apiosk-mcp 1.3.0

PyPI launcher for the official Apiosk MCP server

Apiosk MCP Server

Official MCP server for discovering, paying for, and publishing Apiosk APIs.

Quick Start

Package names

The scoped npm package is the canonical client SDK package:

npm install @apiosk/mcp

It exposes the same CLI binaries as the legacy package:

npx -y @apiosk/mcp
apiosk-mcp
apiosk-mcp-server
apiosk

The previous public package name, apiosk-mcp-server, remains supported as a compatibility install path for existing MCP client configs.

For MCP registry submission forms, use:

• npm Package: @apiosk/mcp
• PyPI Package: apiosk-mcp
• Short Description: Discover, pay for, execute, and publish Apiosk APIs through MCP.

The PyPI package is a launcher for the canonical npm package, so uvx apiosk-mcp starts the same MCP server as npx -y @apiosk/mcp.

Local stdio package

npx -y @apiosk/mcp

Python/uv users can install through PyPI:

uvx apiosk-mcp

The PyPI launcher requires Node.js 20+ and npx on PATH. By default it runs npx -y @apiosk/mcp@1.3.0; set APIOSK_MCP_NPM_PACKAGE=@apiosk/mcp@next to override the npm package spec.

Publishing packages

From this mcp/ directory:

npm run pack:check
npm publish --access public

python3 -m pip install --upgrade build twine
python3 -m build
python3 -m twine upload dist/apiosk_mcp-1.3.0*

After both uploads are live, the MCP registry package fields are:

npm Package: @apiosk/mcp
PyPI Package: apiosk-mcp
Short Description: Discover, pay for, execute, and publish Apiosk APIs through MCP.

With automatic x402 payments from an env wallet

APIOSK_PRIVATE_KEY=0x... npx -y @apiosk/mcp

With dashboard-managed access

APIOSK_CONNECT_TOKEN=... npx -y @apiosk/mcp

After the MCP server is installed in Claude, Codex, or another client, the fastest first-run path in local stdio mode is:

{ "wallet_label": "My Apiosk wallet" }

Call that through apiosk_get_started. It will create a local wallet when needed, or you can pass connect_string to save managed access locally and immediately run a discovery probe plus a small test call.

Local Wallet Mode

The local stdio package exposes wallet tools that let Claude or Codex:

• create or import a wallet
• show the wallet address
• select the active wallet used for paid calls
• reveal or save the private key when the user explicitly asks
• publish and manage APIs without opening the dashboard

The active wallet is mirrored to:

• ~/.apiosk/wallet.json
• ~/.apiosk/wallet.txt

so older Apiosk scripts can reuse it.

ChatGPT and other remote MCP apps

Use the hosted MCP endpoint:

https://mcp.apiosk.com/mcp

Protected tools on the hosted server use OAuth. The remote MCP surface is fully capable — discovery, payment guidance, generic and dynamic per-API execution, prepaid credits, and managed agent-wallet CRUD. Public tools (discovery + guidance) work before authorization; paid execution and managed tools require OAuth. Publishing stays local/portal-only because it needs a client-side signing key the hosted server never holds.

Provider MCP Monetization

If you own an MCP server and want to sell its tools through Apiosk, keep payment logic out of your MCP. Apiosk is the paid edge.

Provider requirements:

• Host your MCP over HTTPS, for example https://tools.example.com/mcp.
• Support normal MCP initialize, tools/list, and tools/call.
• Keep tool names stable; imported tools become paid operation ids.
• Provide useful descriptions and JSON schemas; these become buyer-facing discovery metadata.
• Protect the provider MCP with bearer auth or another upstream secret, then configure Apiosk to inject that secret so buyers cannot bypass the gateway.

Provider portal flow:

1. Open the provider portal and choose Import MCP.
2. Enter the MCP URL and optional bearer token.
3. Apiosk scans tools/list and creates one paid action per selected tool.
4. Review tool paths, schemas, descriptions, and per-call prices.
5. Publish the draft after linking a payout wallet.

Buyer-facing surfaces after publish:

• Hosted Apiosk MCP: https://mcp.apiosk.com/mcp
• Catalog search: https://gateway.apiosk.com/v1/apis?search=<slug>
• Metadata: GET https://gateway.apiosk.com/<slug>/metadata
• Execution: POST https://gateway.apiosk.com/<slug>/execute

The traffic path is:

buyer agent -> Apiosk MCP/gateway -> payment rail -> provider MCP tools/call

The provider MCP should reject direct unauthenticated traffic, but it should not return 402 Payment Required or inspect X-Payment. Payment challenges, credits, x402 proof verification, and revenue splits are handled by Apiosk.

Available Tools

Static tools:

• apiosk_help
• apiosk_payment_guide — buyer + provider guide for paying through and publishing on the gateway

Dynamic tools:

• local stdio mode still generates one dynamic tool per active Apiosk API slug from listing metadata

Examples

Explore

{}

{ "listing_type": "dataset", "search": "weather", "limit": 5 }

Search

{ "search": "diff", "limit": 5 }

Search, explore, and apiosk_get_api responses now embed a payment block that tells the agent exactly how to settle a paid call given the current auth — so an agent that finds, say, a weather API immediately knows whether it can pay and what to do next.

Payment guide (buyer + provider)

{}

{ "role": "provider" }

{ "role": "buyer", "slug": "weather-now" }

Returns a buyer guide (USDC/x402 or credits — tailored to the configured auth) and a provider guide (how to publish an API and get paid). Pass slug to scope buyer guidance to one listing, or role to pick a side.

Create a local wallet

{ "label": "Claude wallet" }

The create response includes:

• the wallet address
• Base funding instructions
• a QR image URL
• a terminal QR block when QR rendering is enabled
• a structured Apiosk control menu with wallet, funding, pay, publish, security, and local-data sections

Get started in one step

Create a local wallet automatically, discover the catalog, and run a test call:

{
  "wallet_label": "Starter wallet",
  "test_slug": "agent-json-diff",
  "test_input": {
    "before": { "ok": true },
    "after": { "ok": false }
  }
}

Or save a dashboard-managed connect string locally and verify it:

{
  "connect_string": "export APIO_GATEWAY_URL=https://gateway.apiosk.com\nexport APIO_CHAIN_ID=8453\nexport APIO_AGENT_WALLET_ADDRESS=0x...\nexport APIO_CONNECT_TOKEN=aw_...\nexport APIO_CONNECT_AUTHORIZATION=Bearer aw_...\nexport APIO_CONNECT_HEADER_NAME=X-Apiosk-Connect-Token",
  "test_slug": "agent-json-diff",
  "test_input": {
    "before": { "ok": true },
    "after": { "ok": false }
  },
  "create_wallet": false
}

The connect string identifies the buyer's managed wallet and connect token. The APIO_WALLET_* limits bound the USDC (x402) rail. The same connect token also settles over prepaid credits when USDC is unavailable — the gateway picks the rail per call. Call apiosk_help with topic="rails" for the full settlement model.

Open the configure menu

{ "section": "funding" }

{ "wallet_id": "...", "section": "funding", "funding_provider": "onramper" }

Save a secret key backup

{ "wallet_id": "..." }

Publish an API

{
  "name": "My Weather API",
  "slug": "my-weather-api",
  "endpoint_url": "https://example.com",
  "price_usd": 0.01,
  "description": "Real-time weather data",
  "listing_group": "datasets"
}

Generic execute

{
  "slug": "agent-json-diff",
  "input": {
    "before": { "ok": true },
    "after": { "ok": false }
  }
}

Dynamic tool call (local stdio only)

If the server lists a dynamic tool named agent-json-diff, call it directly:

{
  "before": { "ok": true },
  "after": { "ok": false }
}

MacBook Air Test Script

Run the safe default suite from a repo checkout:

cd /Users/olivierbrinkman/Development/Apiosk/subs/mcp
npm run test:macbook-air

Default coverage:

• runs npm test
• runs the isolated fresh-environment smoke test
• starts a local HTTP MCP server in a temp APIOSK_HOME
• verifies health, tools/list, apiosk_search, apiosk_explore, and apiosk_get_api
• creates a wallet, checks funding QR/configure output, and verifies secret export plus wallet.json and wallet.txt
• verifies the hosted Fly deployment, OAuth metadata, protected-resource metadata, public discovery, and the unauthenticated OAuth challenge for protected tools

Useful options:

• TARGET=local to skip hosted checks
• TARGET=hosted to skip local checks
• APIOSK_RUN_REMOTE_WALLET_TEST=1 APIOSK_MCP_BEARER_TOKEN=... to verify an authenticated protected hosted call after the unauthenticated challenge check
• APIOSK_RUN_FUNDED_TESTS=1 APIOSK_TEST_PRIVATE_KEY=0x... to import a funded wallet and run a real paid execute test
• APIOSK_RUN_FUNDED_TESTS=1 APIOSK_MCP_BEARER_TOKEN=... TARGET=hosted to run a real paid execute test through the hosted OAuth path
• APIOSK_RUN_FUNDED_TESTS=1 APIOSK_RUN_PUBLISH_TEST=1 APIOSK_TEST_PRIVATE_KEY=0x... TARGET=local to also test publish, list, update, and delete with a temporary listing

Example funded run:

cd /Users/olivierbrinkman/Development/Apiosk/subs/mcp
APIOSK_RUN_FUNDED_TESTS=1 \
APIOSK_TEST_PRIVATE_KEY=0x... \
npm run test:macbook-air

Live URL Test Script

Run a hosted-only test directly against the public MCP endpoint:

cd /Users/olivierbrinkman/Development/Apiosk/subs/mcp
npm run test:live

Default live coverage:

• checks https://mcp.apiosk.com/health
• verifies the hosted tool surface
• verifies /.well-known/oauth-authorization-server
• verifies /.well-known/oauth-protected-resource/mcp
• runs live apiosk_explore, apiosk_metadata, and apiosk_health
• verifies that an unauthenticated protected MCP tool call returns the expected OAuth 401 challenge

Optional live funded checks:

• APIOSK_RUN_REMOTE_WALLET_TEST=1 APIOSK_MCP_BEARER_TOKEN=... npm run test:live
• APIOSK_RUN_FUNDED_TESTS=1 APIOSK_MCP_BEARER_TOKEN=... npm run test:live

The live hosted suite no longer imports a private key into the hosted MCP. Protected live checks now rely on a real hosted OAuth bearer token, which matches the ChatGPT-style remote MCP flow.

Environment Variables

• APIOSK_PRIVATE_KEY: enables automatic x402 settlement and signed publish requests
• APIOSK_CONNECT_TOKEN: attach a dashboard-managed connect token
• APIOSK_CONNECT_AUTHORIZATION: attach a custom Authorization header
• APIOSK_CONNECT_HEADER_NAME: override the connect-token header name
• APIOSK_WALLET_ADDRESS: send a wallet address for wallet-aware flows
• APIOSK_X_PAYMENT: attach a pre-built x402 proof manually
• APIOSK_GATEWAY: override the gateway base URL
• APIOSK_CONTROL_PLANE_URL: override the MCP-owned control-plane API base URL used for account, credits, and managed-wallet routes. Defaults to https://mcp.apiosk.com
• APIOSK_DASHBOARD_URL: override the human-facing dashboard/app URL stored in local config and used in confirmation flows. Defaults to https://dashboard.apiosk.com
• APIOSK_DASHBOARD_JWT or APIOSK_USER_JWT: unlock dashboard wallet routes
• APIOSK_ENABLE_LOCAL_WALLETS=true: enable local wallet tools in HTTP server mode
• APIOSK_MCP_OAUTH_SECRET or APIOSK_MCP_AUTH_SECRET: signing secret for hosted OAuth codes, access tokens, and refresh tokens
• APIOSK_MCP_BEARER_TOKEN: optional hosted OAuth access token used by the live scripts for authenticated protected-tool checks
• APIOSK_HOME: override the default ~/.apiosk directory
• APIOSK_MCP_WALLET_STORE: override the local wallet store path

Human-Funded Credits Flow

In the local stdio package, MCP can now help a human top up Apiosk credits and then let the agent spend those credits later:

1. apiosk_create_account if the user needs a new Apiosk account
2. apiosk_sign_in to store a local dashboard session token
3. apiosk_buy_credits to create an Adyen checkout link
4. apiosk_get_credits_status after payment to reconcile the top-up and confirm the balance

If signup does not return a session immediately, tell the user to confirm their email first and then call apiosk_sign_in.

These calls now target the MCP-owned control-plane surface by default:

• https://mcp.apiosk.com/api/auth/mcp-sign-up
• https://mcp.apiosk.com/api/auth/mcp-sign-in
• https://mcp.apiosk.com/api/credits/topup
• https://mcp.apiosk.com/api/credits/reconcile

Remote HTTP Server

The public HTTP deployment is safe-by-default: local wallet and publish tools are disabled unless APIOSK_ENABLE_LOCAL_WALLETS=true is set on that server.

Hosted OAuth metadata and authorization routes now live on the same host:

• https://mcp.apiosk.com/.well-known/oauth-authorization-server
• https://mcp.apiosk.com/.well-known/oauth-protected-resource/mcp
• https://mcp.apiosk.com/authorize
• https://mcp.apiosk.com/token
• https://mcp.apiosk.com/register

Test it:

curl https://mcp.apiosk.com/health

curl https://mcp.apiosk.com/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Development

npm install
npm run dev    # HTTP server on :3000
node index.mjs # stdio mode with local wallet tools enabled

Fresh-environment smoke test:

cd /Users/olivierbrinkman/Development/Apiosk/subs/mcp
npm run smoke:new-env
