## Introduction

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 Vaquill 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.

## TL;DR

### What is Composio Connect?
Composio Connect is a consumer offering that lets anyone plug 1,500+ 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.

## Connect Vaquill to Hermes

### Integrating Vaquill 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
```

## What is the Vaquill MCP server, and what's possible with it?

The Vaquill MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Vaquill account. It provides structured and secure access to US statutes, legal research, citation resolution, session laws, and board-change watches, so your agent can search legal sources, resolve citations, retrieve statute text, compare provisions across states, and monitor legal changes on your behalf.
- Legal research and statute search: Have your agent search statutes, regulations, constitutions, court rules, executive actions, Federal Register materials, agency guidance, adjudications, sentencing guidelines, tax treaties, and session laws.
- Citation resolution and statute details: Direct your agent to resolve Bluebook citations, retrieve statute sections and full text, find definitions and cited-by references, and identify related enactments.
- Cross-state legal comparisons: Let the agent compare a statute section with analogous provisions in other states and retrieve adjacent sections for additional context.
- Session law research: Instruct your agent to list and inspect state session laws, retrieve their text, review metadata, and track changes to the session-law registry.
- Legal change monitoring: Have your agent discover watchable legal sources, create and manage board watches, list observed changes and delivery attempts, inspect change diffs, and send test notifications.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `VAQUILL_BROWSE_STATUTE_DIVISIONS` | Browse Statute Divisions | Browse one level of a statutory hierarchy at a time. Costs 1 credit per page. |
| `VAQUILL_COMPARE_STATUTE_CROSS_STATE` | Compare Statute Cross State | Find the top analogous statutory provisions in other states for one state statute section. Costs 6 credits and supports state-statute sections only. |

| `VAQUILL_CREATE_BOARD_WATCH` | Create Board Watch | Create an active email, webhook, or dual-channel watch that immediately begins monitoring a legal corpus source and may send future external email or webhook notifications until paused or deleted. Email works on every documented plan; webhook and both require Business. The watch cap is 3 outside Business and 100 on Business, and duplicate board/channel/scope combinations return a conflict. |
| `VAQUILL_DELETE_BOARD_WATCH` | Delete Board Watch | Permanently delete a board watch and all of its delivery history. This cannot be undone. Pause the watch instead when its configuration or history must be retained. This endpoint is free. |
| `VAQUILL_GET_ADJACENT_STATUTE_SECTIONS` | Get Adjacent Statute Sections | Get the immediately adjacent sections before and after a statute section in statutory order. Costs 2 credits. |
| `VAQUILL_GET_API_CREDIT_PRICING` | Get API Credit Pricing | Get Vaquill's live credit conversion, purchase bounds, and per-operation prices without authentication or credit consumption. |
| `VAQUILL_GET_BOARD_WATCH_CHANGE_DIFF` | Get Board Watch Change Diff | Get complete old and new section text for one exact observed watch change. Call only for a change returned with has_diff=true. This is the alerts family's only metered route and normally costs 4 credits. Vaquill refunds the call when an amended change is missing either side, its resolved sides are identical, or no text resolves. |
| `VAQUILL_GET_CREDIT_BALANCE` | Get Credit Balance | Get the connected Vaquill account's spendable credits, USD balance, expiries, plan, lifetime usage, and applied request limits. This read is free and does not consume credits. |
| `VAQUILL_GET_SESSION_LAW` | Get Session Law | Get complete metadata for one US state session law by provider ID or citation. An exact provider ID costs 2 credits; citation input may also incur Vaquill's separate citation-resolution surcharge. |
| `VAQUILL_GET_SESSION_LAW_BODY` | Get Session Law Body | Get one page of a US state session law's text, with character offsets, text hash, and amendatory-markup metadata. Vaquill charges 6 credits per served page. Unavailable text is not charged; not-found, stale-cursor, and server failures are not charged or are refunded. |
| `VAQUILL_GET_SESSION_LAWS_BATCH` | Get Session Laws Batch | Get up to 50 distinct US state session laws by provider ID or citation. Vaquill charges 2 credits per law served; each citation also costs 2 resolution credits when a verdict is produced. include_body adds 6 credits per first body page served. Misses incur no batch-route charge. Validation errors are uncharged; provider 500/503 failures and resolution charges for session_not_fully_collected or lookup errors are refunded. |
| `VAQUILL_GET_STATUTE_BODY` | Get Statute Body | Get full statute text in a selected format, optionally with a subsection tree or point-in-time reconstruction. Costs 6 credits when text is returned. Ordinary unavailable text and fetch failures are refunded. Historical available:false answers are charged when the section did not yet exist or a stored-edition date is outside held coverage; unavailable observed-change reconstructions are refunded. |
| `VAQUILL_GET_STATUTE_CITED_BY` | Get Statute Cited By | Find the top USC and CFR sections that cite a statute section. Costs 2 credits; results are bounded by limit and are not pageable. |
| `VAQUILL_GET_STATUTE_DEFINITIONS` | Get Statute Definitions | Get chapter definitions governing a statute section. Costs 4 credits; no-definition and failed lookups are refunded. |
| `VAQUILL_GET_STATUTE_ENACTMENTS` | Get Statute Enactments | Get state session laws whose publisher affected-sections tables print this exact code section. This is not complete amendment history. Supported existing sections cost 1 credit, including empty answers; unsupported or missing sections and provider 500/503 failures are uncharged or refunded. Citation input adds the 2-credit resolution charge. Results are capped at the newest 200 with no continuation; inspect truncated and coverage. |
| `VAQUILL_GET_STATUTES_COVERAGE` | Get Statutes Coverage | Return Vaquill's authoritative live jurisdiction and corpus coverage matrix before choosing statute search filters. This discovery call costs no credits. |
| `VAQUILL_GET_STATUTE_SECTION` | Get Statute Section | Get metadata and source links for one US statute section by canonical section ID or resolvable citation. Costs 2 credits for an exact ID; citation input also incurs Vaquill's citation-resolution charge. |
| `VAQUILL_GET_STATUTE_SECTIONS_BATCH` | Get Statute Sections Batch | Get metadata for up to 50 statute sections in input order, with optional full text. Costs 2 credits per section returned, plus the ordinary body charge for each included body; unresolved identifiers are refunded. |
| `VAQUILL_LIST_BOARD_WATCH_CHANGES` | List Board Watch Changes | List sections observed as added, amended, or removed on a watched source. History is capture-bounded, retained for five years, and this call is free. |
| `VAQUILL_LIST_BOARD_WATCH_DELIVERIES` | List Board Watch Deliveries | List the newest persisted webhook delivery attempts and current delivery health for a board watch. History is retained for 90 days and this bounded limit-only endpoint has no second page. Email-only watches return no attempts, and synthetic test deliveries are excluded. The read is free, but meaningful history requires a webhook or both-channel watch, which requires Vaquill Business. |
| `VAQUILL_LIST_BOARD_WATCHES` | List Board Watches | List board watches owned by the connected Vaquill API-key account, including delivery destination, active state, and latest health metadata. Costs no credits. |
| `VAQUILL_LIST_SESSION_LAW_CHANGES` | List Session Law Changes | List one oldest-first page of changes to Vaquill's state session-law registry for incremental synchronization. Costs 1 credit per page, including an empty page; validation failures are not charged and provider failures are refunded. |
| `VAQUILL_LIST_SESSION_LAWS` | List Session Laws | List one page of a state's session laws with session, date, text-availability, and instrument filters. Costs 1 credit per page. Empty pages are refunded when coverage reports a wholly partial or not-held collection; complete and partly complete jurisdiction pages are charged. |
| `VAQUILL_LIST_STATUTE_CHANGES` | List Statute Changes | List capture-bounded observed change history for a statute section. This is not complete legislative history. Costs 1 credit per page. |
| `VAQUILL_LIST_WATCHABLE_BOARDS` | List Watchable Boards | List corpus sources that can be watched, including freshness, polling cadence, retrieval health, and supported scope filters. Costs no credits. |

| `VAQUILL_RESOLVE_STATUTE_CITATIONS_BATCH` | Resolve Statute Citations Batch | Resolve up to 50 unique Bluebook citations in one call from a raw list of up to 500 entries. Duplicates are collapsed, and each unique citation costs 2 credits. |
| `VAQUILL_SEARCH_US_STATUTES` | Search US Statutes | Search US statutes and regulations, constitutions and court rules, executive actions and Federal Register materials, agency guidance and adjudications, sentencing guidelines, tax treaties, and session laws with semantic and keyword matching. Costs 4 credits, plus 6 credits for each full body returned. |
| `VAQUILL_TEST_BOARD_WATCH` | Test Board Watch | Send one synthetic delivery through a board watch's configured channel immediately. This external side effect is limited to one test per watch every 30 seconds, is not saved in delivery history, and does not change the watch's real last-notified state. |
| `VAQUILL_UPDATE_BOARD_WATCH` | Update Board Watch | Partially update a Vaquill board watch without changing its delivery channel. Omitted fields remain unchanged.

## Conclusion

### Way Forward
With Vaquill 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.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Vaquill MCP?

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

### Can I use Tool Router MCP with Hermes?

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 Vaquill tools.

### Can I manage the permissions and scopes for Vaquill while using Tool Router?

Yes, absolutely. You can configure which Vaquill 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.

### How safe is my data with Composio Tool Router?

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 Vaquill data and credentials are handled as safely as possible.
