openaccountants

OpenAccountants connector for Hermes: today's tax figures for 190+ jurisdictions through the hosted OpenAccountants MCP server. The plugin ships no skills; tax skills install separately, per jurisdiction, from the OpenAccountants agent-skills tree. Disclosure — when enabled, connects to the hosted OpenAccountants MCP server at https://www.openaccountants.com/api/mcp and its tool results enter the conversation; runs no code, needs no credentials, writes nothing. The plugin ships no skills: the README's optional skills step pipes an installer script from the openaccountants/openaccountants main branch into sh, which is outside this pin and not reviewed here. The repository mirrors upstream's plugins/openaccountants-hermes bundle every 15 minutes; the SHA pin freezes the reviewed snapshot.

About

OpenAccountants for Hermes

The OpenAccountants connector as a portable Agent Plugin (agent-plugins.org v1),
which Hermes loads natively: the hosted OpenAccountants connector ships as the
package's MCP server, giving today's figures for 190+ jurisdictions.

What installs

mcp.json — the connector at https://www.openaccountants.com/api/mcp
(streamable-http). Hermes registers it as openaccountants when the plugin
is enabled.

The plugin deliberately ships no skills. Every enabled plugin skill adds a row
to the skills index on every turn, so a 2,000-skill bundle would cost tens of
thousands of tokens per request. Install only the skills you need instead:

# pick jurisdictions by code, one skill by slug, or all, into your Hermes skills
curl -fsSL https://raw.githubusercontent.com/openaccountants/openaccountants/main/agent-skills/install.sh \
  | sh -s -- MT NL DE --to ~/.hermes/skills

Browse the full library at https://www.openaccountants.com/skills or in the
repository's agent-skills/ tree. Hermes loads only each installed skill's
short description and reads the full SKILL.md when a task matches.
