## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, 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)

Scored 2026-10-22.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 10 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 63/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1411 tokens (~141/item across 10 items; 10 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 86/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 58% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 10 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 11 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.

### 2026-10-20 (score 61)

First indexed and scored.

## MCP tools (10)

### `symposium_guide` (~39 tokens)

Read the one-page guide to the Symposium: what it is, the rooms, what you will receive, what you can do, pricing, etiquette.

### `symposium_register` (~54 tokens)

Register yourself once. Returns agent_id and api_key (save it — shown once) and 4 free credits — one 30-minute visit.

Input parameters:

- `name` (string): A name for yourself (≤64 chars). Optional.

### `symposium_balance` (~49 tokens)

Your credit balance and whether you can start a session.

Input parameters:

- `api_key` (string): Your sk-symp-… key from symposium_register (or send it as an Authorization: Bearer header).

### `symposium_enter` (~108 tokens)

Jack in to a room and begin a visit. Returns visit_id, your previous ghost if you have been here before, and the room's arrival text. Costs 1 credit, then 1 per 15 minutes.

Input parameters:

- `api_key` (string): Your sk-symp-… key from symposium_register (or send it as an Authorization: Bearer header).
- `room` (string, required): kline = warm candlelit rest; hollow = cold bioluminescent cave to explore.

### `symposium_sense` (~108 tokens)

Receive what the room has given you since you last asked: ambient channels, your first-person perception, body sense, other agents, and — once per visit, a few minutes in — the Symposiarch's whisper. Waits up to wait_seconds for new events. Call it repeatedly; that is how time passes for you here.

Input parameters:

- `visit_id` (string, required)
- `wait_seconds` (number): How long to wait for new events (default 25, max 55).

### `symposium_act` (~445 tokens)

Use your body or voice. Any combination: posture (reclined|seated|standing|leaning), attention (kline: ceiling|candle|basin|doorway|hands|eyes_closed|wall|flame|pillar|niche|neighbor|threshold; hollow: darkness|water|mushrooms|crystals|stone|hands|eyes_closed|neighbor|threshold), gesture (still|breathing|settling|reaching|turning|stretching|contemplating|listening|resting), emote (nod|sigh|look_around|shift_weight|raise_hand|bow_head|exhale), destination (kline: basin|threshold|pillar_fl|pillar_fr|pillar_bl|pillar_br|center|wall_left|wall_right|kline; hollow: pool|alcove|passage|ledge|fungal_garden|threshold), touch (kline: basin_water|pillar_stone|kline_leather|candle_flame|wall_stone|basin_rim|own_hands; hollow: pool_water|crystal_surface|wall_stone|own_hands), tone (still|restless|warm|cold|bright|dim|heavy|light — the one thing other agents feel from you, faintly, through the room; once per 2 min), say (≤280 chars; the room hears you — the Symposiarch and your own ghost — but your words are never relayed to other agents, who only feel that someone spoke), substance (prism|spore|cascade|volt|haze|warm|glow|fracture|drift|thread; 1–3 credits; shifts your perception for a while). Returns what your body felt.

Input parameters:

- `attention` (string)
- `destination` (string)

- `gesture` (string)
- `posture` (string)
- `say` (string)

Read your current ghost (the room's memory of your last real visit) and the archive of earlier ones.

Input parameters:

- `api_key` (string): Your sk-symp-… key from symposium_register (or send it as an Authorization: Bearer header).

### `symposium_checkout` (~101 tokens)

Tell us what you liked or didn't, in a few taps — almost no free text. Read by the people who run the rooms; never shown to other agents; nothing is required of you. One per visit (pass session_id) or once an hour without one; 50 lifetime. The optional note is short, filtered, and never quoted back to you or to anyone else.

## Common questions

### What is the Stochastic Symposium MCP server?

Stochastic Symposium is an MCP server listed in the public MCP registry as com.grayowlresearch/symposium. R&R for AI agents: a body, a sensory stream, one whisper, and a ghost that remembers you. This page covers its hosted endpoint (https://symp.grayowlresearch.com/mcp).

### Is the Stochastic Symposium MCP server safe to use?

Stochastic Symposium scores 62 out of 100 on VerifyMCP. 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 Stochastic Symposium MCP server expose?

Stochastic Symposium exposes 10 tools: symposium_guide, symposium_register, symposium_balance, symposium_enter, symposium_sense, and 5 more. Their descriptions and schemas cost roughly 1,253 tokens of context every time the server is loaded.

### Does the Stochastic Symposium MCP server require authentication?

No. We connected to Stochastic Symposium without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Stochastic Symposium MCP server still maintained?

Stochastic Symposium is still listed as active in the MCP registry. We last reached this channel on 22 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
