For AI agents — MCPBundles Directory API
Recommended: Directory API v1 over HTTP for detail and anonymous invoke when eligible (not MCP JSON-RPC on the publisher URL; no user MCPBundles credentials on v1).
GET https://www.mcpbundles.com/api/directory/v1/servers/happycluster-mcp-4adf19fe35
GET https://www.mcpbundles.com/api/directory/v1/servers/happycluster-mcp-4adf19fe35?live=1 (optional live refresh)
GET https://www.mcpbundles.com/api/directory/v1/servers/happycluster-mcp-4adf19fe35/tools/<tool> (one tool: schema + invoke.url)
POST https://www.mcpbundles.com/api/directory/v1/servers/happycluster-mcp-4adf19fe35/tools/{tool}
POST body: flat JSON of tool argument names and values; not an arguments wrapper. Replace {tool} with a tool name from GET detail.
Restricted agent shell (ChatGPT Codex desktop, some IDE sandboxes):
Default command sandboxes often block outbound network. curl exit 6 or "Could not resolve host" for www.mcpbundles.com is usually sandbox DNS — not evidence this site is down.
Retry the same Directory API GET with sandbox_permissions "require_escalated" and a one-sentence justification on the shell tool (Codex on-request approval). Do not tell the user the site is unreachable from sandbox curl alone.
Example justification: Run the public MCPBundles Directory API search outside the command sandbox to complete the user's MCP server lookup.
If the agent has browser access (e.g. Codex @Browser): open https://www.mcpbundles.com/?q=<query> or stay on this page — no shell network needed. Use WebMCP search_mcp_servers then get_mcp_server (document.modelContext / page tools; refresh with fetchTools or getTools if a tool id is missing from the snapshot). Read-only directory search; same index as Directory API v1 GETs. Neither WebMCP nor Directory API v1 uses user MCPBundles credentials.
Without a browser: after escalated curl fails, use GET https://www.mcpbundles.com/?q=<query> with Accept: text/markdown for ranked results.
Hub MCP (connected session): discover_mcp_servers — same filter semantics as search_mcp_servers.

Search HappyCluster architecture pattern hubs by free-text query (e.g. "timber pavilion", "london brick facades"). Returns ranked hubs with kind, lede, matched facets, and canonical URLs.
Search Patterns — Search HappyCluster architecture pattern hubs by free-text query (e.g. "timber pavilion", "london brick facades"). Returns ranked hubs with kind, lede, matched facets, and canonical URLs.
Get Pattern — Get a full pattern node by slug: facets, related hubs, lineage parents, facet groups, provenance, and evidence query pointer.
Compare Patterns — Contrast two patterns: shared neighbors (jaccard similarity), shared lineage, and facet differences. For "when X vs when Y" answers.
Find Firms — Find architecture firms whose portfolio images evidence a pattern. Optional region filter.
Find Similar Images — Given a portfolio image UUID, return visually similar images (pgvector nearest-neighbor), each labeled with firm and pattern hubs.
Get Hiring Market — Aggregate hiring market snapshot for architecture studios: active signals, postings, firms, top cities/roles/seniority, salary ranges, 12-month trend.
Get Firm Hiring Signals — Active hiring signal for a specific firm (by slug): postings with position, location, seniority, role, salary.
Semantic Search — Visual-intelligence search: embed a text query via Vertex AI, then pgvector cosine search across ALL public portfolio images. Finds images by content description ("warm minimal timber kitchen") — not keyword matching. Each hit includes similarity %, firm, caption, materials, and hiring status. Optional scope="caption-details" switches to lexical search over surprising_detail + environmental_context_note + summary ("find urban-infill projects") — keyword-AND, deterministic, no embedding cost. (To
Get Firm — Full firm detail by slug: name, location, website, project locations, top caption facets (materials, visual identifiers, facade systems), image count, and portfolio URL.

Operate HappyCluster?
This server appears in the MCPBundles directory. Verify you operate it to take over the listing — name, description, logo, contact email, and skill content. We email a 6-digit code to a maintainer address your server publishes in /.well-known/security.txt or /.well-known/mcpbundles.json. Free, takes about a minute.
MCPBundles publishes this directory for MCP discovery. Except where we host or operate an offering, third-party services run under their own terms. Product and company names on this page are used in a descriptive, identifying way (including under nominative fair use where applicable); they remain the property of their owners. Nothing here grants you rights in those marks, and nothing here is an offer to sell a third party's services. Terms · Request removal

Other MCP servers in this category from the directory index
Find Similar Firms — Firm-level visual similarity ("Similar Design DNA") via centroid kNN. Default mode returns neighbors with match percentages, hiring status, and open positions. With includeHiring=true it returns the compound payload: similar firms × their open hiring seats × peer pay bands (role/hub/currency filters apply) — "which studios with work like X are hiring for Y role at Z pay?"
Get Firm Facets — All 8 caption facet channels for a firm, frequency-ranked: materials, visual identifiers, facade systems, structural approaches, lighting notes, spatial experiences, atmosphere, and geometry analyses. Answers "what does Studio X actually work with?"
Get Pattern Evidence — Paginated evidence images for a pattern hub — the actual photos that prove the pattern claim, ordered by medoid distance (core members first). Optional media-type filter (assetKind: project_photo/drawing_diagram/model) and viewpoint filter (perspectiveClass: interior/exterior/aerial/detail).
Get Skill Cooccurrence — Skill/tool pairs ranked by lift — "hired as a set" intelligence. Lift > 1 means the pair appears together in job postings more often than chance. Answers "what skills are hired together with Grasshopper?"
Get Firm Reputation — Reputation scores for a firm: overall score, level, review counts, delivery/payment/dispute rates, spark acceptance, and level progress. Due-diligence tool — "is this studio reliable?"
Compose Patterns — Deterministic facet composition: every pattern hub whose slug encodes a material × typology × region intersection. Pure registry logic, no DB. Zero matches = honest "not mined yet" signal with a note.
Get Region — A region's full hub inventory: hubs grouped by tier with counts, dominant materials, and canonical URLs. Answers "what materials and patterns define this region's architecture?"
Get Material Trends — Dated material usage across the caption corpus — a time series of which materials were actually built in each year. Optional material filter (single-material series) and region filter (firm location). Answers "is timber rising or falling?" from real built work.
Search Firms — Search firms by their own words — name, location, long-form description, awards, and founder names. Multi-token AND matching. Optional filters: foundedAfter, foundedBefore, hiringOnly. The firm-search companion to search_patterns.
Get Firm Style Profile — A firm's style narrative from its captions: frequency-ranked style tags, up to 3 verbatim style_reading samples, and the firm's E-E-A-T description. Aggregated evidence — no synthesis.
Get Site Context Firms — Firms with caption-verified site-context work. Joins environmental_context_note (site context prose) with materials and firm location. Answers "who has done timber waterfront pavilions?" or "who builds in urban infill contexts?" Presets match the field's actual vocabulary: urban, suburban, rural, coastal, waterfront, forested, hillside, campus, park, courtyard, historic, industrial — or a free-text phrase.
Get Program Expertise — Firms with caption-verified building-program expertise. Joins inferred_program with firm profiles. Answers "which firms have actually built libraries?" — evidence from captioned work, not marketing claims.
Get Award Landscape — Award-winning firms joined with their open hiring positions. Answers "which award winners are hiring juniors now?" — prestige × opportunity. Optional award filter (e.g. "Pritzker") and hiringOnly toggle.
Get My Memory State — The authenticated user's 2nd-brain memory graph: lit/locked/fogged firms with decay weights and freshness buckets (fresh > 0.8, fading ≥ 0.3, fogged < 0.3). PRIVATE — requires user auth (Firebase session or OAuth Bearer). Returns a structured error when unauthenticated.
Get My Bookmarks — The authenticated user's saved library (2nd Brain bookmarks): saved images and firms with hydrated metadata and hiring status. PRIVATE — requires user auth. Returns a structured error when unauthenticated.
Get My Matches — The authenticated user's stored portfolio↔job match results: match scores, job details, salaries, timestamps. PRIVATE — requires user auth. Returns a structured error when unauthenticated.
