Build an MCP Agent with Explicit Tools and Controls

Define tools, permissions, schemas, tests, and human controls for a reviewable Model Context Protocol agent.

Start with an MCP Agent Brief

Choose a sample or describe your MCP agent, then continue in MiniMax Code.

Turn an Integration Plan into a Reviewable MCP Agent

Keep planning, creation, review, and handoff connected in one clear workflow.

Tool Contracts

Define Narrow, Typed Capabilities

Specify tool names, input and output schemas, validation, errors, timeouts, and safe limits before implementation.

Illustrative workflow for define narrow, typed capabilities.

Access Control

Keep Permissions Explicit

Separate authentication from authorization, minimize scopes, protect secrets, and record which identity performed each action.

Evaluation & Oversight

Test Behavior before Expansion

Evaluate success, refusal, failure, injection resistance, logging, and human approval across representative cases.

Keep the Entire Workflow Connected

A workflow comparison, not a performance benchmark. Important facts and final results still need human review.

Build an MCP Agent in Four Steps

Start with a focused brief, create a reviewable draft, and validate the result before delivery.

  1. Step.01

    Define the Agent Boundary

    State the users, goals, allowed systems, prohibited actions, risk level, and human approval requirements.

    MCP Agent workflow, step 1: Define the Agent Boundary.
  2. Step.02

    Design MCP Tools and Schemas

    Specify narrow tools, typed inputs and outputs, authentication, authorization, validation, and errors.

    MCP Agent workflow, step 2: Design MCP Tools and Schemas.
  3. Step.03

    Implement and Test Locally

    Build the server and client workflow, use test credentials, exercise success and failure cases, and inspect logs.

    MCP Agent workflow, step 3: Implement and Test Locally.
  4. Step.04

    Evaluate and Deploy Carefully

    Run security and behavior evaluations, document operations, protect secrets, and expand access only after review.
