Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 335 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name open-call-portals.

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

  • Not measured
    Consistent (p95)

    95th percentile 335 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.

  • Fail
    Valid input schemas

    1 tools are missing an object inputSchema.

  • Fail
    Parameters documented

    27 of 34 parameters have a description (79%). The bar is 80%.

  • Fail
    Safety hints

    7 tools set neither readOnlyHint nor destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Not measured
    Website matches publisher

    This namespace is not a reverse domain, so the website comparison does not apply.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Fail
    Repo owner matches

    The GitHub repository owner does not match the namespace login.

  • Pass

Capabilities

Tools 7

get_opportunity

Look up one opportunity by its exact public UI reference (for example DJ-3128) before making any claim about it. Returns only an active, non-deleted, non-membership, non-partner public listing and its allowedResponderRoles. State only fields in the live result; missing means not provided. Never invent volume, frequency, or competition.

Discovered
get_platform_schema

Returns the Open Call Portals discovery contract: portal IDs, field value options, MCP server details, and read-only search metadata. Call this first for autodiscovery before filtering searches.

Discovered
prepare_listing_form

Validate a versioned, allowlisted listing-form prefill and return the canonical create-form URL. It supports every mounted form advertised by get_platform_schema (39 portal forms plus live events); the exact portal-specific fields, posting roles, and value shapes are declared in this tool's schema. This is a no-write handoff: it never creates a draft, sends email, verifies a code, or publishes. Do not include email addresses, verification codes, tokens, session IDs, credentials, contact data, or unrecognized fields.

Discovered
prepare_response_form

For an exact active DJ opportunity only, validate a small response prefill and return the normal editable DJ form URL. This is a no-write handoff: AI may prepare it, but the human supplies identity/contact, consent and verification, then clicks send. It never creates drafts, sends email, verifies, publishes, creates alerts, or uses webhooks. Do not include names, email, phone, credentials, tokens, consent, verification codes, or submission fields.

Discovered
search_availability

Use this first for buyer-side requests to find, hire, or book talent, crew, suppliers, or services: 'I need a live band in St Kilda', 'find a DJ near Amsterdam', or 'event crew for hire'. For 'I need a live band in St Kilda', use portalId='lb-availability' and location='St Kilda'. Location hierarchy allows broader Melbourne availability to match St Kilda and labels it as a parent-area match. Do NOT use this when the speaker is the talent seeking work, e.g. 'I am a DJ looking for gigs/work'; use search_open_calls for that perspective. Do NOT use this when the user explicitly says 'open call' or asks to post/find/search open calls; that explicit wording takes priority. If availability returns zero, offer to post an open call; never claim a match exists. Search availability listings posted by performers, crew, and service providers who are actively seeking bookings. These are the supply side of the platform — DJs, bands, comedians, artists, event crew, and more advertising their availability for a date range or location. Complement to search_open_calls (demand side).

Discovered
search_live_events

Use when the user asks to find, show, attend, watch, visit, or buy tickets for an event or session—not when they need to hire talent. For example, 'find an analogue listening session in Melbourne' uses this tool; 'analogue listening sessions looking for organisers' uses search_open_calls. Search first-party upcoming live events submitted directly to the Open Call Portals Live Events Map. Includes DJ sets, live bands, comedy nights, and more with geo coordinates (lat/lng), ticketing info, source links, and event start/end times. All events are future or currently in progress.

Discovered
search_open_calls

Use this when talent, crew, suppliers, or service providers are looking for posted work: gigs, jobs, opportunities, vacancies, slots, bookings, wanted/needed listings, or open calls. Treat those words as search intent—not as genre/type filters. For example, 'DJ gig Amsterdam', 'DJ opportunity in Amsterdam', 'DJ needed listings Amsterdam', and 'I am a DJ looking for work in Amsterdam' all use search_open_calls with portalId='dj' and location='Amsterdam'. Explicit wording such as 'post/find/search open calls' always uses this tool, even when the speaker is a venue manager or private event host. Impersonal posted requirements such as 'analog listening sessions looking for organisers' also use this tool. Do NOT use this as the first choice when a buyer says 'I need/find/want to hire/book a DJ or live band'; call search_availability for that buyer-side intent instead. Venues and event hosts post open calls to find DJs, live bands, comedians, artists, content creators, event crew, solopreneurs, game hosts, casting talent, and more. Returns structured listings with location, genre, type, close date, and a canonical URL. Each result includes allowedResponderRoles so callers can explain who may apply through the listing's canonical web page. All results are PII-free.
