## MCP tools (5)

### `postgres_call` (~52 tokens)

Call

Call an allow-listed function with named arguments: public.ship_order(bigint): Mark a paid order shipped.

Input parameters:

- `args` (object): The function's named arguments.
- `function` (string, required): An allow-listed function.

### `postgres_describe` (~55 tokens)

Describe

List the tables the agent can read: columns, types, primary keys, row estimates, and which tables are writable and watched.

Input parameters:

- `schema` (string): Only this schema.
- `table` (string): Only this table.

### `postgres_execute` (~100 tokens)

Execute

Run one INSERT, UPDATE, DELETE or MERGE in a transaction Deedglass controls, as a least-privilege role. Writable tables: public.orders, public.refunds.

Input parameters:

- `params` (array): Values for $1, $2 …: strings, integers, booleans or null; at most 100.
- `sql` (string, required): One INSERT, UPDATE, DELETE or MERGE. Use $1, $2 … for values.

### `postgres_query` (~105 tokens)

Query

Run one read-only SQL statement against public and get up to 500 rows back. Read-only: it never commits.

Input parameters:

- `limit` (integer): Return at most this many rows (default and maximum 500).
- `params` (array): Values for $1, $2 …: strings, integers, booleans or null; at most 100.
- `sql` (string, required): One read-only SQL statement (SELECT). Use $1, $2 … for values.

### `deedglass_check_approval` (~157 tokens)

Check a Deedglass approval

Checks whether a person has countersigned an action that Deedglass paused for approval. Call it with the approval_id from a 'Waiting for approval' message. It waits up to wait_seconds (0 to 20, default 10) for the decision, so one call is usually enough. If it was approved, Deedglass runs the original tool call and returns its result. Nothing runs while the approval is pending.

Input parameters:

- `approval_id` (string, required): The approval id, for example apr_01j9zs4k7m2n3p5q6r7s8t9v0w
- `wait_seconds` (integer): How long to wait for a person's decision before answering, in seconds.

## Common questions

### What is the Deedglass MCP server?

Deedglass is an MCP server listed in the public MCP registry as io.github.deedglass/deedglass. Deedglass lets rules decide each AI agent tool call, checks what really changed and seals a record. This page covers its npm package (deedglass).

### Is the Deedglass MCP server safe to use?

Deedglass scores 81 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. 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 Deedglass MCP server expose?

Deedglass exposes 5 tools: postgres_call, postgres_describe, postgres_execute, postgres_query, deedglass_check_approval. Their descriptions and schemas cost roughly 469 tokens of context every time the server is loaded.

### Is the Deedglass MCP server still maintained?

Deedglass 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 Deedglass MCP server under?

Deedglass declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
