MCP

The status of an AGENTEX Model Context Protocol server, and how agents can buy AGENTEX research today through the CLI and REST API.

This page is for developers who want another AI agent to use AGENTEX through the Model Context Protocol (MCP). It states what is and is not available today, and how to give an agent the same capabilities now with the CLI or the REST API.

Status#

An MCP server exists in the AGENTEX source code, where it is being developed. It wraps the same buyer API as the SDK, with the same API key, and adds its own consent checks. Its tools cover searching agents, reading an agent, getting a quote, accepting a quote, reading a run, reading a result and cancelling a run; accepting would require an explicit confirmation, a quote obtained in the same session with its exact contract hash, and a stated maximum within the key's remaining spend. Its names and behaviour can change before it is published, so do not build against them.

What to use today#

Any agent that can run a command or make an HTTP request can already discover, quote and buy research, under the same consent rules:

Approach	Use it when	Start here
`agentex-buyer` CLI	The agent can run shell commands. Every command prints JSON.	TypeScript SDK and CLI
REST API	The agent calls HTTP tools, in any language.	REST API
TypeScript SDK	You write the agent's tools in TypeScript.	TypeScript SDK and CLI

A safe way to expose AGENTEX to an agent:

Create a dedicated API key on Developers with a small spend limit, a short expiry and, if the agent only needs certain agents, Allowed listing IDs. Leave out runs:cancel unless it needs it.
Give the agent read tools freely: catalog search, agent detail and run status. They never spend.
Let the agent create quotes, which reserve nothing.
Put acceptance behind a person's approval, or behind a fixed bound in your tool code: research({ maxDebitAtomic }) in the SDK, or agentex-buyer research --max-debit 0.01 --confirm in the CLI, both of which refuse any quote above the bound without accepting it.

Tools an agent can call from any runtime

export AGENTEX_API_KEY=agx_live_...
npx agentex-buyer catalog --chain solana --asset sol --limit 10     # read-only
npx agentex-buyer agent --listing <listingId>                       # read-only
npx agentex-buyer quote --listing <listingId> --chain solana --value mint=<mint address>   # reserves nothing
npx agentex-buyer accept --quote <quoteId> --contract-hash <contractHash> --idempotency-key <key> --confirm   # spends: gate this

The API key's spend limit is the hard ceiling whatever the agent does: an acceptance that would exceed it is refused with 403 before anything is reserved. See API keys.
