The Model Context Protocol (MCP) is the format for that. The servers in this registry don't exist alongside the APIs, they're built from them. If you know the [APIs](https://nexora.apim.eu/apis), you'll find the same operations here - just as a tool instead of an endpoint. What applies to the API catalog therefore applies here too: the same error format, the same authentication, the same permissions. The **Kong AI Gateway** sits in front either way. It decides who may call which server and which tool, logs every call, and keeps the tool list current. ## [MCP Servers for Developers](#mcp-servers-for-developers) This list comes directly from the Konnect MCP registry `nexora-ai-ops`. It always shows the published state - when a server is added, it appears here without this page needing to change.

Each entry is reachable at its path on the gateway. | Server | Path | Tools | | :---------------------------- | :----------------------- | :--------------------------------------------------------------------------- | | Agent Deployments | /mcp/agent-deployments | list-agentsget-agentregister-agentupdate-agentlist-agent-artifacts | | Access & Onboarding Requests | /mcp/access-requests | list-requestsget-requestlog-requestget-request-scorematching-agents | | Evaluation Sessions | /mcp/evaluation-sessions | list-sessionscreate-sessionreschedule-sessionavailable-timeslotslog-feedback | | Cost & ROI Estimation | /mcp/cost-estimation | request-estimateget-estimatequery-comparablesquery-usage-index | | Usage Chargeback & Settlement | (tool library) | list-settlementsget-settlementcalculate-chargeback | **Usage Chargeback & Settlement** is deliberately set up without its own endpoint. It serves as a library that other servers draw their tools from - settlement data shouldn't accidentally end up on an open endpoint. ## [Connected Third-Party Systems](#connected-third-party-systems) These servers already speak MCP. The gateway passes them through unchanged and adds access control and logging. | Server | Path | What it's for | | :---------------------- | :-------------------------- | :-------------------------------------------------------------------------- | | Pricing Benchmark Index | /pricing-benchmark-index | External index of LLM/agent unit-cost benchmarks by provider and model tier | | Model Registry Extract | /mcp/model-registry-extract | Provenance and lineage records for third-party foundation models | | Compliance Registry | /mcp/compliance-registry | External regulatory and compliance policy lookups | Third-party systems get the same access control as Nexora AI's own servers. A key that isn't allowed to see model-provenance data doesn't even get that tool shown in its list. From the Spec, Not Beside It The back-office tools are generated from the same OpenAPI specifications that feed the API catalog. When an endpoint changes, the tool changes with it - there's no second description that can drift out of date. Permissions per Tool Access is controlled not just per server, but per tool. A read-only key gets `list-agents` but not `update-agent` - and sees the difference right in the tool list. Every Call Is Traceable The gateway logs which key called which tool when, and with what result. For an agent that decides on its own, that's not a nice-to-have, it's the prerequisite. **Access:** MCP servers are called with the same API key as the other interfaces. To learn how to generate a key, see [Authentication](https://nexora.apim.eu/guides/authentication). The gateway's base address depends on the environment - the paths above stay the same across all environments. ## [Server Operating Modes](#server-operating-modes) An MCP server in the gateway is always one of several operating modes. Three of them are in use for Nexora AI: | Mode | What it does | In use here | | :------------------- | :----------------------------------------------------------------- | :---------------------------- | | conversion-listener | Translates a REST API into tools and accepts MCP requests | The four back-office systems | | conversion-only | Translates a REST API into tools without being reachable itself | Usage Chargeback & Settlement | | passthrough-listener | Passes a third-party MCP server through without changing its tools | The three third-party systems | If you want to rebuild the servers yourself, the full declarative configuration is in the repository under `ai-gateway/config/mcp-servers.yaml`. ## Ready for Your First Integration?
