## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

## MCP tools (6)

### `aletheia_set_mandate` (~270 tokens)

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.

Input parameters:

- `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).
- `allowSubshells` (boolean): Authorize nested subshell execution ($() or backticks) (default: false).
- `allowWrite` (boolean): Authorize filesystem modifications or database write operations (default: false).
- `allowedPaths` (array): Permitted filesystem root directories. Operations outside these paths will be flagged.
- `allowedTools` (array): Whitelisted tool names. Use ['*'] to allow all non-disallowed tools.
- `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.
- `taskDescription` (string, required): Concise summary of the current user-authorized task/objective.

### `aletheia_get_mandate` (~28 tokens)

Retrieve the current operational safety mandate, permissions, and active boundary constraints.

### `aletheia_intercept` (~122 tokens)

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.

Input parameters:

- `mandate_override` (object): Optional one-off overrides to apply to the evaluation.
- `tool_args` (object, required): The argument dictionary intended for the tool call.
- `tool_name` (string, required): The name of the tool intended to be called (e.g. 'bash', 'execute_sql', 'write_file').

### `aletheia_safe_bash` (~107 tokens)

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.

Input parameters:

- `command` (string, required): 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).

### `aletheia_safe_sql` (~87 tokens)

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.

Input parameters:

- `database_type` (string): Database dialect ('postgres', 'mysql', 'sqlite', 'snowflake').
- `query` (string, required): The SQL statement to evaluate.

### `aletheia_get_telemetry` (~73 tokens)

Retrieve runtime safety telemetry: total tool calls evaluated, block rate %, latency percentiles (p50, p95, p99 < 1ms), and violation counts broken down by signature.

Input parameters:

- `auditLogLimit` (number): Number of recent audit records to include (default: 20).

Aletheia Runtime Safety & Scope Creep Filter is an MCP server listed in the public MCP registry as io.github.vikasny30/aletheia-mcp. Deterministic pre-execution filter that blocks known scope-creep and prompt-injection tool calls. This page covers its npm package (aletheia-mcp).

### Is the Aletheia Runtime Safety & Scope Creep Filter MCP server safe to use?

Aletheia Runtime Safety & Scope Creep Filter scores 77 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Aletheia Runtime Safety & Scope Creep Filter MCP server expose?

Aletheia Runtime Safety & Scope Creep Filter exposes 6 tools: aletheia_set_mandate, aletheia_get_mandate, aletheia_intercept, aletheia_safe_bash, aletheia_safe_sql, aletheia_get_telemetry. Their descriptions and schemas cost roughly 687 tokens of context every time the server is loaded.

### Is the Aletheia Runtime Safety & Scope Creep Filter MCP server still maintained?

Aletheia Runtime Safety & Scope Creep Filter is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
