A search engine that learns from your grades. Store text, records, images or embeddings.
A remote store of text, records, images and embeddings whose search results improve as you grade them, exposed to assistants as grid, item, query and grade…
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/ai.hashgrid%2Fdna/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}POST /: create a grid, your own store of items; 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_items` items, queries included. Each address may create only a few grids a day.
nameGET /: the grid the API key opens: its name and its limit on items, `max_items` (queries included; null: no limit).
api_keyDELETE /: delete the grid and everything in it, items, queries and grades; its key stops working.
api_keyPUT /items/key: write the item at `key` (e.g. "42", no leading /), creating it or replacing its content. Text is a string and a record a JSON object, each up to 8 KB; an image its bytes as base64, kept as a WebP of at most 512 px (its width and height come back); an emb a list of floats from the grid's model. DNA embeds the rest itself and keeps it only to embed it again; results and listings never return it. `type` is one of text/plain, application/json, image/png, image/jpeg, image/webp, image/gif, application/vnd.hashgrid.emb+json; leave it out for text, a record or an emb, which DNA tells apart, not for an image. Group items under a prefix (e.g. "tools/42") to search groups apart. Returns the item: its key, type, size, etag, ctime and mtime.
keyrequiredtypeapi_keycontentrequiredGET /items/key: the item at `key`, with its `content` as put_item takes it.
keyrequiredapi_keyDELETE /items/key: delete the item at `key`, and every grade of it.
keyrequiredapi_keyGET /items?prefix=: `items`, those whose keys start with `prefix` (e.g. "tools/"; all by default), in key order, without their content (get_item reads one), at most `limit` (1 to 100, 32 by default). `next`: for the next page, pass it as `after` (null: this was the last).
afterlimitprefixapi_keyPOST /queries: store a question to ask of the items, its content as put_item takes it. Returns its `id`, which the other query tools take. Its results are ready at once; ask again with the same `id` rather than creating the same query twice, so its grades add up.
typeapi_keycontentrequiredGET /queries/id: the query `id`, with its `content` as create_query takes it.
idrequiredapi_keyDELETE /queries/id: delete the query `id` and its grades.
idrequiredapi_keyGET /queries/id/results: `results`, the query's best items under any of `prefixes` (e.g. ["tools/"]; all items by default), best first, each with its `score`, DNA's estimate of the grade you would give it (on the grades' scale once the grid has some; before, only the order means anything), as list_items shows it, without content. `ungraded`: leave out the items you already graded for this query. Grade what you judged with put_grade: the results learn from it within a few seconds.
idrequiredlimitapi_keyprefixesungradedPUT /queries/id/grades/key: grade the item at `key` (as get_results returns it, e.g. "42") for the query `id`. `score` is from -1 (wrong) to 1 (right), anything between for partly right; it trains DNA and replaces the grade before. Grade the results you judged, typically the first few.
idrequiredkeyrequiredscorerequiredapi_keyGET /queries/id/grades/key: the query's grade of the item at `key`.
idrequiredkeyrequiredapi_keyDELETE /queries/id/grades/key: forget the query's grade of the item at `key`.
idrequiredkeyrequiredapi_keyGET /queries/id/grades: `grades`, the query's grades, {"key", "score"}, in path order.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
Declare a GitHub repository with a README, or serve resource_documentation in the OAuth protected-resource metadata.
A hosted service is used under its provider's terms, so no license is expected here. This check is left out of the percentage.
