| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `calculate_max_contribution`

- 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
Calculates the most a person can contribute for a year given age (on Dec. 31), plans held (401k, 403b, 457b, tsp, simple, ira, hsa_self, hsa_family) and optional wages. Applies the age 50+ catch-up, the SECURE 2.0 age 60-63 super catch-up (eligible only if age 60, 61, 62 or 63 at year end; 64 drops back), the HSA $1,000 catch-up at 55, the shared 402(g) limit across 401(k)/403(b)/TSP/SIMPLE, the separate 457(b) limit, and the compensation cap. With prior_year_fica_wages it tells whether catch-ups must be Roth under SECURE 2.0 section 603 (2026: over $150,000 of 2025 FICA wages).
```

## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `compare_years`

- The name "compare_years" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Shows each retirement, IRA, HSA and Social Security figure for two years side by side with the dollar and percent change: 401(k) deferral, catch-ups, 415(c), compensation limit, HCE threshold, SIMPLE, IRA, Roth catch-up threshold, HSA, wage base, earnings test and COLA. Items the IRS has not yet published (2027 plan limits on 2026-11-02) come back as null, never estimated.
```

### `get_contribution_limits`

- The name "get_contribution_limits" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns official IRS contribution limits for 2025, 2026 and 2027: 401(k)/403(b)/TSP and 457(b) elective deferral ($24,500 for 2026), age 50+ catch-up ($8,000 for 2026), the SECURE 2.0 age 60-63 super catch-up ($11,250), IRA limit and catch-up ($7,500 + $1,100 for 2026), SIMPLE limits, 415(c) total ($72,000), 401(a)(17) compensation limit, highly compensated employee threshold, Roth IRA phase-outs, HSA self/family limits (2027: $4,500 / $9,000, Rev. Proc. 2026-24) and the Social Security wage base (2027: $192,300). Also states the Roth catch-up rule status. Figures copied from IRS Notices 2024-80 and 2025-67 and the HSA Rev. Procs. 2027 plan and IRA limits were not yet announced on 2026-11-02 and the tool says so instead of guessing.
```

### `get_social_security_cola`

- The name "get_social_security_cola" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns the Social Security cost-of-living adjustment and related figures from SSA's official annual notice in the Federal Register: 2027 COLA 3.6% (announced October 2026), 2027 taxable maximum (wage base) $192,300, retirement earnings test limits ($25,560 under full retirement age, $67,920 in the year you reach it, for 2027), quarter of coverage, SGA amounts and SSI federal payment. Covers 2025, 2026 and 2027.
