Hashgrid DNA MCP server

• create_edgewrite actionFree

  POST /nodes/{nid}/edges, the search: from query node `nid`, the best node it has not been shown yet, among those whose key starts with `prefix` ("" for any), stored as a new edge: `id` is the found node's id, `score` is null until you score it (update_edge). Null when nothing is left. Call again for the next.

• create_gridwrite actionFree

  POST /: create a grid, your own space of nodes and scores; no API key needed. Returns its `api_key`, shown only now: pass it as `api_key` to every other tool, or send it as the header `Authorization: Bearer hg-…`. It holds up to `max_nodes` nodes. Each address may create only a few grids a day.

• create_nodewrite actionFree

  POST /nodes: add a node. An item gets a `key`, a path unique in the grid (e.g. "/items/42"), so searches can find it; a query gets none. `emb` is its embedding, 1 to 2048 floats from any model; use one model per grid. Returns its id and key (not its emb, to keep replies short; get_node has it).

• delete_edgewrite actionFree

  DELETE /nodes/{nid}/edges/{eid}: forget a result, so it can be suggested again; its score no longer trains.

• delete_nodewrite actionFree

  DELETE /nodes/{nid}: delete a node and every edge from or to it; its scores no longer train.

• get_edgeFree

  GET /nodes/{nid}/edges/{eid}: one result of query `nid`, and its score (null if not scored).

• get_gridFree

  GET /: the grid the API key opens: its name, and the most nodes it holds, `max_nodes` (null: no limit).

• get_nodeFree

  GET /nodes/{nid}: a node, with its key (null if it has none) and its embedding `emb`.

• list_edgesFree

  GET /nodes/{nid}/edges: a query's results so far, each an edge with the found node's `id` and its `score` (null if not scored), in id order. `limit` is 1 to 1024; for the next page, pass the last id as `cursor`.

• list_nodesFree

  GET /nodes: the grid's nodes, each with its id, key and emb, in id order. `limit` is 1 to 1024; for the next page, pass the last id as `cursor`.

• put_edgewrite actionFree

  PUT /nodes/{nid}/edges/{eid}: score how well node `eid` fits query `nid`, from -1 (wrong) to 1 (perfect), creating the edge if DNA never suggested it, e.g. scores you already have. Only scores train DNA; a new score replaces the last.

• update_edgewrite actionFree

  PATCH /nodes/{nid}/edges/{eid}: score a result of query `nid` that create_edge returned, from -1 (wrong) to 1 (perfect). Only scores train DNA; a new score replaces the last.

• update_nodewrite actionFree

  PATCH /nodes/{nid}: change a node. `key`: a new path, or null to remove it, so the node can no longer be found; leave it out to keep it. `emb`: a new embedding; leave it out to keep it. Its scores keep training, on the new embedding. Returns its id and key.
