# MCP tools

> Planning reference for public tools exposed by The Blockchain Library MCP Server.

## Tool design principles

Each tool should have:

* A narrow purpose.
* Explicit inputs.
* Predictable outputs.
* Safe failure behavior.
* Clear data-use expectations.
* Documentation and examples.

## Candidate tools

| Glossary      | Define a blockchain term             |
| Learning      | Recommend the next learning resource |
