Intent
The agent identifies a bounded action needed to complete the task.
Connect agents to tools without surrendering control.
Model Context Protocol can give an agent structured access to files, browsers, databases, and business systems. The training focuses on tool contracts, least privilege, failure behavior, and the evidence needed before an integration touches live work.
Trace the complete tool call
Schema
The tool description and input shape make valid use unambiguous.
Permission
Credentials and scopes allow only the required resource and action.
Result
Structured output separates data, errors, and retryable conditions.
Evidence
Logs record what ran without leaking secrets or private payloads.
Use MCP when it earns the complexity
| Need | Prefer | Reason |
|---|---|---|
| One stable request in one app | Existing API or CLI | Fewer moving parts and easier failure diagnosis. |
| Reusable tools across agent clients | MCP server | A shared schema and transport can serve more than one agent workflow. |
| Destructive or high-risk action | Approval-gated tool | The human must see the intended target and consequence before execution. |
| Read-only discovery across sources | Scoped MCP tools | Structured access can reduce copy-paste while keeping source attribution. |
Integration lab
Build a read-first research tool
The exercise favors a reversible workflow so you can learn server configuration, schemas, auth, and observability before enabling writes.
- Define one search tool and one item-detail tool.
- Restrict credentials to a test workspace or read-only scope.
- Return source IDs, timestamps, and explicit error types.
- Test empty results, malformed input, rate limits, and offline startup.
- Add one approval gate before any future write operation.
Bring one integration and its permission boundary.
Builder includes the complete MCP track. Operator is the reviewed route when the integration belongs inside a production-agent capstone.
