Server icons

The 30 server icons in MCP, described

MCPmcp

MCP, the Model Context Protocol — the standard a model uses to talk to tools and data sources.

Auth flowmcp-auth-flow

The rack with a lock in it — the steps a client goes through to be let in.

Cancel requestmcp-cancel-request

The rack with a slash in it — a request the client no longer wants answered.

Capability negotiationmcp-capability-negotiate

The rack with an arrow pointing both ways — client and server agreeing on what each can do.

Server discoverymcp-discovery

The rack with an eye in it — a server found by name, not by address.

Error codemcp-error-code

The rack with a line and a cross under it — the number that says what went wrong.

Gatewaymcp-gateway

The rack with two posts in it — the one door many servers sit behind.

Multi-servermcp-multi-server

The rack with two slots in it — several servers behind one client.

MCP OAuthmcp-oauth

MCP OAuth — the server proves who may call it with a token from an authorisation flow.

Progress tokenmcp-progress-token

The rack with a bar in it — the token a long request reports its progress against.

Prompt templatemcp-prompt-template

The rack with brackets in it — a prompt with the blanks still to fill.

Proxymcp-proxy

The rack with a relay point on a wire — a server that passes calls on to another.

Rate limitmcp-rate-limit

The rack with a funnel in it — only so many calls let through in a window.

Resource updatemcp-resource-update

The rack with an arrow looping back — a resource the server says has changed.

Retry policymcp-retry-policy

The rack with chevrons up and down — how a failed call is tried again, and how often.

Schema versionmcp-schema-version

The rack with a hash in it — which revision of the protocol the server speaks.

MCP scopemcp-scope

An MCP scope — allowed to do this much and no more, a narrowed grant of permissions.

Scope grantmcp-scope-grant

The rack with a funnel and a check under it — the scopes a client asked for and got.

MCP servermcp-server

An MCP server — the provider that exposes tools, resources and prompts to a model.

MCP server addmcp-server-add

MCP server add — connect and register another server so the model can use it.

MCP server alertmcp-server-alert

MCP server alert — something is wrong with this server and it needs attention.

MCP server checkmcp-server-check

MCP server check — the server answered, is connected and reports healthy.

MCP server devmcp-server-dev

MCP server dev — a server still being written and built, not yet published.

Server healthmcp-server-health

The rack with a heart in it — whether the server is alive and answering.

Server logmcp-server-log

The rack with lines in it — what the server wrote while it ran.

Server metricmcp-server-metric

The rack with bars in it — how much the server is doing, measured.

MCP server offmcp-server-off

MCP server off — the server is disabled, disconnected or stopped.

MCP server testmcp-server-test

MCP server test — run the server against a pretend client before it goes live.

Tool annotationmcp-tool-annotation

The rack with a tag in it — hints about a tool: read-only, destructive, idempotent.

Tool timeoutmcp-tool-timeout

The plug with a clock on it — a tool call given up on after so long.

In code, each is one import — import { Mcp } from "@iconmind/react/icons/mcp" — and the same name in Vue, Svelte, Solid, Preact, React Native, Astro, Blade and Flutter.
