How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- Runs hatchling.build at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
- 1 of 28 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 5 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability69
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 707 tokens (~88/item across 8 items; 8 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
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 8 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 9 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.
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

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 →
mort_check ~91
Type-check Mort code without building it (fast; needs no C compiler). Pass `source` (a whole program as text) and/or `files` (paths to .mx files compiled together as one program). Returns OK or the compiler's diagnostics with file:line:column and the offending source line.
| Name | Type | Req | Description |
|---|---|---|---|
| files | – | – | – |
| source | – | – | – |
| warn_unused | boolean | – | – |

| result | string | yes | – |
No examples provided.
mort_docs ~77
Search the Mort language specification and reference docs. Returns the best-matching sections, e.g. query="resource struct cleanup", "integer overflow", "slices", "error propagation ?". Requires MORT_HOME (a Mort checkout) since pip installs don't ship the docs.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | – |
| query | string | yes | – |
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
mort_emit_c ~79
Show the C that Mort generates for a program (useful to see what a construct compiles to, or to debug codegen). freestanding=True emits bare-metal C (no libc, no main) as used for the MORT OS kernel.
| Name | Type | Req | Description |
|---|---|---|---|

mort_examples ~46
List the compiler's bundled example programs, or show one by name. Examples are known-good Mort - a fast way to learn idioms. Needs MORT_HOME.

mort_run ~118
Compile Mort code to a native binary and run it, capturing its output. Needs a C compiler (cc/gcc/clang, or `pip install ziglang`). `stdin` is fed to the program, `args` are its command-line arguments, and it is killed after timeout_s. Reports compile errors the same way mort_check does.

mort_std ~68
Look up the standard library. With no module: list every std module. With a module (e.g. "strings" or "std.vec"): its public functions, structs and enums with exact signatures and doc comments, read from the installed compiler's source.

io.github.0xmortuex/mort-mcp exposes 8 tools: mort_version, mort_check, mort_run, mort_emit_c, mort_format, and 3 more. Their descriptions and schemas cost roughly 535 tokens of context every time the server is loaded.
Is the io.github.0xmortuex/mort-mcp server still maintained?
io.github.0xmortuex/mort-mcp is still listed as active in the MCP registry. We last reached this channel on 17 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the io.github.0xmortuex/mort-mcp server under?
io.github.0xmortuex/mort-mcp declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
