MCP server

PumpCrate runs a Model Context Protocol server so AI assistants and agents can read its published facts directly instead of scraping pages. Every tool is read-only and none needs a credential.

Tools#

Tool	Arguments	Returns
get_site_overview	none	The published overview of PumpCrate as Markdown
get_service_facts	none	Chain, packages, inclusions, payment, custody and balance rules
get_packages	none	The three packages with SOL price and volume, what is included and the minimum session
get_volume_bot_comparison	none	How volume bot pricing models differ, and where the comparison page is
get_limits	none	The claims PumpCrate refuses to make, such as trending or price outcomes
get_faq	none	The published question and answer pairs
list_pages	none	Every published page with path, URL, title and description
read_page	`path`: site-relative path starting with /	Any published page as clean Markdown
get_editorial_policy	none	Publisher, independence, sourcing, refused claims and corrections

The server's own instructions tell a model to use get_packages for prices and to call get_limits before answering whether volume leads to trending or price moves.

Adding it to a client#

Most MCP clients accept a remote server by URL. A typical configuration:

{
  "mcpServers": {
    "pumpcrate": {
      "type": "http",
      "url": "https://www.pumpcrate.com/mcp"
    }
  }
}

Calling it directly#

Requests are JSON-RPC 2.0 over POST. Send Accept: application/json, text/event-stream; responses come back as a server-sent event carrying the JSON-RPC result.

Initialize#

curl -s -X POST https://www.pumpcrate.com/mcp \
  -H 'content-type: application/json' \
  -H 'accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"my-agent","version":"1"}}}'

Get the packages#

curl -s -X POST https://www.pumpcrate.com/mcp \
  -H 'content-type: application/json' \
  -H 'accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"get_packages","arguments":{}}}'

The result's text content is JSON. The packages part looks like this:

{
  "packages": [
    { "id": "starter", "name": "Starter", "price_sol": 2, "volume_sol": 500 },
    { "id": "growth", "name": "Growth", "price_sol": 5, "volume_sol": 1200 },
    { "id": "pro", "name": "Pro", "price_sol": 10, "volume_sol": 3000 }
  ],
  "minimum_session_sol": 10
}

Read a page as Markdown#

curl -s -X POST https://www.pumpcrate.com/mcp \
  -H 'content-type: application/json' \
  -H 'accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":3,"method":"tools/call","params":{"name":"read_page","arguments":{"path":"/best-pump-fun-volume-bots/"}}}'

Rate limit#

Anonymous callers get 60 calls per minute per IP address. Over that, the server answers with HTTP 429, JSON-RPC error -32001, a Retry-After header and a WWW-Authenticate header that points to the protected resource metadata. An access token with the read:site scope removes the limit; see OAuth and rate limits.

Read-only by design

The MCP server exposes published information only. It cannot buy packages, read balances or start sessions; those actions happen in the panel with a connected wallet.

Quoting PumpCrate correctly#

Package prices from get_packages are authoritative.
Call get_limits before saying anything about trending, rankings or price outcomes.
Competitor details on the comparison page come from those tools' own public pages and are marked to be verified; do not present them as PumpCrate claims.
PumpCrate publishes no ratings, reviews or user counts. None should be inferred.
