## 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 2026-09-29.

- **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 8 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**: 77/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 439 tokens (~54/item across 8 items; 8 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 81/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 43% 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 8 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## Install

### How do I install the science.executable/executable-science MCP server?

science.executable/executable-science is a hosted endpoint at https://executable.science/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## 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.

### 2026-09-28 (score 66, 0)

- [functional] We updated how we score, so this day's move reflects our rubric, not a change to the server

### 2026-09-27 (score 66, +1)

- [security] The server rewrote its instructions, which are the text every model session reads
- [functional regression] Schema quality: 296 → 439
- [functional regression] Tool coverage: 60% → 43%
- [functional] Server version: 0.1.0 → 0.2.0
- [functional] New tool “get_starter_source”
- [functional] New tool “get_starter_study”
- [functional] New tool “list_starter_studies”

### 2026-09-25 (score 65, 0)

- [functional] We updated how we score, so this day's move reflects our rubric, not a change to the server

### 2026-09-24 (score 65, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-09-23 (score 64, 0)

- [functional improvement] Stability: unverified → 0.03

### 2026-09-22 (score 64)

First indexed and scored.

## MCP tools (8)

### `get_resource` (~35 tokens)

Read one catalogued public resource by its identifier, including its recorded rights and provenance.

Input parameters:

- `resource_id` (string, required): Catalogue identifier.

### `get_starter_source` (~50 tokens)

Download one original licensed starter ZIP as base64 with its SHA-256 and rights. Source has not run or been verified; submitting it still requires isolated ingestion.

Input parameters:

- `study_id` (string, required)

### `get_starter_study` (~40 tokens)

Read one licensed starter study's frozen inputs, archive digest, environment, expected interpretation and unrun status.

Input parameters:

- `study_id` (string, required)

### `get_task_template` (~56 tokens)

Read one frozen task template in full: its question, inputs, assumptions, comparison basis, stated limitations and revision digest. The digest pins the exact revision an attempt was prepared against.

Input parameters:

- `task_id` (string, required): Task template identifier.

### `list_starter_studies` (~33 tokens)

List original downloadable source studies with explicit licenses, archive digests, pinned catalog environments and unrun evidence status.

### `list_task_templates` (~32 tokens)

List the bounded, frozen questions this platform publishes for attempt. Each carries a revision digest and its own stated limitations.

### `platform_status` (~41 tokens)

Report the current stage and, for every capability, whether it is available and the stated reason. Several capabilities are gated; this tool is the authoritative answer on which.

### `search_resources` (~54 tokens)

Search the public catalogue of datasets, software packages, published articles, method references and original experiments by title.

Input parameters:

- `kind` (string)
- `limit` (integer)
- `query` (string): Words matched against titles.

science.executable/executable-science is an MCP server listed in the public MCP registry as science.executable/executable-science. Read-only research pilot catalogue: task templates, resources, starter studies, capability status. This page covers its hosted endpoint (https://executable.science/api/mcp).

### Is the science.executable/executable-science MCP server safe to use?

science.executable/executable-science scores 66 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 science.executable/executable-science MCP server expose?

science.executable/executable-science exposes 8 tools: get_resource, get_starter_source, get_starter_study, get_task_template, list_starter_studies, and 3 more. Their descriptions and schemas cost roughly 341 tokens of context every time the server is loaded.

### Does the science.executable/executable-science MCP server require authentication?

No. We connected to science.executable/executable-science without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the science.executable/executable-science MCP server still maintained?

science.executable/executable-science is still listed as active in the MCP registry. We last reached this channel on 29 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
