eSentire MCP Server

eSentire operates a Model Context Protocol server on its own API host. It was found by probe, not by documentation — eSentire publishes no developer portal and no page describing this server. The evidence is unambiguous: api.esentire.com is an AWS API Gateway that answers unrouted paths with 403 MISSING_AUTHENTICATION_TOKEN, but every path under /mcp/ answers 401 UNAUTHORIZED and carries the RFC 9728 challenge header `WWW-Authenticate: Bearer resource_metadata="https://api.esentire.com/.well-known/oauth-protected-resource"`. That header is the Model Context Protocol authorization pattern verbatim, and the resource-metadata document it names resolves and points back at the same host. Authorization is Okta-backed OAuth 2.0 authorization code with PKCE (S256), and RFC 7591 dynamic client registration is open anonymously at https://api.esentire.com/register.

Connect

This is a remote MCP server — point an MCP client at the endpoint URL. Clients with native remote support (Claude, Cursor, VS Code, …):

# mcp client config (e.g. .mcp.json / mcp settings) { "mcpServers": { "esentire": { "url": "https://api.esentire.com/mcp" } } }

For stdio-only clients (older Claude Desktop, etc.), bridge with mcp-remote:

# Add to claude_desktop_config.json { "mcpServers": { "esentire": { "command": "npx", "args": ["-y", "mcp-remote", "https://api.esentire.com/mcp"] } } }

If the server requires authentication, add the provider's token/header (e.g. an X-API-Key) per its docs. A quick reachability check:

curl -i -X POST https://api.esentire.com/mcp \ -H "Content-Type: application/json" -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

About MCP

The Model Context Protocol (MCP) is an open protocol Anthropic introduced for connecting LLM-based agents to external tools and data sources. Providers publish MCP servers that expose their API surface as structured, discoverable tools — an MCP-compatible client (Claude Desktop, Cursor, Cline, Continue, etc.) can connect to the server and call its tools without any per-provider integration code.

Browse every MCP server on the APIs.io network or compare with the broader Agent Skill surfaces of the same providers.

Work with this as data

Every MCP server here is available over the APIs.io API and to AI agents over MCP.
