Unmeasured means there is not enough evidence to decide. How these checks work

Inspect individual checks 22 recorded

Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 779 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name easycircuit.

  • Pass
    Lists tools

    tools/list returned 7 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 779 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 779 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Fail
    Parameters documented

    8 of 22 parameters have a description (36%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-10-29T22:01:44.63825Z, within 180 days.

  • Not measured
    Open-source licence

    No GitHub repository to ask about a licence.

Capabilities

Tools 7

catalog_summary

Counts catalog parts by status and role.

Discovered
check_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.

Discovered
get_part

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

Discovered
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.

Discovered
get_part_pins

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.

Discovered
save_design

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.

Discovered
search_parts

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.
