Primary tools included: Pay-per-call MCP APIs settled on Kaspa, Text transformation and schema-based extraction, Web reading, embeddings, and semantic search.
Agent-payable APIs settled on Kaspa L1: text tools (summarize, schema-guaranteed extract, classify, rewrite), web reading, embeddings + semantic search, live Kaspa chain data, GPU LLM tiers, covenants-as-a-service, and RISC Zero zk proving with cycle-exact quotes. Pay per call in KAS, BTC, LTC, DOGE, BCH, DASH, ETH, or USDC — fractions of a cent, no account or API key. pip install k402-mcp

Dodo Agent Plugin Tools (2)
execute
Runs JavaScript code to interact with the Dodo Payments API.
You are a skilled TypeScript programmer writing code to interface with the service.
Define an async function named "run" that takes a single parameter of an initialized SDK client and it will be run.
For example:
```
async function run(client) {
const checkoutSessionResponse = await client.checkoutSessions.create({ product_cart: [{ product_id: 'pdt_example', quantity: 1 }] });
console.log(checkoutSessionResponse.session_id);
}
```
You will be returned anything that your function returns, plus the results of any console.log statements.
Do not add try-catch blocks for single API calls. The tool will handle errors for you.
Do not add comments unless necessary for generating better code.
Code will run in a container, and cannot interact with the network outside of the given SDK client.
Variables will not persist between calls, so make sure to return or log any data you might need later.
Remember that you are writing TypeScript code, so you need to be careful with your types.
Always type dynamic key-value stores explicitly as Record<string, YourValueType> instead of {}.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
K402 MCP is categorized under Finance & Fintech and uses a local stdio subprocess. In contrast, Dodo Agent Plugin belongs to Finance & Fintech using local stdio subprocess. Select K402 MCP when you need capabilities focused on finance & fintech and Dodo Agent Plugin when you require tools for finance & fintech.
Official Dodo Payments MCP servers — dodopayments-api for live payments, subscriptions, customers, products, refunds, license keys, and usage-based billing (browser OAuth, no API key needed) and dodo-knowledge for semantic search over Dodo Payments documentation.
Search SDK documentation to find methods, parameters, and usage examples for interacting with the API. Use this before writing code when you need to discover the right approach.
