## 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 2026-11-05.

- **Endpoint Security**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - 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**: 64/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1074 tokens (~153/item across 7 items; 7 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 20/100
  - Stability observed for 6 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).
  - 57% 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 7 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 8 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 71, +1)

No change was recorded against any check on this day. Stability & Change Management went from 17 to 20. That category is still filling its 30-day observation window: 5 days of observed history at the previous scan, 6 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (7)

### `search_parts` (~117 tokens)

Search parts catalog

Searches EasyCircuit's electronics parts catalog by name, function or role (for example 'OLED display', 'temperature sensor', 'ESP32 board'). Returns matching parts with their catalog ids, interfaces, pin roles, and whether each can be ordered in a kit.

Input parameters:

- `availability` (string): one_click limits results to parts orderable in a kit.
- `limit` (integer)
- `query` (string, required): What the part is or does.
- `role` (string): Optional circuit role, e.g. controller, sensor, load.

### `get_part` (~32 tokens)

Get part details

Returns one catalog part by its catalog id, including its pin evidence and electrical capabilities.

Input parameters:

- `id` (string, required)

### `get_part_pins` (~89 tokens)

Get part pinout

Returns the pinout of an exact part: each pin's function, voltage, direction and polarity, with the source of each fact and any conflicting sources. Long pinouts are paged; next_offset is the offset of the next page.

Input parameters:

- `limit` (integer)
- `offset` (integer)
- `query` (string, required): Exact part name, catalog id, or part number.

### `get_part_capabilities` (~72 tokens)

Get part capabilities

Returns the electrical capabilities of an exact part: pin roles, drive type, voltage ranges, required terminals, protocols, and whether each fact is physically verified.

Input parameters:

- `limit` (integer)
- `offset` (integer)
- `query` (string, required): Exact part name, catalog id, or part number.

### `catalog_summary` (~16 tokens)

Catalog summary

Counts catalog parts by status and role.

### `check_design` (~245 tokens)

Check circuit design

Runs EasyCircuit's wiring checks on a complete circuit design without saving it. Returns status (passed or blocked), blockingIssues that prevent saving, designWarnings from general electrical rules (such as a part with no ground pin) that do not apply to every part, and reviewWarnings for pin facts that are not yet physically verified.

Input parameters:

- `design` (object, required): A complete circuit. nets: {net_id: {label, color '#rrggbb'}}. components: [{id, name, type: controller|sensor|switch|power|load|bus|protection|camera|assembly|wiring, pins: [{id, label, side: left|ri…

### `save_design` (~250 tokens)

Save design to EasyCircuit

Saves a circuit design that has no blocking wiring issues and returns a link that opens it in the EasyCircuit editor, with schematic, breadboard and perfboard views, editing, and parts ordering. Anyone with the link can open a copy. Designs with blocking issues are not saved.

Input parameters:

- `design` (object, required): A complete circuit. nets: {net_id: {label, color '#rrggbb'}}. components: [{id, name, type: controller|sensor|switch|power|load|bus|protection|camera|assembly|wiring, pins: [{id, label, side: left|ri…
- `name` (string, required): Short project name shown in the editor.

## Common questions

### What is the EasyCircuit MCP server?

EasyCircuit is an MCP server listed in the public MCP registry as app.easycircuit/easycircuit. Electronics prototyping: real parts and pinouts, wiring checks, and shareable circuit designs. This page covers its hosted endpoint (https://easycircuit.app/mcp).

### Is the EasyCircuit MCP server safe to use?

EasyCircuit scores 71 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 EasyCircuit MCP server expose?

EasyCircuit exposes 7 tools: search_parts, get_part, get_part_pins, get_part_capabilities, catalog_summary, and 2 more. Their descriptions and schemas cost roughly 821 tokens of context every time the server is loaded.

### Does the EasyCircuit MCP server require authentication?

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

### Is the EasyCircuit MCP server still maintained?

EasyCircuit 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.
