Measurement details

Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 80 ms.

  • Pass
    Valid handshake

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

  • Pass
    Lists tools

    tools/list returned 15 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 80 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 80 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

    59 of 59 parameters have a description (100%). The bar is 80%.

  • Fail
    Safety hints

    15 tools set neither readOnlyHint nor destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Pass
    Source repo linked

    A 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 2026-11-09T19:14:13.497062Z, within 180 days.

  • Not measured
    Open-source licence

    The GitHub licence lookup has not returned an OSI result yet.

Tools

  • account_whoami

    Show the archive account email at api.secondlayer.tools, not the self-host instance.

    Measured

  • batch_query

    Run up to 10 public /v1 reads in one round trip (POST /v1/batch). Each item keeps its own auth/quota/pay-per-call semantics; results return in order with per-item status. Paths must start with /v1/index, /v1/subgraphs, /v1/streams, or /v1/contracts.

    Measured

  • contracts_find

    Discover deployed Stacks contracts conforming to a trait (e.g. "sip-010", "sip-009", "sip-013"). The discovery endpoint for "which contracts implement X". Reads are public.

    Measured

  • contracts_get_abi

    Fetch a single deployed contract's ABI from the registry (prod-safe). Returns the contract's metadata + full ABI (functions, maps, variables, fungible/non-fungible tokens). Returns not_found if the contract isn't in the registry. Use it to inspect a contract before subgraphs_scaffold.

    Measured

  • index_blocks

    List decoded blocks from Index. Reads are keyless.

    Measured

  • index_contract_calls

    List decoded contract calls from the Index (function name, args, result). Set `trait` (e.g. sip-010) to match calls to all contracts conforming to a standard. Note: contract-call cursors are a SEPARATE keyspace from event cursors — they are not interchangeable.

    Measured

  • index_discover

    Discover the Index vocabulary: every event type and its columns, allowed/equality filters, and required-non-null fields (and which types accept `trait`). Read this before building Index queries instead of guessing filters. Anonymous read.

    Measured

  • index_events

    List decoded chain events from the Index by event type. Use this for event types without a dedicated tool (stx_*, ft_mint/burn, nft_mint/burn, print), and for trait-scoped queries: set `trait` (e.g. sip-010) to match all contracts conforming to a standard — pair with contracts_find to discover traits. For ft/nft transfers without a trait prefer index_ft_transfers / index_nft_transfers.

    Measured

  • index_ft_transfers

    List decoded SIP-010 fungible-token transfers from Index. Reads are keyless.

    Measured

  • index_nft_transfers

    List decoded SIP-009 non-fungible-token transfers from Index. Reads are keyless.

    Measured

  • index_print_schema

    Empirical per-topic print payload schemas for a contract, inferred from sampled on-chain events: each topic's fields with observed Clarity types, decoded TS types, subgraph column types, and presence rates. Use before writing print_event subgraph handlers to learn what's on e.data. Anonymous read.

    Measured

  • index_transactions

    List decoded transactions from Index. Filter by type, sender, or contract. Reads are keyless.

    Measured

  • streams_dumps

    List the Streams bulk parquet dumps manifest — coverage range, latest_finalized_cursor, and per-file metadata (block range, row count, size, sha256, signed URL). This is the cold backfill path for downloading all raw data; fetch the file URLs directly (e.g. with DuckDB). Requires the dumps base URL to be configured (SL_STREAMS_DUMPS_URL). For live reads use REST GET /v1/streams/events; for tip/lag use streams_tip.

    Measured

  • streams_tip

    Current canonical chain tip as Streams sees it: block height/hash, burn height, finalized_height, lag_seconds, and the oldest seekable height/cursor for this key's retention window. Call it before a cursor walk to know where the stream ends, and after an ingest to check lag.

    Measured

  • subgraphs_scaffold

    Generate a subgraph from observed print events when available; ABI token transfers or public functions only when the contract has never printed. Review the TypeScript, run subgraphs_test until ok: true with written >= 1, read skipped, then subgraphs_deploy. dryRun is DDL only.
