Esheria Regulatory Intelligence

Esheria CLI And MCP

Installable command-line and MCP tools for the Esheria Regulatory Pack API.

Global, citation-backed regulatory intelligence for explicit published packs. Discover current readiness, select the intended jurisdiction and pack, and preserve citations, versions, limitations, and trace IDs across CLI, Python, and MCP workflows. Esheria provides regulatory intelligence, not legal advice.

The package exposes two commands:

esheria --helpesheria-mcp --helpesheria mcp serve --help

CLI Quickstart

1. Create a data API token in the Esheria dashboard.
2. Install the command. pipx is recommended because it keeps command-line tools isolated from project dependencies:

pipx install esheria

If you do not use pipx, use normal pip:

python3 -m pip install esheria

3. Configure your shell. Put these in your terminal for a one-off test, or in ~/.zshrc, ~/.bashrc, or your shell profile to keep them:

export ESHERIA_API_BASE_URL="https://api.esheria.ai"export ESHERIA_API_KEY="<client-api-key>"

PowerShell:

$env:ESHERIA_API_BASE_URL = "https://api.esheria.ai"$env:ESHERIA_API_KEY = "<client-api-key>"

ESHERIA_API_TOKEN is also accepted as an alias when ESHERIA_API_KEY is unset.

Do not commit API keys. The CLI and MCP server read credentials from environment variables or command-line flags and redact API key values from diagnostic output. Prefer the environment variable: --api-key can be exposed through shell history or the operating-system process list.

4. Confirm the API is reachable:

esheria --versionesheria health --format jsonesheria ready --format json

5. Discover packs, choose a domain_pack_id, then pass that pack ID to pack-specific commands:

esheria packs list --format jsonexport ESHERIA_PACK_ID="UK-DATA-PROTECTION-PRIVACY"esheria packs inspect "$ESHERIA_PACK_ID" --format jsonesheria packs versions "$ESHERIA_PACK_ID" --format jsonesheria packs diff "$ESHERIA_PACK_ID" --format jsonesheria packs change-events "$ESHERIA_PACK_ID" --format jsonesheria obligations list "$ESHERIA_PACK_ID" --limit 3 --format jsonesheria penalties list "$ESHERIA_PACK_ID" --limit 5 --format jsonesheria legal-review audit "$ESHERIA_PACK_ID" --limit 5 --format json

Output flags can be placed globally or on a leaf command:

esheria --format json packs listesheria packs list --format json

Use esheria --help and <group> --help to discover the full command tree. The CLI includes source-watch operations, graph coverage/rebuild operations, workspace-scoped customer lifecycle commands, and workspace/token/billing management commands in addition to the read workflows above.

Workspace, token, and billing commands require a management token. Normal dashboard-created and OAuth connector tokens carry only regulatory:read. State-changing regulatory workflows require an explicitly created operator data token with one or more of monitoring:write, graph:write, or customer:write; regulatory:read alone is rejected. For example:

esheria tokens create \  --name "Monitoring operator" \  --scope regulatory:read \  --scope monitoring:write \  --pack UK-DATA-USE-AND-ACCESS

The dashboard remains the recommended place for self-serve workspace, token, billing, and subscription administration. Keep operator tokens short-lived and grant only the scopes and pack entitlements they require.

The CLI and MCP server are catalog-first: users list packs and then call tools with the explicit pack ID they want. ESHERIA_DEFAULT_PACK_ID is an optional client preference, not a server-side jurisdiction default.

The CLI reports the API's readiness labels, limitations, citations, and trace IDs; preserve them in downstream workflows. Published packs may represent a reviewed subset of the full legal corpus, and evaluator-gated claim verification is not available for every pack. Esheria output is regulatory intelligence, not legal advice or a substitute for qualified counsel.

Hosted MCP

Production MCP uses the hosted Esheria endpoint:

https://mcp.esheria.ai/mcp

Use this endpoint for normal customer onboarding. It avoids local Python, uvx, virtual environments, and package discovery on the user's machine.

Claude Directory hosts use OAuth. Other agent hosts send a dashboard-created Esheria data token as a bearer token or X-API-Key. The hosted MCP server introspects the credential before initialization and calls the Regulatory Pack API with it, so billing, pack entitlements, trace IDs, and published-only behavior remain centralized. Invalid and management-only credentials cannot enumerate tools.

Codex MCP

Set the token where Codex can read it:

export ESHERIA_API_KEY="<client-api-key>"

Edit ~/.codex/config.toml and add:

[mcp_servers.esheria]url = "https://mcp.esheria.ai/mcp"bearer_token_env_var = "ESHERIA_API_KEY"

Restart Codex, then call esheria_health, esheria_ready, and esheria_list_packs.

Local MCP Fallback

For local development, or for agent hosts that do not support remote MCP URLs, you can run the stdio server yourself:

esheria-mcp serve --stdio

Operator-only HTTP transport command:

ESHERIA_API_BASE_URL="https://api.esheria.ai" \  esheria-mcp serve --http --host 127.0.0.1 --port 8081 --path /mcp

Production is already deployed at https://mcp.esheria.ai/mcp; end users should not run this command.

The hosted OAuth profile exposes a read-only 20-tool catalog for health, readiness, pack discovery, obligations, applicability, claim verification, versions, diffs, change events, filing calendars, evidence, penalties, audit metadata, relationship queries, exports, and citation context. Normal API data tokens expose 29 safe read/read-like tools. Operator data tokens add only mutations authorized by monitoring:write, graph:write, and/or customer:write, up to the complete 37-tool catalog. Every mutation also requires confirm=true; OAuth Directory sessions remain read-only.

The hosted service uses the official MCP SDK and current Streamable HTTP. Successful tools mirror bounded JSON in text content and structuredContent, with trace_id and mcp truncation metadata. Use the API or CLI when a complete large export is needed.

Use stdio only for hosts that do not support remote MCP URLs:

[mcp_servers.esheria]command = "uvx"args = ["--from", "esheria", "esheria-mcp", "serve", "--stdio"]env = { ESHERIA_API_BASE_URL = "https://api.esheria.ai", ESHERIA_API_KEY = "<client-api-key>" }

Claude Code

Use Claude Code's remote MCP setup when your installed version exposes it:

• URL: https://mcp.esheria.ai/mcp
• Authorization: Bearer <client-api-key>

If your Claude Code version only supports local stdio MCP servers, run this fallback once from a terminal:

claude mcp add --scope user --transport stdio \  --env ESHERIA_API_BASE_URL=https://api.esheria.ai \  --env ESHERIA_API_KEY=<client-api-key> \  esheria -- uvx --from esheria esheria-mcp serve --stdio

Then run:

claude mcp list

Start or restart Claude Code and ask it to use the Esheria MCP tools.

Claude Desktop

Use Claude Desktop's remote MCP setup when your installed version exposes it:

• URL: https://mcp.esheria.ai/mcp
• Authorization: Bearer <client-api-key>

If your Claude Desktop version only supports local stdio MCP servers, use the fallback below.

Open the Claude Desktop MCP config file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

Add or merge this object:

{  "mcpServers": {    "esheria": {      "command": "uvx",      "args": ["--from", "esheria", "esheria-mcp", "serve", "--stdio"],      "env": {        "ESHERIA_API_BASE_URL": "https://api.esheria.ai",        "ESHERIA_API_KEY": "<client-api-key>"      }    }  }}

Restart Claude Desktop after saving the file.
