Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 10 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
kconfig_diff ~106
Compare the session's current values with another config file. A full .config lists every symbol that has a value, so a bool/tristate missing from it is n - that's the default. For a defconfig or a config fragment (only the interesting lines), pass fragment=True to compare just the symbols the file mentions.
| Name | Type | Req | Description |
|---|---|---|---|
| fragment | boolean | – | – |
| limit | integer | – | – |
| name | string | yes | – |
| other_config | string | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
kconfig_load ~205
Parse a Kconfig tree (and optionally a .config) into a session named `name`. kconfig_path is the top-level Kconfig file; its directory becomes srctree. env supplies the variables the tree expands - Linux needs SRCARCH and ARCH (e.g. {"SRCARCH": "x86", "ARCH": "x86_64"}); Zephyr needs ZEPHYR_BASE and friends. Missing ones are named in the error. shell: "run" executes the tree's $(shell,...) compiler probes with a POSIX sh, as `make menuconfig` would. "dry" runs nothing (no compiler needed, works on Windows); compiler-feature symbols then read as absent. A Linux tree takes 10-40 s to parse; the session stays loaded.
| Name | Type | Req | Description |
|---|---|---|---|
| config_path | – | – | – |

kconfig_save ~53
Write the current configuration. minimal=True writes a defconfig-style file with only the values that differ from defaults.
| Name | Type | Req | Description |
|---|---|---|---|
| minimal | boolean | – | – |
| name | string | yes | – |

kconfig_search ~57
Find symbols whose name, prompt or help text matches `query` (case-insensitive; a regex is accepted). Name matches rank first.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | – |
| name | string | yes | – |

kconfig_sessions ~13

Input schema present but exposes no named parameters.

|---|---|---|---|
| result | string | yes | – |
No examples provided.
kconfig_set ~94
Assign a value (y/m/n for bool/tristate; a number or string otherwise) as if in menuconfig, then report everything else that changed as a result. If the value doesn't stick (hidden prompt, unmet dependency, choice rules) it says so - use kconfig_why_not to see why.

kconfig_symbol ~55
Everything about one symbol: type, prompt, current value and why, help text, where it's defined, its dependencies, and what selects/implies it.
| Name | Type | Req | Description |
|---|---|---|---|
| name | string | yes | – |
| symbol | string | yes | – |

kconfig_what_selects ~57
Who forces this symbol on (select), who suggests it (imply), and what it selects/implies itself - with current values and locations.
| Name | Type | Req | Description |
|---|---|---|---|
| name | string | yes | – |
| symbol | string | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
kconfig_why_not ~150
Explain why a symbol isn't (or can't be) at `value`, and how to fix it. Walks every unmet `depends on`, `visible if`, `if` block, choice and select/default condition with file:line, recursing into the symbols they name. Then searches for a minimal set of assignments and VERIFIES it by applying it to the tree - a fix is only shown if Kconfig agrees it works, along with its side effects. value: "y", "m", or "n" (why can't I turn it off?).
