Stitching together raw APIs for every SEO task wastes engineering time and leaves agents fragile at scale.
Months of integration debt
Building on raw APIs from Ahrefs, Surfer, and Apollo separately means months of glue code before your agent does anything useful.
No unified tool layer exists
Generic API providers give you endpoints but no composable SEO workflow — research, produce, publish, and index are all disconnected.
Self-hosted MCP servers break in production
Running your own MCP infrastructure means every restart, patch, or scaling event falls on your team to handle.
The fix
One Hosted MCP Server. Every SEO Tool Ready.
CitationBench's hosted MCP server at mcp.citationbench.com/mcp gives developers and agencies ~35 production-ready tools across research, content production, distribution, and agent orchestration — callable from Claude Code, Cursor, Windsurf, and ChatGPT Apps today.
Every SEO Tool Your Agent Needs
Five feature areas cover the full marketing ops workflow — from keyword discovery and content production to indexing, link building, and durable agent jobs.
MCP Infrastructure
Hosted MCP Server Ready to Connect
Connect to mcp.citationbench.com/mcp in one command. Tools span research.*, produce.*, indexing.*, link_building.*, and agent.* namespaces — no infrastructure to manage.
- 35 tools, zero self-hosting
- Works with Claude Code and Cursor
- Namespaced research and produce tools
Agent Orchestration
Invoke Full SEO Agents via MCP
Call agent.invoke from any MCP client to run named agents like brand-bootstrap. Supports multi-turn continuation, real-time SSE streaming, and human approval gates mid-workflow.
- Bootstrap a brand in 20 minutes
- SSE streaming for real-time events
- Approval gates at any agent step
Research Tools
Keyword Research Callable from Your Agent
Run research.keyword.research directly from your MCP client. Discovers, clusters, and labels keyword sets from a seed URL. Results persist automatically for content production steps.
- Seed URL or keyword list input
- Results persisted for downstream use
- Bulk create via research.keyword.bulk_create
Agency Architecture
Multi-Workspace Support for Agency Clients
Manage every client brand from one master API key. Pass X-Workspace-Id to isolate keywords, content, campaigns, and settings per client — no separate credentials per workspace.
- Single API key, N client workspaces
- Scoped via X-Workspace-Id header
- Bulk actions across all workspaces
Reliability
Durable Jobs That Survive Restarts
All agent invocations are backed by durable Cyclonic workers. Cancel via agent.invocations.cancel, resume via agent.invocations.continue. Jobs survive process restarts and are fully auditable.
- Backed by Cyclonic worker system
- Cancel or resume any job
- Not fire-and-forget LLM calls
How it works
From sign-up to first call in five minutes.
Sign up and get your key
An `sk_test_*` key lands in your dashboard instantly. No demo gate — start calling real endpoints with shape-complete responses.
Add the MCP server or hit REST
`claude mcp add citationbench https://mcp.citationbench.com/mcp` from Claude Code, Cursor, or any MCP client. Or `curl` against `api.citationbench.com/v1/*` directly.
Run a tool or invoke an agent
Every tool returns shape-complete demo data without auth, so your agent works before the user signs up. Tools across research, production, indexing, link-building, and agents.
Scope to a workspace and ship
Add `X-Workspace-Id: ws_***` to scope per client. Switch to a live `sk_live_*` key when you're ready. Same API surface, same SDK.
