MCP Tool Directory Index

A searchable, verifiable directory of MCP tools with call examples

Problem

The MCP ecosystem is exploding, but developers struggle to discover available tools, their capabilities, and how to call them; existing lists are scattered and lack standardized validation and examples.

Solution

An MCP tool directory site: lists tools, search by capability/use-case/model compatibility, shows standardized call examples and schemas, and supports submissions and community voting. Can expand into an online tool-call sandbox for single invocations.

Users

Developers building AI agents, MCP server maintainers, AI tool integrators

MVP

Ingest MCP tools with structured metadata (name, description, param schema, author); keyword and tag search; each tool page shows call examples and installation; open submission and simple voting; periodic GitHub scraping to keep listings fresh.

Revenue

Free browsing; paid featured/boosted listings; private directories and compliance audits for enterprises; usage-based API access.

Why now

MCP is becoming the de facto standard for AI agent tool integration, and discovery needs are growing while current resources are fragmented; directories are lightweight and incremental, ideal for indie developers.
