Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 600 ms.

  • Pass
    Valid handshake

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

  • Pass
    Lists tools

    tools/list returned 10 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 600 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 600 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

    6 of 30 parameters have a description (20%). 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 2026-10-27T06:06:15.817087Z, within 180 days.

Capabilities

Tools 10

build_unsigned_trade

Build a fresh Solana mainnet v0 transaction and quote for a Limitless bonding-curve buy/sell. Every signature is zero. The caller must independently validate, simulate, sign and broadcast. No keys accepted. Network fees and possible account/escrow rent are extra.

Discovered
get_listing_status

Read public token listing discovery. To access creator request receipts, provide wallet; without proof, returns an unsigned message to sign locally. Repeat with issuedAt and signature. The same website backend verifies creator ownership.

Discovered
get_portfolio

Read the public indexed portfolio for a Solana wallet. This is the API holdings view; it may omit assets or lag chain state. No auth or wallet ownership is requested.

Discovered
get_prices

Get SOL/USD and indexed token prices for up to 20 mints. These are display prices, not executable quotes; missing token prices are explicit.

Discovered
get_token_detail

Read indexed metadata, status, prices and available statistics for a Solana mint.

Discovered
get_tokens

List/search tokens from the public Limitless API, including pending tokens. Pagination is upstream pagination; status is not proof of tradeability.

Discovered
get_trade_quote

Quote a buy or sell on an existing Solana mainnet Limitless bonding curve from current on-chain reserves and fees. No signing or submission. Unsupported pending, completed/AMM and EVM trades return errors.

Discovered
get_trending

Return the public Limitless discovery feed sorted by its upstream trending score. Pending tokens may appear.

Discovered
list_listing_targets

Read the shared Get listed catalog: supported destinations, manual requirements and paid options. Listing availability is independent of trading. No payment or submission.

Discovered
submit_listing

Prepare or dispatch supported listing requests through the website’s shared Get listed backend. Requires proof from the token creator. Omit signature and issuedAt to get the exact message to sign locally, then repeat with both. Manual forms remain action_required; paid targets remain payment_required. No paid submission, wallet signing or blockchain transaction. A prepared packet is not provider acceptance.
