## What is Claude Cowork?

Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools.
With Composio Connect, Cowork can securely access apps like Semrush through MCP without you sharing account credentials directly with the agent.

## What is the Semrush MCP server, and what's possible with it?

The Semrush MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Semrush account. It provides structured and secure access to your SEO, keyword, and advertising analytics, so your agent can perform actions like keyword research, competitor analysis, backlink audits, and ad copy retrieval automatically on your behalf.
- Comprehensive keyword research and reporting: Let your agent fetch broad match keywords, generate batch keyword overviews, and analyze key SEO metrics like search volume and difficulty in real time.
- Competitor and backlink analysis: Ask your agent to pull backlink profiles, perform batch comparisons of domains, and summarize backlink authority and link types for competitive intelligence.
- Ad campaign and copy insights: Have the agent retrieve unique Google Ads copies for any domain, helping you benchmark and optimize your own ad strategies based on real competitor data.
- Content and category profiling: Enable your agent to analyze and categorize domains or URLs, surfacing topic strengths and audience focus areas for smarter content planning.
- Anchor text and authority monitoring: Direct your agent to report on anchor text distributions and authority score profiles, giving you actionable insights for improving link-building efforts.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `SEMRUSH_ACCOUNT_UNITS_BALANCE` | Check Semrush account units balance | Tool to fetch the remaining Semrush Standard API units for the authenticated account. Use this before launching large batches of Semrush report requests to preflight and fail fast if units are exhausted or below a required threshold. |
| `SEMRUSH_ADS_COPIES` | Get ad copies | Retrieves unique ad copies Semrush has observed for a specified domain from a regional database, detailing ads seen in Google's paid search results. Results are a sampled subset, not a complete picture of the domain's advertising. Response is returned as a CSV-like string; parse columns (e.g., Tt, Ds) using the pipe or semicolon delimiter. |
| `SEMRUSH_ANCHORS` | Get anchor texts | Use this action to get a CSV report of anchor texts for backlinks pointing to a specified, publicly accessible domain, root domain, or URL. |
| `SEMRUSH_AUTHORITY_SCORE_PROFILE` | Get authority score profile | Retrieves the Authority Score (AS) profile for a specified target, showing the count of referring domains that link to the target for each AS value from 0 to 100. |
| `SEMRUSH_BACKLINKS` | Get backlinks | Fetches backlinks for a specified domain or URL as a semicolon-delimited CSV string (parse with `sep=';'`); allows customization of columns, sorting, and filtering. Consumes Semrush API credits per request. Ensure `display_limit` surpasses `display_offset` when an offset is used, and note the `urlanchor` filter may have limitations for targets with extensive backlinks. |
| `SEMRUSH_BACKLINKS_OVERVIEW` | Backlinks overview | Provides a semicolon-delimited (sep=';') CSV summary of backlinks, including Authority Score and link type breakdowns, for a specified and publicly accessible domain, root domain, or URL. A result of 'ERROR 50 :: NOTHING FOUND' means the target has no data in the database and is a valid zero-result response. |
| `SEMRUSH_BATCH_COMPARISON` | Batch comparison | Compares backlink profiles for multiple specified targets (domains, subdomains, or URLs) to analyze and compare link-building efforts. |
| `SEMRUSH_BATCH_KEYWORD_OVERVIEW` | Batch keyword overview | Fetches a keyword overview report from a Semrush regional database for up to 100 keywords, providing metrics like search volume, CPC, and keyword difficulty. Response is CSV-like text (not JSON); parse accordingly. Returns literal string 'ERROR 50 :: NOTHING FOUND' for keywords with no data in the selected database — treat as zero results and fall back to SEMRUSH_KEYWORD_OVERVIEW_ONE_DATABASE or SEMRUSH_KEYWORD_OVERVIEW_ALL_DATABASES for those terms. |
| `SEMRUSH_BROAD_MATCH_KEYWORD` | Broad match keyword | Fetches broad match keywords for a given phrase. Response is CSV-like text (not JSON); parse by splitting on line breaks and delimiters. `display_sort` and `display_filter` parameters are defined but currently not utilized by the API call. |
| `SEMRUSH_CATEGORIES` | Get categories | Retrieves categories and their 0-1 confidence ratings for a specified domain, subdomain, or URL, with results sorted by rating. Response is returned as semicolon-separated text in a single 'data' field requiring parsing before use. Some niche or atypical targets may return no category data. |
| `SEMRUSH_CATEGORIES_PROFILE` | Get categories profile | Retrieves a profile of content categories from referring domains for a specified target, analyzing its first 10,000 referring domains and sorting results by domain count. |
| `SEMRUSH_COMPETITORS` | Get competitor data | Retrieves a CSV-formatted report of competitors for a specified target (root domain, domain, or URL) based on shared backlinks or referring domains. Output is a CSV string; use display_limit and display_offset to paginate without silent truncation. |
| `SEMRUSH_COMPETITORS_IN_ORGANIC_SEARCH` | Get competitors in organic search | Use to get a domain's organic search competitors from Semrush as a semicolon-separated string; `display_date` requires 'YYYYMM15' format if used. |
| `SEMRUSH_COMPETITORS_IN_PAID_SEARCH` | Get competitors in paid search | Retrieves a list of a domain's competitors in paid search results from a specified regional database. |
| `SEMRUSH_DOMAIN_AD_HISTORY` | Get domain ad history | Retrieves a domain's 12-month advertising history from Semrush (keywords bid on, ad positions, ad copy) for PPC strategy and competitor analysis; most effective when the domain has ad history in the selected database. |
| `SEMRUSH_DOMAIN_ORGANIC_PAGES` | Get domain organic pages | Fetches a report on a domain's unique organic pages ranking in Google's top 100 search results, with options for specifying database, date, columns, sorting, and filtering. Response is semicolon-separated CSV text in a single `data` field requiring explicit parsing. The literal response `ERROR 50 :: NOTHING FOUND` means zero results for that domain/database combination, not a system error. Traffic metrics (e.g., `Tr`) are modeled estimates incompatible with first-party analytics data. |
| `SEMRUSH_DOMAIN_ORGANIC_SEARCH_KEYWORDS` | Get domain organic search keywords | Retrieves organic search keywords for a domain from a specified Semrush regional database; `display_positions` must be set if `display_daily=1` for daily updates. Response is semicolon-delimited CSV text (parse with sep=';', cast numeric columns before aggregations). A response of 'ERROR 50 :: NOTHING FOUND' indicates no data for the domain in the selected database — treat as a valid zero-result. |
| `SEMRUSH_DOMAIN_ORGANIC_SUBDOMAINS` | Get domain organic subdomains | Retrieves a report on subdomains of a given domain that rank in Google's top 100 organic search results for a specified regional database. |
| `SEMRUSH_DOMAIN_PAID_SEARCH_KEYWORDS` | Get domain paid search keywords | Fetches keywords driving paid search traffic to a specified, existing domain using a supported Semrush regional database. |
| `SEMRUSH_DOMAIN_PLA_SEARCH_KEYWORDS` | Get PLA search keywords for a domain | Retrieves Product Listing Ad (PLA) search keywords for a specified domain from a Semrush regional database. |
| `SEMRUSH_DOMAIN_VS_DOMAIN` | Compare domains | Analyzes keyword rankings by comparing up to five domains to find common, unique, or gap keywords, using specified organic/paid types and comparison logic in the `domains` string. |
| `SEMRUSH_HISTORICAL_DATA` | Get historical data | Retrieves monthly historical backlink and referring domain data for a specified root domain, returned as a time series string with newest records first. |
| `SEMRUSH_INDEXED_PAGES` | Get indexed pages | Retrieves a list of indexed pages from Semrush for a specified `target` (root domain, domain, or URL) and `target_type`, ensuring `target` is publicly accessible, Semrush-analyzable, and correctly matches `target_type`. Returns CSV-like text output requiring parsing before structured analysis. |
| `SEMRUSH_KEYWORD_DIFFICULTY` | Get keyword difficulty | Determines the Keyword Difficulty (KD) score (0-100, higher means greater difficulty) for a given phrase in a specific Semrush regional database to assess its SEO competitiveness. Returns CSV-formatted text; parse before programmatic use. |
| `SEMRUSH_KEYWORD_OVERVIEW_ALL_DATABASES` | Keyword overview all databases | Fetches a keyword overview from Semrush for a specified phrase, including metrics like search volume, CPC, and competition. Response is returned as a CSV-like string; parse headers and rows into a structured table before extracting values like Nq, Cp, or Kd. |
| `SEMRUSH_KEYWORD_OVERVIEW_ONE_DATABASE` | Get keyword overview for one database | Fetches a keyword summary for a specified phrase from a chosen regional database. Returns CSV-like text (not JSON) with column headers matching `export_columns` codes (e.g., 'Ph', 'Nq', 'Kd'); parse headers and rows into structured data before use. A plain-text 'ERROR 50 :: NOTHING FOUND' response indicates zero results, not a transport error. |
| `SEMRUSH_KEYWORDS_ADS_HISTORY` | Get keywords ads history | Fetches a historical report (last 12 months) of domains advertising on a specified keyword in Google Ads, optionally for a specific month ('YYYYMM15') or the most recent period, returning raw CSV-like data. |
| `SEMRUSH_ORGANIC_RESULTS` | Get organic results | Retrieves up to 100,000 domains and URLs from Google's top 100 organic search results for a keyword and region, returning a raw string; use `display_date` in 'YYYYMM15' format (day must be '15') for historical data. |
| `SEMRUSH_PAID_RESULTS` | Get paid search results | Fetches domains ranking in Google's paid search results (AdWords) for a specified keyword and regional database. |

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Semrush MCP?

With a standalone Semrush MCP server, the agents and LLMs can only access a fixed set of Semrush tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Semrush and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Claude Cowork?

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Semrush tools.

### Can I manage the permissions and scopes for Semrush while using Tool Router?

Yes, absolutely. You can configure which Semrush scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Semrush data and credentials are handled as safely as possible.
