Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 123 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name estuary-flow-mcp.

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

  • Not measured
    Consistent (p95)

    95th percentile 123 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

    31 of 31 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.

  • 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 2026-11-10T23:33:23.964908Z, within 180 days.

Capabilities

Tools 15

estuary_create_draft

WRITE: create a new empty draft workspace (a staging area for catalog changes; does not affect live pipelines). Estuary control-plane: POST /drafts. Returns the created row.

Discovered
estuary_get_catalog_spec

Get one live catalog entity by its exact catalog_name, including the full serialized `spec` and compiled `built_spec`. Estuary control-plane view live_specs_ext. PostgREST: GET /live_specs_ext?catalog_name=eq.<name>&limit=1.

Discovered
estuary_get_catalog_stats

Get usage/throughput stats for one catalog entity — bytes & docs read/written (both directions), usage_seconds, warnings/errors/failures, and txn_count — per time grain. Optionally bound by a timestamp range. Estuary control-plane view catalog_stats. PostgREST: GET /catalog_stats.

Discovered
estuary_get_tenant

Get the user's tenant(s) — quotas (tasks/collections), billing tiers, recurring charge, trial start, and payment provider. Estuary control-plane table tenants. PostgREST: GET /tenants.

Discovered
estuary_list_catalog

List live catalog entities (captures, collections, materializations, tests) the user can read, with connector + last-publication metadata. Optionally filter by a catalog-name prefix and spec_type. Estuary control-plane view live_specs_ext. PostgREST: GET /live_specs_ext.

Discovered
estuary_list_connector_versions

List available versions (image tags) of connectors, with protocol and documentation URL. Optionally filter by connector_id. Estuary control-plane table connector_tags. PostgREST: GET /connector_tags.

Discovered
estuary_list_connectors

List the connector catalog — available capture/materialization Docker connectors, with titles, descriptions, and logos. Optionally filter to recommended connectors. Estuary control-plane table connectors. PostgREST: GET /connectors.

Discovered
estuary_list_discovers

List connector discovery jobs (auto-detecting bindings/resources for a capture). Estuary control-plane table discovers. PostgREST: GET /discovers.

Discovered
estuary_list_draft_specs

List the staged spec entries within a draft (each an insert/replace of a catalog entity pending publication). Estuary control-plane table draft_specs. PostgREST: GET /draft_specs.

Discovered
estuary_list_drafts

List the user's draft workspaces (staging areas for catalog edits before publishing). Estuary control-plane table drafts. PostgREST: GET /drafts.

Discovered
estuary_list_publications

List publication history/status — each publish attempt of a draft; job_status carries the queued/success/failed outcome. Estuary control-plane table publications. PostgREST: GET /publications.

Discovered
estuary_list_roles

List the roles/capabilities the current credential is granted — which catalog prefixes it can read/write/admin. Read-only RPC. Estuary control-plane: POST /rpc/auth_roles.

Discovered
estuary_publish_draft

WRITE (DESTRUCTIVE when dry_run=false): publish a draft. dry_run=true (default) only VALIDATES the draft without changing anything. dry_run=false APPLIES the draft to the LIVE catalog — this can create, modify, or DELETE running data pipelines and their data. Set dry_run=false only when you intend to change live infrastructure. Estuary control-plane: POST /publications. Returns the publication row.

Discovered
estuary_upsert_draft_spec

WRITE: stage (insert or replace) a catalog spec inside a draft. Edits only the draft — live pipelines are unaffected until the draft is published. Estuary control-plane: POST /draft_specs (upsert on draft_id,catalog_name). Returns the staged row.

Discovered
estuary_view_task_logs

Fetch the log lines for a job by its logs_token (a UUID found on a publication, discover, or connector-tag record). Optionally page from a last-seen timestamp. Read-only RPC. Estuary control-plane: POST /rpc/view_logs.
