  and https://documentation.g2.com/docs/g2-mcp-server. Replaces the 2026-05-04
  scaffold, whose per-tier limits were invented defaults G2 does not publish.

description: >-
  G2 publishes exactly one rate limit and it is enforced at the edge, not per
  plan: Cloudflare limits the G2 API to 100 requests per second per source IP
  address. Exceeding it blocks access for 60 seconds before requests resume. The
  G2 MCP server calls the same API and inherits the same limit. G2 publishes no
  per-tier quota, no burst allowance, and no monthly cap, and the OpenAPI
  declares no rate-limit response headers or 429 responses on any of its 62
  operations — so a client has no runtime signal and must infer throttling from
  connection-level blocking.
limit_count: 1
limits:
  - name: Global API rate limit
    scope: source-ip
    metric: requests_per_second
    limit: 100
    timeFrame: second
    enforced_by: Cloudflare (edge)
    on_exceed: Access blocked for 60 seconds before requests can resume.

headers:
  published: false
  limit: null
  remaining: null
  reset: null
  retryAfter: null
  policy: null
  note: >-
    G2 documents no X-RateLimit-*/RateLimit-* response headers and no Retry-After.
    Grep of both OpenAPI documents finds zero rate-limit headers and zero 429
    responses across 62 operations; the only documented 5xx is a 503 on
    createG2ActivateIndustrySearch for LLM/embedding backend failure.
responseCodes:
  throttled: null
  note: >-
    No 429 is declared anywhere in the published contract. The documented
    behaviour on breach is a 60-second block at the Cloudflare edge.
policies:
  - name: Recovery
    description: >-
      After a breach, wait out the 60-second block. Because no Retry-After is
      returned, clients should cap concurrency below 100 rps rather than react to
      a header.
