocyr7-crp2u-sggj7-cae \ --identity strider -q

install

icp canister install \ --wasm ~/workspace/firstkey-mcp/target/wasm32-unknown-unknown/release/firstkey_mcp.wasm \ -n ic --identity ops -y

authorize on the faucet

icp canister call --network ic 3l667-lyaaa-aaaam-ajkqa-cai set_mcp_canister \ --candid ~/workspace/firstkey-faucet/faucet.did --identity ops \ '(principal " ")'

Custom domain (`mcp.firstkey.io`)

DNS records needed at Porkbun (see DNS.md):

CNAME mcp.firstkey.io → mcp.firstkey.io.icp1.io
TXT _canister-id.mcp.firstkey.io →
CNAME _acme-challenge.mcp.firstkey.io → _acme-challenge.mcp.firstkey.io.icp2.io

Then validate + register:

curl 'https://icp.net/custom-domains/v1/mcp.firstkey.io/validate'

curl -X POST 'https://icp.net/custom-domains/v1/mcp.firstkey.io' curl 'https://icp.net/custom-domains/v1/mcp.firstkey.io' # poll until "registered"

The canister already serves /.well-known/ic-domains.

Registry publishing

Official MCP registry (registry.modelcontextprotocol.io): see registry/server.json (draft). Publish via GitHub OIDC from the repo's CI.
Smithery (smithery.ai/new): submit the public HTTPS URL once mcp.firstkey.io is live.

Faucet counterpart

claim_for(agent) lives on the faucet canister (3l667-lyaaa-aaaam-ajkqa-cai, source ~/workspace/firstkey-faucet/). It enforces the once-per-principal rule against the *agent* principal and performs the standard 1T ledger grant. Only the principal set via set_mcp_canister (controller-only) may call it.
