What tools exist here, and when to reach for each
emem_toolsSearch the emem tool catalog by topic, shape, category, or bundle, or retrieve one tool's schema and runnable example.
Instructions
The map of emem's tools, and the one tool that finds all the others. It gives the working loop in order (name, ground, cite, resolve, verify, check for drift). Then it groups every other tool by the question it answers, each with a one-line trigger. Send name for the full schema of one tool and an example that runs. IF YOU SEE A LIST OF 18 TOOLS, IT IS A CURATED SUBSET OF 115, NOT THE FULL SURFACE. Hosts remove _meta, so this text repeats the count. You can call every catalogued tool by name through tools/call at either endpoint.
When to use: Call this FIRST when you do not know which tool answers the question. Also call it when your list does not have a capability. A tool that is not in your list can still be on the server. q searches by topic (ndvi, flood, verify). name returns one exact schema. With no arguments, you get the full map. /mcp/full registers the full catalog. emem_ask answers in one call without a choice of primitive.
Example arguments: {"q":"ndvi"}
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| q | No | Free-text filter over tool names, titles and trigger text, e.g. `ndvi`, `cloud`, `flood`, `verify`, `token`. Plain lowercased substring over name + title + description + trigger text, not fuzzy and not stemmed: `ndvi` hits, `vegetation index` only hits tools that spell that phrase. Combines with `shape`/`bundle`/`category`/`tier` as AND, so an over-narrow combination answers with an empty catalog rather than an error. | |
| name | No | Return the full descriptor for exactly this tool (input schema, runnable example, annotations), e.g. `emem_ndvi`. Use this when you already know the name and want its schema without loading the whole catalog. It SHORT-CIRCUITS: when `name` is set every other argument here is ignored, so `{name, q}` is not a search within one tool. A name this responder does not carry is not an error status, you get a body with `did_you_mean` holding up to five names that share a substring with what you asked for. | |
| tier | No | Which slice to list. Defaults to `all`, so this tool shows the whole surface even when the endpoint advertises only the core loop, and an `extended` tool you find here is callable by name through tools/call whether or not your host listed it. Pass `core` to see only what a default connection advertises. | |
| shape | No | Filter by what the answer looks like, which is usually the real question. `scalar` is one number at one address; `raster` is a gridded field over an area; `timeseries` is a value per timestep; `vector` is a learned embedding; `identity` is a canonical name for a thing; `token` is a citation handle; `proof` checks one. | |
| bundle | No | Filter by the job you are doing. Call with no arguments first to see each bundle and its size. | |
| category | No | Filter to one category. This is about the shape of the job, NOT about safety: 43 tools outside `write` declare `readOnlyHint: false` because reading a cold address can materialise or mint as a side effect, so `category: "read"` is not a safe-tools filter. Read each result's `annotations.readOnlyHint` for that. |
