How to integrate Fireworks AI MCP with Hermes

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 Fireworks AI 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 Composio Connect?

Composio Connect is a consumer offering that lets anyone plug 1,000+ applications directly into their agent harness — including Hermes. It can:

  • Search and load tools from relevant toolkits on-demand, reducing context usage.
  • Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM.
  • Manage app authentication end-to-end with zero manual overhead.

Integrating Fireworks AI with Hermes

Using Composio Connect CLI

1. Install the Composio CLI

Run the install script directly, or paste https://composio.dev/hermes into your Hermes chat box to have it installed for you.

bash
curl -fsSL https://composio.dev/install | bash
Hermes authenticating with Composio

2. Authenticate

Once the CLI is installed, ask Hermes to authenticate with Composio.

3. Connect to Fireworks AI

Ask your agent to connect to Fireworks AI, or simply request any Fireworks AI-related task. Hermes will prompt you to authenticate and authorize access.

4. Done. You're all set with a new Fireworks AI connection.


Using Composio Connect MCP

1. Get your MCP URL and API Key

Go to dashboard.composio.dev and copy your Connect MCP URL and API key.

Copy MCP URL and API key from Composio dashboard

2. Open the Hermes config file

bash
nano ~/.hermes/config.yaml

3. Add the Composio Connect MCP server

bash
mcp_servers:
  composio:
    url: "https://connect.composio.dev/mcp"
    headers:
      x-consumer-api-key: "YOUR_COMPOSIO_API_KEY"
    connect_timeout: 60
    timeout: 180

Save with Ctrl + O, Enter, then exit with Ctrl + X.

4. Restart your Hermes agent

Once restarted, ask your agent to connect to Fireworks AI or request any Fireworks AI-related task. It will prompt you to authenticate and authorize access.

5. Done!

What is the Fireworks AI MCP server, and what's possible with it?

The Fireworks AI MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Fireworks AI account. It provides structured and secure access to model inference, embeddings, reranking, models, deployments, and account information, so your agent can generate responses, create embeddings, rank documents, inspect models, and monitor deployments on your behalf.

  • Conversational model responses: Have your agent generate chat completions or other model responses from your prompts and role-based conversations.
  • Semantic embeddings: Instruct your agent to turn text into embedding vectors for search, clustering, recommendations, or similarity analysis.
  • Relevant document ranking: Let the agent rank a collection of documents against a query so the most useful results appear first.
  • Model discovery and inspection: Direct your agent to list available models and review the metadata and status of a specific model.
  • Account and deployment visibility: Have your agent find accessible accounts, list deployments, and inspect deployment configuration, serving capacity, and status.

Way Forward

With Fireworks AI 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.

TOOLS

Supported Tools

Every Fireworks AI action and event your agent gets out of the box.

Create Chat Completion

Generate one non-streaming OpenAI-compatible chat completion from role-based messages using a caller-supplied Fireworks model or deployment ID.

Create Embeddings

Create embedding vectors for one or more caller-provided inputs using a caller-supplied Fireworks embedding model.

Generate Model Response

Generate one non-streaming Responses API result, optionally continuing a stored response or using function, MCP, or SSE tools; storage is off by default.

Get Deployment

Return configuration and serving status for one Fireworks deployment without scaling or modifying it.

Get Model

Return metadata and status for one model resource in a Fireworks account; this does not test whether the model can serve inference.

List Accounts

Return one page of Fireworks accounts accessible to the API key so an agent can obtain account IDs for model and deployment discovery.

List Deployments

Return one page of deployment resources in a Fireworks account for deployment ID discovery and serving-capacity and status inspection.

List Models

Return one page of model resources in a Fireworks account for model-ID discovery and status inspection; availability for inference is not guaranteed.

Rerank Documents

Rank a provided document list by relevance to a query using an optional caller-supplied Fireworks reranker model.

FAQ

Frequently asked questions

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

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 Fireworks AI tools.

Yes, absolutely. You can configure which Fireworks AI 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.

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 Fireworks AI data and credentials are handled as safely as possible.
