## Introduction

Hermes is a 24/7 autonomous agent that lives on your computer or server — it remembers what it learns and evolves as your usage grows.
This guide explains the easiest and most robust way to connect your Vercel AI Gateway account to Hermes. You can do this through either Composio Connect CLI or Composio Connect MCP. For personal use we recommend the CLI, but you won't go wrong with MCP either.

## What is the Vercel AI Gateway MCP server, and what's possible with it?

The Vercel AI Gateway MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Vercel AI Gateway account. It provides structured and secure access so your agent can perform Vercel AI Gateway operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `VERCEL_AI_GATEWAY_COMPACT_RESPONSE` | Compact Response | Compact a long OpenAI Responses conversation into replayable context through Vercel AI Gateway. This endpoint only supports models routed to OpenAI and does not fail over to other providers; model compatibility is checked by the provider rather than by this action. |
| `VERCEL_AI_GATEWAY_COUNT_MESSAGE_TOKENS` | Count Message Tokens | Estimate input tokens for Anthropic-format messages, system content, and tools before sending a model request through Vercel AI Gateway. |
| `VERCEL_AI_GATEWAY_CREATE_ANTHROPIC_MESSAGE` | Create Anthropic Message | Create one non-streaming Anthropic Messages-compatible result through Vercel AI Gateway, with multimodal content, tools, extended thinking, and routing controls. |
| `VERCEL_AI_GATEWAY_CREATE_CHAT_COMPLETION` | Create Chat Completion | Create one non-streaming OpenAI Chat Completions-compatible result through Vercel AI Gateway, with multimodal messages, tools, structured output, fallback models, and routing controls. |
| `VERCEL_AI_GATEWAY_CREATE_EMBEDDINGS` | Create Embeddings | Generate OpenAI-compatible vector embeddings through Vercel AI Gateway for text or token inputs, with optional dimensions and routing controls. |
| `VERCEL_AI_GATEWAY_EDIT_IMAGES` | Edit Images | Create edited images from up to 16 HTTPS or base64 data-URL source images and a text instruction. Uses the non-streaming JSON image-edit route only. |
| `VERCEL_AI_GATEWAY_EVALUATE_STATE` | Evaluate State | Evaluate one shared state against one or more typed choice, score, or boolean questions using an AI Gateway evaluation model. Returns structured answers, token usage, and gateway metadata rather than generated prose. |
| `VERCEL_AI_GATEWAY_GENERATE_IMAGES` | Generate Images | Generate one or more images from a text prompt through an image-only Vercel AI Gateway model. Returns a completed non-streaming JSON response. |
| `VERCEL_AI_GATEWAY_GENERATE_RESPONSE` | Generate Response | Generate one non-streaming OpenAI Responses-compatible result through AI Gateway, with optional instructions, tools, structured output, reasoning, and routing controls. Inspect status because a successful HTTP response may still be incomplete. |
| `VERCEL_AI_GATEWAY_GENERATE_SPEECH` | Generate Speech | Generate spoken audio from text through a Vercel AI Gateway speech model. Returns completed base64 audio in JSON; streaming output is not supported. |
| `VERCEL_AI_GATEWAY_GET_CREDIT_BALANCE` | Get Credit Balance | Return the connected team's remaining AI Gateway credit balance and lifetime credit usage in USD. |
| `VERCEL_AI_GATEWAY_GET_GENERATION` | Get Generation | Look up cost, token usage, provider routing, latency, and finish details for one completed Vercel AI Gateway generation. |
| `VERCEL_AI_GATEWAY_GET_MODEL` | Get Model | Return detailed capabilities, modalities, limits, tags, and pricing for one exact Gateway model ID. |
| `VERCEL_AI_GATEWAY_GET_MODEL_ENDPOINTS` | Get Model Endpoints | Compare provider endpoints serving one Vercel AI Gateway model, including limits, pricing, caching, availability, throughput, and latency. |
| `VERCEL_AI_GATEWAY_GET_SPEND_REPORT` | Get Spend Report | Query aggregated Vercel AI Gateway spend and token usage. This endpoint requires a Pro or Enterprise plan, and each query costs $5 per 1,000 queries. |
| `VERCEL_AI_GATEWAY_LIST_MODEL_CATALOG` | List Model Catalog | List AI Gateway model-to-provider routes and capability tags, with bounded local filtering by model text, provider, or tag. |
| `VERCEL_AI_GATEWAY_LIST_TYPESAFE_MODELS` | List TypeSafe Models | List evaluation models available through AI Gateway's TypeSafe-compatible API, including each accepted model name, description, and release date. |
| `VERCEL_AI_GATEWAY_RERANK_OBJECT_DOCUMENTS` | Rerank Object Documents | Rank structured object documents by relevance through the Cohere v1 route, using selected rank fields and optionally returning each source document. |
| `VERCEL_AI_GATEWAY_RERANK_TEXT_DOCUMENTS` | Rerank Text Documents | Rerank string documents through the current Cohere v2 compatibility endpoint. Unlike the v1 action, this action accepts text strings only and does not support object documents, rank_fields, or return_documents. |

## Conclusion

### Way Forward
With Vercel AI Gateway connected, Hermes can now act on your behalf whenever it detects a relevant task or you ask it to.
From here, you can extend Hermes further:
- Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Hermes can do for you.
- Build workflows across tools: Once multiple apps are connected, Hermes can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft.
- Let it learn your patterns: The more you use Hermes, the better it gets at anticipating how you'd handle recurring tasks. Give it feedback on drafts and decisions, and it will adapt.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Vercel AI Gateway MCP?

With a standalone Vercel AI Gateway MCP server, the agents and LLMs can only access a fixed set of Vercel AI Gateway tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Vercel AI Gateway and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Hermes?

Yes, you can. Hermes fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Vercel AI Gateway tools.

### Can I manage the permissions and scopes for Vercel AI Gateway while using Tool Router?

Yes, absolutely. You can configure which Vercel AI Gateway scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Vercel AI Gateway data and credentials are handled as safely as possible.
