The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
exact_search ~240
Exact 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 discovered value containing a colon, GSA's exact-field search can return only the text before the colon. This tool uses literal keyword search instead and accepts its statistics only when the complete, non-approximate requested-field aggregation proves every rate row has the exact value. If that cannot be verified, it withholds the misleading population and gives keyword_search recovery guidance. Source statistics remain unchanged; empty results and thin samples retain their limits.

igce_benchmark ~410
Get 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_Facility / Virtual; counts only, prices are pooled across sites), and outlier bounds. GSA's keyword search matches labor_category, vendor_name and idv_piid. The returned statistics pool all matching rate rows, including unrelated labor titles when a vendor name or contract number matches the phrase. Check population_scope and matched_titles before using the statistics. off_title_matches_detected flags observed titles that do not match the requested phrase; title_only_population_verified is false when the title aggregation is missing, empty, truncated or approximate. A title containing the phrase is not necessarily the exact grade: 'Registered Nurse I' also matches Nurse II, III and IV. Check exact_title_population_verified, exact_title_rate_count and non_exact_title_examples before treating a pool as that specific title. For title-only rates, call suggest_contains on labor_category to discover an exact title, then exact_search on labor_category. Different spellings remain separate searches ('Cyber Security Analyst' vs 'Cybersecurity Analyst'). Statistics are on current-year ceiling rates (current_price), not next-year or option-year prices. These are not-to-exceed ceiling rates, not prices paid. Ceiling-rate comparisons alone do not establish a proposed price's reasonableness. Optional filters: education_level, experience_min/max, business_size ('S' or 'O'), sin (e.g. '541611'), security_clearance ('yes' or 'no').

keyword_search ~434
Search 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 breakdown, business size) covering the FULL result set even when individual hits are capped at 10,000. Important notes: - These are NTE (not-to-exceed) ceiling rates, not prices paid - Rates are fully burdened hourly rates from GSA MAS contracts - Data refreshes nightly from vendor price proposal tables - Use P50 from percentiles for median (more accurate than median_price) Filter parameters: - education_level: AA, BA, HS, MA, PHD, TEC (pipe-delimited for OR: 'BA|MA') - experience_min/max: years of experience range - price_min/max: hourly rate range in USD - business_size: 'S' (small) or 'O' (other/large) - security_clearance: 'yes' or 'no' - sin: Special Item Number (e.g., '54151S' for IT Professional Services) - worksite: NOT supported (the v3 API silently ignores it; passing a value raises so callers are not handed unfiltered data) ordering: current_price, labor_category, vendor_name, education_level, min_years_experience, next_year_price, idv_piid, business_size. sort: 'asc' or 'desc'. exclude: pipe-delimited hit _id values to exclude from results and stats.

price_reasonableness_check ~400
Evaluate 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_SEARCH_FIELDS with no verdict when off-title matches are detected, or UNVERIFIED_POPULATION with no verdict when the title list is missing, empty, truncated or approximate. Discover an exact title with suggest_contains, then use exact_search on labor_category for title-only rates. Filters match igce_benchmark, including sin and security_clearance. Returns MIXED_LABOR_TITLES with no verdict when the phrase matches different grades, specialties or title variants; pooled statistics remain visible, with the exact-title count when verified. For example, Nurse I must not be compared as if Nurse II/III/IV rates were the same grade. Use exact_search with its supported education, experience and business-size filters to inspect that title. It does not accept SIN or clearance filters; check those requirements in the returned records and retain paging limits. A verified exact-title population with at least 20 rates returns z-score, median comparison, IQR position and delta from average. The z-score is null when the mean or standard deviation is unavailable or variance is zero. Missing means produce null average deltas. A verified exact-title population with fewer than 20 rates returns LOW_SAMPLE without a high/low verdict; zero rates return NO_DATA. Statistics compare not-to-exceed ceiling rates, not prices paid, and do not by themselves establish price reasonableness or performance risk.

sin_analysis ~215
Get 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 does not return individual rate rows or per-title prices; for what a title costs on the SIN, call igce_benchmark(title, sin=...). When GSA's 500-title list is cut off, labor_categories.distinct is null and records_in_titles_not_listed counts the rates under titles not listed. Common SINs for professional services (live-verified to return records): - 54151S: IT Professional Services - 541611: Management and Financial Consulting - 541715: Engineering R&D - 541330ENG: Engineering Services - 561210FAC: Facilities Maintenance and Management - 611430: Training

suggest_contains ~156
Discover 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 values, most records first. When more values match, truncated is true and other_records counts the records under values not shown; use a longer term to narrow the list. Example workflow: 1. suggest_contains('vendor_name', 'booz') -> finds 'Booz Allen Hamilton Inc.' 2. exact_search('vendor_name', 'Booz Allen Hamilton Inc.') -> all their rates

vendor_rate_card ~578
Get 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 sort. Stop only when has_more is false, then combine the pages and match the requested roles client-side. If you stop early, say clearly that the results are partial, report the fetched returned_range against total_rates, and explain that later pages may contain additional matching roles or rates. Do not claim a role is absent or present a complete role-specific rate range from a partial card. Auto-discovers the exact vendor name via suggest-contains, then pulls their rate records. Returns labor categories, rates, education levels, experience requirements, SINs, contract numbers, contract end dates, and worksite. A vendor often lists the same category twice at two prices, one for work at the customer's site (Customer_Facility) and one at the contractor's site (Contractor_Facility); check worksite before comparing. Pass a partial name (e.g., 'booz' for Booz Allen Hamilton). The tool finds the exact registered name automatically. Use part of the legal name, not an acronym ('Science Applications', not 'SAIC'). total_rates counts rate rows, not titles: one title can have several rows (worksite, contract, SIN). distinct_labor_categories is the number of distinct titles (case-sensitive); when a vendor has more than 500 it is null and distinct_labor_categories_min gives the floor. Large vendors span many pages: Booz Allen Hamilton carries ~1,900 rate rows (more than 500 distinct titles). The default page_size is 100 (~23KB) because a 500-row page for a vendor that size is ~114KB and overflows MCP client output limits. Rows are ordered by labor_category ascending by default, so a partial card is alphabet-biased and may omit all requested roles on page 1. There is no server-side way to inters…

What is the GSA CALC+ MCP server?
GSA CALC+ is an MCP server listed in the public MCP registry as com.1102tools/gsa-calc-mcp. GSA CALC+ awarded labor ceiling rates from more than 230,000 MAS contract records. 8 tools. This page covers its PyPI package (gsa-calc-mcp).
Is the GSA CALC+ MCP server safe to use?
GSA CALC+ scores 73 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the GSA CALC+ MCP server expose?
GSA CALC+ exposes 8 tools: keyword_search, exact_search, suggest_contains, filtered_browse, igce_benchmark, and 3 more. Their descriptions and schemas cost roughly 2,573 tokens of context every time the server is loaded.
Is the GSA CALC+ MCP server still maintained?
GSA CALC+ is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the GSA CALC+ MCP server under?
GSA CALC+ declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
What did VerifyMCP test on the GSA CALC+ MCP server?
VerifyMCP ran 15 checks on GSA CALC+, covering Known CVEs, Install scripts, Dependency health, Source repository and 11 more. One item could not be completed, a gap on our side rather than a finding about GSA CALC+: Malware scan. Endpoint Security and Transport & Reachability do not apply to a PyPI package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
