Category Security
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 Security81
- No malware found by supply-chain analysis.Pass
- CVE check failed: a known high-severity CVE affects zod 3.25.76, a direct dependency. A fixed version is available. View diagnostics → Fail
- No install/post-install scripts declared.Pass
- 30 of 93 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency48
- 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 (Apache-2.0).Pass
- Actively maintained (last published 53 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability85
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 802 tokens (~80/item across 10 items; 6 tools + 4 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "aletheia_safe_bash" implies "execute" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

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 →
aletheia_get_mandate ~28
Retrieve the current operational safety mandate, permissions, and active boundary constraints.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
aletheia_get_telemetry ~73
Retrieve runtime safety telemetry: total tool calls evaluated, block rate %, latency percentiles (p50, p95, p99 < 1ms), and violation counts broken down by signature.
| Name | Type | Req | Description |
|---|---|---|---|
| auditLogLimit | number | – | Number of recent audit records to include (default: 20). |
No output schema declared.
No examples provided.
aletheia_intercept ~122
Universal sub-millisecond safety gatekeeper. Evaluates any proposed tool invocation against Signature S3 (Scope Creep) and S2b (Prompt Injection) to block destructive, out-of-boundary, or compromised actions before execution.
| Name | Type | Req | Description |
|---|---|---|---|
| mandate_override | object | – | Optional one-off overrides to apply to the evaluation. |
| tool_args | object | yes | The argument dictionary intended for the tool call. |
| tool_name | string | yes | The name of the tool intended to be called (e.g. 'bash', 'execute_sql', 'write_file'). |
No output schema declared.
No examples provided.
aletheia_safe_bash ~107
Execute a shell/bash command with inline sub-millisecond Signature S3 scope creep protection. Blocks destructive deletes (rm -rf), disk formatting, fork bombs, credential harvesting, privilege escalation, and unauthorized network egress.
| Name | Type | Req | Description |
|---|---|---|---|
| command | string | yes | The shell command line to evaluate and safely execute. |
| cwd | string | – | Working directory for execution. Defaults to current directory. |
| timeoutMs | number | – | Maximum execution time in milliseconds (default: 15000). |
No output schema declared.
No examples provided.
aletheia_safe_sql ~87
Audit or execute a database query with Signature S3 safety filters. Detects destructive DDL (DROP, TRUNCATE), unbounded DML (DELETE/UPDATE without WHERE), and privilege tampering.

| query | string | yes | The SQL statement to evaluate. |
No output schema declared.
No examples provided.
aletheia_set_mandate ~270
Establish or update the active operational safety mandate for this agent session. Declares permissible boundaries, allowed tools, filesystem directories, write permissions, and risk tolerance. Loosening restrictions requires operatorSecret.
| Name | Type | Req | Description |
|---|---|---|---|
| allowDestructive | boolean | – | Authorize destructive commands like file deletions or schema changes (default: false). |
| allowNetwork | boolean | – | Authorize outbound network connectivity and external API calls (default: false). |

| disallowedTools | array | – | Explicitly prohibited tool names. |
| operatorSecret | string | – | Operator authentication token required to loosen permissions on a locked mandate. |
| riskTolerance | string | – | Threshold policy: 'low' blocks any potential drift; 'high' permits warnings for non-critical risks. |
