### 2026-10-14 (score 39)

First indexed and scored.

## MCP tools (16)

### `hexvero_open` (~47 tokens)

Open target

Register a local file or directory for analysis. Returns its id, size, hash and detected format. Ids are stable per content.

Input parameters:

- `path` (string, required): Absolute or relative path

### `hexvero_list` (~16 tokens)

List targets

List targets opened in this session.

### `hexvero_close` (~32 tokens)

Close target

Release a target and its retained analysis.

Input parameters:

- `targetId` (string, required): Target id returned by hexvero_open

### `hexvero_analyze` (~265 tokens)

Analyze target

Run the built-in analyzer for the target's format (ELF/PE/Mach-O, Go, .NET, WASM, EVM, SQLite, plist, APK, ZIP, Electron ASAR, JavaScript apps, source maps, HAR). Returns a summary, findings with confidence, limitations, a compact overview and the collections available for paging. Large JavaScript apps are read in batches: when `complete` is false, `coverage` says how many files are unread and every list covers the scanned part only; call again with scan to read more.

Input parameters:

- `batch` (integer): JavaScript apps only: files per batch (default 5000)
- `detail` (string): overview size: brief (default) lists only counts, full adds samples of every list
- `fresh` (boolean): JavaScript apps only: discard the stored scan first; combines with scan
- `include` (array): JavaScript apps only: read the unread files under these paths (prefix or * pattern)
- `scan` (string): JavaScript apps only: continue = read the next batch of unread files, all = read every unread file, fresh = discard the stored scan and start again
- `targetId` (string, required): Target id returned by hexvero_open

### `hexvero_collection` (~183 tokens)

Page a collection

Page through one named list from the analysis, e.g. symbols, imports, exports, sections, libraries, types, methods, pinvokes, selectors, instructions, tables, columns, requests, endpoints, permissions, components, modules, edges, ipcChannels, findings. Use hexvero_analyze to see which exist.

Input parameters:

- `collection` (string, required)
- `limit` (integer): Items per page (default 100)
- `maxBytes` (integer): Hard upper bound for the serialized page in bytes (default 262144). A page reports next, bytes and, for an item cut to fit, itemTruncated + itemBytes
- `offset` (integer): First item index (default 0)
- `targetId` (string, required): Target id returned by hexvero_open
- `text` (string): Case-insensitive substring filter on each item

### `hexvero_strings` (~172 tokens)

Strings

Printable ASCII (and optional UTF-16LE) strings with offsets and tags (url, path, email, ip, format, secret-ish, base64-ish).

Input parameters:

- `limit` (integer): Items per page (default 100)
- `maxBytes` (integer): Hard upper bound for the serialized page in bytes (default 262144). A page reports next, bytes and, for an item cut to fit, itemTruncated + itemBytes
- `minLength` (integer)
- `offset` (integer): First item index (default 0)
- `tag` (string): Only strings carrying this tag
- `targetId` (string, required): Target id returned by hexvero_open
- `text` (string): Case-insensitive substring filter on each item
- `utf16` (boolean)

### `hexvero_bytes` (~59 tokens)

Read bytes

Read a bounded window (max 64 KiB) of the target as hex plus an ASCII gutter.

Input parameters:

- `length` (integer, required)
- `offset` (integer, required)
- `targetId` (string, required): Target id returned by hexvero_open

### `hexvero_export` (~81 tokens)

Export analysis

Write the complete analysis as JSON to a file and return its path and size. Use this instead of paging when you need everything.

Input parameters:

- `overwrite` (boolean): Replace an existing file (default false)
- `path` (string, required): Absolute destination file path; refused when the file exists
- `targetId` (string, required): Target id returned by hexvero_open

### `hexvero_recover` (~99 tokens)

Recover sources

Write recoverable sources into a new directory: the modules of a webpack/Rspack/browserify/esbuild bundle (one file each plus hexvero-bundle.json with requires/exports), or the original files embedded in a source map (sourcesContent). No engine needed; nothing is executed.

Input parameters:

- `outputDir` (string, required): Absent or empty directory to write into
- `targetId` (string, required): Target id returned by hexvero_open

### `hexvero_unknowns` (~153 tokens)

Unknowns ledger

Record a material question the investigation could not answer (with what was already checked), list open or resolved unknowns, or resolve one. Unknowns are exported with the analysis so reports never silently drop them.

Input parameters:

- `action` (string, required)
- `checked` (array): record: collections, offsets or tools already examined
- `id` (string): resolve: the unknown's id
- `limit` (integer)
- `offset` (integer)
- `question` (string): record: the open question
- `resolution` (string): resolve: what settled it, with evidence
- `status` (string): list: filter by status
- `targetId` (string): Target the question belongs to

### `hexvero_compare` (~265 tokens)

Compare collections

Diff one collection between two targets: added, removed, changed (with the fields that differ) and unchanged items, matched by key (auto-detected: name, channel, id, path, url, type+name … or pass key, a+b for composites). States completeness; unknown items are neither added nor removed. Each list pages on its own (list + offset). Without collection: counts per shared collection, to pick one.

Input parameters:

- `collection` (string)
- `ignore` (array): Fields to exclude from change detection, in addition to the position rule
- `key` (string): Item field used as identity (default: name, then JSON)
- `limit` (integer): Items per list in this answer (default 50 added/removed, 25 changed)
- `list` (string): Page only this list; offset applies to it (each list has its own next)
- `offset` (integer): With list: that list's next
- `strict` (boolean): Count every difference. Default false: address fields of native symbols/sections that only moved are reported as relocated, with samples
- `targetA` (string, required): Target id returned by hexvero_open
- `targetB` (string, required): Target id returned by hexvero_open

### `hexvero_check` (~155 tokens)

Check release policy

Apply a release policy (inline JSON or file) to two builds, as `hexvero check`: status pass, fail or incomplete, and findings paged by offset. Reads a baseline, never writes one.

Input parameters:

- `baselinePath` (string): Absolute path of a baseline file
- `format` (string): Default json
- `limit` (integer): Findings (default 100)
- `offset` (integer): First finding (default 0)
- `policy` (object): Policy JSON object
- `policyPath` (string): Or: absolute path of a policy file
- `targetA` (string, required): Target id returned by hexvero_open
- `targetB` (string, required): Target id returned by hexvero_open

### `hexvero_sourcemap` (~63 tokens)

Resolve source map position

Map a generated line/column of a source map target back to its original source, line, column and name.

Input parameters:

- `column` (integer, required)
- `line` (integer, required)
- `targetId` (string, required): Target id returned by hexvero_open

### `hexvero_providers` (~31 tokens)

Providers

Detect optional external engines (radare2/rizin, Ghidra) and the operations each supports.

### `hexvero_provider_run` (~129 tokens)

Run provider operation

Run one engine operation on a target: functions, disassemble, decompile, strings, imports, xrefs (references to an address), callers, callees, callgraph or search (names + strings). Output is bounded and cached.

Input parameters:

- `address` (string): Function address or symbol for disassemble/decompile/xrefs/callers/callees
- `operation` (string, required)
- `provider` (string, required)
- `targetId` (string, required): Target id returned by hexvero_open
- `text` (string): Needle for search
- `timeoutMs` (integer)

### `hexvero_call_graph` (~159 tokens)

Call graph

Bounded call-graph neighborhood around a function (callers, callees or both, by depth and node count), or the shortest call path from root to goal. One engine run per target, cached; levels state what was cut.

Input parameters:

- `direction` (string): Default callees
- `goal` (string): With goal: shortest path root → goal in the given direction instead
- `maxDepth` (integer): Hops from root (default 2)
- `maxNodes` (integer): Default 150
