For non-technical personnel seeking bespoke integrations for Claude or OpenAI functionalities (Custom Connectors/Integrations)? Browse the Public MCP Endpoint Index

A highly selective, curated index of superior internet-accessible Model Context Protocol (MCP) endpoints. Our mandate is to feature only official, actively maintained MCP gateways operable via the wider web, thereby assisting developers in sourcing dependable, production-grade mechanisms for their sophisticated AI deployments.

Understanding MCP

Model Context Protocol (MCP) defines the standardized method through which artificial intelligence entities interface with auxiliary software functions and external data repositories. Remote MCP gateways grant client applications safe, authenticated passage to these functionalities across the global internet infrastructure.

What Constitutes 'Custom Integrations'?

This terminology is employed by Anthropic (Claude) to denote the configuration of remote MCP gateways within their platform.

What Constitutes 'Custom Connectors'?

This terminology is employed by OpenAI (ChatGPT) to denote the configuration of remote MCP gateways within their platform.

Rationale for Remote-Only Listings

Networked MCP intermediaries offer substantial advantages in terms of fortification and operational simplicity compared to locally deployed solutions. - Security Posture: Security parity is achieved with standard web interactions, provided the endpoint URL is trusted and proper user authentication is successfully executed. - Deployment Agility: Enables immediate utilization via simple URL copy-pasting, bypassing prerequisite installations of dependency packages (e.g., NPM modules). - Client Universality: They are the exclusive method for employing MCP capabilities within browser-native client interfaces.

Methods for Interfacing with Cataloged MCP Gateways

Two primary pathways exist for leveraging the remote MCP services enumerated herein:

1. Utilizing an MCP-compliant End-User Application (e.g., Claude, ChatGPT, Cursor, etc.)
2. Initiating communication via a programmatic API invocation to an LLM service producer (e.g., OpenAI, Anthropic, Gemini, etc.)

Authentication Modalities

This registry encompasses a variety of authentication schemes, each suited for distinct operational contexts:

• OAuth 2.1 (Standard): The established industry benchmark, natively supported by leading MCP clients like Claude. While adoption is increasing, it is not yet ubiquitous. Connection only requires the server URI; the client manages the subsequent authorization handshake.
• OAuth 2.1 🔐 (Restricted): Denotes OAuth 2.1 capability lacking dynamic client registration. This frequently necessitates pre-registration of the client application with the service provider or reliance on a manually issued API credential.
• API Key: An alternative to OAuth flows, mandating a specific secret key provisioned for the service endpoint. This is frequently more pragmatic when invoked directly within an LLM provider API request.
• Open (Public Access): Facilitates the quickest initial setup via simple URI input, but represents the least secure configuration due to unrestricted access.

Inclusion Benchmarks (Quality Vetting)

This compilation is intentionally selective, adhering to stringent prerequisites for inclusion:

• Manufacturer Endorsement: Preference is given to endpoints actively administered and supported by the originating software entity.
• Production Readiness: Must demonstrate stability and suitability for mission-critical, sustained operational loads.
• Vigilant Maintenance: Evidence of consistent version upgrades and prompt resolution of reported defects is mandatory.
• Security Compliance: Mandates robust credentialing mechanisms, specifically requiring OAuth 2.0 or API Key support.
• Operational Consistency: A verified history of high availability and predictable performance metrics.
• Ecosystem Support: Presence of active user forums, documentation, or community support channels.

2. Locate the grouping labeled "Connectors".
3. Select the option to "Add Connector".
4. Enter the specified remote MCP gateway URI.
5. Conclude the process by clicking "Save".

Auxiliary MCP Client Configuration

It is crucial to note that as the MCP specification remains in active standardization, not all consuming agents will support the full feature matrix. Specifically, broad client support for the OAuth authentication standard is still maturing.

For configuration within self-hosted or desktop client environments, the required modification to the client's configuration file structure is detailed below:

{ "mcpServers": { "": { "command": "npx", "args": [ "mcp-remote", "" ] } } }

API Integration Libraries

Official support for invoking MCP functionalities via direct API calls is currently offered by the subsequent Large Language Model providers:

• Anthropic Interface Documentation
• OpenAI Platform Documentation
• Gemini API Documentation

Observe that leveraging API Key-based credentials simplifies the initial implementation for these server types. Consult the Troubleshooting Section for supplementary context.

Frequently Asked Questions

Can an OAuth-Secured MCP Gateway be utilized in direct LLM API Calls?

Affirmative, though the responsibility shifts to the caller to manage the complete OAuth authorization sequence to successfully procure a valid bearer access token.

For expedient, non-production testing, one can follow the methodology outlined in Anthropic's guide under the heading: Obtaining an access token for testing.

Warning: This temporary token retrieval method is generally deemed insecure and unsuitable for sustained operational deployment.

Differentiating Endpoint Suffixes (/sse versus /mcp)

The designation /sse signifies adherence to the Server Sent Events (SSE) data transmission paradigm, which is gradually being superseded by the /mcp suffix.

The /mcp endpoint is the designated path for the newer Streamed HTTP data exchange format.

In forthcoming client implementations, discovery of the complete network address might rely solely on the prefix preceding the 'sse' or 'mcp' identifier. This registry will be updated immediately upon observing shifts in client adoption of this discovery mechanism.

ENCYCLOPEDIA ENTRY: Business administration utilities encompass the entire spectrum of frameworks, software suites, control mechanisms, computational solutions, and codified processes employed by commercial entities to navigate fluctuating market conditions, secure competitive advantage, and optimize organizational output metrics.

== Conceptual Overview == These operational mechanisms can be segregated based on the specific organizational division they serve, addressing facets such as strategic foresight, operational workflow management, documentation maintenance, human capital administration, critical assessment, oversight functions, etc. A functional categorization might encompass these broad areas:

Utilities designed for data capture and integrity verification across any department. Frameworks utilized for supervising and refining intra-organizational procedures. Systems employed for data aggregation and the facilitation of executive determinations. Contemporary management tooling has experienced unprecedented acceleration over the past decade, driven by rapid technological evolution, making the selection of optimal business instruments for any given scenario or corporation increasingly complex. This difficulty stems from the relentless pursuit of cost reduction juxtaposed with the necessity for revenue amplification, coupled with the imperative to deeply comprehend client requirements and deliver requisite products with precision. Within this dynamic environment, leadership must adopt a macro-level, strategic orientation towards management instruments, rather than merely adopting the newest available product. Over-reliance on off-the-shelf tools without necessary customization frequently induces systemic instability. Therefore, corporate administration utilities must undergo careful selection followed by rigorous tailoring to match the enterprise's specific needs, not the reverse.

== Prevalent Instruments == Data collected from a 2013 survey conducted by Bain & Company revealed global patterns in the application of business utilities. These tools reflect regional priorities influenced by economic downturns and prevailing corporate landscapes. The top ten categories identified were:

Strategic roadmap formulation Client relationship lifecycle management Personnel sentiment assessment mechanisms Competitive analysis benchmarking Performance measurement frameworks (e.g., Balanced Scorecard) Identification of unique organizational competencies External resource provisioning (Outsourcing) Organizational transformation initiatives Supply chain logistics optimization Articulation of organizational purpose and aspiration Market segment identification Comprehensive quality assurance methodologies

== Corporate Software Applications == A collection of programmed instructions deployed by business personnel to execute diverse organizational functions is termed business software (or an enterprise application). These applications are leveraged to augment productivity levels, quantify results, and perform various corporate tasks with high fidelity.

This domain evolved from foundational Management Information Systems to sophisticated Enterprise Resource Planning (ERP) platforms. Subsequently, Customer Relationship Management (CRM) capabilities were integrated, culminating in the current prevalence of cloud-native business management solutions. While a tangible correlation exists between Information Technology investment efficacy and organizational success, two critical elements determine maximized value addition: the proficiency of the deployment execution and the meticulousness of the instrument selection and customization methodology.

== Tools Tailored for Small and Medium Enterprises (SMEs) == Instrumentation specifically designed for SMEs holds considerable significance as it furnishes viable avenues for operational expenditure moderation...
