Description from the maker (original English)
GSA CALC+ awarded labor ceiling rates from more than 230,000 MAS contract records. 8 tools.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

keyword_searchSearch GSA CALC+ ceiling rates by keyword. Performs wildcard matching across labor_category, vendor_name, and idv_piid fields. This is the primary search tool for finding rates. Returns matching rate records plus aggregation statistics (wage_stats, percentiles, education breakdow
exact_searchExact match search on a specific field. Use suggest_contains() first to discover the exact field value, then pass it here. The API requires exact string matching -- partial matches return 0 results. Fields: labor_category, vendor_name, idv_piid (GSA MAS contract number). For a di
suggest_containsDiscover exact field values via autocomplete/contains matching. Returns aggregation buckets showing matching values and their record counts. Use this BEFORE exact_search() to find the right value string. Minimum 2 characters required for the search term. GSA lists at most 100 val
filtered_browseBrowse rates with filters only (no search keyword). Useful for market segment statistics: "what do all BA-level rates with 5-15 years experience look like across all of GSA MAS?" Returns rate records plus full aggregation statistics.
igce_benchmarkGet ceiling rate benchmarks for IGCE development. Returns statistical summary for a labor category: count, min, max, avg, median, standard deviation, percentile distribution (P10-P90), education breakdown, worksite counts (worksite_breakdown: Customer_Facility / Contractor_Facili
price_reasonableness_checkEvaluate a proposed hourly rate against GSA ceiling rate distribution. GSA's keyword search matches labor titles, vendor names and contract numbers. Check population_scope: unrelated titles can enter the pooled statistics through a matching vendor or contract. Returns MIXED_SEARC
vendor_rate_cardGet ceiling rates for a specific vendor, one page at a time. For a complete vendor card or a role-specific subset (for example, project managers), fetch every page: while has_more is true, call this tool again with page=next_page and the same vendor_name, page_size, ordering, and
sin_analysisGet rate distribution and statistics for a specific SIN. Returns rate statistics, education breakdown, business size breakdown, and labor_categories for a GSA MAS Special Item Number: the 25 titles with the most rates on the SIN, with counts (exact, case-sensitive titles). It doe

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
Either way works: install it on your computer or connect to the cloud version.
The GitHub repo last changed –, and the latest version (1.0.24) reached the registry 8 days ago.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
