Resolve EPA-regulated facilities, inspect transparent compliance evidence, and retain change history without opaque scores.
Resolve EPA-regulated facilities, inspect transparent compliance evidence, and retain change history without creating opaque risk scores.
Quick Start
# Resolve a name to source-preserving FRS matches.
epa-echo-pp-cli resolve facility --name 'Exxon' --state TX --agent
# Create or compare a detailed facility snapshot.
epa-echo-pp-cli dossier diff 110009441979 --agent
Unique Features
These capabilities aren't available in any other tool for this API.
resolve facility — Rank bounded facility matches while preserving FRS identifiers, addresses, program status fields, and query provenance.dossier diff — Compare a live detailed facility report with the prior local snapshot and list changed ECHO sections without assigning a score.watch — Fetch a bounded CSV portfolio of facility IDs and atomically report changed detailed-report sections since the prior run.nearby explain — List facilities within an EPA-supported radius and expose the compliance, inspection, action, and penalty fields behind each concern.effluent trend — Return ECHO's reported Clean Water Act effluent compliance and exceedance records for one stable facility identifier.enforcement timeline — Collect dated inspection, violation, formal-action, and enforcement sections from a detailed facility report without causal inference.
Recipes
Explain nearby facilities
epa-echo-pp-cli nearby explain --latitude 41.83 --longitude -71.42 --radius 5 --agent
Return bounded nearby facilities with the ECHO fields driving each concern flag.
Order enforcement evidence
epa-echo-pp-cli enforcement timeline 110009441979 --agent

Usage
Run epa-echo-pp-cli --help for the full command reference and flag list.
Paths & environment variables
This CLI separates local files into four path kinds:
| Kind | Contents |
|---|
config | User-editable settings such as config.toml and saved profiles |
data | Durable local data such as data.db |
state | Runtime state such as persisted queries, jobs, and teach.log |
cache | Regenerable HTTP/cache files |
Each kind resolves independently. The ladder is:
- Per-kind env var:
EPA_ECHO_CONFIG_DIR, EPA_ECHO_DATA_DIR, EPA_ECHO_STATE_DIR, or EPA_ECHO_CACHE_DIR
--home <dir> for this invocationEPA_ECHO_HOME for a flat relocated root- XDG env vars:
XDG_CONFIG_HOME, XDG_DATA_HOME, XDG_STATE_HOME, XDG_CACHE_HOME
- Platform defaults matching existing installs
For containers and agent sandboxes, prefer a single relocated root:
export EPA_ECHO_HOME=/srv/epa-echo
epa-echo-pp-cli doctor
Under EPA_ECHO_HOME=/srv/epa-echo, the four dirs resolve to /srv/epa-echo/config, /srv/epa-echo/data, /srv/epa-echo/state, and /srv/epa-echo/cache.
MCP servers do not receive CLI flags from the host. Put relocation in the host env block:
{
"mcpServers": {
"epa-echo": {
"command": "epa-echo-pp-mcp",
"env": {
"EPA_ECHO_HOME": "/srv/epa-echo"
}
}
}
}
Precedence matters in fleets: an ambient per-kind variable such as EPA_ECHO_DATA_DIR overrides an explicit --home for that kind. Use EPA_ECHO_HOME or the per-kind variables for durable fleet relocation; treat --home as the weaker per-invocation lever.
Relocation is one-way. Unsetting EPA_ECHO_HOME does not move files back to platform defaults, and doctor cannot find files left under a former root. Move the files manually before unsetting relocation variables.
Existing installs keep working because the platform-default rung matches the legacy layout. Run epa-echo-pp-cli doctor --fail-on warn to check path warnings in automation.

Self-learning loop
This CLI caches per-question discovery so repeat queries skip the walk and structurally similar queries get answered via entity substitution. The loop also self-captures: every invocation is journaled locally, and failed-flag corrections plus fresh teaches surface as candidates on the next recall for confirm/reject judgment. Agents call recall before discovery and fire teach & after answering. See the ## Automatic learning section in SKILL.md for the full protocol.
epa-echo-pp-cli recall <query> - Look up cached resources for a query before running discoveryepa-echo-pp-cli teach - Record a query -> resource mapping (silent on success, safe to background with &)epa-echo-pp-cli learnings list - Inspect taught rowsepa-echo-pp-cli learnings forget <query> - Undo a teachepa-echo-pp-cli learnings candidates - List auto-captured candidates awaiting confirm/rejectepa-echo-pp-cli learnings stats - Local loop metrics: recall hit rate, teach-to-reuse, playbook resolution, candidate countsepa-echo-pp-cli teach-pattern - Install a query/resource template up frontepa-echo-pp-cli teach-lookup - Add an entity mapping (e.g. country code, team alias) for pattern substitution
Pass --no-learn or set EPA_ECHO_NO_LEARN=true to disable the loop for deterministic flows.
The local store's schema version stamp is one-way: once this version of epa-echo-pp-cli opens the database, older binaries refuse it with a version error — upgrade the binary rather than downgrading.
Output Formats
# Human-readable table (default in terminal, JSON when piped)
epa-echo-pp-cli dfr-rest-services-get-dfr --p-id 110009441979
# JSON for scripting and agents
epa-echo-pp-cli dfr-rest-services-get-dfr --p-id 110009441979 --json
# Filter to specific fields
epa-echo-pp-cli dfr-rest-services-get-dfr --p-id 110009441979 --json --select FacilitySummary
# Dry run — show the request without sending
epa-echo-pp-cli dfr-rest-services-get-dfr --p-id 110009441979 --dry-run
# Agent mode — JSON + compact + no prompts in one flag
epa-echo-pp-cli dfr-rest-services-get-dfr --p-id 110009441979 --agent
Agent Usage
This CLI is designed for AI agent consumption:
- Non-interactive - never prompts, every input is a flag
- Pipeable -
--json output to stdout, errors to stderr
- Filterable -
--select id,name returns only fields you need
- Previewable -
--dry-run shows the request without sending
- Read-only by default - this CLI does not create, update, delete, publish, send, or mutate remote resources
- Offline-friendly - sync/search commands can use the local SQLite store when available
- Agent-safe by default - no colors or formatting unless
--human-friendly is set
Exit codes: 0 success, 2 usage error, 3 not found, 5 API error, 7 rate limited, 10 config error.
Health Check
epa-echo-pp-cli doctor
Verifies configuration and connectivity to the API.
Configuration
Run epa-echo-pp-cli doctor to see the resolved config, data, state, and cache directories. The platform-default config path is ~/.config/epa-echo-pp-cli/config.toml; --home, EPA_ECHO_HOME, and per-kind env vars can relocate it.
Static request headers can be configured under headers; per-command header overrides take precedence.
Troubleshooting
Not found errors (exit code 3)
- Check the resource ID is correct
- Run the
list command to see available items
