This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Common questions
Is Placement API safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
You need to fill in: Authorization
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 2 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Spree Commerce: open-source B2B and marketplace ecommerce, Stripe MCP, MCP Cn Commerce

- MCP endpoint:
https://api.placementapi.com/mcp(streamable HTTP, Bearer API key) - OpenAPI: https://api.placementapi.com/openapi.json · Field semantics: https://api.placementapi.com/v1/schema
- Live market data: https://placementapi.com/data · Prices by type, DR and topic: https://placementapi.com/pricing
This repository holds the TypeScript client (sdk/, published to npm as placementapi) and the MCP registry manifest (server.json). The service itself is not open source.
Connect the MCP server
# Claude Code
claude mcp add --transport http placement-api https://api.placementapi.com/mcp \ --header "Authorization: Bearer $PLACEMENT_KEY"
// Cursor / Windsurf / any host that takes a JSON config

Tools
| Tool | What it does |
|---|---|
search_placements | Search ~550k priced placements deduplicated by domain, with verification, score and price plausibility on every row |
plan_links | A brief in (links, topic, DR, budget, strategy) → a costed plan of named domains, each with why, held at price for four hours |
compare_domain | Everything about one publisher: listings and spread, verification, web-graph, survival, outcomes, Placement Score, market reference |
target_profile / gap_map | Your page's backlink profile and the competitor links you can reproducibly buy, priced |
keyword_winners | What the sites that rank for a keyword look like, and what they buy |
place_order · submit_content · write_it_for_me | Order at the held price; supply the article, let the publisher write it, or have it written |
list_orders · campaign_status · order_outcome | Fulfilment, live checks and observed rank movement (observed, never attributed) |
standing_orders · create_standing_order | Recurring plans; auto-placement can only be enabled from the dashboard |
check_balance · cancel_order |
Use the SDK
npm i placementapi
import { PlacementApi } from "placementapi";
const api = new PlacementApi({ apiKey: process.env.PLACEMENT_KEY! }); const quote = await api.quote({ links: 5, topic: "finance", dr_min: 50, strategy: "safest" }); for (const l of quote.lines) console.log(l.domain, l.price_credits, l.verification, l.why.join(" · "));
See sdk/README.md.
Things worth knowing
- Credits are US cents. Prices on a quote are held for four hours; order with the
quote_idto pay the held price. - `verification` says whether a domain's authority is real:
ok,suspect(high link authority with no organic footprint — what a link farm looks like) orunverified.quality_reasonsnames which of five tests fired. Method: https://placementapi.com/research/quality-methodology - Suppliers are never identified. You see counts and spreads, never who. That is a product rule, not a gap.
- `why[]` on every line is the factual basis for the pick, in sentences an agent can repeat.
