Real-time public hazard, water, weather and EPA data with source and licence on every reading
Aggregates public environmental data from NOAA, USGS, EPA and other sources. Muse can fetch current readings for weather, water levels, earthquakes, air quality and hazards at specific locations, with full provenance and licence information.
Try asking Muse: "Show me the current water level at the USGS gauge near my town and whether it's above normal."

Each bar is one check, every 15 minutes. Green means it answered. Last checked 2 h ago.
What Muse can see: It does not ask you to sign in, so it cannot see your accounts. It only sees what Muse sends it from your request.
Before it acts: Read what Muse plans to do before you approve it, and remove the app from Muse when you stop using it.

Not in Muse's Connectors list yet, but Muse can still use it. Copy the request below and paste it into Muse. Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Open Signals is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
In Claude, open Settings, then Connectors.
Choose Add custom connector, give it a name, and paste the link.
If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.
Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

Screened, no issues found
Screening looks for known threats and hidden instructions at the time of the check, and runs again weekly and whenever the tool list changes. It cannot see the server's code, so only connect what you need and review what Muse asks to do. How screening works.
search_sourcesSearch the catalogue of public data sources (weather, water, hazards, flights, ships, energy, filings, trade, ...). Each entry gives the API, coverage, cadence, auth needed and licence. Use it to find where a kind of data comes from before writing a fetcher.get_sourceOne catalogue entry in full.list_hubsProjects and catalogues that collect sources (God's Eye View, World Monitor, the MCP Registry, Source Cooperative, ...), with how each relates to this one.list_placesNamed places the fetchers read for, with their upstream ids (CO-OPS station, USGS gauge, eBird region) and tags.get_readingsFetch current readings from one source, each with value, unit, a one-line summary, place and provenance (source, URL, fetch time, licence). Sources this server will not republish (non-commercial, restricted or unreviewed licence) answer with an error naming the licence.list_datasetsStatic public datasets this server holds as GeoJSON (wildfire burn perimeters, public-land share by county, federal campgrounds, fire-weather stations), with source, licence, feature count and parts (one per state, or "all").get_dataset_partThe URL of one part of a dataset as GeoJSON, plus its description. Fetch the URL for the features; parts can be several megabytes.list_layersMap layers this server can draw as GeoJSON, with unit, source, licence, whether it is available here, and how to read it.get_layerOne map layer as a GeoJSON FeatureCollection: one point per place with the reading on the date (else the latest observed before it, never a guess), or one point per event for event layers.https://open-signals.civops.io/mcpNot in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Open Signals to help me. It is a free service with an MCP server at https://open-signals.civops.io/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust.

At the last check (October 29, 2026, 09:30 UTC) the endpoint was working, answering in 105ms. Over the last 7 days it answered 100% of health checks. It is checked every 15 minutes.
It was screened on October 29, 2026 with the result "screened, no issues found". Screening checks the domain against threat feeds and reads the tools for hidden instructions and requests for passwords or card numbers. It cannot see the server's code, so grant only the access you need.
It exposes 9 tools, including search_sources, get_source, list_hubs, list_places. For example, you could ask Muse: "Show me the current water level at the USGS gauge near my town and whether it's above normal."
