Hermes Agent is a self-improving autonomous agent with over 64K GitHub stars. Its core innovation is skills: reusable task modules that the agent creates, tests, and refines over time. But skills created from training data alone produce stale outputs. A competitor analysis skill recommends a tool that doubled its pricing three months ago. A market research skill misses a major acquisition.
The staleness problem in self-improving agents
Self-improving agents are only as good as their information sources. When Hermes creates a skill from a research task, the skill's quality depends on whether the underlying data is current. Training data has a cutoff. Web search does not. The fix is grounding: give the agent access to live search data so skills are built on current facts.
Connecting Hermes to live search via MCP
Hermes Agent supports MCP servers natively through its profile system. Add Scavio's MCP server to a research profile and Hermes discovers 11 search tools automatically. No custom tool code, no wrapper functions. Just a URL and API key in the config.
{
"profiles": {
"research": {
"mcp_servers": [{
"name": "scavio-search",
"url": "https://mcp.scavio.dev/mcp",
"auth": {
"type": "header",
"key": "x-api-key",
"value": "$SCAVIO_API_KEY"
}
}]
}
}
}Profile segmentation is critical
One of the most underrated Hermes Agent tips: do not load everything into the default profile. Create separate profiles for research, coding, writing, and analysis. The research profile gets the search MCP server. The coding profile gets your code tools. This prevents the agent from using search tools when it should be writing code, and vice versa. Context separation improves output quality across all profiles.
The self-improvement loop with grounding
When a grounded research skill runs, it pulls live data before generating output. When Hermes evaluates the skill's quality and decides to improve it, the improvement is also grounded in current data. The self-improvement loop produces progressively better skills because each iteration is verified against reality, not against potentially stale training data.
Multi-platform research
Hermes with search grounding can pull Google results for facts, Reddit threads for community sentiment, and YouTube metadata for content landscape analysis. A research skill that combines all three produces richer, more nuanced outputs than one limited to a single search platform. The MCP server's 11 tools give the agent the flexibility to choose the right platform per sub-task.
