mcp.run

Best for Developers building AI agents with MCP tools

mcp.run is a hosted registry and marketplace for Model Context Protocol servers and tools, allowing developers to discover, install, and share reusable MCP "servlets" that extend AI applications with new capabilities. It provides a catalog of community and vendor-published tools, along with mechanisms for versioning and permissioning installed servers. The platform targets developers building AI agents or assistants who want a centralized way to find and manage MCP-compatible tools rather than building integrations from scratch, reducing duplicated setup work across projects.

• Tool discovery registry
• Servlet installation management
• Versioning and permissions

Composio

composio.dev

Best for Developers building AI agents needing app integrations·Free trial

Composio is a platform that provides pre-built integrations and tool connections for AI agents, enabling them to interact with external applications such as email, calendars, CRMs, and developer tools. It supports the Model Context Protocol (MCP) alongside other agent frameworks, offering managed authentication and a library of ready-made actions so developers can connect large language models to third-party services without building integrations from scratch. It suits engineering teams building AI agents or assistants that need reliable, maintained access to multiple external APIs.

• Pre-built tool integrations
• MCP protocol support
• Managed authentication

3

Pipedream

Free plan

pipedream.com

Best for Developers building custom API integrations and agents

Pipedream is a workflow automation platform that lets developers build integrations and API workflows using serverless code steps alongside prebuilt actions and triggers. It supports connecting to thousands of APIs and includes tooling for exposing workflows and integrations as MCP servers, enabling AI agents to call external tools and services. The platform suits developers and technical teams building custom automations, internal tools, or agent-based systems who want flexibility to mix code with managed integrations.

• Serverless workflow steps
• Prebuilt API integrations
• MCP server hosting

4

Model Context Protocol

Free plan

modelcontextprotocol.io

Best for Developers building AI apps needing tool/data integrations

Model Context Protocol (MCP) is an open standard that defines how AI applications connect to external data sources, tools, and systems through a unified interface. Instead of building custom integrations for each data source, developers can implement MCP servers that expose resources, tools, and prompts to compatible AI clients. Maintained as an open specification with SDKs in multiple languages, it supports use cases such as connecting AI assistants to databases, file systems, APIs, and business applications. It suits developers and organizations building or integrating AI applications that need standardized, reusable connections to external context.

• Standardized client-server protocol
• Multi-language SDKs
• Resource, tool, and prompt exposure

5

Glama

glama.ai

Best for Developers building AI apps with MCP integrations

Glama is a platform for discovering, hosting, and monitoring MCP (Model Context Protocol) servers. It provides a directory of available MCP servers that developers can browse and connect to, along with tools for inspecting server behavior and managing deployments. The platform is aimed at developers and teams building AI applications that rely on MCP to connect language models with external tools and data sources, offering a central place to evaluate and integrate available servers rather than searching across scattered repositories.

• MCP server directory
• Server hosting
• Monitoring and inspection tools

6

OpenTools

Free plan

opentools.com

Best for Developers building AI agents with MCP

OpenTools is a directory and marketplace for Model Context Protocol (MCP) servers, allowing developers to browse, search, and discover tools and integrations that can be connected to AI applications and agents. It provides listings of available MCP servers along with setup information, helping users find connectors for specific data sources, APIs, or services. The platform is aimed at developers and teams building AI agents who need to locate and evaluate MCP-compatible tools rather than build integrations from scratch.

• MCP server directory
• Search and discovery
• Integration setup guidance

PulseMCP

pulsemcp.com

Best for Developers building AI agents with MCP integrations

PulseMCP is a website that tracks and catalogs Model Context Protocol (MCP) servers, clients, and related tools. It provides a searchable directory of available MCP servers along with news, updates, and use-case examples for the emerging MCP ecosystem. The site helps developers discover existing servers before building new ones and stay informed about protocol changes and community projects. It suits developers and teams working with AI agents and large language models who need to find or evaluate MCP integrations rather than build tooling from scratch.

• MCP server directory
• Ecosystem news updates
• Use-case examples
