The CRM for Hermes. Run it from your own GPU.

Hermes is the open source LLM family and agent runtime from Nous Research. Hermes 4 ships under MIT and is one of the very few open weights families specifically trained for production grade function calling, structured output and multi turn tool use. Hermes Agent, released in early 2026, wraps the model with persistent memory, autonomous skill creation and local inference through Ollama, vLLM or llama.cpp. The whole stack runs on your own hardware, with full data sovereignty.

For a small but loud crowd of developers, founders and indie builders, that combination is the entire bet. Closed model APIs are convenient but they leak context, charge per token and gate the agent loop behind their own roadmap. Hermes flips the model: your weights, your GPU, your skill library. The only piece that becomes a bottleneck is the CRM that the agent is meant to operate on top of.

Breakcold is built for that bottleneck. The first reason Hermes builders pick it is the **first party **MCP server. 50 plus tools across 17 AI clients including Hermes, Claude Code, Cursor, Cowork and OpenClaw. The tool surface is shaped for production grade function calling, which is exactly the shape Hermes was trained on. Fewer retries, cleaner tool calls, more shipped automations.

The second reason is the data the MCP actually exposes. Most CRM MCPs stop at records, deals and tasks. Ours covers the full multichannel inbox: email, calls, meetings, LinkedIn, Telegram and WhatsApp. Hermes reasons over what was actually said in the thread when it builds a recap or scores a deal, not just a basic Contact and Deal record. That difference compounds when the agent has persistent memory.

The third reason is the data model. Custom objects, custom fields and custom relations are first class on the base plan. The data model is solidly number 2 after Attio in depth and architecturally comparable. Hermes can model an actual sales motion (deals, partners, renewals, accounts of accounts) instead of a flattened Contact and Company spreadsheet. The difference with Attio is audience: Attio targets 50 plus person companies with a dedicated GTM engineer, Breakcold gives the same depth without that requirement.

The fourth reason is the admin angle. Most teams put their AI agent on outreach and watch it write bad emails. Hermes builders tend to be different. They want the agent to run the boring half of the CRM: pipeline reports, record updates, auto tasks from a conversation, weekly recaps. Persistent memory plus the autonomous skill loop means the team builds up a library of reusable CRM recipes that get sharper every week.

Pricing is the last gap. Hermes is MIT and runs on your own hardware, so the variable cost is GPU time. Breakcold is $59 per month for the base plan, one seat and one channel account included, with full MCP, full API and unlimited enrichment. Extra seats are $10 per month, extra accounts are $10 per month. A 5 person team is $99 per month flat. Compare that to Salesforce Einstein at $50 per seat on top of $165 base, or HubSpot Breeze gated to the top tier, both with their own closed agent loop you do not control.
