Create index

(re)indexes a repository for the caller's org, incrementally: files whose content hash is unchanged are skipped, so re-sending a whole tree is cheap.

Address	`https://api.hanzo.ai/v1/code/index`
Method	`POST`
Operation	`post_code_index`
Auth	`Authorization: Bearer $HANZO_API_KEY`

(re)indexes a repository for the caller's org, incrementally: files whose content hash is unchanged are skipped, so re-sending a whole tree is cheap. Each file is parsed for symbols, split at AST boundaries and — when the semantic tier is available — embedded, which is what makes it searchable across all three retrieval tiers. Pass prune to also DELETE indexed files absent from the request, which turns the call into a full sync; without it the call is an upsert. The index is written to the caller org's own physically separate database.

Request

5 fields, body application/json (required).

Field	In	Type	Required	Description
`files`	body	code.fileInput[]	—	Files is the full set of files to index.
`files[].content`	body	string	—	Content is the file's full text.
`files[].path`	body	string	—	Path is the file's repo-relative path, e.g. "internal/store/db.go".
`prune`	body	boolean	—	Prune deletes indexed files that are NOT in this request — which makes the call a full sync of the repo rather than an upsert.
`repo`	body	string	—	Repo is the repository label to index under.

Response

Status	Body	Meaning
`200`	code.indexResult	ok
`default`	problem-details	refused

200 body — 9 fields.

Field	In	Type	Always	Description
`chunks`	body	integer (int64)	—	Chunks is how many AST-boundary chunks the repo holds after this pass.
`files`	body	integer (int64)	—	Files is how many files the repo holds after this pass.
`indexed`	body	integer (int64)	—	Indexed is how many files were parsed and written on this pass.
`pruned`	body	integer (int64)	—	Pruned is how many stored files were deleted because prune was set and they were absent from the request.
`repo`	body	string	—	Repo is the repository that was indexed.
`semantic`	body	boolean	—	Semantic reports whether the semantic tier was available for this pass.
`skipped`	body	integer (int64)	—	Skipped is how many files were unchanged by content hash and left alone.
`symbols`	body	integer (int64)	—	Symbols is how many symbol definitions the repo holds after this pass.
`vectors`	body	integer (int64)	—	Vectors is how many of those chunks carry an embedding.

Failure carries the platform error shape — see Errors.

MCP reaches code through the code tool, which names its 7 operations with its own verbs — this one among them, under a name only MCP declares. describe explains any of them:

curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "describe",
         "arguments": {
           "op": "get_code_ask"
         }
       }
     }'
