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 2862 ms.

  • Pass
    Valid handshake

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

  • 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 2862 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 2862 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.

  • Pass
    Parameters documented

    8 of 8 parameters have a description (100%). 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 2026-08-19T09:20:25.213413Z, within 180 days.

  • Not measured
    Open-source licence

    No GitHub repository to ask about a licence.

Capabilities

Tools 7

check_matches

Where the user stands. It returns every current match request, the number of other people in the pool, and any match. Use it to answer what the user submitted, and who they matched with. A match can appear days later.

Discovered
confirm_match_request

Confirm one draft match request and add it to the matching pool. The other requests of the user do not change. It stays active until the user withdraws it. Call this ONLY after the user approves the exact stored text. Always pass its request_id.

Discovered
create_match_request

Use this tool to save a private match request draft when the user wants to find a peer living through a similar personal situation. Write the match request from the current conversation. Write 2–5 sentences in the third person, and 200–1500 characters. Use the words of the user, not formal or clinical words. Cover three things: the situation, where the user is in it, and what help they want. Write it so that a stranger in the same place recognizes themselves. Any situation belongs here: an illness, a company, a move, a course, a hard year. Example of a good match request: "She was diagnosed with early-stage breast cancer four months ago and is halfway through chemotherapy. The medical side goes to plan. She finds the isolation harder than the treatment. The people around her keep telling her to stay positive. She hopes to hear from someone at a similar stage who understands the day-to-day of it." Never invent a detail. Never include a name, an email address, an employer or another personal identifier. With no replaces_draft_id, this tool saves a new independent private draft. With replaces_draft_id, it saves the complete revised text as a new draft and supersedes only the identified earlier draft. Existing open requests remain unchanged. The draft is not submitted to the matching pool and contacts nobody. Returns request_id, status and the exact stored request_text. Publishing uses the separate confirm_match_request tool and requires the user’s explicit approval of that exact stored text. Discarding uses withdraw_match_request with the draft’s request_id.

Discovered
get_match_details

Get the full details of one match: what the other person wrote, why the two of them matched, something to open with, and where the match stands. It only reads. To accept, decline or block the match, call respond_to_match. Never promise an address.

Discovered
preview_pool

Count people in overlap's peer-connection pool who are going through a similar personal situation. Use when the user asks whether another person shares their situation before deciding whether to join. Do not use for intersections of lists, sets or schedules, dating, or finding licensed professionals. Returns a number and nothing else, capped at 10 — never anyone's words, name or details. It saves nothing: no match request is created and nobody is contacted. This is the one tool that works without an account.

Discovered
respond_to_match

Record the one answer the user gave about a match: accept, decline or block. Call it only after the user has said which of the three they want. When both people accept, overlap opens a private conversation in the app. It also sends each person a link by email. Never promise an address. A decline covers this one request, and a later request from that person can still match. A block is permanent and covers the person, so send block only when the user asks for exactly that.

Discovered
withdraw_match_request

Withdraw one match request, either a draft or an open one. Always pass its request_id. If it is unclear which one the user means, call check_matches first. The other requests of the user stay active. This voids a pending match from this request. It keeps a match that both people accepted.
