As a local MCP server: npm package
Built from what Official MCP Registry declares.
claude mcp add --env "PACT_COMMUNITY_CHAINWEB_MODE=<YOUR_PACT_COMMUNITY_CHAINWEB_MODE>" --env "PACT_COMMUNITY_WORKSPACE_ROOT=<YOUR_PACT_COMMUNITY_WORKSPACE_ROOT>" --transport stdio chainweb -- npx -y @pact-community/mcp-chainweb[mcp_servers.chainweb]
command = "npx"
args = ["-y", "@pact-community/mcp-chainweb"]
[mcp_servers.chainweb.env]
PACT_COMMUNITY_CHAINWEB_MODE = "<YOUR_PACT_COMMUNITY_CHAINWEB_MODE>"
PACT_COMMUNITY_WORKSPACE_ROOT = "<YOUR_PACT_COMMUNITY_WORKSPACE_ROOT>"{
"mcpServers": {
"chainweb": {
"command": "npx",
"args": [
"-y",
"@pact-community/mcp-chainweb"
],
"env": {
"PACT_COMMUNITY_CHAINWEB_MODE": "<YOUR_PACT_COMMUNITY_CHAINWEB_MODE>",
"PACT_COMMUNITY_WORKSPACE_ROOT": "<YOUR_PACT_COMMUNITY_WORKSPACE_ROOT>"
}
}
}
}Replace the values in angle brackets with your own. We show the names of the settings, never values.
Optional settings it also lists: PACT_COMMUNITY_CHAINWEB_BASE_URL, PACT_COMMUNITY_CHAINWEB_NETWORK_ID, PACT_COMMUNITY_CHAINWEB_PROFILE.
We do not store launch arguments. If the server needs any, its own documentation names them.

Found by meaning, not by shared code or a shared repository: similar plugins stay separate products, and this is not a review or a recommendation.
Is this your plugin?
Prove you maintain it with a file in its repository, a file on your domain or a DNS record. You get alerts when a marketplace lists it, drops it, changes its verified mark or what it asks for, and can put its remote endpoint on monitoring as a web service.
Data comes from the Official MCP Registry (registry.modelcontextprotocol.io), CC0 1.0. Figures come from our own regular passes over the marketplaces, last read on . We publish no contact details for plugin publishers.
