## 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)

- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-05 (score 83, +1)

No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (4)

### `roll_table` (~344 tokens)

Pipeworx original random tables: roll one or more entries from a built-in table — encounters_fantasy, encounters_scifi, encounters_modern, loot, weather, complication, npc_personality, npc_secret, npc_occupation, plot_hook, tavern, rumour, settlement_quirk, npc_full. Entries may contain {{table:<id>}} references to OTHER built-in tables, resolved recursively (up to 6 levels deep) — the response gives both the raw entry text and the fully resolved text. Optional seed makes the roll reproducible (same seed + arguments = same result; the seed used is always returned). Optional session_id draws without replacement across repeated calls (hosted only, via the gateway's shared KV) — pass none to get an ordinary independent weighted roll every time, or pass any string to start tracking a no-repeat session (the response returns the real session_id to reuse). No text from any commercial RPG product — every table and entry is written for Pipeworx.

Input parameters:

- `count` (number): How many entries to roll, 1-20 (default 1).
- `seed` (string): Optional seed for a reproducible roll. Omit for fresh randomness; the seed actually used is always returned.
- `session_id` (string): Optional. Omit for an ordinary independent weighted roll. Pass a session_id (your own first time, or one returned by a previous call) to draw without replacement across calls — hosted only.
- `table` (string, required): Built-in table id, e.g. "loot", "npc_full", "encounters_fantasy". Call list_random_tables to see every id.

### `roll_custom_table` (~209 tokens)

Pipeworx original random tables: roll one or more entries from a table YOU supply — bring your own weighted list of { text, weight? } and get back a reproducible weighted draw. Entries may contain {{table:<id>}} references to Pipeworx's BUILT-IN random tables (e.g. "{{table:npc_personality}}"), resolved recursively (up to 6 levels deep). Optional seed makes the roll reproducible; the seed used is always returned. No session support for custom tables — use roll_table for session-tracked built-in tables.

Input parameters:

- `count` (number): How many entries to roll, 1-20 (default 1).
- `entries` (array, required): Your table: a non-empty array of { text: string, weight?: number > 0 (default 1) }. Up to 500 entries.
- `seed` (string): Optional seed for a reproducible roll. Omit for fresh randomness; the seed actually used is always returned.

### `list_random_tables` (~107 tokens)

Pipeworx original random tables: list every built-in table id, title, genre and entry count, optionally filtered to one genre ("fantasy", "scifi" or "modern"). Genre-agnostic tables (loot, weather, npc_*, complication, plot_hook, rumour, settlement_quirk, npc_full) are included under every genre filter, since they apply regardless of setting.

Input parameters:

- `genre` (string): Optional genre filter. Omit to list every table.

### `get_random_table` (~102 tokens)

Pipeworx original random tables: fetch one built-in table in full — its title, genre, description, and every raw entry (text + weight) — without rolling. Entry text may contain unresolved {{table:<id>}} references; roll_table resolves those at roll time.

Input parameters:

- `table` (string, required): Built-in table id, e.g. "loot", "npc_full", "encounters_fantasy". Call list_random_tables to see every id.

## Common questions

### What is the Random Tables MCP server?

Random Tables is an MCP server listed in the public MCP registry as io.github.pipeworx-io/random-tables. random-tables, Pipeworx original composable random tables for tabletop and narrative play… This page covers its npm package (@pipeworx/mcp-random-tables).

### Is the Random Tables MCP server safe to use?

Random Tables scores 83 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. 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 Random Tables MCP server expose?

Random Tables exposes 4 tools: roll_table, roll_custom_table, list_random_tables, get_random_table. Their descriptions and schemas cost roughly 762 tokens of context every time the server is loaded.

### Is the Random Tables MCP server still maintained?

Random Tables is still listed as active in the MCP registry. We last reached this channel on 5 November 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 Random Tables MCP server under?

Random Tables declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Random Tables MCP server?

VerifyMCP ran 16 checks on Random Tables, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
