Best tools to install on a Hermes agent

The short list

1. 1

   Locus Pro

   One connection for thousands of paid APIs — search, enrichment, finance, voice, verification — billed per call from one balance.

   hermes mcp add --url https://api.paywithlocus.com/api/credits/mcp --auth oauth locus

2. 2

   Brave Search

   General web search with grounding-grade results for research tasks.

   hermes mcp install brave-search

3. 3

   Playwright

   Real browser automation: open pages, click, screenshot, and scrape JavaScript-heavy sites.

   hermes mcp add playwright --command npx --args -y @playwright/mcp@latest

4. 4

   GitHub

   Read and manage repos, issues, and pull requests without leaving the agent.

   hermes mcp install github

5. 5

   Filesystem

   Scoped read and write access to project directories on the host machine.

   hermes mcp add filesystem --command npx --args -y @modelcontextprotocol/server-filesystem /path/to/project

6. 6

   Fetch

   Pull a URL into context as markdown for quick reads without a full browser.

   hermes mcp install fetch

After adding a server that needs approval, run hermes mcp login locus (replace locus with the server name) to complete OAuth, then reload tools inside chat. For the full walkthrough, see how to set up Hermes.

Why Locus Pro belongs on the list

Free servers cover search, browsing, and files. The moment the agent needs specialist data — company enrichment, verified contacts, market filings, transcripts, threat lookups — each provider normally means another account, another key, another subscription. Locus Pro replaces all of that with one MCP connection and one prepaid balance: the agent searches the agent tool catalog, sees the price before each call, and spends only what permitted calls cost.
