Connect Munition to your AI app

Munition is a remote MCP server: paste one URL, approve once, use the tools. No sign-up, no API key, no install.

https://api.munition.io/mcp

Transport: MCP Streamable HTTP. Auth: OAuth 2.1 (PKCE S256, Client ID Metadata Documents or Dynamic Client Registration). The first time you connect, Munition shows a one-screen consent page; one click creates an anonymous Munition account for your browser and connects the app. Reconnecting from the same browser reuses the same account and balance.

1. Open Settings → Connectors → Add custom connector (Team/Enterprise: an owner adds it under Organization settings → Connectors).
2. Name: Munition. URL: https://api.munition.io/mcp. Leave the OAuth client fields empty.
3. Click Connect, then Create my Munition account & connect on the Munition page.
4. In a chat, enable the Munition tools from the tools menu and ask, for example: "Search the web with Munition for recent x402 news and summarize the top 3 sources."

Claude Code

Then run /mcp in Claude Code, pick munition and authenticate in the browser.

ChatGPT (developer mode)

Settings → Apps & Connectors → Advanced → enable Developer mode, then Create a connector with URL https://api.munition.io/mcp and OAuth authentication. Availability of write-capable connectors depends on your ChatGPT plan.

Codex CLI

codex mcp add munition --url https://api.munition.io/mcp
codex mcp login munition

Cursor and other MCP clients

Add a remote (HTTP) MCP server with URL https://api.munition.io/mcp; the client opens the OAuth consent page on first use. Clients that only support local stdio servers can keep using npx -y @munition/mcp (see https://munition.io/skill.md).

Tools and prices

Free: catalog (list tools and prices), balance, topup_link, get_run (receipt of a paid call), flight_booking_links.

Paid, fixed price per call, charged to your Munition balance (USDC, 1 USDC = $1):

Tool	Price
airports_search	$0.001
web_contents	$0.002
google_search, google_news, google_images, google_shopping	$0.004
web_search, web_find_similar, web_answer, flight_offer_details	$0.01
web_scrape	$0.015
render_pdf	$0.02
web_search_scrape	$0.03
search_flights	$0.05

Every paid result includes a run block with receipt links and the on-chain transaction on Base.

Adding funds

New accounts start at $0. When a paid tool needs funds, it returns a one-click top-up link (valid 15 minutes) instead of failing: open it, add funds by card (onramp; availability varies by country) or send USDC on Base, then ask the agent to retry. You can also ask for the topup_link tool at any time. Munition charges no top-up fee.

Already using @munition/mcp locally?

To use the same account and balance in Claude.ai or ChatGPT, ask your local agent to run the connect_link tool (@munition/mcp 0.0.16+), open the link it returns in the browser you will connect from, confirm, then add or reconnect the connector.

Security

• Tokens are short-lived (1 hour) and refreshed with rotating refresh tokens; Munition stores only hashes.
• Each connection is a separate grant; access tokens only work on https://api.munition.io/mcp.
• Paid tools are annotated as spending tools so your app asks before calling them.
• Support: hello@munition.io
