Claude Code: ask. ### `price_reasonableness_check` - The description's first verb is "evaluate": a word for a change. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. - Findings: warn annotation-conflict Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `suggest_contains` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text 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 ``` ## Only reads (6) Looks things up and changes nothing. Claude Code: allow. ### `exact_search` - The name "exact_search" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `filtered_browse` - The name "filtered_browse" says "browse": a word for reading. Description, as the server wrote it: ```untrusted-server-text Browse 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_benchmark` - The description's first verb is "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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` - The name "keyword_search" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `sin_analysis` - The description's first verb is "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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 ``` ### `vendor_rate_card` - The description's first verb is "get": a word for reading. - Findings: info long-description Description, as the server wrote it: ```untrusted-server-text 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 intersect a vendor with a labor-category keyword (the v3 API ignores vendor_name and labor_category as filter fields; live-verified). To find specific categories, page through the full card and match client-side. If the discovery term matches multiple vendors, this tool picks the one with the most rate records and returns a _candidates list so the caller can re-query with a more specific term if needed. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `gsa-calc`: ```json { "permissions": { "allow": [ "mcp__gsa-calc__keyword_search", "mcp__gsa-calc__exact_search", "mcp__gsa-calc__filtered_browse", "mcp__gsa-calc__igce_benchmark", "mcp__gsa-calc__vendor_rate_card", "mcp__gsa-calc__sin_analysis" ], "ask": [ "mcp__gsa-calc__suggest_contains", "mcp__gsa-calc__price_reasonableness_check" ], "deny": [] } } ```
